Linking environmental and public health data to evaluate health effects of arsenic exposure from domestic and public supply wells

Everyone needs clean drinking water in order to thrive. The US EPA and public water purveyors in the US work together in adherence with the Safe Drinking Water Act to make water safe for public consumption. The recent media coverage of lead in public drinking water supplies in Flint, Michigan, and schools in many cities with aging infrastructure throughout the US has raised public awareness of drinking water as a potential pathway of exposure to toxic chemicals. Epidemiologists and other researchers have conclusively shown that high arsenic levels in drinking water in Bangladesh, Taiwan, and South America cause adverse human health outcomes. However, research in study populations with levels of arsenic exposure relevant to communities in the US is needed to understand the health risks, if any, contributed by drinking water exposures. This proposed research will determine correlative and other statistical associations between arsenic exposure from domestic and public supply wells and human health outcomes using existing databases and related modeling.
