The above comes from the updated U.S. Army Corps of Engineers Dredged Material Management Plan. Let me translate this for you in a nutshell. Harbors and shipping channels fill in with sand and organic material over time that have to be removed in order to make boat passage safe. Some of the material is clean and used beneficially to rebuild beaches and reefs, but the majority of it is contaminated with highly toxic chemicals that have accumulated over the past 2 centuries.
The A.C.E. used to simply dig this stuff out of one area, then dump it in the water somewhere else. But there were a lot of problems and people began to protest what was going on. It is now very difficult for them to do this as everyone is watching. So they look for other ways to recycle and dump this material. (NYS soil cleanup standards are less stringent than most states in the region.)
Remediating the "toxicity" at Willets Point in order to dump additional toxic materials there sounds like something the city, state and federal governments would work on together (Willets Point Headscratcher Series #3). The City has planned for certain businesses to get rich there and it's not the ones who currently own the land. Dumping this crap on Heritage Field, where neighborhood kids from the South Bronx are supposed to play after Yankee Stadium is torn down, and at Ridgewood Reservoir, a proposed nature sanctuary bordered by a not-so-wealthy Brooklyn town, are also logical places for contaminated garbage. Rockaway? Yes, please send some nasty stuff there, too, to replace the nasty stuff being taken out. Notice how all the dumping is being targeted for outer boroughs. Rest assured that the City has already agreed to this plan, otherwise ACE wouldn't have put it in the report.
Ask yourself why your elected officials aren't showing a bit of concern about this. We have 3 tweeders who are running for public advocate who should be all over this, not to mention the one who currently holds the office. Also ask yourself why you are reading this here first instead of in a daily newspaper.
