Abstract: Recent Iowa studies have documented the widespread occurrence of arsenic in private drinking water wells. A 2006-08 survey of 473 wells showed that almost half of the water samples contained arsenic; about 8% of those had arsenic concentrations at or above 10 parts per billion, the EPA drinking water standard for public water supplies. This conference presented overviews of the possible health effects related to drinking water arsenic, Iowa surveillance efforts on arsenic in groundwater, current Iowa-based research on the fate and transport of arsenic in the environment, treatment options for arsenic removal/reduction in small systems, and current water quality education programs in Iowa. Researchers from Minnesota and Wisconsin discussed efforts to address arsenic concerns in those states, and a panel of experts responded to audience questions on what approaches might be taken in Iowa to develop public education programs on arsenic and efforts to prevent or limit arsenic contamination of drinking water supplies. Conference attendees had the opportunity to discuss this emerging public health issue with academic and agency researchers and with policy makers from state government.
