Environmental officials say the closing of a contaminated well near the main runway of the Portsmouth International Airport at Pease may lead to other wells being contaminated with high levels of a harmful chemical.
Portsmouth officials shut down the Haven well last year, after testing showed it has higher than safe levels of perfluorochemicals, known as PFOs.
Scott Hilton, project manager for the DES's Pease Superfund site, tells the Portsmouth Press Herald that contaminants now may flow into two wells south of the Haven well at the Pease International Tradeport.
Hilton said officials are testing the other wells to monitor for increased levels of PFOs.
