New report shows NYC was a virtual toilet after Sandy

A new report shows that Superstorm Sandy sent 11 billion gallons of sewage -- a third of it raw -- into streets, rivers, bays, canals and streets in the eight hardest-hit states, with 47% of the overflow occurring in New York in the weeks during and after the storm. Most of muck wound up in the waters of New York City and southern Jersey.

Imagine "Central Park stacked 41 feet high with sewage," to get an idea of the filthy deluge, the report by Climate Central, a New Jersey-based group that monitors climate change, suggested.

New York City reported six sewage spills larger than 100 million gallons and 28 larger than a million gallons, the report said. The storm severely damaged treatment plants and pumping stations and repairing them will cost New York state about $2 billion, according to Climate Central.

Climate change is increasing the risks of future overflows, the report warned: "Global warming has more than doubled the odds of a one in hundred year storm surge occurring within the next year."
