Matrix New World Engineering, Inc. (Matrix), on behalf of Crane Co., has prepared this Construction
Completion Report for the Augmentation of Subunit A Plume Containment in the North Central Area
(Report) to document construction activities associated with the EA-08 Groundwater Treatment System
(EA-08 GTS), located at 3112 North Litchfield Road, Goodyear Arizona (Site [Figure 1]). The EA-08
GTS included the drilling and installation of one groundwater extraction well (EA-08), the drilling and
installation of one piezometer well (PZ-15) and the construction of one interim liquid granular activated
carbon (LGAC) groundwater treatment system (Figure 2) as part of the overall approach to contain the
northwest portion of the Subunit A plume of trichloroethene (TCE) in the northern plume. All activities
summarized herein were conducted in general accordance with the Work Plan for Augmentation of
Subunit A Plume Containment in the North Central Area dated February 28, 2011 (Matrix 2011a [Work
Plan]) that was approved by the United States Environmental Protection Agency (USEPA) on March
31, 2011. An Addendum – Work Plan for Augmentation of Subunit A Plume Containment in the North
Central Area (Matrix 2011b [Work Plan Addendum]), was submitted to the USEPA on May 13, 2011 to
document alternative pad construction techniques that deviated from the EA-08 concrete pad and
secondary containment construction methods outlined in the approved Work Plan.
The EA-08 GTS was installed based on technical evaluation of available monitoring data from monitor
wells EPA MW-38A and EPA MW-50A, which indicate TCE concentrations that exceed the Federal
Maximum Contaminant Level (MCL) of 5 micrograms per liter (μg/L), and the lack of hydraulic capture
between extraction wells 33A and EA-06 identified in the Draft Subunit A Capture Zone Report (AMEC
2011). The objectives, rationale, and design concepts for extraction well EA-08 were anticipated to
provide the following:
Complete capture of the Subunit A TCE plume in the north central area, Reduce TCE concentrations in monitor well EPA MW-50A, and Provide an interim/temporary treatment system for rapid construction and implementation.
All interim treatment system concepts and designs were also reviewed with USEPA and stakeholder
personnel during a conference call held on September 30, 2010 and at the quarterly technical meeting
Drilling and installation of extraction well EA-08 was conducted by Yellow Jacket Drilling (YJD) (ADWR
License Number 78) from April 11 through June 21, 2011 using a Foremost DR24 HD Dual Rotary drill
rig. Prior to mobilization, the well was permitted through the ADWR by filing a NOI to Drill permit
(Section 3.1). The ADWR assigned well registration number for the EA-08 well is 55-913204. EA-08
well installation and construction activities are summarized in the following sections. A well
construction photo log, including photographs of well drilling, installation, and testing is presented in
Appendix H.
The general chronology of the drilling and well construction is presented below:
April 11, 2011 – Drill Rig mobilization April 14, 2011 – Drilling began May 26, 2011 – Reached a total depth tagged at 229.75 feet bgs and began well construction May 27, 2011 – Annular material placement began June 17, 2011 – Well Construction Complete June 20, 2011 – Initial swab and airlift well development June 21, 2011 – Drill Rig demobilization
4.1 Pre-Field Activities
Prior to initiating field activities, the following pre-field activities were performed:
Submitted a Notification of Initiation of Fieldwork to the USEPA 15 days prior to the initiation of field activities;
Obtained the necessary permits from the ADWR and procured right-of-access agreements from the COG (Section 3.1);
Obtained traffic control permits for side walk closure and utility permits from COG (Section 3.6);
Contacted Arizona Blue Stake to clear the proposed extraction well EA-08 location for public
utilities (Section 3.5); and
Distributed the COG approved resident advisory notice to the residents of the neighborhood where field activities were to be performed.
4.2 Borehole Drilling and Soil Sampling
A 24-inch diameter borehole was drilled using dual rotary drilling methodologies from April 14 through
May 26, 2011 to a total depth of 229.75 feet bgs. Soil lithologic logging activities were performed by a
Matrix field geologist under the supervision of an Arizona licensed Registered Geologist. Lithology was
assessed from the drill cuttings and logged using the United Soil Classification System (USCS) as
described in American Society for Testing and Materials (ASTM) International Standard D 2488-09a
2-inch diameter LCS blank riser pipe from 0 feet bgs to 158.7 feet bgs, 2-inch diameter dielectric coupler from 158.7 feet bgs to 160.03 feet bgs, and 2-inch diameter stainless steel wire-wrap screen (0.030-inch slot) from 160.03 feet bgs to 200 feet
bgs.
The well and sounding tube were constructed by welding together sections of the LCS casing, the
dielectric coupler, and stainless steel screen while hanging the casing string in the borehole. On the
well, centralizers were welded at approximately 40-foot intervals. After all sections were welded, the
casing remained hanging five feet off of the bottom of the borehole until the annular materials were
added.
Once the well casing and sounding tube were installed to the depths listed above, emplacement of
annular materials began on May 27, 2011 using a Tremie pipe. The calculated values for the annular
materials were checked against actual soundings within the annulus during emplacement to determine
the geometry of the pipe. Chlorine powder was added periodically during gravel pack emplacement as
a disinfectant. The well screen was swabbed periodically during placement of the gravel pack to settle
the gravel pack around the well screen and reduce the potential for bridging. A copy of annular
material records can be found in Appendix L. A summary of annular material construction from top to
bottom is as follows:
Grout was placed from 0 feet to 114.5 feet bgs, An upper bentonite seal was placed from 114.5 feet bgs to 125 feet bgs, An 8x12 Colorado silica sand filter pack was placed from 125 feet bgs to 212.06 feet bgs, and A lower bentonite seal was placed from 212.06 feet bgs to 229.75 feet bgs.
4.4 Well Development
Upon completion of the well on June 17, 2011, including placement of all annular materials, the well
was initially developed by YJD by swabbing and airlifting using a 10-foot double-flanged perforated
swabbing tool. Prior to the initial development, Aquaclear phosphate free detergent (PFD) was added
to the well to help breakdown the drilling fluid and borehole wall cake. Frac tanks were used to
separate the solids from the water prior to treatment using a temporary LGAC unit and discharge to the
RID Canal. Swabbing and airlifting was conducted in 10-foot sections within the screen interval of the
well. Water parameters (pH, temperature, and conductivity) were collected at appropriate intervals
during airlifting to monitor the progress of development. On June 21, 2011, once swabbing and
airlifting was complete, the drill rig and equipment were demobilized from the Site.
5.0 INTERIM GROUNDWATER TREATMENT SYSTEM CONSTRUCTION ACTIVITIES
Construction of the EA-08 GTS was initiated on August 15, 2011, and system startup occurred on
December 7, 2011. The EA-08 GTS is located at 3112 North Litchfield Road, Goodyear Arizona, along
the RID Canal, within the COG Right-of-Way, adjacent to and just east of the EA-08 well (Figure 2).
The EA-08 GTS was constructed to remove VOCs, targeting TCE, from the EA-08 north central Subunit
A groundwater capture zone.
Extracted groundwater from EA-08 is treated at the EA-08 GTS compound using a Hayward Maxiline
mulit-bag filter for pretreatment and an LGAC system for VOC treatment. The LGAC System is
comprised of two 10,000-lb vessels connected in a lead/lag configuration. Treated effluent from the
EA-08 GTS is discharged to the RID Canal in accordance with the RID access agreement (Section
3.3). Details on the EA-08 GTS are provided in the subsections below.
5.1 Process Description
The process description for the EA-08 extraction and treatment system is as follows:
A 40-horsepower (Hp) submersible groundwater pump was sized and installed to extract up to 400 gpm of contaminated groundwater through the EA-08 GTS.
Groundwater is pre-filtered to remove particulate matter by a six bag multi-bag filter housing. The
filters are sized to remove particulate matter greater than 10 microns. Groundwater is then pumped through two 10,000-lb LGAC treatment vessels arranged in a series
treatment format. Following treatment, the treated groundwater is discharged to the RID Canal via temporary 6-inch
ductile iron pipe (DIP) below ground and 6-inch Sch 80 PVC above ground. At the actual discharge into the RID Canal, the exposed piping is also 6-inch DIP per RID requirements.
As-built figures are provided in Appendix P to illustrate the design and final construction of the EA-08
GTS. These include a Process and Instrumentation Diagram (P&ID), Facility Plan and Profile, and
Facility Profile and Details, including the RID outfall design (Appendix P). In addition, vendor supplied
information for the major process equipment has been provided in Appendices Q through X. As
integrated, these items result in a system that is capable of meeting the performance and design
specifications the USEPA approved in the EA-08 Work Plan and Work Plan Addendum. Additional
The Hayward bag filter housing utilizes six bag filters and is designed to handle a maximum flow rate of
900 gpm.
Based on Site experience, filtration to 10 microns was utilized at the EA-08 GTS to remove particulates
before the LGAC vessels. The bag filter housing was mounted to a ¼-inch steel plate to distribute the
loading within the system containment area. The bag filters in the housing are replaced when the
differential pressure across the filter housing increases to approximately 10 to 14 pounds per square
inch (psi). The system control logic to shut down the system at a high differential pressure is field
adjustable and is currently set at 15 psi similar to other PGA-North GTSs. In the event a high
differential pressure condition is realized by the programmable logic control (PLC), an alarm will be
triggered, shutting down the GTS, and the operators will be notified of the alarm condition. The
Hayward multi bag filter vessel information is provided in Appendix S.
5.2.3 System Tie-ins and Piping
The EA-08 GTS includes the following influent and effluent connections:
6-inch Sch 80 PVC pipe and fittings from the wellhead to the bag filter housing, the bag filter housing by-pass, and to the influent connection on the carbon adsorber manifold, and from the effluent connection on the adsorber manifold to the RID discharge line.
The Sch 80 PVC transitions to Class 53 DIP and fittings, per RID requirements, immediately
outside of the EA-08 GTS compound. The transition was completed using a 6-inch Sch 80 PVC van stone flange mated to a 6-inch DIP flange adapter. The above ground discharge pipe at the RID Canal is also 6-inch DIP.
The DIP fittings and pipe were provided with a factory applied asphaltic material coating.
On the 6-inch influent and effluent pipe to and from the manifold, a Sch 80 PVC tee with a van
stone flange and blind flange mated together were provided. These connections were included to facilitate possible future system augmentation or reconfiguration. These connections were installed as shown in Appendix P.
Crane ductile iron butterfly valves, installed to control flow and isolate process equipment for
maintenance purposes, were installed in the Sch 80 PVC process piping (using van stone flanges to connect in line), and also included in the Crane Co. carbon adsorber manifold.
A 6-inch flow meter is installed after the multi-bag filter unit but before the LGAC vessels to
provide real time flow rate and totalized flow information to the operator. The flow meter is a Badger Meter M2000. The Badger Flow Meter Manual is included in Appendix T.
The instrumentation and controls for the EA-08 GTS were integrated into a process control system
similar to those in use at the EA-05 GTS and EA-06 GTS. The process control system was developed
by Presidio Systems, Inc. The Presidio Systems schematic drawings for the process control system
are provided in Appendix U. A PLC was installed with inputs and outputs to accommodate
communication and control of key components of the EA-08 GTS. The inputs that are monitored by the
PLC are the decision logic process parameters (i.e. system flow rates and pressures) that are used to
determine and control the operation of the entire treatment system. The outputs are used to control
specific process parameters (e.g., flow rate by controlling the groundwater extraction pump's variable
frequency drive [VFD]), record operational data, and allow the system to be monitored remotely.
The following instrumentation and controls are in use by the EA-08 GTS:
A Badger direct read magnetic flow meter model M2000 (Appendix T) with a signal output to the PLC is located after the multi-bag filter unit but before the LGAC vessels as shown in Appendix P. This flow meter is of a similar type and manufacture as those used on the EA-05 GTS and EA-06 GTS; and
Pressure gauges and a Barksdale Model No. 425N1-05-P2 pressure transmitter with a signal output to communicate with the PLC was installed to monitor system pressures throughout the process, including differential pressure across the multi-bag filter unit and both LGAC vessels. Pressure gauges and transmitters are located at the influent and effluent of the multi-bag filter unit, the LGAC vessels mid-point on the manifold and the system effluent. Barksdale pressure transmitter information is included in Appendix V.
A Sierra Wireless Raven-X Broadband Cellular Modem (CDMA channel configuration, network using
Verizon Wireless) was installed inside the motor circuit protector (MCP) enclosure. Matrix can access
the trend data (alarms, flow rate, flow totals to date, pressure) remotely through the internet using the
modem, and download the data remotely when necessary. The control panel vendor can also access
the PLC remotely through the modem in the event trouble-shooting is required, or
updates/modifications are required. The PLC provides the data logging capability and trend data for
the 40-Hp submersible well pump run time, logging of influent flow meter instantaneous rate and
totalizing function, alarm conditions, pressure transmitter readings, etc. Information related to the
Sierra Wireless Raven-X Broadband Modem is included in Appendix W
5.2.5 Well Pump
A 6-inch diameter Grundfos Model 475S400-5B, 40-Hp, electric, submersible, stainless steel pump is
installed in well EA-08 to extract groundwater. The pump is equipped with a PVC shroud to force
extracted water around the pump motor and promote cooling. The pump intake was installed to
according to the procedures outlined in the existing EA-05 Groundwater Treatment System Operations
and Maintenance Plan (Matrix 2011c).
5.4 EA-08 System Operation and Maintenance
It is anticipated that the O&M activities required to operate the proposed LGAC system will be similar to
the existing O&M activities performed at the EA-05 treatment system as outlined in the existing EA-05
Groundwater Treatment System Operations and Maintenance Plan. Minor changes to the system
design may result in changes to these previously described O&M activities following start-up and
shake-down of the system. It is proposed that the O&M procedures for this new system will be
formalized, following start-up of the system, in a separate document. It is estimated that the draft O&M
plan will be provided to USEPA by third quarter 2012. In summary, the primary activities associated
with O&M of the EA-08 GTS are:
Weekly inspection of the system, documentation of pressure and flow readings for process equipment, flow meters, etc. at the EA-08 GTS;
Monthly compliance sampling of the LGAC system and associated reporting; Change-outs of bag filters on the system influent, prior to discharge of treated groundwater to the
RID Canal, on an as-needed basis; Change-outs of spent carbon as required, and changing the lead/lag configuration of the adsorbers
as needed; Maintenance of the extraction well pump in accordance with manufacturer specific procedures and
guidelines or as needed; and Maintenance and upgrades of all process equipment, instrumentation, valves and piping as needed
and/or in accordance with manufacturer specific procedures and guidelines. Operation and maintenance activities are conducted by Operations and Maintenance Services, LLC
under direction of AMEC and Matrix.
5.5 EA-08 Discharge
Following treatment, the groundwater is discharged to the RID Canal. Effluent piping is routed from the
treatment compound area, below grade, and travels under the RID access road as shown in Appendix
P. As discussed in Section 5.2.3, prior to crossing the RID access road, the Sch 80 PVC transitions to
Class 53 DIP and fittings. The transition was accomplished using a 6-inch Sch 80 PVC van stone
flange mated to a 6-inch DIP flanged 90 degree elbow. The horizontal extension from the elbow out
