  1. Fulltext. The nitrate contamination of private well water in Iowa.

    Article - En anglais


    The State-Wide Rural Well-Water Survey was conducted between April 1988 and June 1989.

    About 18% of Iowa's private, rural drinking-water wells contain nitrate above the recommended health advisory level (levels of NO3-N greater than 10 mg/L); 37% of the wells have levels greater than 3 mg/L, typically considered indicative of anthropogenic pollution.

    Thirty-five percent of well less than 15 m deep exceed the health advisory level, and the mean concentration of nitrate-nitrogen for these wells exceeds 10 mg/L.
