Clean Water Act: EPA won’t regulate pollution that moves through groundwater
EPA won’t regulate any pollution to surface waters that passes through groundwater. … If pollution travels through groundwater, EPA says, it “breaks the causal chain” between a source of pollution and surface waters. That could affect regulation of pollution from a variety of sources, including seepage from coal ash and manure management ponds, sewage collection systems, septic system discharges, and accidental spills and releases.
