U.S. President Donald Trump has authorized emergency assistance for Washington D.C. in response to a significant sewage leak into the Potomac River. According to Jin10, the incident involved the rupture of a decades-old sewage pipeline in Maryland on January 19, resulting in the discharge of over 940 million liters of untreated sewage into the river. The Potomac River, which flows through the western part of Washington D.C., serves as a primary drinking water source for the capital region. This event is considered one of the largest sewage leaks in U.S. history. On February 18, Washington D.C. Mayor Muriel Bowser declared a state of emergency and requested federal resources from President Trump to assist the city in managing the sewage system breach.
