Evaluating Water Quality

Abstract

The Texas Commission on Environmental Quality (TCEQ) evaluates the condition of the state’s water bodies on a periodic basis under the Clean Water Act (CWA) Section 305(b). The results are contained within the Texas Water Quality Inventory and 303(d) List and are comprised of a complete listing of all water quality concerns in the state. As required by the Act, the inventory is updated every two years and includes the review of the past five years’ data collected by many organizations statewide, including the BRA. The 2006 Water Quality Inventory and 303(d) List, on which the following information is based, provides an assessment of water quality results using the most recent five years of data. This inventory is available on the TCEQ Web site at http://www.tceq.state.tx.us/compliance/monitoring/water/quality/data/wqm/305_3 03.html.
