Force polluters to comply with or government to enforce environmental laws.

How It Works

  1. FILE COMPLAINTS: We file complaints with the state when a polluter is no longer in compliance with laws.
  2. SUE ILLEGAL POLLUTERS: With our partners, we bring lawsuits against polluters who have failed to operate in compliance with environmental laws in order to bring them into compliance.
  3. CHALLENGE REGULATIONS IN COURT: We challenge regulations in court to improve systems and better protect our waterways.

Don’t Mess with Success

The Clean Water Act has been an unmitigated success since it was passed in 1972. So why is the Trump administration rolling it back? Back then, more than two-thirds of U.S. waters were unfit for swimming, fishing, or drinking water use.  The Potomac River had been declared a national disgrace, Lake Erie was dead, and […]

Comments to 2018 Virginia Water Quality Assessment Integrated Report

Great news!  We succeeded in our efforts to resolve the nitrogen pollution violations at Frederick’s wastewater treatment plant — the city successfully completed a $45 million upgrade to the plant after delays of several years.

Court Vacates ACP Permits

Yesterday, the Fourth Circuit Court of Appeals unanimously vacated the permit issued to Dominion Power by the National Park Service (NPS) for a right of way under the Blue Ridge Parkway, a critical component of the 600 mile Atlantic Coast Pipeline (ACP).

Chesapeake Bay Cleanup Mid-Term Report: More Work Needs to Be Done

The Chesapeake Bay Cleanup Mid-Term Report came out on July 27 — lots of scientific jargon, but the bottom line is that the region only achieved about 40 percent of its nitrogen reduction through the end of last year. I certainly care about the Chesapeake Bay, but my day to day dedication is about the […]
