| Abstract: | In 2000, a coal slurry impoundment failure in Martin County, Kentucky, caused concerns about contaminants entering municipal water supplies. Water samples taken from impacted and reference area hot water tanks often exceeded US EPA drinking water guidelines. Concentrations of As, Cd, Cr, Cu, Fe, Mn, and Pb had maxima of 119; 51.9; 154; 170,000; 976,000; 8,710; and 12,700 μg/L, respectively. Significantly different metal accumulation between counties indicated this procedure’s utility for assessing long-term municipal water quality. Correlations between metal concentrations were strong and consistent for As, Ba, Cd, Cr, Co, and Fe indicating that some metals accumulate proportionally with others. |
