What does the Groundwater Environmental Indicator deal with?

The "Migration of Contaminated Groundwater Under Control" environmental indicator pertains to the physical migration (i.e., further spread) of contaminated groundwater and contaminants within groundwater (e.g., non-aqueous phase liquids or NAPLs). It also includes the interaction of contaminated groundwater with surface water.
