Distribution System White Papers

Return to Distributions Systems Home Page

EPA worked with stakeholders to develop a series of "white papers" on distribution system issues that serve as background material for EPA, expert and stakeholder discussions.

Two white papers, The Potential for Health Risks from Intrusion of Contaminants into the Distribution System from Pressure Transients, and Deteriorating Buried Infrastructure Management Challenges and Strategies, were prepared by the American Water Works Service Company. 

Five white papers, Permeation and Leaching, Nitrification, Finished Water Storage Facilities, Effects of Water Age on Distribution System Water Quality, New or Repaired Water Mains, were prepared by the American Water Works Association.

These papers present available information and do not represent agency policy or necessarily reflect the views of EPA.
