Flooding on Neptune Ave. in Coney Island after Hurricane Sandy hit the area.

study from the group Climate Central says northeast waterways were swimming in sewage following Sandy — much of it untreated.

In order to prevent a similar overflow from happening again, Alyson Kenward, a senior scientist at Climate Central, says local governments should consider “moving critical components of the infrastructure at treatments plants and raising them up higher, installing water-proof gates at facilities.” She added that governments should also establish a "protocol" for steps to be taken in the event of an emergency. 

Four of the five biggest releases of untreated and partially-treated sewage happened in New Jersey or New York.

  1. Passaic Valley Sewage Commission – Newark, NJ – 3.8 billion gallons
  2. Bay Park Sewage Treatment Plant – Nassau County, NY – 2.3 billion gallons
  3. Yonkers Joint Wastewater Treatment Plant – Yonkers, NY – 1.2 billion gallons
  4. Middlesex County Sewerage Authority – Sayreville, NJ – 1 billion gallons
  5. O Street Combined Sewer Overflow – Washington, DC – 475 million gallons

All figures are estimates. With sea levels are predicted to rise as much as two feet in the next century, the study’s authors say now is the time to upgrade infrastructure.
