Mississippi Governor Declares Water Emergency For Jackson

The city is facing dual water issues: receding floods from the Pearl River have led to low water pressure, affecting daily activities like flushing toilets and doing laundry. Additionally, a boil water notice is in effect due to bacterial contamination, making the water unsafe for consumption or even brushing teeth. In response, Mississippi's governor has declared a state of emergency, and the National Guard is distributing water for essential uses.
