Partitioning behavior and the mobility of chlordane in groundwater

Batch solubility experiments showed an increase in chlordane solubility from 32 μg/L in pure (18 MΩ cm) water to over 400 μg/L in the presence of humic substances extracted from geologic material collected near a hazardous waste site in Memphis, TN. Solubility was also enhanced to 52 μg/L in groundwater collected upgradient of the site (total organic carbon, TOC=1.8 mg/L) and to 146 μg/L in downgradient groundwater (TOC=34 mg/L)
