Bennington & North Bennington

State Continues to Review Conceptual Site Model for the East Side
The State has significant concerns with respect to the Investigation and Conceptual Site Model (CSM) report provided by Saint-Gobain on March 15, 2018. The State is conducting a comprehensive analysis of the work performed by Saint-Gobain to ensure that the final site investigation contains an accurately portrays the source of PFOA contamination on the East Site and ensures that the parties that polluted are held responsible.

Water Line Work on the West Side Starts Up Again
Water line work on the West Side of the site in Bennington and North Bennington has started up again for spring. You'll see construction activity on Murphy Road, Austin Hill, North Bennington Road, Bard Road, Red Pine Road, Walloomsac and Gypsy Lane. There will be minor work on Fairview, Vail, and Jennings’s drive.

By November 1, 2018, water main work is expected to be complete for the Town of Bennington and all impacted residences will be connected to municipal water.

Water line work started today for the Village of North Bennington’s public drinking water improvements project. In the coming weeks, you’ll see construction activity on Park Street, Matteson Road, Hillside, Riverside Drive, Harrington, River Road, Murphy Road, Ore Bed, Royal Street, Susan Taylor Lane, Matt Drive, Overlay, Hillside and Park Streets.

By August 1, 2018 , water main work is expected to be complete for the North Bennington planned improvements project, with all impacted residences being connected to municipal water.

Drinking water wells with PFOA levels under 20 ppt to be resampled
As part of the Agency of Natural Resources' effort to ensure protection of public health and to track long term PFOA contaminant levels in resident’s wells and groundwater, the Agency will begin sampling wells in the Area of Concern that have PFOA levels below 20 ppt before the end of the month. 

Representatives of Saint Gobain or the State will be contacting individual home owners about getting into your homes and taking these water samples. Sampling results should be received by the State and sent to individual home owners within 4-6 weeks from the sample date.

Sampling of POETs to Continue
POET (point-of-entry treatment system) sampling will continue following the schedule that's outlined in the Barr Engineering Corrective Action Plan, Corrective Action Area 1 – Operable Unit B, North Bennington and Bennington, POET O&M Manual.

The sampling frequency will continue on all POETs until they meet the performance standard in the Consent Order. The performance standard involves 8 consecutive quarterly sampling rounds with a PFOA concentration below 20 ppt along with a statistical trend of the sampling results over time showing concentrations either stable or declining.

For the homes on the west side that are being connected to municipal water, the POETs will be removed by CT Male and Culligan once municipal water is turned on to the home. Once this happens, sampling of these POET systems, and the wells, will cease. Sampling results will be sent to home owners 4-6 weeks after sampling.

State Plans to Hold Public Meeting in Bennington in Early May
The Vermont Agency of Natural Resources will have a public meeting in Bennington during the first or second week in May to present the most current information on the PFOA work in Bennington.

General topics will include the progress and future schedule of water line installation, the Agency’s current understanding of the site, highlights of the Barr Engineering report, and other topics. Bennington College will also present current findings of their research. The agenda, date and time, and location will follow in a future email once these details have been finalized.

Southern Vermont Regional Airport

Update on Sampling and Results
In March, the Agency's Department of Environmental Conservation collected drinking water samples from in and around the Southern Vermont Regional Airport property to assess if the Airport’s historic and current usage of Class B Aqueous Film Forming Foams (AFFF) for firefighting had impacted drinking water supplies around the airport. AFFF were historically formulated with PFAS ( per- and polyfluoroalkyl substances) , such as PFOA and PFOS, two chemicals that belong to the PFAS family.  

Five wells were sampled on the property and five wells surrounding the property were sampled for PFAS. The results were received in late March. Eight wells had no detections of PFAS compounds and two wells had detections of various PFAS compounds. The two wells, both located on Airport property, serve the Airport Business Park water system which serves 8 businesses and over 500 employees. 

A ‘Do Not Drink’ order was issued and the State is currently working with ATC Group Services of Williston and Otter Creek Engineering of Rutland to design a water treatment system for the Airport Business Park. The design plans and permit application for the treatment system are expected to be submitted this week.

Last Thursday, seven additional private drinking water supplies surrounding the airport were sampled. The sampling completed has not shown any PFAS contamination outside of the Airport property. A site investigation to assess soil and shallow groundwater impacts at the airport is in the planning stages and may start as early as next week.


Pownal Center
The Agency is working with the Attorney General’s office to ensure that groundwater contamination identified at the former Warren Wire Plant located on Central Street is characterized and remediated.

Pownal Village
The Agency continues to work with APU to address groundwater contamination identified at the former Warren Wire/General Cable facility. APU continues to maintain the carbon treatment system at the Fire District #2 Water system. APU is drafting an Evaluation of Corrective Action Alternatives. This evaluation will address the long-term impacts to the Fire District #2 Water system and is due to the Agency on April 26, 2018. A public meeting will be coordinated to discuss the recommendations outlined in this document.

North Pownal
EPA will be helping the Agency conduct additional groundwater characterization around the former Pownal Tannery lagoons and landfill to better characterize PFAS groundwater in this area. The Agency continues to maintain and monitor all POET systems and provide bottled water.
