†All samples cooled to <6° C without freezing ‡ Sodium thiosulfate is required only if residual chlorine is detected. *E.coli samples should always be processed as soon as possible and incubated no later than 8 hours from time of collection. When transport conditions necessitate sample incubation after 8 hours from time of collection, the holding time may be extended and samples must be processed as soon as possible and within 30 hours.


B2 Sampling Methods

Sample Containers Disposable plastic sample containers are purchased pre-cleaned from a reputable vendor (i.e. QEC) or reusable HDPE containers are pre-washed according to the appropriate subcontractor laboratory SOP. Containers are checked for residue after each wash, if washed, and results are recorded in the subcontractor logbooks and retained for five years. Sterile plastic bottles (120mL) with a seal-break lid containing a sodium thiosulfate pill are used for Enterococci and E. coli samples. Sterility certifications are maintained by the laboratory per TNI Standards.


B3 Sample Handling and Custody

Sample Tracking Proper sample handling and custody procedures ensure the custody and integrity of samples beginning at the time of sampling and continuing through transport, sample receipt, preparation, and analysis. A sample is in custody if it is in actual physical possession or in a secured area that is restricted to authorized personnel. The Chain of Custody (COC) form is a record that documents the possession of the samples from the time of collection to receipt in the laboratory. The following information concerning the sample is recorded on the COC form (See Appendix E). The following list of items matches the COC form in Appendix E. All COC forms to be used in the project should be included in Appendix E for the TCEQ’s review.

1. Date and time of collection 2. Site identification 3. Sample matrix 4. Number/Type of containers 5. Preservative used 6. Analyses required 7. Name of collector 8. Custody transfer signatures and dates and time of transfer 9. Bill of lading, if applicable

Sample Labeling Samples from the field are labeled on the container, or on a label; with an indelible marker. Label information includes: Site identification Date and time of collection Preservative added, if applicable Sample type (i.e., analyses) to be performed

Sample Handling All samples collected and/or analyzed are logged into the respective LIMS. A unique identifier label is generated and attached to each sample bottle. Appropriate personnel in each lab confirm receipt by signing the appropriate Chain of Custody Form (See Appendix D). The sample login information includes sample ID, project, location, sample type, date and time sampled, date and time of receipt, sample matrix, collector’s name, analyte(s), preservative, and field comments. The laboratory checks samples for the following qualities, where appropriate, to evaluate sample acceptance: temperature, pH, preservative type, bottle type, sample integrity, fully required documentation (see above), and holding times. Samples are then stored in the designated refrigerators until analysis. Holding times are monitored by the appropriate personnel in each laboratory. The LIMS may also issues warnings to the user prior to the expiration dates.


SRA and / or EEL are contacted and a pickup time is determined same-day prior to sampling.

• For EEL, the samples remain in the designated sample refrigerator or field cooler(s) until EEL arrives and the chain of custody form is completed (see Appendix E). EEL then transports the sample to their laboratory for testing.

• For SRA, the samples remain in the designated field cooler(s) until either SRA arrives or the samples can be dropped off at the SRA laboratories, and the chain of custody form is completed (see Appendix E). When appropriate, SRA then transports the sample to their laboratory for testing.

Sample handling procedures by LNVA are also included in the LNVA Laboratory QA Manual, Section 22: Sample Management. Sample handling procedures including Sample Receipt/Tracking, Sample Acceptance, Sample Storage, Chain of Custody, and Sample Disposal are detailed in the EEL QA Manual, Section 4.0: Sample Handling and SRA-TXFY 2018-19 QAPP for the Clean Rivers Program. Samples analyzed by contract laboratories will be included on the appropriate Chain of Custody forms.


B4 Analytical Methods

Analytical Method Deficiencies and Corrective Actions Deficiencies in field and laboratory measurement systems involve, but are not limited to such things as instrument malfunctions, failures in calibration, blank contamination, quality control samples outside QAPP defined limits, etc. If the problem is not resolvable, then it is conveyed to the LNVA Project Manager, who will make the determination and notify the LNVA QAO. The EEL Technical Director and SRA Technical Manager will report unresolvable problems to the LNVA Project Manager. If the analytical system failure may compromise the sample results, the resulting data will not be reported to the TCEQ. The nature and disposition of the problem is reported on the data report which is sent to the LNVA Project Manager. The LNVA Project Manager will include this information in the CAP and submit with the Progress Report which is sent to the TCEQ CRP Project Manager. The definition of and process for handling deficiencies and corrective action are defined in Section C1.


B5 Quality Control Comparison Counting For routine bacteriological samples, repeat counts on one or more positive samples are required, at least monthly. If possible, the analyst should compare counts with another analyst who also routinely performs the analysis. Replicate counts by the same analyst should agree within 5 percent, and those between analysts should agree within 10 percent. Record the results.


B5 Quality Control

Quality Control or Acceptability Requirements Deficiencies and Corrective Actions Sampling QC excursions are evaluated by the LNVA Project Manager, in consultation with the LNVA QAO. In that differences in sample results are used to assess the entire sampling process, including environmental variability, the arbitrary rejection of results based on pre-determined limits is not practical. Therefore, the professional judgment of the LNVA Project Manager and QAO will be relied upon in evaluating results. Rejecting sample results based on wide variability is a possibility. Notations of blank contamination are noted in the quarterly report and the final QC Report. Laboratory measurement quality control failures are evaluated by the respective laboratory staff. The disposition of such failures and the nature and disposition of the problem is reported to the LNVA QAO. The LNVA QAO will discuss with the LNVA Project Manager. If applicable, the respective laboratory Technical Director or Manager will include this information in a CAP and submit to the LNVA Project Manager. The LNVA Project Manager will include this information with the Progress Report which is sent to the TCEQ CRP Project Manager. Additionally, in accordance with CRP requirements and the TNI Standard (Volume 1, Module 2, Section 4.5, Subcontracting of Environmental Tests) when a laboratory that is a signatory of this QAPP finds it necessary and/or advantageous to subcontract analyses, the laboratory that is the signatory on this QAPP must ensure that the subcontracting laboratory is NELAP-accredited (when required) and understands and follows the QA/QC requirements included in this QAPP, including methodology. The signatory laboratory is also responsible for quality assurance of the data prior to delivering it to the Basin Planning Agency, including review of all applicable QC samples related to CRP data. As stated in section 4.5.5 of the TNI Standard, the laboratory performing the subcontracted work shall be indicated in the final report and the signatory laboratory shall make a copy of the subcontractor’s report available to LNVA when requested. The definition of and process for handling deficiencies and corrective action are defined in Section C1.


B10 Data Management

Data Management Process The water quality data generated from field are recorded on field data sheets by the LNVA environmental analysts and entered into the LIMS. All laboratory data received from EEL and SRA is entered into the LIMS. Laboratory quality checks are reviewed by the LNVA QAO. If all QA/QC requirements are acceptable, the data will be exported from the LIMS into the proper CRP database format by the LNVA Data Manager. The Data Review Checklist is completed and the Data Summary is prepared by the LNVA Data Manager and submitted to the LNVA Project Manager. Upon final review and approval by the LNVA Project Manager, the CRP database tables will be submitted to the TCEQ CRP Project Manager in the Events/Results file format specified in the SWQM Data Management Reference Guide. After a review for completeness, the data files are forwarded to the CRP Data Manager for loading into the SWQMIS database. Data Dictionary Terminology and field descriptions are included in the DMRG. A table outlining the entity that will be used when submitting data under this QAPP is included below for the purpose of verifying which entity codes are included in this QAPP.

Name of Entity Tag Prefix Submitting Entity Collecting Entity

Lower Neches Valley Authority M LV LV


B10 Data Management

Data Errors and Loss All field data sheets are reviewed for errors and omissions upon completion by all analysts. A CRP data review checklist is completed for each dataset. In addition, the LIMS software has drop down menus and data ranges established for each parameter to reduce errors. All CRP database files are converted to pipe delimited text files and archived after submission to the TCEQ.


C2 Reports to Management Deficiencies and Corrective Actions In the event that data quality issues are encountered during the data collection or during analysis, the issue will be reported immediately to the LNVA Project Manager by the responsible party.


D2 Verification and Validation Methods All field and laboratory data will be reviewed, verified and validated to ensure they conform to project specifications and meet the conditions of end use as described in Section A7 of this document. Data review, verification, and validation will be performed using self-assessments and peer and management review as appropriate to the project task. The data review tasks to be performed by field and laboratory staff is listed in the first two columns of Table D2.1, respectively. Potential errors are identified by examination of documentation and by manual, examination of corollary or unreasonable data, or computer-assisted. If a question arises or an error is identified, the manager of the task responsible for generating the data is contacted to resolve the issue. Issues which can be corrected are corrected and documented. If an issue cannot be corrected, the task manager will consult with the higher level project management to establish the appropriate course of action, or the data associated with the issue are rejected and not reported to the TCEQ for storage in SWQMIS.

Appendix B: Sampling Process Design and Monitoring Schedule (Plan)

Sample Design Rationale FY 2019 The sample design is based on the legislative intent of CRP. Under the legislation, the Basin Planning Agencies have been tasked with providing data to characterize water quality conditions in support of the Texas Water Quality Integrated Report, and to identify significant long-term water quality trends. Based on Steering Committee input, achievable water quality objectives and priorities and the identification of water quality issues are used to develop work plans which are in accord with available resources. As part of the Steering Committee process, the LNVA coordinates closely with the TCEQ and other participants to ensure a comprehensive water monitoring strategy within the watershed. The following changes have been made to the monitoring schedule. These changes have come about because of concerns or requests of steering committee members or monitoring entities.

1. Site number 15675 on the Bear Creek arm of Sam Rayburn Reservoir has been removed, as site number 15674 is also on the Bear Creek arm and located in the same sampling segment. Sampling data have also indicated strong correlations in all parameters between the two sites.

2. Site number 15670 on the Angelina arm of Sam Rayburn Reservoir has been removed, as site number 15671 is also on the Angelina arm and located in the same sampling segment. Sampling data have also indicate strong correlations in all parameters between the two sites.
