A System's Guide to the Management of Radioactive Residuals from Drinking Water Treatment Technologies

This short document provides information on the available treatment technologies for the removal of:

  • Radium,
  • Uranium, and
  • Gross alpha particle activity (radionuclides).

It also includes information on the residuals produced by each technology and disposal options. The document also details the regulations governing these options.

A Regulator's Guide to the Management of Radioactive Residuals from Drinking Water Treatment Technologies

This document assists EPA Regions, states, and PWSs in deciding which treatment technologies systems may use based on:

  • Treatment efficiency,
  • Disposal of residuals containing radionuclides, and
  • Worker safety concerns.

EPA is providing this guidance manual primarily to states and technical assistance providers. They will then provide guidance to those PWSs affected by the Radionuclides Rule.
