Baltimore County officials estimate about 15,000 gallons of untreated sewage spilled into the creek that flows into Bird and Gunpowder rivers this week.
The sewage leaked from a damaged 8-inch sewer line that was damaged by recent heavy rains and a dislodged sewer manhole near White Marsh Run.
County utility crews completed temporary repairs Tuesday and have restored normal flow in the line. The county has posted signs advising residents to avoid contact with the waters of White Marsh Run and Bird River in the Silver Hill Farm West area in the eastern part of the county. Monitoring will continue on the site for the next several weeks.
The torrential rains last week also caused 2.6 million gallons of untreated sewage to spill from the Edgewood treatment plant at Aberdeen Proving Ground in Harford County. Much of the sewage from the plant's primary settling tank flowed into King's Creek and the Bush River.
