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.
