The 127 citations in this annotated bibliography provide a substantial resource describing recent investigations on the regulation of water quality. The listing, prepared by NAL's Water Quality Information Center, is part of the Quick Bibliography Series of the National Agricultural Library (NAL), intended primarily for communicating current awareness, and not for use as an in-depth exhaustive bibliography on the subject. Citations were entered in the AGRICOLA database between January 1979 and January 1995 and are listed alphabetically by title. The NAL Call Number is provided for each item. The listing results from a computerized search strategy that includes descriptors for resource type (groundwater, surface water, lake or pond), pollution source (fertilizers, pesticides, agriculture, agrichemicals, nonpoint pollution, nutrients, and livestock waste), and legal terms (legal, illegal, law, legislation, standards, guidelines, regulation, hearing, rule, act, or policy).
