Summary:Lead poisoning is a threat to children. Lead does not breakdown remaining in the soil. The purpose of this study is to conduct a spatial analysis of soil Pb values in Jersey City and attempt a temporal and source analysis using Pb isotopes. In a previous study, surface samples from different parks in Jersey City, were analyzed. Of the 29 samples collected, 12 exhibited values above the residential limit of 400ppm Pb. One site, Hamilton Park, had Pb levels at 550ppm. Hamilton Park, founded in 1830, was surrounded by foundries in the late 19th and early 20th century. It lies close to the NJ Turnpike and Holland Tunnel. Using a Geoprobe, an 8ft core from the park was retrieved. This core will be finely sectioned. To determine the source of the Pb, the < 63fYm fraction will be digested and analyzed using an ICPMS and the Pb isotope ratios will be determined. The ratios of the Pb isotopes 206Pb/207Pb, will allow us to discern where the Pb came from. Lead from smelters have higher ratios of 206Pb/207Pb, while lead from leaded gasoline have lower ratios (Lima, 2004). A GIS map will be prepared as part of the spatial analysis. The GIS will show historic fills, known contaminated sites, sample locations, and other locations of interest. One of the goals for this research is to provide the city of Jersey City with the information regarding the source of the lead. This is crucial for abatement and remediation. Our earlier results were the basis for an ordinance that provided for children to receive free blood Pb level testing in Jersey City. And it is our hope that this research will help the city in deciding whether to cap the existing sites, remove the material or do some other type of clean up.
