Best Management Practices for Point and Nonpoint Sources of Groundwater Contaminationby Martin Jaffe, Univ of Illinois at Chicago, Chicago, IL, USA,
Abstract: Management strategies have included regulations to guide or limit development in aquifer recharge areas and in the capture zones of public wellfields, engineering requirements to minimize infiltration into and exfiltration from discrete sources, and administrative innovations which expand or modify agency responsibilities with respect to identified sources posing groundwater threats. The management of nonpoint sources is more problematic. The wide geographic area of application, the relatively low toxicity of many of these contaminants, and the scope of their risks (typically to on-site domestic water supply wells and not to public wells) often make them a lower management priority in many communities. However, a number of communities and state agencies are beginning to examine the incremental impacts of nonpoint sources on groundwater resources and have started to fashion management programs to address these risks. Currently, most nonpoint sources are managed through voluntary compliance and educational programs.
