Abstract:
Polycyclic aromatic hydrocarbons (PAH) are present in groundwater in the Pinal Creek basin near Globe, Arizona. The maximum concentration of quantified PAH in samples from monitoring wells was 35 micrograms per liter. PAH contamination was found in a plume about 11 kilometers long. The source is probably in an area of active mining operations several kilometers upstream from the sample wells. Concentrations of quantified PAH in the aquifer decrease significantly as the pH rises above 4. Concentrations of dissolved organic carbon (DOC) decrease in the same area. The fractions of the DOC that decrease are predominantly dissolved humic substances (DHS). Analyses of the data indicate that partitioning of PAH onto DHS could be taking place and the removal of PAH could be controlled by the adsorption of DHS onto metal hydroxides.
