Hydrilla Treatment
Village of Croton-on-Hudson E-Notice

Update from the NYSDEC:

The NYSDEC led Croton River Hydrilla Control Project is proceeding as expected. Pre-treatment aquatic plant surveys were completed on foot, by boat, and using a drone prior to treatment. Herbicide treatment began July 6, 2017 and the hydrilla is showing definite signs of damage from the fluridone.

As per the established protocol developed by DEC, the Village of Croton on Hudson and NYSDOH, we have switched from weekly to daily sampling and analysis of the drinking water because the concentration of fluridone in two wells is between 1-1.4 parts per billion (ppb). All finished water samples (the water actually used by residents) continue to show detections well below 1 ppb. Fluridone levels in both the wells and finished water are still far below the USEPA label limit of 20 ppb within ¼ mile of a drinking water intake. All results of drinking water sample analyses are posted regularly on the project webpage. The Five Year Management Plan, which includes detailed information about the project and sampling protocol, is also available on the project webpage

The next public meeting will be held on Wednesday, January 24, 2018 from 6:30 pm – 8:45 pm at the Stanley H. Kellerhouse Municipal Building, 1 Van Wyck Street. DEC will discuss the project’s progress. This is an additional opportunity for community members to ask questions.
