NEW YORK (April 30, 2013)--Superstorm Sandy released 11 billion gallons of sewage from East Coast treatment plants into bodies of water from Washington, D.C., to Connecticut, according to a study by the nonprofit science journalism group Climate Central.
The report says the amount is enough to leave Central Park 41 feet deep in sewage.
Most of the overflow was from storm-surge flooding that inundated sewage treatment facilities.
The sewage spilled into surrounding waters and even some city streets, most of it in New York City and northern New Jersey.
The study found one-third of the spilled sewage was untreated.
Ninety-four percent was because of coastal flooding damage.
The report estimated the cost of repair to damaged plants at nearly $2 billion for New York and $2.7 billion for New Jersey.
The report was based on data from state agencies and treatment plant operators.
