HOOSICK FALLS, N.Y. (NEWS10) – The New York State Department of Health has released more water test results regarding the PFOA contamination in Hoosick Falls.

The tests were completed before the new filtration system was installed and operating.

The water samples were taken in January and February at the Hoosick Falls Water Treatment Plant. The level of PFOA at the plan was 983 parts per trillion, which is well above the new U.S. Environmental Protection Agency advisory level of 100 parts per trillion.

Other samples from the municipal water supply came back at 1,010 parts per trillion, also above the EPA advisory level.

The health department will now conduct new tests to determine PFOA levels since the new filtration system is running.

Residents are still advised not to drink or cook with the water.
