Pownal water district facing permanent PFOA filtering
Representatives from Unicorn Management Consultants, which is overseeing the response to perfluorooctanoic acid contamination of the water system, said there have been no further talks with the owner of a potential well site that was under consideration late last year.
The report will look at long-term solution to address the PFOA contamination, which now is being eliminated by an enclosed carbon filtering system installed near the district well head off Route 346.
The idea was rejected by the board as inadequate.
Board members were especially critical of a plan to hand over to the district maintenance of the filtering system after three years.
Another potential issue with long-term filtering came up during the meeting Monday, when resident Jim Winchester brought in a blackened water filter element from a rental property he owns within the water district.
O’Connor said Monday there had been no further contact with the property owner.
The consultants earlier considered a well site on the former Green Mountain Race Track property, but negotiations with the owners to allow preliminary testing broke down.
Currently, the track property off Route 7 is involved in foreclosure proceedings in Bennington Superior Court Civil Division.
State requirements Tim Raymond, chief of the Operations and Engineering Section of the state’s Public Drinking Water Program, notified O’Connor in an email in February that the improvements to the filtering system initially proposed by Unicorn would not meet Vermont water supply standards.
If a new well option is not possible, Raymond stated, then the insurer funding the contamination response should "account for the full construction improvement costs for the provision of a permanent [filtering] system, including operation and maintenance life-cycle costs for the water system for the duration of time where the well will be impacted by PFOA and/or PFOS."
