POSTPONED INDEFINITELY: PFAS INFO SESSION ORIGINALLY SCHEDULED FOR APRIL 7
March 24, 2020:
- Tighe & Bond released the list of home wells to test as part of radius 4 (see Radius 4 Well Test List below). Homeowners will be notified that we don't know when the testing will begin because of the COVID-19 precautions.
- The list of test results has been updated and can be found below (see March Summary)
- Since there are many homeowners who are interested in having their wells tested for PFAS, Tighe & Bond has shared their testing protocol with us. Please note that homeowners are encouraged to use either Con Test or Alpha, for consistency. The testing protocol and a document describing how to interpret the test results can also be found below.
March 9, 2020: Thomas Prince School had non-detectable levels of PFAS.
March 3, 2020: Tighe & Bond just filed an Immediate Response Action (IRA) Status Report and IRA Plan Modification (IRA) with MassDEP. You can find it here.
At the request of the Massachusetts Department of Environmental Protection (MassDEP), the Town recently sampled the drinking water well that serves the Princeton Town Hall complex to determine baseline water quality. As part of the sampling, we tested for a group of compounds called per- and polyfluoroalkyl substances, or PFAS. MassDEP’s current drinking water guideline for PFAS in public water supply wells is 70 parts per trillion (ppt, nanograms/liter) for five PFAS compounds combined. The sum of the results for these five compounds was over the 70 parts per trillion guideline. Because of these detections in the public water supply well, MassDEP required the Town to develop an Immediate Response Action (IRA) Plan that includes sampling of private wells within 500 feet of the Town Hall for PFAS. A link to the IRA is on this page. Subquent IRA updates will be added as they become available. See the IRA for details about testing, wells affected, and next steps.
Please note the Town is immediately providing bottled water to the homes with any level of detection and is working on getting remediation systems installed as soon as possible where needed.
Various documents and test results can be looked up on the MassDEP website using the Release Tracking Number 2-21072.
If you have any further questions after reading the information provided on this page, please contact Town Administrator Sherry Patch at (978) 464-2102.
