PORTSMOUTH, N.H. (AP) - Portsmouth officials say six rounds of sampling done for chemicals in wells at what’s now the Pease International Tradeport have resulted in non-detect levels since the city began using a carbon filter system.

Public Works Department deputy director Brian Goetz tells The Portsmouth Herald (https://bit.ly/2g54FNh ) the last test was done on Nov. 15. He says all six tests resulted in non-detect levels for two types of PFCs, or perfluorochemicals.

Goetz says they used the same sample method as the Air Force at the two city-owned wells still operating at the former Pease Air Force Base.

The city installed the treatment system in September.

The city of Portsmouth closed the Pease base’s Haven well in May 2014 after high levels of perfluorooctane sulfonic acid were found in its water supply.
