Gowanus Canal contamination: NY investigating 100 blocks for potential toxins in air and soil
GOWANUS, Brooklyn (WABC) — New well being considerations that have an effect on residents alongside the Gowanus Canal in Brooklyn are being investigated.
An environmental database agency, referred to as Toxics Focusing on, discovered ranges of air toxins inside one constructing close to the Gowanus Canal to be 450 occasions the State Well being Division’s really helpful threshold.
The agency additionally discovered excessive ranges of poisons in close by soil.
With new development within the space, residents are involved it could possibly be unleashing new points or contributing to previous ones.
Seth Hollinger, a long-time resident of Gowanus, wonders what the current explosion of improvement within the neighborhood, which is a superfund website, will do to the chemical substances buried deep within the soil.
A superfund website is a location polluted with hazardous supplies.
Hollinger’s group, Voice of Gowanus, has teamed up with Walter Cling of Toxics Focusing on, an environmental database agency to uncover the info about toxins within the space.
“It looks as if widespread sense that you’d construct and clear land first. However that does not appear to be the case and it is of nice concern not just for constructing, however for current residents,” Hollinger mentioned.
Since final September, the Division of Environmental Conservation has quietly investigated about 100 blocks for contamination together with testing the soil and air.
“One property referred to as ‘Property Two’ had 900 micrograms per cubic meter of trichloroethylene within the indoor air. The allowable quantity is just two micrograms per cubic meter,” Water Cling of Toxics Focusing on mentioned.
The chemical trichloroethylene has been linked to Parkinson’s Illness.
Cling mentioned the state knew, however didn’t warn the general public.
“We’re telling the governor that each single property inside a thousand ft of each Brownfield has received to be investigated after which mitigated to guard public well being,” Cling mentioned.
DEC Interim Commissioner Sean Mahar addressed considerations throughout a press convention on Monday.
“Clearly, what you are seeing play out here’s a coordinated federal, state and native push to deal with legacy contamination within the space,” Maher mentioned. “EPA is answerable for the canal cleanup treatment, and we’re overseeing brownfield and state Superfund cleanups all through the world as effectively. And all that’s being performed in direct coordination with all of the entities with the work underway. And clearly, we take nice pleasure and holding the group knowledgeable of all of the work that’s underway.”
To handle the group’s concern relating to soil vapor intrusion from the economic legacy of the Gowanus Space, DEC is finishing a Gowanus Space Huge Soil Vapor Intrusion Investigation.
Presently, the house owners/tenants of roughly 100 properties agreed to permit New York State to check their indoor air as a part of the Gowanus Canal area-wide SVI examine.

NYSDEC launched an announcement relating to the Gowanus Canal:
The Division of Well being (DOH) and the Division of Environmental Conservation (DEC) are dedicated to holding the group knowledgeable of present actions on this and different State cleanups. Within the Gowanus Canal space, the companies have launched quite a few group updates (obtainable on the DEC web site Gowanus Canal Space Websites – NYSDEC); held two group availability classes; recurrently engages and presents data to residents teams together with EPA’s Neighborhood Advisory Group, legislators (see right here), and different conferences as requested; and this week shall be posting an intensive Often Requested Questions doc, amongst different sources.
DOH and DEC contact every property proprietor to relay the outcomes of the sampling occasion and to debate whether or not mitigation is warranted. Property house owners have been notified of the tenant notification regulation. Particular soil vapor intrusion (SVI) outcomes from personal properties, which aren’t below an settlement or order with the DEC, are shared with constructing house owners and occupants however usually are not shared publicly due to privateness issues. Whereas SVI outcomes from 543 Union Road indicated the necessity for fast motion, there have been no detections in occupied components of the constructing near the cited degree. Upon receipt of the SVI sampling outcomes, DEC carried out fast motion within the 543 Union Road constructing to deal with SVI concentrations inside occupied areas. Lengthy-term engineering controls to deal with SVI at 543 Union Road (managed by U.S. EPA in coordination with DEC and DOH) and different properties are being carried out with shut oversight by DEC and DOH.
In 2023, DEC referred the 543 Union Road property indoor air mitigation program to the EPA’s Removing Motion Department. EPA has since taken a number of actions to scale back contaminant ranges in indoor air at this property. The analytical outcomes of current indoor air samples collected from the constructing indicated that the concentrations of TCE within the occupied items are effectively beneath each the DOH’s and EPA’s motion ranges and protecting of public well being.
Extra questions relating to 543 Union Road ought to be directed to the EPA.
The Voice of Gowanus says the take a look at outcomes ought to be extra extensively distributed to the general public so residents know which areas to keep away from, calling for extra testing and extra transparency.
