Framework for Selecting Corrective Measures for Managing Disinfection Byproducts in Small Drinking Water Systems in Newfoundland and Labrador
纽芬兰和拉布拉多小型饮用水系统消毒副产品管理纠正措施选择框架
Newfoundland and Labrador offer many logistical challenges in trying to provide high quality
drinking water to numerous geographically dispersed small rural communities. 88 percent of
public water supplies in the province service communities of 1500 or less. The problem of
disinfection byproducts (DBPs) in drinking water systems affects approximately one third of
public drinking water systems and up to half the population of Newfoundland and Labrador. The
main DBPs of concern in the province are trihalomethanes (THMs) and haloacetic acids (HAAs).
Any corrective measure implemented must address the issue of DBPs, but must also fit the
community, in terms of available financial, technical, and human resources. An integrated
decision making framework for the management of DBPs was developed based on known DBP
formation behavior and best management practices used to deal with DBPs in other
jurisdictions; assessment of DBP characteristics and response to existing corrective measures in
Newfoundland and Labrador; and, through modeling of water distribution systems. The
developed framework can assist communities and government to figure out how best to deal with
DBP issues. Includes 17 references, tables, figures.
