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!

The Town began the recent transition to the Catskill Aqueduct on May 1, 2019.  From that date until May 13th, water operations staff were assembled and the plant at Riley Road was serviced.  On May 13th, the Town began drawing water from the Aqueduct.  From May 13th until May 20th, the transition required a blending of water from the Butterhill Wells with water from the Aqueduct.  From May 20th until the present, the only water entering the distribution system and being provided to our residents has been from the Aqueduct.  The Town has not drawn from Brown’s Pond.

The Town is aware of certain odor and taste complaints with the water now being provided.  Any such issues are believed to be caused by the change in flow and treatment required to transition from the Butterhill source to the Aqueduct source.  Testing of the water is ongoing and will continue, as is required.  No safety issues have been identified.  

The Town has been flushing water through fire hydrants since June 17, 2019.  Flushing will continue through July 3rd.  This should alleviate most, if not all, of the current issues concerning taste and odor.

Please continue to contact the Town Attorney’s Office at 563-4630 with any further questions or concerns and thank you for your anticipated understanding.  

The Town of New Windsor Water Department will begin flushing fire hydrants on Monday,  June 17, 2019 and continue through Wednesday, July 3, 2019. Town residents and Stewart Airport occupants, as well as, the Fiirthcliffe Heights section of Cornwall may experience some water discoloration and low water pressure during this time. Please contact the Water Department at (845) 561-2550 with any questions or concerns. We apologize for any inconvenience.
