On November 6, 2019, with significant assistance from the NYS Department of Environmental Conservation (DEC), production and distribution of potable drinking water sourced from the Butterhill Wells resumed with the benefit of filtration through a newly constructed granular activated carbon filtration system (GAC system). DEC paid for all costs related to this GAC system.
Information on GAC filtration can be found on the EPA Website: PFAS Drinking Water Treatment Technologies
Before any water was distributed for use by Town residents, testing was conducted to ensure it did not contain any detectable levels of the PFOA/PFOS compounds, which caused the Town to shut down the wells in May 2019. A summary of those test results, together with a letter received from DEC regarding those results, both of which demonstrated these compounds were not detected in the treated water, were posted previously. A more complete summary of the test results can be found here. The more complete test results show additional PFAS compounds (commonly referred to as “short chain” PFAS compounds) are also reduced to undetectable (or non-detect) levels with the benefit of the GAC filtration. During the shutdown of the Catskill Aqueduct, DEC will continue to monitor PFAS levels in the treated water being provided to residents on a monthly basis. If PFAS compounds are detected in the treated water during this time, additional steps will be taken to ensure the water from these wells is filtered to non-detect levels or, to whatever extent possible, a different source of water will be used for provisions to the Town’s residents.
Please also note, since the new GAC system will only allow the Town to provide approximately 2.2 million gallons per day of potable drinking water from the Butterhill Wells, during the ten (10) week shutdown of the Catskill Aqueduct, not everyone will receive their water from this source. The following map shows where each area of Town, in general, will receive water from:
As shown in the map above, the east end of Town will receive a blend of water from the Butterhill Wells (marked “BH”) and from an interconnection maintained with the City of Newburgh. Barring any issues with the Butterhill site, the majority of water distributed to this area will be from the Butterhill Wells. Any water drawn from the City of Newburgh during the shutdown is from Brown’s Pond and is treated to non-detect levels through their GAC filtration system.
Another area of Town will receive water during the shutdown solely from an interconnection maintained with the Town of Newburgh (see area on above map marked “TN”). This water is sourced from the Delaware Aqueduct and/or Chadwick Lake, both of which do not, to our knowledge, contain any detectable levels of PFAS compounds.
Finally, the west end of Town will receive a blend of water sourced from the Butterhill Wells and the Kroll Well. Water from Kroll Well is also treated through a GAC system and is tested on a monthly basis. Click on the following links for the most recent test results on Kroll
Please note, the shutdown of the Catskill Aqueduct was initially scheduled to begin on October 7th, but was delayed. It began on November 11th and is scheduled to last for ten (10) weeks. Once it is over, it will take approximately one additional week until the system is fully operational. A decision as to where the Town’s water will be sourced following the ten (10) week shutdown has yet to be made. As decisions are made and/or more information becomes available, we will update the Town website and use other means to keep everyone apprised. If you have questions in the meantime, please call the Town Attorney’s Office at 845-563-4630. They will do all they can to respond to your inquiries or direct you to someone else who can.
Today, with significant assistance from the NYS Department of Environmental Conservation (DEC), production of potable drinking water sourced from the Butterhill Wells has resumed, with the benefit of filtration through a newly constructed granular activated carbon filtration system (GAC system).
Testing of the filtered water has shown the GAC system is effectively and successfully reducing any PFOA/PFOS contamination to non-detect levels, as can be seen in the linked correspondence and chart of test results.

On August 13, 2019, after the NYS Department of Environmental Conservation (DEC) installed a Granular Activated Carbon filtration system (“GAC system”) and with approval from the Orange County Department of Health (DOH), the Town of New Windsor placed Kroll Well back into service. Testing of the water filtered through the GAC system show it to be effective in filtering out the contamination that led to the well being taken off line. The Town will continue to operate and maintain the GAC system to filter the water from Kroll Well; and will see that monitoring and testing of the water, to ensure continued effectiveness of the GAC system, is conducted on a regular basis, as required by DOH. In addition to the water from Kroll Well, which is being distributed after filtration through the GAC system, the Town continues to supply water from the Catskill Aqueduct.

At the July 3, 2019 New Windsor Town Board meeting, it was announced that extensive talks between the Town, the NYS Department of Environmental Conservation (DEC), the NYS Department of Health (DOH), and the NYC Department of Environmental Protection (DEP) has led to an agreement whereby the State of New York will provide the Town with a temporary granular activated carbon (GAC) filtration system at the site of the Butterhill Treatment Plant.
As per the DEC, the system will be designed to remove PFAS, such as the PFOA and PFOS that were recently discovered in the water sourced from the Butterhill wells.
Design and installation will begin immediately with the stated goal of completion and operation in time for the planned shutdown of the Catskill Aqueduct on October 7, 2019. Until that time, the Town plans to continue providing its users with water that is sourced from the Catskill Aqueduct.
During the shutdown of the Catskill Aqueduct, which is expected to last 10-12 weeks, the Town plans to provide its users with water that is drawn from interconnections maintained with the Town of Newburgh (this water is sourced from the Delaware Aqueduct, Chadwick Lake and, at times, a blend of both Delaware and Chadwick Lake), water that is drawn from the Kroll Well (which is in the final stages of construction and testing of a similar GAC filtration system), and water from the Butterhill Wells, which will be treated through the aforementioned GAC filtration system. The DEC will continue to monitor both raw water, mid-point samples, and finished water samples from the Butterhill Wells during use of the GAC filtration system at Butterhill, in order to evaluate any changes in the levels of contaminants detected and determine if any additional action is needed. This continued monitoring will be part of the State’s continuing and ongoing investigation to determine the nature and extent of contamination in the area, which data and information will then be used to determine whether a permanent treatment system will be needed.
Any questions concerning the GAC filtration system at Butterhill can be emailed to [email protected] This inbox is monitored daily by the DEC, who will respond shortly after any such inquiry.
Once again, all Town officials would like to thank our residents and users for the continued support, understanding and cooperation as pertains to this issue. It is much appreciated!
