Arsenic in Groundwater - The Unknown Threat

Public wells in the United States are regularly tested for arsenic, but private wells typically are not. However, when arsenic was found in 47% of wells tested in Iowa in 2008, a case study was designed to determine the source. This pilot study in Cerro Gordo County tests 29 parameters of wells and maps them against their depth and source aquifers. See which factors are associated with arsenic contamination in groundwater, recommendations for avoiding contamination, and how researchers, public health officials, and private wells drillers built a successful team to serve the homeowners for this serious threat.
