Off-Site Water Quality or On-Site Productivityby Waldon R. Kerns, Virginia Polytechnic Inst &, State Univ, Blacksburg, VA, USA,
Abstract: Nonpoint sources of pollution are being recognized as the primary source of water quality degradation in many coastal areas. In those areas where management programs are being implemented, the effectiveness criterion is often based upon on-site productivity rather than efficiency in management of water quality for use-related activities. Effective programs must utilize site-specific water-use impact analysis as well as on-site productivity analysis to determine most efficient levels of nonpoint control. This paper provides some perspective on those issues and presents results of an evaluation of alternative public policies for a site-specific nonpoint project in the Chesapeake Bay.
