Lake Hartwell is a large reservoir that supports recreational activities and provides habitat for fish and wildlife. The Savannah River flows to the Atlantic Ocean, and the watershed is ecologically sensitive due to its role in regional water supply and biodiversity. Nutrient loading from wastewater can impact downstream water quality, making treatment standards important for protecting the aquatic ecosystem.
