Source Water Assessment Program (SWAP)

The Mississippi Source Water Assessment Program (SWAP) is a result of the Federal Safe Drinking Water Act Amendments of 1996, which mandated all states to identify public water systems that may be susceptible to contamination and to adopt appropriate management measures that will enhance their protection.

Program Plan and Purpose

To assist states in their developmental process and to ensures that the legislative goals of the Safe Drinking Water Act (SDWA) are met, the EPA established a SWAP guidance document, “State Source Water Assessment and Protection Programs Guidance.” This document and three post-guidance clarification documents provided the framework for the Mississippi SWAP plan.

Required Program Elements
  • Public Participation – MS SWAP Chapter II
  • Delineation of Source Water Protection Area – MS SWAP Chapter III
  • Potential Contaminant Source Inventory – MS SWAP Chapter IV
  • Susceptibility Analysis – MS SWAP Chapter V
  • Making Assessments Available to the Public – MS SWAP Chapter VI
  • Program Deadlines – MS SWAP Chapter VII
  • Source Water Protection Program – MS SWAP Chapter VIII
Program Facts
  • There are 1,535 public water supply systems in the state, which are comprised of 3,400 wells and three surface water intakes.
