The board of directors of the District of Columbia Water and Sewer Authority voted to remove CEO David Gadis after facing mounting criticism for his management following a significant sewage spill. This incident, which occurred in January, resulted in over 240 million gallons of raw wastewater being discharged into the Potomac River, marking the largest sewage spill in U.S. history. The decision was made shortly after a debate among leading mayoral candidates Janeese Lewis George and Kenyan McDuffie, where they expressed differing views on Gadis's leadership. Lewis George, a socialist councilwoman, firmly stated that Gadis should be removed, while McDuffie, a centrist, expressed uncertainty but acknowledged that the responsible party should be dismissed. The board's action follows allegations from the Department of Justice that DC Water violated the Clean Water Act and an ongoing investigation by House Republicans. Gadis will remain in his position during a transition period as the board searches for a successor, and an online dashboard has been launched to monitor the water quality of affected rivers.
