Ground Water Issue

Conventional pump-and-treat technologies are among the most widely used systems for the remediation of contaminated ground water. Within recent years it has become recognized that these systems can require protracted periods of time to make significant reductions in the quantity of contaminants associated with both the liquid and solid phases which constitute the subsurface matrix. Evaluating the effectiveness of pump-and-treat remediations at Superfund sites, as well as attempting to improve this effectiveness, are issues identified by the Regional Superfund Ground Water Forum as a concern of Superfund decision makers. The Forum is a group of ground-water scientists and engineers, representing EPA’s Regional Superfund Offices, organized to exchange the most recent information related to ground-water remediation at Superfund sites.
