Nez Perce County Demographic Comparison Expect lower concentrations than in other U.S. data.

Potential Concern FormaldehydeAcetaldehyde BenzeneCarbon tetrachloride Tetrachloroethylene1,3-Butadiene ArsenicManganese >50% detects exceed the chronic screening threshold

Chronic Inhalation Cancer Risk Comparison 30-year chronic cancer risk screening values from EPA Region 3 and highest annual mean concentrations from any site in the Lewiston study were used to generate estimated risk numbers.
