Quality Assurance and Monitoring Procedures for Surface Water Quality Monitoring
TCEQ prepares and maintains documents that guide the collection and management of surface water quality data in Texas.
Quality Assurance Documents
- Quality Assurance for the TCEQ
- TNI's National Environmental
Laboratory Accreditation Management System (LAMS) - a central repository for information about the accreditation status of environmental laboratories - Texas Environmental Laboratory (NELAP) Accreditation
- EPA's Quality System for Environmental Data and Technology
Surface water quality projects involving the generation, acquisition, and use of environmental data are planned through the development of Quality Assurance Project Plans (QAPPs) or other planning documents. These documents are developed by project managers, quality assurance staff, technical staff, management, and contractors using a systematic planning process.
- SWQM Quality Assurance Project Plan (QAPP), Revision 21 (April 2024)
- Quality Assurance Plan (QAP) Shell (April 2024)
- Ambient Water Reporting Limits (AWRLs)
- Continuous Water Quality Monitoring Project Plans
