Although parts of the Conasauga River System are known for excellent water quality, there are significant water pollution problems in certain stream segments. When the state of Georgia or Tennessee takes a water sample that does not comply with statewide water quality criteria, the segment that the sample came from gets placed on the 303 (d) list. This list includes all stream segments in the state that have been identified as "not supporting" or "partially supporting" the state's water quality criteria. Once this designation is placed on a segment, a total maximum daily load (TMDL) must be created. A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still safely meet water quality standards. These documents usually include the percent reduction of the violating pollutant needed to de-list the impaired segment. Once this TMDL is completed, 319 (h) grants (Clean Water Act grant to reduce non-point source pollution) are often awarded to organizations that want to implement best management practices (BMPs) in the area of impaired segments. BMPs are engineering methods that have been determined to be the most effective, practical means of preventing or reducing pollution from non-point sources (e.g. fence cattle out of stream while providing alternative water sources; this can reduce the pathogen load associated with cattle wastes being directly contributed to the river). Obtaining these section 319 (h) grants and implementing BMPs is a primary activity of the Conasauga River Alliance.

Impairments also exist in the Tennessee portion of the Conasauga Watershed, but they are not identified in this document.
