Monponsett Pond Aquatic Treatment
As part of a comprehensive Management Program being implemented by the Town of Halifax, Monponsett Pond (both the East & West Basins) will be treated with the USEPA/MA registered aquatic herbicides Sonar ONE & Sonar Genesis/AS (fluridone) to control non-native and invasive fanwort and milfoil. The initial treatment will be conducted on Tuesday, May 17th. The ponds will be closed to all water uses (including boating,fishing, and swimming) on the day of treatment only. Additionally, water from the ponds cannot be used for irrigation for a period of 90 days commencing on this day. Applicable water use restrictions will be posted with signs around the shoreline prior to application.
Following the initial treatment, it is anticipated that 2-3 additional, follow-up “booster” treatments will be required over a period of approximately 60 days. Notice of these follow-up treatments and any additional water-use restrictions will be made via subsequent posting of the shoreline prior to each treatment.
The project is being performed for the Town of Halifax under approved Orders of Conditions issued by the Halifax Conservation Commission (DEP File #171-0537) and the Hanson Conservation Commission (DEP File #175-0733) and a license (permit) issued by the Massachusetts Department of Environmental Protection. Treatments are being performed by the State licensed firm SOLitude Lake Management of Shrewsbury, MA.
