EPA assesses storm impacts at Dewey Loeffel Superfund site in Nassau | New


CITY OF NASSAU, NY – City of Nassau Supervisor David Fleming provided residents with an update on the condition of the Dewey Loeffel Superfund site following recent storm damage.

EPA is expanding testing along Valatie Kill due to damage to areas surrounding the Dewey Loeffel Superfund site following Nassau’s request.

The EPA is also coordinating with the New York State Departments of Environmental Conservation and Health and the General Electric Company, one of the companies carrying out the work at the site, to assess the short- and long-term intervention measures. The EPA also coordinates with the City and Village of Nassau. After the storm, surface water samples were taken at Little Thunder Brook and Valatie Kill to assess current conditions.

According to the EPA, the results of the sampling are expected before the end of July. The EPA also observed sediment deposits in floodplains in several areas along Valatie Kill. The EPA will oversee the sampling of this material by Friday, July 23, and oversee additional sampling once surface water flow in the Valatie Kill calms down. Turbidity control measures, such as stone dams, are also being reinstated in Little Thunder Creek to limit the potential for sediment movement downstream.

“The PCBs that we are talking about tend to cling to the ground, so what we would expect is that this light sediment that was in the Little Thunder Brook has now been introduced into the Valatie Kill,” Fleming said.

“At what levels? That needs to be determined, which is why we need to do further testing,” Fleming explained.

Fleming also urged residents to contact the EPA if they notice said accumulations of sediment.

“The EPA has committed to doing additional testing south of Mead Road, which heads towards Lake Nassau. So if you have a buildup of sediment on your property due to the high waters of the Valatie Kill from this storm , I encourage you to contact the EPA, “Fleming remarked.

Additionally, Fleming commended the EPA and NYSDEC for their swift response and noted that the city is taking a proactive approach to monitoring the site.

“We are doing this to be proactive, we are not trying to alarm you. The town has pointed out since the start of the Little Thunder Brook remediation that we felt the test levels, the height of the water Possible Little Thunder The books during the storms the scientists examined were inappropriate for the high water levels we have seen in the town of Nassau over the past 20 years, ”Fleming remarked of runoff levels transporting sediment.

“We can no longer call 100-year floods, 100-year floods when they occur every two years. It was an event that went way beyond the 100-year floodplain in Little Thunder Brook in places and it still remains to be seen. determine how much damage has been done to Little Thunder Creek. The reason we are concerned is that recent test results on Little Thunder Creek show that there is still a significant amount of contamination on the banks of Little Thunder Creek which are not even near the water levels that we would see in Little Thunder Brook, meaning that the contamination is susceptible to erosion and can be transferred into the ecosystem and certainly into the Hudson River tributary system which understands the Valatie Kill, ”Fleming continued, assessing the damage.

“The damage we saw at Loeffel has been a question for a number of residents. The Dewey Loeffel landfill site itself, the plug remains intact based on the initial inspections. There does not appear to be any large or major discharge from this area, there is obviously a lot of surface water discharge, ”Fleming added of the latest reviews on the site.

Fleming also noted that the city will ask the EPA to review the water treatment facility as well.

“One of the things we are concerned about is the resilience of the water treatment facility that was built by the EPA several years ago. I expressed my concern when building it early. I think she ignores the high water resiliency requirement and we’ll ask the EPA to review that as well, ”Fleming said.

In addition, Fleming called on authorities to take serious care of the site, which poses a threat not only to Nassau but to the greater capital region.

“The Dewey Loeffel landfill needs to be completely decontaminated, which means the excavation of the entire site, the complete decontamination of Little Thunder Brook,” Fleming said.

“You can’t put bandages on gunshot wounds. You have to make sure all that contamination is removed. If you don’t, you continue to pollute the entire Hudson River estuary system,” he said. Fleming explained.

“So it’s not a problem that one community faces. It’s a problem that the entire capital region faces,” Fleming added.

If your residential property is located in the village or north of the village and you have observed sediment deposits on your property, you are encouraged to contact Joseph Battipaglia, EPA Remediation Project Director at 518-407- 0400, ext. 4.

Although sediment deposits do not pose an immediate short-term health risk, the EPA recommends that you avoid direct contact with sediment that may have been deposited on your property until the EPA assesses it.
