The objective of this powerpoint presentation was to evaluate arsenic exposure from NativeAmerican-owned community water systemsand solutions to reduce exposure. The approach included:estimating the number of Native Americansexposed to arsenic through public data review;measuring arsenic concentrations in urinesamples of 54 Walker River Paiute tribalmembers exposed to arsenic via drinkingwater; and,reviewing technical alternatives and policyrecommendations to reduce arsenic exposure. Another CDC Arsenic Exposure Study is presented, Reducing Arsenic Levelsin Drinking Water: Effects on the Body Burden of Arsenic, with the goals of:determining the urinary arsenic concentrations in theWalker River Paiute Tribal community; and,evaluating variations in urinary arsenic concentrations afterconstruction of an arsenic removal treatment plant. A third project is presented of reducing arsenic exposure in Schurz, Nevada. Conclusions:arsenic exposure via communitywater systems is disproportionatelyimpacting Native American Tribes; high arsenic exposure andbiomarker measurements exist forNative Americans exposed toarsenic via their drinking water; and,the solution to reduce long-termexposure needs to be collaborativebut timely. Includes tables, figures.
