PROCEDURES FOR THE DECONTAMINATION OF BUILDING PLUMBING SYSTEMS

摘要

Adequate supplies of clean, safe drinking water are a prerequisite for buildings and their occupants, including both commercial and residential structures and facilities. In the past, there have been occasional concerns regarding insufficient treatment of water supplies or undesirable migration of contaminants from plumbing system materials into water distribution systems, usually due to some change in environmental or operating conditions. More recently, another issue has arisen regarding the potential for accidental or intentional introduction of contaminants into water distribution systems, and the need for effective methods for dealing with such events. This paper describes recommended procedures for responding to building plumbing system contamination incidents and restoring the water system to safe operation. The recommendations are based on analysis of the results of a measurement and modelling research project investigated contamination and decontamination issues related to building plumbing systems.
