BEACHNET is an e-mail discussion list that seeks to facilitate communication between people interested in the improvement of recreational beach water quality in the Great Lakes basin. The listserv is sponsored by the Great Lakes Beach Association and hosted by the Great Lakes Information Network (GLIN). Both the Association and discussion list are open to anyone interested in improving recreational beach water quality, understanding bacteria contamination, developing better ways to detect and monitor pollution, or monitoring and assuring beach visitors' health.
