EPA has developed materials for states and primacy agencies. The materials below can assist in complying with requirements of the Radionuclide Rule.

• Final Implementation Guidance for Radionuclides

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
• 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.

• A Regulator's Guide to the Management of Radioactive Residuals from Drinking Water Treatment Technologies (PDF)(81 pp, 593 K, About PDF) EPA 816-R-05-004, July 2005
• Limits for Beta Particles and Photon Emitters at 4 millrems/year
