County officials discovered a large sewage spill Sunday afternoon in Baltimore County.
An estimated 300,000 gallons of sewage seeped into a wooded area southwest of Cub Hill Road, near a tributary to Gunpowder Falls.
The overflow was the result of a vandalized manhole. The manhole cover had recently been removed and the 12-inch diameter line had been blocked with rocks.
Baltimore County Utility crews responded when a local resident reported the overflow on Sunday.
Crews brought in heavy equipment and deployed an emergency pump-around which stopped the overflow at 10:00 a.m. Monday morning.
The Baltimore County Department of Health will monitor water quality in the area affected by the overflow, and will publish water contact advisories as necessary on the Department’s website.
