Public Health Warning Issued Related to Recent Sewage Discharge

The Massachusetts Water Resource Authority confirmed a combined sewer overflow at Outfall MWR203 in Charlestown, beginning on May 9 at 7:03 p. m. and concluding at 9:27 p. m. This incident has prompted a public health warning, urging residents to avoid contact with the Charles River and Inner Harbor for a minimum of 48 hours due to health risks associated with bacteria and pollutants.

The advisory expires at 9:27 p. m. on May 11, following the end of the overflow.
