New tracers can identify coal ash contamination in water

Laboratory and field tests confirm that new boron and strontium tracers, developed by researchers at Duke, the Univ. of Arkansas-Little Rock, and the Univ. of Kentucky, can detect the distinctive isotopic and geochemical fingerprints of coal ash contamination in water. The tracers will allow the US Environmental Protection Agency and other regulators to distinguish coal ash contamination from other, similar contamination coming from different sources in a watershed, and trace the coal ash to its source. —> Read More Here
