Hurricane Sandy caused 84 million gallons of sewage runoff in Md., report says

Hurricane Sandy's rains caused 84 million gallons to run off into Maryland bodies of water, according to a report by research organization Climate Central.

In New York and New Jersey, meanwhile, more than 5 billion gallons of sewage spills are estimated to have occurred. The District of Columbia also had more spillage than Maryland, with 475 million gallons from a single pumping station.

Nearly half of Maryland's estimated total came from sewage overflows related to heavy precipitation. Much of that was at pumping stations around Cumberland, where snow also fell during the storm.

At the Little Patuxent Water Reclamation Facility near Savage, a power outage led to nearly 20 million gallons of untreated sewage to bypass the plant and flow into the Little Patuxent River. "Howard County officials reported that there was no immediate danger to the local ecosystem or drinking water after the storm, because the spill had been so diluted by the heavy rainfall," the report notes.

In other cases, a total of nearly 7 million of gallons of sewage came out of manholes in Baltimore, Parkville and other parts of the city and county because of heavy precipitation.

Maryland saw some of Sandy's heaviest rains, including the storm's highest total measured in the U.S., with nearly 13 inches in the Eastern Shore town of Bellevue.
