TROY, N.Y. (NEWS10) — Due to concerns regarding PFOA contamination in water supplies, Rensselaer County, in conjunction with the NYS Department of Health and NYS Department of Environmental Conservation, has started a groundwater study in the area around Petersburgh.
As part of the study, the County says they began sampling public and private water supplies initially within a half mile and then a mile of Taconic located in the Town of Petersburgh. All municipal ground fed water supplies and the Troy water systems were tested as well.
The results of the recent municipal system samples taken are below:
Location PFOA count
Schodack Water District 1 Non Detect*
Schodack Water system Non Detect*
City of Troy Water 2.5 ppt
*Non Detect indicates less than .67 ppt. The lab testing was performed by Pace Analytical through Bender Labs. Pace Analytical is an Environmental Protection Agency Certified Lab.
With these results of the municipal water supplies the County has completed testing of all ground fed municipal water supplies and the Troy water system. The previous systems tested include Petersburgh, Berlin, Schaghticoke, Hampton Manor , Nassau, and Castleton.
All sampling except the Town of Petersburgh’s results indicated PFOA counts below 20 ppt.
Results on an additional 9 private well samples in the Town of Petersburgh returned results of:
- 3 samples below 20 ppt
- 1 sample between 21 ppt and EPA Guidance level of 100ppt
- 1 sample between 101ppt and 1000 ppt
- 1 sample between 1001 and 2100 ppt
- 3 samples were non detect (less than .67 ppt)
A breakdown of the results of 62 samples taken at private homes mainly within a mile of Taconic located in the Town of Petersburgh are:
- 16 samples below 20 ppt
- 8 samples between 21 ppt and EPA Guidance level of 100ppt
- 14 samples between 101ppt and 1000 ppt
- 7 samples between 1001 and 2100 ppt (the highest result found was 2100 ppt)
- 17 samples were Non Detect (less than .67 ppt)
The 62 water samples were taken at 50 homes as some homes already had water treatment systems installed. Therefore a test was taken before the treatment system and post treatment system in order to assess the impact of the current treatment system. Currently, the County is awaiting results on 21 previously taken samples.
The County in conjunction with the NYS Departments of Health and Environmental
Conservation is continuing the water testing program and will release the results as they become available. Results have been provided to the homeowners and municipalities tested. Under an agreement between the NYS Department of Environmental Conservation and Taconic private water sources with a PFOA result of over 100 can have a filter system installed on their home by Taconic. Installation of the filter systems began today.
