Testing


Test results have been reported in Parts Per Trillion (ng/L or ppt) when possible for consistancy in reporting. In some instances, results may be indicated in Parts Per Billion (g/L or ppb). To convert Parts Per Billion to Parts Per Trillion, move the decimal point three positions to the right. i.e.: 1.0 ppb = 1000.0 ppt. The EPA's Provisional Health Advisory for PFOA is 400.0ppt (or 0.4ppb).

The raw water in the 3 Municipal Wells have tested at ranges between 150ng/L (lowest contaminated well), to 662ng/L (highest contaminated well). The first action taken was to shut down the well with the highest contamination.

Private wells tested as of 1/20/16 that showed levels of PFOA ranged between 8.6ng/L at the lowest and 412ng/L at the highest.

The 5 groundwater test wells at the Saint-Gobain McCaffery Street facility have tested at ranges between 20ng/L and 18,000ng/L.

Graphical map of testing results from the Village, the NYSDOH, and Saint-Gobain. The private wells indicated are from the first and second rounds of private well testing completed by the NYSDOH. The Saint-Gobain exploratory well testing indicated can be seen in the complete report from Saint-Gobain. The map indicates where reportable contamination has been found. Levels indicated are from a point in time and do not indicate absolute numbers or account for natural variations in groundwater levels. The map will be updated with any new discoveries from ongoing testing.
Private Well Testing
If you have a private well that you would like tested, the New York State Department of Health has offered to assist. To request testing you can contact Albert DeMarco at 518-402-7860, or send an email to beei@health.ny.gov. If you have arranged for your own testing of your well, please notify the EPA of the results by contacting Larisa Romanowski at 518-407-0400 or romanowski.larisa@epa.gov. Because of limited staff and resources, private well testing in the vicinity of the known contamination area will be given priority over additional well testing.
