Title: Evaluating ground water plumes under the hazard ranking system. Fact sheet

This fact sheet provides information on potential National Priorities List (NPL) sites evaluated as contaminated ground water plumes with no identified source of contamination and how such sites are evaluated under the Hazard Ranking System (HRS). It defines steps that should be taken before a ground water plume can be evaluated as a source of contamination and summarizes scoring considerations for sites that consist solely of a ground water plume. Responses to commonly asked questions about evaluating contaminated ground water plumes at potential NPL sites are also presented. This fact sheet provides guidance only and may be amended by EPA on a site-specific basis.
