In 1991, the Texas Legislature
passed the Texas Clean River Act (Senate Bill 818) in response to growing
concerns that water resource issues were not being pursued in an integrated,
systematic manner. The act requires that
ongoing water quality assessments be conducted for each river basin in
The purpose of this QAPP is to clearly delineate SRA QA policy, management structure, and procedures which will be used to implement the QA requirements necessary to verify and validate the surface water quality data collected. The QAPP is reviewed by the TCEQ to help ensure that data generated for the purposes described above are scientifically valid and legally defensible. This process will ensure that data collected under this QAPP and submitted to the statewide database have been collected and managed in a way that guarantees its reliability and therefore can be used in water quality assessments and other programs deemed appropriate by the TCEQ. Project results will be used to support the achievement of Clean Rivers Program objectives as contained in the Clean Rivers Program Guidance and Reference Guide FY 2006 -2007.
The SRA Environmental Services Division (ESD) collects
surface water quality data as part of its commitment to water quality
protection in the
The basin topography has been used to divide the Basin into
110 subwatersheds (24 of these are located in
Water quality data is analyzed using the data analysis program developed by SRA following guidance from the TCEQ. The Routine and Special Study Monitoring programs are reviewed each year to consider revisions in every aspect of the programs.
Monitoring plans
were developed by the SRA and other monitoring partners in cooperation with
TCEQ staff at the annual coordinated monitoring meetings. The SRA will conduct 24-hour dissolved oxygen
monitoring on Indian Creek upstream of the city of

Amendments to the QAPP
Revisions to the QAPP may be necessary to address incorrectly documented information or to reflect changes in project organization, tasks, schedules, objectives, and methods. Requests for amendments will be directed from the SRA Project Manager to the CRP Project Manager electronically. They are effective immediately upon approval by the SRA Project Manager, the SRA QAO, the CRP Project Manager, the CRP Lead QA Specialist, and the CRP Project QA Specialist. They will be incorporated into the QAPP by way of attachment and distributed to personnel on the distribution list by the SRA Project Manager.
Special Project Appendices
Projects requiring QAPP appendices will be planned in consultation with the SRA and the TCEQ Project Manager and TCEQ technical staff. Appendices will be written in an abbreviated format and will reference the Basin QAPP where appropriate. Appendices will be approved by the SRA Project Manager, the SRA QAO, the CRP Project Manager, the CRP Project QA Specialist, the CRP Lead QA Specialist and other TCEQ personnel as appropriate. Copies of approved QAPP’s appendices will be distributed by the SRA to project participants before data collection activities commence.
The purpose of routine water quality monitoring is to collect surface water quality data needed for conducting water quality assessments in accordance with TCEQ’s Guidance for Assessing Texas Surface and Finished Drinking Water Quality Data. These water quality data, and data collected by other organizations (e.g., USGS, TCEQ, etc.), will be subsequently reconciled for use and assessed by the TCEQ.
The purpose for data collected for Special Study monitoring will be addressed in Appendix E.
The measurement performance
specifications to support the project objectives for a minimum data set are
specified in Table A7.1 and in the text following. The SRA laboratory will perform all of the
analyses listed in Table A7.1.
