Description: CRREL Report
Abstract: This report describes a dynamic study of the effects of well screen materials on the chemistry of groundwater during contact periods that are consistent with compliance sampling. Tests were done by passing TCE-contaminated aquifer water through monitoring well screens held in a special chamber, without significant changes in major water quality parameters. The results indicate that polymeric materials (i.e., rigid polyvinyl chloride and polytetrafluoroethylene) do not influence aqueous metal and TCE concentrations, while stainless steel casings significantly influence aqueous concentrations of Cr, Ni and Fe, especially after developing surface corrosions.
