Partial Abandonment of GroundwaterWells:A Non-Treatment Method to Mitigate for High Arsenic Levels

摘要

Water agencies across the U.S. face a formidable challenge to address high levels ofarsenic encountered in existing groundwater production wells. With recentimplementation of the U.S. Environmental Protection Agency's new maximumcontaminant level of 10 parts per billion for arsenic in drinking water, water agencieshave struggled to identify and implement cost-effective mitigation methods toaddress arsenic. This paper describes a cost-effective, non-treatment method tomitigate for arsenic by partially abandoning existing groundwater wells.
