U.S. Supreme Court
Question(s) Presented
1. Whether the Clean Water Act’s permitting requirement is confined to discharges from a point source to navigable waters, or whether it also applies to discharges into soil or groundwater whenever there is a “direct hydrological connection” between the groundwater and nearby navigable waters.
2. Whether an “ongoing violation” of the Clean Water Act exists for purposes of the Act’s citizen-suit provision when a point source has permanently ceased discharging pollutants, but some of the pollutants are still reaching navigable water through groundwater.
