GUIDANCE FOR IMPLEMENTING A POINT-OF-USE (POU) OR POINT-OF-ENTRY (POE) TREATMENT STRATEGY FOR COMPLIANCE WITH SDWA
Impact/Purpose:
EPA and drinking water stakeholders will use the above-mentioned documents. For stakeholders, these documents provide guidelines on technical and managerial issues involved in implementing a successful POU or POE treatment program.
Description:
The challenges facing small drinking water systems were a major focus of the 1996 Amendments to the Safe Drinking Water Act (SDWA). One way Congress sought to help systems meet these challenges was by explicitly allowing systems to install point-of-use (POU) and point-of-entry (POE) treatment devices to achieve compliance with the National Primary Drinking Water Regulations (NPDWRs). This document outlines the technical and managerial issues involved in implementing a successful POU or POE treatment strategy. It describes the types of water quality problems that can and cannot be treated with POU and POE devices and offers recommendations on how to select, install, maintain, and monitor this equipment. With careful attention to source water characteristics, federal, State, and local requirements, and public relations, centrally managed POU or POE treatment can offer a practical alternative to central treatment.
