Chapter 1 - Introduction 1.1 Background The wellhead protection (WHP) plan for the City of Bertha is being amended in cooperation with the Minnesota Department of Health (MDH). The second part of the city’s original WHP Plan was approved by MDH in December 7, 2001. The State WHP Rule requires community water suppliers to amend their plan every 10 years (starting in year 8) so that the plan remains current and reflects any changes to the public water supply system, land use, contaminant issues, etc. that may have occurred during the time the original WHP plan was it place. WHP plans are amended to keep up with both new challenges and new opportunities to protect the public water supply wells and aquifer used by the city. This plan contains specific actions that the city will take to fulfill WHP requirements that are specified under Minnesota Rules, part 4720.5510 to 4720.5590. Also, the support that Minnesota state agencies, federal agencies, Todd County and others will provide is presented to identify their roles in protecting the city’s drinking water supply. The plan is effective for 10 years after the approval date specified by MDH and the city is responsible for implementing its WHP plan of action, as described in Table 9 of this report. Furthermore, the city will evaluate the status of plan implementation at least every two-and-one-half years to identify whether its WHP plan is being implemented on schedule. 1.2 Plan Appendices Much of the technical information that was used to prepare this plan is contained in the appendices but is summarized in the main body of this plan. In particular:

Appendix I contains the first part of the plan, consisting of the delineation of the wellhead protection area (WHPA), the drinking water supply management area (DWSMA), and the vulnerability assessments for the public water supply well(s) and the DWSMA. This part of the plan is summarized in Chapter 3.

Appendix II contains the inventory of potential contamination sources. This inventory is discussed in Chapter 4 in terms of assigning risk to the city’s water supply and is also discussed in Chapter 6, relating to issues, problems or opportunities.

Appendix III contains the contingency strategy to provide for an alternate water supply if there is a disruption caused by contamination or mechanical failure. This information is discussed in Chapter 11.

1.3 Plan Development Milestones: Scoping Two Meeting Held December 7, 2011 (4720.5340, Subp. 1) Scoping Two Letter Dated December 29, 2011 (4720.5340, Subp. 2) WHP Management Plan Submitted to March 14, 2012 Local Units of Government (LGU’s) (4720.5340, Subp. 1) WHP Management Plan Review Received from LGU’s May 14, 2012 (4720.5350, Subp. 2

Management Plan Review Comments Considered May 14, 2012 (4720.5350, Subp. 3) Public Hearing Conducted May 14, 2012 (4720.5350, Subp. 4) WHP Management Plan Submitted to MDH June 14, 2012 (4720.5360, Subp. 1) Final WHP Plan Review & Notice September 14, 2012 (4720. 5360, Subp. 4)

Chapter 2 - Identification and Assessment of the Data Elements Used to Prepare the Plan The data elements that are included in this plan were used to delineate the WHPA and the DWSMA and to assess DWSMA and well vulnerability and document the need for the WHP measures that will be implemented to help protect the city’s water supply from potential sources of contamination. The city met with representatives from MDH on two occasions to discuss data elements that are specified in Minnesota Rules, part 4720.5400, for preparing a WHP plan. (See Part I of the WHP Plan in Appendix I for more information.) The first scoping meeting, held on March 24, 2011 addressed the data elements that were needed to support the delineation of the WHPA, the DWSMA, and the well(s) and DWSMA vulnerability assessments. The second scoping meeting, held on December 7, 2011 discussed the data elements required to 1) identify potential risks to the public water supply and 2) develop effective management strategies to protect the public water supply in relation to well and DWSMA vulnerability. The results of each meeting were communicated to the city by MDH through a formal scoping decision notice. Not all of the data elements listed in the WHP rule had to be addressed in the WHP plan because of the nonvulnerable nature of the city’s source of drinking water. The following table presents the data element assessment results relative to the overall impact that each data element has on the four items listed. Table 1 is the assessment of the present and future implications of the data elements on the four planning activities. The data elements that are marked high (H) are considered to have a direct implication or impact on the activity. Data elements that have an indirect or marginal impact on an activity are shown as moderate (M). A data element that has little if any impact is shown as low (L). The source of the data is shown under “Data Source.” The “Availability of Data” is “Yes” if planning needs are met and “No” if they are not.

Chapter 3 - Delineation of the Wellhead Protection Area, Drinking Water Supply Management Area and Vulnerability Assessments A detailed description of the process used for 1) delineating the WHPA and the DWSMA, and 2) preparing the vulnerability assessments of the city water supply well(s) and DWSMA is presented in the first part of the WHP Plan and included in Appendix I. The City of Bertha requested that MDH do this work and it was performed by Gail Haglund who is licensed as a geoscientist by the State of Minnesota. 3.1 WHPA and DWSMA Delineation Figure 1 shows the boundaries of the WHPA and the DWSMA. The WHPA was delineated using computer simulations of groundwater movement to generate the underground capture zones for city Wells 2 (Unique No. 240649), 3 (Unique No. 603142). The DWSMA boundaries were designated using the following criteria:

Center-lines of highways, streets, roads, or railroad rights-of-ways;

Public Land Survey coordinates;

Property or fence lines;

Center-lines of public drainage systems;

Public utility service lines, and

Political boundaries. 3.2 Well Vulnerability Assessment The construction and water quality obtained from each primary well used by the City of Bertha is included in the assessment of well vulnerability. The vulnerability of the city wells is considered low because they are constructed so that each well is adequately sealed into the borehole and does not pump water that contains human-caused contaminants. 3.3 DWSMA Vulnerability Assessment The low vulnerability assigned to the DWSMA (Figure 1) was determined using geologic, soils, and groundwater chemistry information and indicates that at least 10 feet of clay-rich geological material covers the source water aquifer. (See Part I of the WHP Plan in Appendix 1)

7

Chapter 4 - Establishing Priorities and Assigning Risk to Potential Contamination Sources

The types of potential contamination sources that may exist within the DWSMA were derived from the information collected to satisfy the data element requirements (Chapter 2). The impact assigned to each data element as part of the assessment process (Table 1) was used to assess the types of potential contamination sources that may present a risk to the city’s drinking water supply. The low vulnerability assessment for the DWSMA indicates that, generally, only wells, other types of boreholes, excavations that may reach the aquifer, and certain types of Environmental Protection Agency Class V Wells are likely to impact the city wells.

4.1 Contaminants of Concern None of the human-caused contaminants regulated under the federal Safe Drinking Water Act have been detected at levels indicating that any well itself serves to draw contaminants into the aquifer as a result of pumping. Iron and manganese are naturally occurring contaminants found in the City of Bertha’s water supply. Their presence indicates that the aquifer receives recharge over a long time period and is not likely to be directly impacted by land uses. The City of Bertha is in the process of upgrading their water treatment plant to better sequester iron and manganese from their water supply. 4.2 Inventory Results and Risk Assessment A map and description of the locations of potential contamination sources (wells) is presented in Appendix II. A summary of the results for the IWMZ is listed in Table 2 and Table 3 presents these results for the remainder of the DWSMA. The priority assigned to each type of potential contamination source addresses 1) the number inventoried, 2) its proximity to a city well, 3) the capability of local geologic conditions to absorb a contaminant, 4) the effectiveness of existing regulatory controls, 5) the time required for the City of Bertha to obtain cooperation from governmental agencies that regulate it, and 6) the administrative, legal, technical, and financial resources needed. A high (H) risk potential implies that the potential source type has the greatest likelihood to negatively impact the city’s water supply and should receive highest priority for management. A low (L) risk potential implies that a lower priority for implementing management measures is assigned.

Chapter 5 - Impact of Land and Water Use Changes on the Public Water Supply Well(s) The city estimates that the following changes to the physical environment, land use, surface water, and groundwater may occur over the 10-year period that the WHP plan is in effect (Table 4). This is needed to determine whether new potential sources of contamination may be introduced in the future and to identify future actions for addressing these anticipated sources. Land and water use changes may introduce new contamination sources or result in changes to groundwater use and quality. The anticipated changes may occur within the jurisdictional authority of the city, although some may not. Table 4 describes the anticipated changes to the physical environment, land use, and surface water or groundwater in relationship to the 1) influence that existing governmental land and water programs and regulations may have on the anticipated change, and 2) administrative, technical, and financial considerations of the City of Bertha and property owners within the DWSMA.

Chapter 6 - Issues, Problems, and Opportunities 6.1 Identification of Issues, Problems and Opportunities The City of Bertha has identified water and land use issues and problems and opportunities related to the aquifer used by the city water supply wells, the quality of the well water, or land or water use within the DWSMA. The city assessed input from public meetings and written comments it received, the data elements identified by MDH during the scoping meetings, and the status and adequacy of the city’s official controls and plans on land and water uses, in addition to those of local, state, and federal government programs. The results of this effort are presented in the following table, which defines the nature and magnitude of contaminant source management issues in the city’s DWSMA. Identifying issues, problems and opportunities, including resource needs, enables the city to take advantage of opportunities that may be available to make effective use of existing resources, set meaningful priorities for source management and solicit support for implementing specific source management strategies. 6.2 Comments Received There have been several occasions for local governments, state agencies, and the general public to identify issues and comment on the city’s WHP plan. At the beginning of the planning process, local units of government were notified that the city was going to develop its WHP plan and were given the opportunity to identify issues and comment. A public information meeting was held to review the results of the delineation of the wellhead protection area, DWSMA, and the vulnerability assessments. The meetings of the city’s wellhead protection team were open to the public. Also, a public hearing was held before the completed WHP plan was sent to MDH for state agency review and approval. At this time, no comments have been received on the Bertha WHP Plan.

Well # 2 is 3’ within the R.O.W. of State Hwy. 71. (R.O.W. is 165’ wide from Center.)

Public Water Supply Well may be impacted by MNDOT road work or potential accidents.

Potential damage to the well casing could allow potential contaminants to enter the aquifer and impact the city water supply.

Make MNDOT, local responders aware of well locations & take precautions when working in this area. City moves well out of R.O.W. if well needs to be replaced in the future.

City has no authority over MNDOT R.O.W.

The Bertha High School may construct an irrigation well.

Increased pumping and use of the aquifer.

Increased pumping may potentially impact the aquifer

Encourage use of the city water supply to the extent practical. If the school constructs the irrigation well, encourage water use conservation & protection of the well itself.

The City does not have authority to prohibit the construction of the well. Physical construction of the well is regulated by MDH. DNR issues appropriation permit to regulate water use.

Chapter 7 - Existing Authority and Support Provided by Local, State, and Federal Governments In addition to its own controls, the City of Bertha will rely upon partnerships formed with local units of government, state agencies, and federal agencies with regulatory controls or resource management programs in place to help implement its WHP plan. The level of support that a local, state, and federal agency can provide depends on its legal authority, as well as the resources available to local governments. 7.1 Existing Controls and Programs of the City of Bertha Table 6 shows the legal controls and/or programs that the city has identified to support the management of potential contamination sources within the DWSMA.

Table 6 - Controls and Programs of the City of Bertha

Type of Control Program Description

City of Bertha: Land Use Control Ordinance and Building Permits

Protects the Health, Safety and General Welfare of the community through good planning. Reduces conflicts between different land uses and provides an opportunity to establish standards and guidelines to offset potential risk posed by a land use and / or improper construction practices.

City of Bertha: Hook up requirements to the water supply system and cross connection program

Increases the use and support of city infrastructure. Reduces the risk that poor management of wells will become a pathway for contaminants and the pumping of other wells will impact contaminant movement to the city wells.

11

7.2 Local Government Controls and Programs The following departments or programs within Todd County may be able to assist the city with issues relating to potential contamination sources that 1) have been inventoried or 2) may result from changes in land and water use within the DWSMA:

7.3 State Agency and Federal Agency Support MDH will serve as the contact for enlisting the support of other state agencies on a case-by-case basis regarding technical or regulatory support that may be applied to the management of potential contamination sources. Participation by other state agencies and the federal government is based on legal authority granted to them and resource availability. Furthermore, MDH administers state regulations that affect specific potential sources of contamination and can provide technical assistance to property owners to comply with these regulations. The following table identifies the specific regulatory programs or technical assistance that state and federal agencies may provide to the City of Bertha to support implementation of the WHP plan. It is likely that other opportunities for assistance may be available over the 10-year period that the plan is in effect due to changes in legal authority or increases in funding granted to state and federal agencies. Therefore, the table references opportunities available when the city’s WHP plan was first approved by MDH.

7.4 Support Provided by Nonprofit Organizations

The Minnesota Rural Water Association can provide a wide variety of technical support ranging from helping to develop / update wellhead protection (WHP) plans, locate and secure funding for implementation and provide on-site technical assistance for the implementation of this plan.

Chapter 8 - Goals Goals define the overall purpose for the WHP plan, as well as the end points for implementing objectives and their corresponding actions. The WHP team identified the following goals after considering the impacts that changes in land and water uses may have on drinking water quality over time and future changes that need to be addressed to protect the community’s drinking water:

Maintain and protect the good quality of water produced from the City of Bertha wells and prevent contamination of the aquifer.

Maintain a safe and adequate drinking water supply for community residents to protect their health, and

Insure the security of the water system and minimize disruptions to the system.

13

Chapter 9 - Objectives and Plan of Action Objectives provide the focus for ensuring that the goals of the WHP plan are met and that priority is given to specific actions that support multiple outcomes of plan implementation. Both the objectives and the wellhead protection measures (actions) that support them are based on assessing 1) the data elements (Chapter 2), 2) the potential contaminant source inventory (Chapter 4), 3) the impacts that changes in land and water use present (Chapter 5) and 4) issues, problems, and opportunities referenced to administrative, financial, and technical considerations (Chapter 6). 9.1 Objectives The following objectives have been identified to support the goals of the WHP plan for the City of Bertha:

1. Create awareness and general knowledge about the importance of WHP in the City of Bertha and among Bertha Township residents located in the DWSMA.

2. Manage the Inner Wellhead Management Zone to prevent contamination of the aquifer near the public supply wells.

3. Promote proper well management (Sealing of wells and proper well management practices to landowners with private wells.)

4. Gather additional well and aquifer information as opportunities arise to better understand aquifer characteristics in the Bertha area.

5. Track and report WHP implementation efforts to the City Council and MDH. 6. Participate in WHP Meetings with local resource staff (Todd County SWCD & D, MDH, MRWA)

to keep current on WHP issues and discuss plan implementation activities and efforts identified. 7. Keep the Emergency / Contigency plan up to date to be prepared for a potential disruption of

the water distribution system. 9.2 WHP Measures and Action Plan Based upon the factors, the WHP team has identified WHP measures that will be implemented by the city over the 10-year period that its WHP plan is in effect. The objective that each measure supports is noted as well as the lead party and any cooperators, the anticipated cost for implementing the measure and the year or years in which it will be implemented. The following categories are used to further clarify the focus that each WHP measure provides, in addition to helping organize the measures listed in the action plan:

A. WHP Education B. Well Management C. Spill Prevention and Contigency Planning D. Data Collection E. WHP Planning, Coordination & Reporting

14

9.3 Establishing Priorities WHP measures reflect the administrative, financial, and technical requirements needed to address the risk to water quality or quantity presented by each type of potential contamination source. Not all of these measures can be implemented at the same time, so the WHP team assigned a priority to each. A number of factors must be considered when WHP action items are selected and prioritized (part 4720.5250, subpart 3):

Contamination of the public water supply wells by substances that exceed federal drinking water standards.

Quantifiable levels of contamination resulting from human activity.

The location of potential contaminant sources relative to the wells.

The number of each potential contaminant source identified and the nature of the potential contaminant associated with each source.

The capability of the geologic material to absorb a contaminant.

The effectiveness of existing controls.

The time needed to acquire cooperation from other agencies and cooperators.

The resources needed, i.e., staff, money, time, legal, and technical resources. The City of Bertha assigned priority rank for WHP measures below. The following table lists each measure that will be implemented over the 10-year period that the city’s WHP plan is in effect, including the priority assigned to each measure.

Step. 1: Identify any new high capacity well that is proposed for construction in or within one mile of the DWSMA. Step 2: If a high capacity well is identified: contact MDH Hydrologist to evaluate the effect that proposed pumping may have on the boundaries of the delineated WHP area, and work with MDH Hydrologist, DNR and high capacity well owner to minimize potential impacts that pumping may have on water quantity or quality of the public water supply.

Chapter 10 - Evaluation Program Evaluation is used to support plan implementation and is required under Minnesota Rules, part 4720.5270, prior to amending the city’s WHP plan. Plan evaluation is specified under Measure E-7 and provides the mechanism for determining whether WHP action items are achieving the intended result or whether they need to be modified to address changing administrative, technical, or financial resource conditions within the DWSMA. The city has identified the following procedures that it will use to evaluate the success with implementing its WHP plan:

1. An annual briefing to the city council and WHP Team will provide the basis for documenting whether each action step for that year was implemented.

2. The WHP team will meet annually to assess the status of plan implementation and to identify issues that impact the implementation of action steps throughout the DWSMA;

3. The city will assess the results of each action item that has been taken annually to determine whether the action item has accomplished its purpose or whether modification is needed. Assessment results will be presented in the annual briefing to the city council and WHP Team.

4. The city will prepare a written report every 2. 5 years that documents how it has assessed plan implementation and the action items that were carried out. The reports will be sent to MDH every 2.5 years and also available when MDH holds the first scoping meeting with the city to begin amending the WHP plan.

Chapter 11 - Contingency Strategy The WHP plan includes a contingency strategy that addresses disruption of the water supply caused by either contamination or mechanical failure. The city prepared this strategy using a template provided by MDH and presented in Appendix III of this plan.

22

Chapter 12 - Glossary of Terms Data Element. A specific type of information required by the Minnesota Department of Health to prepare a wellhead protection plan.

Drinking Water Supply Management Area (DWSMA). The surface and subsurface areas surrounding a public water supply well, including the wellhead protection area, that must be managed by the entity identified in the wellhead protection plan. (Minnesota Rules, part 4720.5100, subpart 13). This area is delineated using identifiable landmarks that reflect the scientifically calculated wellhead protection area boundaries as closely as possible.

Emergency Response Area (ERA). The part of the wellhead protection area that is defined by a one-year time of travel within the aquifer that is used by the public water supply well (Minnesota Rules part 4720.5250, subpart 3). It is used to set priorities for managing potential contamination sources within the DWSMA.

Emergency Standby Well. A well that is pumped by a public water supply system only during emergencies, such as when an adequate water supply cannot be achieved because one or more primary or seasonal water supply wells cannot be used.

Inner Wellhead Management Zone (IWMZ). The land that is within 200 feet of a public water supply well (Minnesota Rules, part 4720.5100, subpart 19). The City of Bertha must manage the IWMZ to help protect it from sources of pathogen or chemical contamination that may cause an acute health effect.

Nonpoint Source Contamination. Refers to contamination of the drinking water aquifer that is caused by polluted runoff or pollution sources that cannot be attributed to a specifically defined origin, e.g., runoff from agricultural fields, feedlots, or urban areas.

Point Source Contamination. Refers to contamination of the drinking water aquifer that is attributed to pollution arising from a specifically defined origin, such as discharge from a leaking fuel tank, a solid waste disposal site, or an improperly constructed or sealed well.

Primary Water Supply Well. A well that is regularly pumped by a public water supply system to provide drinking water.

Seasonal Water Supply Well. A well that is only used to provide drinking water during certain times of the year, either when pumping demand cannot be met by the primary water supply well(s) or for a facility, such as a resort, that is closed to the public on a seasonal basis.

Vulnerability. Refers to the likelihood that one or more contaminants of human origin may enter either 1) a water supply well that is used by the City of Bertha or 2) an aquifer that is a source of public drinking water.

WHP Area (WHPA). The surface and subsurface area surrounding a well or well field that supplies a public water system, through which contaminants are likely to move toward and reach the well or well field (Minnesota Statutes, part 103I.005, subdivision 24).

WHP Plan Goal. An overall outcome of implementing the WHP plan, e.g., providing for a safe and adequate drinking water supply.

WHP Measure. A method adopted and implemented by a City of Bertha to prevent contamination of a public water supply, and approved by the Minnesota Department of Health under Minnesota Rules, parts 4720.5110 to 4720.5590.

WHP Plan Objective. A capability needed to achieve one or more WHP goals, e.g., implementing WHP measures to address high priority potential contamination sources within 5 years.

1. Introduction

The Minnesota Department of Health (MDH) amended Part I of the wellhead protection (WHP) plan at the request of the city of Bertha (public water supply identification number 1770001). The work was performed in accordance with the Minnesota Wellhead Protection Rule, parts 4720.5100 to 4720.5590. This report presents the delineation of the wellhead protection area (WHPA), the drinking water supply management area (DWSMA), and the vulnerability assessments for the public water supply wells and DWSMA. Figure 1 shows the boundaries for the WHPA and the DWSMA. The WHPA is defined by a 10-year time of travel. Figure 1 also shows the emergency response area (ERA), which is defined by a 1-year time of travel. Definitions of rule-specific terms that are used are provided in the “Glossary of Terms.” This report also documents the technical information that was required to prepare this portion of the WHP plan in accordance with the Minnesota Wellhead Protection Rule. Additional technical information is available from MDH. The wells included in the WHP plan are listed in Table 2. 2. Assessment of the Data Elements

MDH staff met with representatives of the public water supplier on March 24, 2011, for a scoping meeting that identified the data elements required to amend Part I of the WHP plan. Table 1 presents the assessment of these data elements relative to the present and future implications of planning items that are specified in Minnesota Rules, part 4720.5210.

Groundwater Flow Field Figure 2 - Local Groundwater Flow Field Estimated from Well Records

Defined by using static water level elevations from well records in the CWI database and information contained in the county geologic atlas (Peterson, 2010).

Several buried sand aquifers have been identified in the Bertha area. Most of these sand layers are relatively thin and of a limited extent. The DNR has established a naming convention for primary sand aquifers. The aquifer serving the city wells is named B1 and is a pre-Wisconsinan glacial sand deposit (Peterson, 2010). This sand aquifer lies below the lowest clay-rich till unit of the Browerville formation. Figures 3 and 4 show the distribution of the buried sand units and their stratigraphic relationships with adjacent geologic materials. They were prepared using well record data contained in the CWI database. The geological maps and studies that were used to further define local hydrogeologic conditions are provided in the “Selected References” section of this report. 4. Delineation of the Wellhead Protection Area

4.1 Delineation Criteria

The boundaries of the WHPA for the public water supplier are shown in Figure 1. Table 4 describes how the delineation criteria that are specified under Minnesota Rules, part 4720.5510, were addressed.

Table 4 - Description of WHPA Delineation Criteria

Criterion Descriptor How the Criterion was Addressed

Flow Boundary Hydrologic Boundaries

There are no hydrologic flow boundaries close enough to the public water supply wells to have an impact on their capture areas.

Flow Boundary Geologic

Boundaries - See Figure 3

The aquifer serving the city wells was represented as a single, confined homogeneous sand layer enclosed by lower permeability clay-rich till layers. The boundaries of the aquifer serving the city wells were mapped using information from the records of existing wells and interpreted from information contained in the county geologic atlas (Setterholm, 2007; Peterson, 2010).

Flow Boundary Other High-

Capacity Wells

No other high-capacity wells were included in the model. In the original Part I Plan, the impact of pumping at a nearby creamery well was simulated and incorporated into the delineation approach. However, ownership of the creamery facility has changed and the creamery well has not been used since 2007. Therefore, the creamery well was not included.

Daily Volume of Water Pumped

See Table 5 Pumping information was obtained from the city and DNR Appropriations Permit PA 1975-3265. This was converted to a daily volume pumped by a well.

Groundwater Flow Field See Figure 2 The model calibration process addressed the relationship between the calculated versus observed groundwater flow field.

Aquifer Transmissivity

See Table 3

The previous aquifer test plan was approved on May 18, 2011; T was determined from Theis analysis of the drawdown and recovery data from a 24-hour aquifer test conducted by MDH. Uncertainty regarding aquifer transmissivity was addressed as described in Section 4.4.

Time of Travel 10 years The public water supplier selected a 10-year time of travel.

Previous pumping values have been reported to the DNR, as required by the city’s Groundwater Appropriation Permit PA 1975-3265. This information was used to identify the maximum volume of water pumped annually by each well over the previous five-year period, as shown in Table 5. The estimated future pumping amounts for the next five years were provided by the city’s engineer (Moore Engineering, Inc.) and are also shown in Table 5. The maximum daily volume of discharge used as an input parameter in the model was calculated by dividing the greatest annual pumping volume by 365 days. For comparison purposes, the pumping rates used in the 2000 delineation are also provided in Table 5.

The WHPA for this amendment was determined using a combination of two methods, consisting of 1) the Wellhead Protection Area Code (WHPA Code), Version 2.0, developed by the U.S. Environmental Protection Agency (EPA) to provide a basic means for delineating WHPAs (EPA, 1991); and 2) the analytical groundwater flow method named ONEKA (Barnes and Soule, 2003). The resulting WHPA boundaries are a composite of the capture zones calculated using these two approaches (Figure 1). The input files for both models are available at MDH upon request. The WHPA Code is a semi-quantitative method for estimating capture zones for wells that produces a conservative estimate of capture zones because aquifer recharge is not used as an input parameter. It is appropriate to use the WHPA Code for this delineation because no flow boundaries are known to exist in the upgradient direction of groundwater flow from the wells, at least in the areas defined by a one-year and ten-year time of travel. However, it has limited capabilities to address aquifer settings that exhibit variable geologic conditions or variations in the direction of the groundwater flow field. A second code, using the analytical groundwater flow method named ONEKA (Barnes and Soule, 2003), was used to assess the probability of impacts that local variations in hydrogeologic conditions may have on a well capture zone. This model treats aquifer properties and the available water level measurements as variable input parameters. The locations of wells, water levels, and the aquifer geometry were evaluated using information from the CWI database. For the solution, ONEKA finds the flow field that best fits the network of water level elevations by varying the values of the aquifer thickness and transmissivity. ONEKA then evaluates the probability of the capture of a given point based on the number of times it is included in the capture areas generated by the total number of solutions. The output from the model is a capture zone probability map for the specified time of travel (10 years). 4.3 Results of Model Calibration and Sensitivity Analysis

Model calibration is a procedure that compares the results of a model based on estimated input values to measured or known values. This procedure can be used to define model validity over a range of input values, or it helps determine the level of confidence with which model results may be used. As a matter of practice, groundwater flow models are usually calibrated using water elevation or flux.

7

There is nothing to calibrate for the WHPA Code delineation because it is based on calculating flowpath lines using equations that reflect 1) a constant pumping rate, 2) direction of groundwater flow, 3) hydraulic gradient, 4) aquifer thickness, 5) aquifer permeability, and 6) aquifer porosity. As such, it is a simple calculation of the portion of the aquifer that contributes water, based on the width of the flow field that is affected by pumping. The ONEKA Model is used to support the WHPA Code results by using an iterative process which provides the best fit for the ranges of values assigned to its input parameters. This helps to define the subset of values for which the delineation results are most likely to reflect local hydrogeologic conditions and, therefore, provide the best calibration results. Model sensitivity is the amount of change in model results caused by the variation of a particular input parameter. Because of the simplicity of the WHPA model, the direction and extent of the modeled capture zone may be very sensitive to any of the input parameters:

The pumping rate directly affects the volume of the aquifer that contributes water to the well. An increase in pumping rate leads to an equivalent increase in the volume of aquifer within the capture zone, proportional to the porosity of the aquifer materials. However, the pumping rate is based on the results presented in Table 5 and, therefore, is not a variable factor that will influence the delineation of the WHPA.

The direction of groundwater flow determines the orientation of the capture area. Variations in the direction of groundwater flow will not affect the size of the capture zone but are important for defining the areas that are the source of water to the well. The ambient groundwater flow field that is defined in Figure 2 provides the basis for determining the extent to which each model run reflects the conceptual understanding of the orientation of the capture area for a well.

A hydraulic gradient of zero produces a circular capture zone, centered on the well. As the hydraulic gradient increases, the capture zone changes into an elliptical shape, with the well centered on the down-gradient focal point. The hydraulic gradient was determined by using water level elevations that were taken from wells that have verified locations (Figure 2). Generally, the accuracy of the hydraulic gradient determination is directly proportional to the amount of available data that describes the distribution of hydraulic head in the aquifer.

The aquifer thickness, permeability, and porosity influence the size and shape of the capture zone. A decrease in either thickness or porosity causes a linear, proportional increase in the areal extent of the capture zone; whereas permeability defines the relative proportions of the capture zone width to length. A decrease in permeability decreases the length of the capture zone and increases the distance to the stagnation point, making the capture zone more circular in shape and centered around the well.

4.4 Addressing Model Uncertainty

Using computer models to simulate groundwater flow necessarily involves representing a complicated natural system in a simplified manner. Local geologic conditions may vary within the capture area of the public water supply wells, but the amount of existing information that is needed to accurately define this degree of variability is often not available for portions of the WHPA. In addition, the current capabilities of groundwater flow models may not be sufficient to represent the natural flow system exactly. However, the results are valid within a range defined by the reasonable variation of input parameters for this delineation setting. WHPA Code - The WHPA Code has limited capabilities to address these kinds of uncertainties, other than by using multiple runs in which the following the six input parameters are varied: 1) constant pumping rate, 2) hydraulic gradient, 3) direction of ambient flow, 4) aquifer thickness, 5) aquifer

8

permeability, and 6) porosity. The uncertainty associated with the WHPA Code results from 1) the model deficiencies mentioned above, 2) the sensitivity of the WHPA model, and 3) the fact that the model cannot be calibrated. The steps employed for this delineation to address model uncertainty were:

1) Pumping Rate - For each well, the maximum historical (2007) pumping rate was used (Minnesota Rules, part 4720.5510, subpart 4).

2) Ambient Flow Field - A composite of capture zones was created from angles of flow that are 10 degrees greater and 10 degrees lesser than the representative angle of ambient flow (Minnesota Rules, part 4720.5510, subpart 5, B2). In addition, capture zones were also calculated using the angle of ambient flow that resulted from the previous model in 2000. The angle of flow simulated by the model used in 2000 had 5 degrees difference from the representative angle calculated from Figure 2. These zones were also included in the final composite area.

3) Probability Analysis - The ONEKA Model was used to estimate capture zone probability. Capture areas were developed for a range of groundwater flow directions, the addition of the proposed irrigation well, and times of travel of one and ten years (Figure 5). As the model code uses constant input values for each run, several runs were required to include all variations in input parameters. Table 6 documents the variables used to address WHPA Code model uncertainty.

ONEKA Model - Uncertainty related to the water levels reported on well records is based on the accuracy of the ground elevation assigned to the well using topographic maps and the transient variability of the water levels in the aquifer over time. Water levels that are probably inaccurate were identified using data from 1) the CWI database, and 2) the county geologic atlas (Peterson, 2010). Only water levels that fit the flow field (Figure 2) were used for the ONEKA analysis.

9

The ONEKA Model helps to address uncertainties related to aquifer parameters as variations of the flow field. A 10-year capture zone probability map (Figure 5) was generated for the public water supply wells; the values used for the ONEKA Model are shown in Table 7. The ONEKA results fit well with the capture zones calculated from the WHPA Code model. The probability map for the public water supply wells shows that uncertainty of the capture zone increases as the distance from the public water supply wells increases, especially beyond the 40% probability zone. This zone was selected for use in comparison with the WHPA Code capture zones and to map the final WHPA boundaries. To address the uncertainty of the WHPA boundaries, the resulting capture zones for each model run were combined to create a composite WHPA. Figure 5 illustrates the 10-year capture zones delineated using the results from modeling with the WHPA Code and Oneka for the Bertha wells.

5. Delineation of the Drinking Water Supply Management Area

Figure 1 shows the boundaries of the Drinking Water Supply Management Area (DWSMA) and were defined by the public water supplier using the following features:

Highways, streets, roads, or railroad rights-of-ways;

Public Land Survey coordinates; and

Property parcel boundaries (Todd County, 2010).

Updated parcel information provided by Todd County was very useful in delineating the DWSMA boundaries. 6. Summary of Comparisons Between Previous (2000) and Current WHPA

and DWSMA Delineations

A comparison between the old and new DWSMA is shown in Figure 6. Overall, the new DWSMA is smaller in size compared to the previous delineation. This is primarily due to the elimination of the creamery well in the modeling approach used for this plan amendment. Ownership of the creamery changed a few years ago and the facility is no longer in use. DNR water appropriations records also indicate that the creamery well has not been used since 2007. Therefore, the pumping affects of the creamery well were not considered when determining the boundaries of the current WHPA. Two analytic groundwater flow models called 1) Split, Version 2 (Jankovic, 2000) and 2) HUGO (Barnes and Soule, 2001) were used to determine the WHPA boundaries for the original WHP plan (2000). For this plan amendment, different analytic model codes called 1) WHPA Code (EPA, 1991), and 2) ONEKA (Barnes and Soule, 2003) were used. These flow models are very similar to the codes previously used; subsequently, the resulting WHPA boundaries are also very similar. In addition, the discharge rates for the Bertha public wells were adjusted (relative to the original WHP plan) to reflect current and projected pumping conditions (Table 5).

10

The DWSMA was modified to reflect the new WHPA. The northeast portion of the existing DWSMA was eliminated due to the exclusion of the creamery well. The west boundary of the DWSMA was extended several hundred feet because a small portion of the composite capture zone area extended beyond the previous DWSMA boundary. 7. Vulnerability Assessments

The Part I wellhead protection plan includes the vulnerability assessments for the public water supply wells and DWSMA. These vulnerability assessments are used to help select appropriate measures for reducing the potential contaminant source threat to the public water supply. 7.1 Assessment of Well Vulnerability

The vulnerability assessment for each well used by the public water supplier is listed in Table 2 and is based upon the following conditions:

1) The geologic sensitivity of the aquifer at the well sites is considered moderate because of the lack of at least 10 feet of clay-rich geologic materials over the aquifer. However, the driller’s log for Well 3 (603142) indicates the presence of at least 120 feet of sandy clay materials, which provides a significant degree of natural protection to the aquifer from land use activities occurring at the land surface.

2) Isotopic (2000) and water chemistry data from Bertha Well 2 (240649) indicates that the aquifer water has no detectable levels of tritium or human caused contamination. Both of the city wells were sampled for tritium in March 2011 to confirm the vulnerability assessment; however, the results are not yet available from the laboratory.

3) Water samples were collected (March 24, 2011) from the wells and analyzed for chloride and bromide so that chloride/bromide ratios could be calculated and assessed. The chloride/bromide ratio results for Well 2 (240649) indicate that there has been no discernible impact on the aquifer by human activities occurring on the land surface. The chloride/bromide ratio for Well 3 (603142) could not be calculated because there were no detectable levels of bromide (the laboratory reporting limit for bromide is 0.0050 mg/l). However, the low level of chloride (1.97 mg/l) measured also indicates little or no impact to the aquifer by human activities occurring on the land surface.

7.2 Assessment of Drinking Water Supply Management Area Vulnerability

The vulnerability of the aquifer used by the city of Bertha has been determined to be low within the boundaries of the DWSMA. This assessment was based on the following:

1) Isotopic and water chemistry data from wells located within the DWSMA, and the same aquifer, indicate that there are no detectable levels of tritium or human-caused contamination. This assessment will be re-evaluated when the tritium results are available for recent sampling at Bertha Wells 2 and 3 (240649 and 603142).

2) Review of the geologic logs contained in the CWI database and geological maps and reports indicate that the aquifer exhibits a range of very low to moderate geologic sensitivity throughout the DWSMA. The pollution sensitivity map published by the DNR (Peterson, 2010) has determined the aquifer to have a very low sensitivity to pollution.

A. Purpose

The purpose of this Contingency Plan is to establish, provide, and keep updated certain emergency response procedures and information for the City of Bertha, MN which may become vital in the event of a partial or total loss of public water supply services.

B. Public Water Supply Characteristics

1. Current supply source:

City of Bertha Well

Number 2 Well

Number 3

Unique Well # 240649 603142

Supply Source Sand Aquifer Sand Aquifer

Well Depth (ft.) 153’ 160’

Well Diameter (in.) 12” 8”

Well Capacity (gpm) 400 200

Well Production (gpm) 300 205

2. Treatment

The raw water is treated with chlorine and fluoride. In 2012 a new water treatment plant is to be built that will also add polyphosphate to sequester iron and manganese.

3. Storage and distribution The City of Bertha currently has one elevated storage tank with a capacity of approximately 56,000 gallons. The existing elevated storage tank and structure is old and will be replaced in 2012. Presently, the water distribution system serves 225 connections. Presently, the water distribution system is not entirely looped, but plans are to loop much of the system and eliminate dead ends as part of the water distribution upgrade project in 2012. City utility staff flush the system two or more times each year.

4. Maps/plans

The City of Bertha has current up to date maps of the water distribution system prepared and on file with Moore Engineering. Copies of the maps are stored at: City Hall, City Maintenance Shed and available through the city engineer.

Triggers for Implementing Water Supply Reduction/Allocation Procedures:

In the event of a major system disruption, failure, or an emergency, conservation procedures would be enacted by the Public Works Director, City Administrator, Mayor and City Council.

D. Alternative Water Supply Options

1. Surface water sources and treatment needs. There are no rivers near the City of

Bertha that could readily be used as a surface water source. However, the MN National Guard has the ability to provide the emergency treatment of surface waters for human consumption. (The MN National Guard has the ability to provide Reverse Osmosis Water Purification Units capable of supplying 1500 gph or 25 gpm of potable water.) In the event of a major disruption, the City of Bertha may request water purification equipment or tanks to haul up to 2,000 gallons of water from another city water supply to a distribution point or facility in an emergency for the City of Bertha. The following procedure is recommended for contacting the MN National Guard:

1. Contact the Todd County Sheriff (800) 794-5733 or 911 to request assistance from the MN National Guard.

2. Sheriff contacts the MN National Guard; Division of Emergency Management, State Duty Officer (800) 422-0798; and Community Support Group at (651) 282-4013 to request assistance needed for the city.

2. Bottled water supplies, delivery and distribution: The City of Bertha has identified

the following locations where they can obtain bottled water:

1. Wal Mart, Wadena, MN (218) 631-1068 2. Culligan, Wadena MN (218) 631-1579 3. Seven Oaks Express, Bertha, MN (218) 924-3302

3. System interconnects with other water supplies. Not applicable

4. New well. No other new wells are planned at this time. However, in the event that a city well goes down permanently from an emergency, the City of Bertha will contact the MDH District Engineer (320) 223-7339 to initiate procedures for constructing a replacement water supply well under emergency circumstances.

4

5. Emergency or backup wells: The City of Bertha does not have a designated emergency back-up well. However, the city operates 2 primary wells either of which could be operated separately to supply water in an emergency.

6. Emergency treatment of water system. The City of Bertha is in the process of purchasing a generator capable of supplying power to the water treatment plant and city wells. This is to be completed when the Bertha Authority Improvement Project is completed. In the event there are contaminants in the water the city’s treatment plant cannot address, treatment options will be discussed with the MDH District Engineer.

7. Source management (blending). The City presenting alternates pumping and blends water from the 2 municipal wells.

8. Other. No other alternatives have been identified by the city at this time.

E. Inventory of Available Emergency Equipment and Materials

Table E1 contains a list of services, equipment, and supplies that are available to the City of (system) to respond to a disruption in the water system. It is believed that the items contained in Table E1 would be adequate to respond to most (if not all) water system emergencies.

H. Mitigation and Conservation Plan

1. Mitigation

a) Infrastructure maintenance/upgrades/maps: The system is flushed 2 times a year. New water mains are being installed in 2012. Current water infrastructure maps are available at city hall and through Moore Engineering.

b) Regular inspection of tower, well, pump house: All of these items are inspected daily. The well house and chemical rooms have keyed entries and are locked. The water tower is cleaned by McGuire Iron every 5 years.

c) Staff emergency training: Staff receive annual training through the MN Rural Water Association.

d) System security analysis: The city has assessed the likelihood that vandalism may disrupt the water supply and has determined that this can best be avoided by locking all facilities and have keyed entries to buildings. Also, the sheriff department periodically drives by the water supply facilities.

e) Site new backup well: No back up well is planned at this time.

f) System valving to isolate problems: The water system is adequately valved to isolate problems.

9

g) Sanitation procedures for construction/repairs: The city has established

disinfection protocols identified by MDH that must be followed after repair or installation work has been performed on the water system and mains. The city has also enacted a cross control program to help reduce the possibility that contamination may be introduced into the water supply system.

h) Other: All connections are metered which allows for monitoring of water use except a few of the city buildings and churches.

2. Conservation

a) Water meters: All connections are metered and read quarterly by city staff.

b) Public education: The City of Bertha provides their Consumer Confidence Report

annually to water users. Water use conservation tips are occasionally included in the City Newsletter which is placed at area businesses. Water conservation is presented as part of tours of the water treatment plant when high school students visit. Also, the fourth grade class once a year do a coloring contest presented by MN Rural Water Association concerning water conservation as a topic for water week.

c) Rate structure: The City of Bertha reviews water rates on an annual basis. The city

charges a base rate of $18.50 for the first 3,000 gallons, then $1.15 per subsequent 1,000 gallons on a quarterly billing.
