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

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.

Sample Design Rationale
The sample design is based on the
legislative intent of the Clean Rivers Program. Under the legislation, the Basin
Planning Agencies have been tasked with providing data to characterize water
quality conditions in support of the 305(b) assessment, 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 SRA coordinates closely with the TCEQ and other participants to ensure a
comprehensive water monitoring strategy within the watershed. Past assessments in the
Site Selection Criteria
This data collection effort involves monitoring routine
water quality, using procedures that are consistent with the TCEQ SWQM program,
for the purpose of data entry into the statewide database maintained by the
TCEQ. To this end, some general guidelines
are followed when selecting sampling sites, as basically outlined below, and
discussed thoroughly in the TCEQ Surface Water Quality Monitoring
Procedures, Volume 1 (RG-415).
Overall consideration is given to accessibility and safety. All monitoring activities have been developed
with coordination with the CRP Steering Committee and with the TCEQ.
1.
Routine monitoring
sites are representative of in-stream data and are free from back-water
effects.
2.
Routine monitoring
sites are selected to maximize stream coverage or basin coverage. For very long stretches of river length, a
station is considered representative of a water body for not more than 25 miles
in freshwater and tidal streams. A
single monitoring site is considered representative of 25 percent of the total
reservoir acres and estuary or ocean square miles, but not more than 5,120
acres or 8 square miles.
3.
Routine monitoring
sites are located preferentially where there are “localized” water quality
effects based on past water quality data.
4.
Routine monitoring
sites are located where historical data exists.
No degradation of water quality may be indicated. However, the
continuation of water quality monitoring at this site has been deemed
important.
5.
At least one site for
each classified segment will be selected for routine monitoring unless the
segment is already covered by TCEQ or other qualified monitoring entities
reporting routine data to TCEQ.
6.
Routine monitoring
sites may be selected to bracket sources of pollution, influence of
tributaries, changes in land uses, and hydrological modifications.
7.
Routine monitoring
sites are chosen based on accessibility. When possible, sites are selected
where it is possible to collect flow measurements during routine visits or
where a stream flow gage is located.
Critical vs. non-critical measurements
All data taken for CRP and entered into the SWQM portion of the TRACS database are considered critical.
