On July 18, a fast-moving intense summer thunderstorm whipped through the region, resulting in a short burst of rain - and a flood of raw sewage into the water.
Here's what it looked like in Kingston:
Video loading...Combined sewers carry both raw sewage (laced with pharmaceuticals and other household chemicals) and runoff (including oil, grease, road salt, litter and other road pollution carried off when the rain courses over the pavement into storm drains). Grass clippings figure prominently in the surface detritus in the video above, along with cigarette butts and bottle caps. Imagine a storm drain on the street and your toilet, both emptying into your creek or river together in a torrent. That's a CSO.
Take a look at that video, and then multiply it by about 660. That's what happens to the Hudson River when it rains.
There are 58 CSOs, each something like this in the Hudson River communities of Westchester County, Newburgh, Poughkeepsie, Kingston, Hudson, Catskill and the U.S. Military Academy at West Point. There are about 90 more in the Capital District, another 52 in the Mohawk River and 12 more in the Upper Hudson north of Troy. New York City has at least 426 CSOs, and New Jersey's Hudson River shoreline another 26.
$2.5 billion, incidentally, is roughly
the documented cost of wastewater infrastructure fixes needed just in the Hudson River Watershed -
not including huge investments needed in New York City or New Jersey. In just a portion of that watershed - the 10 counties between the Capital District and Yonkers - only about 30% of communities have even documented their need for wastewater improvements. So the overall bill to stop sewage overflows and leaks, and to improve treatment to meet the needs of wildlife, recreational users - and the 100,000 people who rely on the Hudson for drinking water - is much larger.
