Hurricane Sandy crippled sewage treatment plants in New York and New Jersey. The plants released hundreds of millions of gallons of untreated and partially treated sewage into the region's waterways. "You’re looking at significant expenditures of money to make the plants more secure," said John Cameron, an engineer and Long Island Regional Planning Council chairman. About $1.1 billion would be needed to fix plants in New York state alone, according to Gov. Andrew Cuomo.
