Abstract
A study was undertaken to explore whether the isotopic compositions of Pb a nd Sr are useful to distinguish mixtures of uncontaminated groundwater, sea water, and landfill leachate at the Fresh Kills landfill, Staten Island, Ne w York. Ratios of Sr-87/Sr-86 ranged from 0.7088 to 0.7137 and could be use d to distinguish Sr that was derived from seawater from that in uncontamina ted groundwater. Lead isotopic abundances did not vary systematically among the different water sources. Plots of Sr-87/Sr-86 versus dissolved organic C, B, and NH4+ defined perpendicular trends, documenting where leachate or sea water mixed with uncontaminated groundwater, and demonstrating that le achate has not contaminated groundwater in aquifers beneath the landfill.
