14 III. ENVIRONMENTAL PROBLEMS Environmental problems in the Watershed have been well documented by the Watershed Project and the Alabama Natural Heritage Program. The majority of the water quality problems can be attributed to agriculture, construction, unpaved roads, inadequate or malfunctioning septic tank systems, and increased urban development. Activities that result in a concentrated discharge into surface waters are referred to as “point source discharges” and include discharges from municipal wastewater treatment facilities and industrial sites. There are no point sources that discharge directly into Weeks Bay; however, several point sources discharge into the Fish River and Bay Branch, a tributary to Fish River. The Town of Loxley’s municipal wastewater treatment system (secondary treatment, 3-celled lagoon system,

The GSA, as part of a cooperative project with ADEM initiated water quality sampling in the Weeks Bay Watershed on January 1, 1994. Water sampling continued until January 1999. The purpose of this sampling program was to acquire data for evaluating effects of installing BMPs in the Weeks Bay Watershed for controlling nonpoint source water pollution. Water-analysis data for 20 surface water sites reflect specific water-quality problems relative to standards that apply to fish and wildlife (F&W), a major water use classification for surface waters in the Weeks Bay Watershed. A report prepared by GSA containing the results of the study is available for review at the Weeks Bay Watershed Project office. Weeks Bay Watershed Management Plan
