Decontamination Methods for Wastewater and Stormwater Collection and Treatment Systems

Abstract

Contamination of wastewater or stormwater systems may be one consequence of a terror attack involving chemical, biological, or radioactive agents. Such agents could enter the system through a contaminated water supply, runoff from a contaminated landscape, or effluent from decontamination operations. Once in a wastewater treatment plant, these agents may be removed or inactivated by conventional processes, but treatment residuals and collection system equipment, including piping, tanks, pumps, and related equipment, may themselves require decontamination or special treatment. This article discusses available information, technology, and methods for decontamination of wastewater and stormwater systems following a contaminating event.
