The 1996 amendments to the Safe Drinking Water Act require that all states develop a source water assessment plan and that source water assessments be prepared for all public drinking water systems within the state. To satisfy these amendments, the Nonpoint Source Section developed the Kansas Source Water Assessment Program Plan (SWAPP). Under the Kansas SWAPP, an assessment of potential sources of pollution that may threaten drinking water sources, within a defined area must be completed. To aid local public water supply systems during the SWAPP process, the Nonpoint Source Section has developed this reference document, which is intended to provide information on potential pollution concerns associated with a given land use or activity. Additionally, the information included is intended to assist in evaluating whether or not a pollution source is being managed adequately. The document also acts as a referral guide to experts in a given environmental field or discipline. These "experts" may be able to provide additional information regarding regulatory status, potential pollutants, proper chemical and/or waste handling, spill prevention, current remedial activities, etc.
