Turns out groundwater is not a point source
In February 2018, the U. S. Court of Appeals for the 9th Circuit held the Hawaii County of Maui’s pollutants were traceable to wells which discharge into groundwater and that groundwater was considered a point source under the Clean Water Act. But a new ruling has reversed that call and agriculture will benefit. The U.S. Court of Appeals for the 6th Circuit ruled on September 24, 2018 that the Clean Water Act (CWA) does not extend liabilitywhen pollution from a point source reaches surface water through groundwater movement.
