GREENLAND — New water filtration systems have been installed at Breakfast Hill Golf Club and a home next to the Coakley Landfill after the suspected carcinogen 1,4-dioxane was found to be above new state standards.
Coakley Project Coordinator Peter Britz, who also works as the city of Portsmouth’s environmental planner, said Friday they expect the carbon filters should provide an adequate remedy.
Water samples taken at the golf club Oct. 15 tested at .61 parts per billion.
At the 368 Breakfast Hill Road home, the water tested at .38 parts per billion.
Both properties were provided with bottled water until the carbon filters could be installed, even though the owners had invested in water filtration systems at their own expense.
Britz explained that water filtration systems are very specific as to what is to be removed and the systems installed did not use carbon filtration.
Coakley Landfill Group was required to provide the filters.
It includes the municipalities of Portsmouth, Newington, North Hampton, solid waste generators and solid waste transporters named potentially responsible parties in consent decrees which mandate cleanup of the landfill.
The privately owned landfill accepted municipal and industrial wastes from the Portsmouth area between 1972 and 1982.
Incinerator residue was also accepted for a refuse-to-energy project between 1982 and 1985, according to the United States Environmental Protection Agency.
