Water Quality


ADEM administers a number of programs related to the State's surface water quality. These programs include:

Water Quality Standards - include both the designated uses of surface waters and the criteria intended to protect those uses. Designated uses are listed in ADEM regulations at 335-6-11 and the criteria are found in 335-6-10.

Water Quality Report to Congress (305(b) Report) - biennial report submitted to the United States Environmental Protection Agency as part of the national water quality assessment required by the Clean Water Act. This report provides a summary of activities related to surface water quality and an assessment of surface water quality conditions in Alabama.

List of Impaired Waters (303(d) List - list of waterbodies in Alabama that do not fully support their designated uses based on a review of water quality data and information. The list is submitted to the United States Environmental Protection Agency for approval after an opportunity for public comment. The list includes the causes and sources of water quality impairment for each waterbody listed and a schedule for development of Total Maximum Daily Loads (TMDLs) for each pollutant causing impairment.

Total Maximum Daily Load (TMDL) Development - for waterbodies included on the 303(d) list the State must determine the amount of each pollutant causing water quality impairment that can be allowed such that the water quality standards for the waterbody are maintained. The TMDLs are developed according to a specified schedule and must be approved by the United States Environmental Protection Agency after an opportunity for public comment.

Waste Load Allocation Development - waste load allocations are developed for proposed and existing dischargers to surface waters in support of National Pollutant Discharge Elimination System (NPDES) permits that are protective of water quality standards.

Water Quality Planning - Section 303(e) of the federal Clean Water Act (CWA) requires that each State establish and maintain a continuing planning process (CPP) consistent with the CWA and pertaining to all navigable waters of the State. The State is responsible for managing its water quality program to implement the processes specified in the CPP. The U.S. Environmental Protection Agency (EPA) is responsible for periodically reviewing the adequacy of the State's CPP. Alabama's CPP is an umbrella document that provides the framework to coordinate and unify the activities and procedures necessary for maintaining waters of an acceptable quality throughout the State, in a manner consistent with the Alabama Water Pollution Control Act and the federal Clean Water Act.

Surface Water Quality Monitoring Strategy

Download ADEM Data from STORET
As Alabama's state environmental regulatory agency, the ADEM submits all surface water quality monitoring data to EPA's STORET (short for STOrage and RETrieval) Data Warehouse. STORET is a repository for water quality, biological, and physical data and is used by state environmental agencies, EPA and other federal agencies, universities, private citizens, and many others. These organizations submit data to the STORET Warehouse to make their data publically accessible.
