2002 Texas Water Quality Inventory and 303(d) List

Information on Texas' surface waters, including concerns for public health, fitness for use by aquatic species and other wildlife, and specific pollutants and their possible sources for 2002.

This report describes the status of the state’s waters, as required by Sections 305(b) and 303(d) of the federal Clean Water Act. It summarizes the status of the state’s surface waters, including concerns for public health, fitness for use by aquatic species and other wildlife, and specific pollutants and their possible sources.

Overview

Recent guidance from the U.S. Environmental Protection Agency directs the state to integrate the 305(b) Water Quality Inventory and 303(d) List for all waters of the state.

Section 305(b) of the act requires states to report the extent to which water bodies attain designated standards for water quality.

Section 303(d) of the act requires states to identify water bodies for which effluent limitations are not stringent enough to implement water-quality standards.

Summary: 2002 Texas Water Quality Inventory

This summary of the 2002 Texas Water Quality Inventory describes the status of the state’s waters based on historical water-quality data.

Water-Body Assessments and Categorization

Assessments are based on five years of data on water quality collected by the TCEQ and cooperating agencies under approved quality-assurance guidelines.

Categorization of Water Bodies

One of five categories is assigned to each assessment unit (AU), or area assessed, to provide more information to the public, EPA, and internal agency programs about water-quality management. Water bodies are listed in Categories 1 through 5.
