Participatory Interventions to Reduce Arsenic Exposure in American Indian Communities

In the US, arsenic in drinking water disproportionately affects rural populations including American Indian (AI) communities. Arsenic is associated with an increased risk of cardiovascular disease, diabetes, kidney disease, and cancer in AIs from Arizona, Oklahoma, and North/South Dakota who participated in the Strong Heart Study (SHS). The SHS has been working with these AI communities for more than 25 years and these findings highlight the urgent need to prevent arsenic exposure in these populations, especially in North and South Dakota, where naturally occurring arsenic in drinking water is frequently above 10 µg/L, the current US Environmental Protection Agency (EPA) safety standard. To address this problem, we are developing and evaluating the effectiveness of multi-level participatory interventions in reducing arsenic exposure among AI communities (Ogala Sioux, Cheyenne and Spirit Lake) from North and South Dakota who participated in the SHS.
