Union Leader Correspondent PORTSMOUTH — The city will be moving forward with the latest technology as officials here work to filter out contamination from drinking water at Pease International Tradeport.
The Haven Well was taken offline immediately when levels of PFOS were found to be more than 12 times higher than the U.S. Environmental Protection Agency’s health advisory.
The Haven Well is still offline.
On Monday, Deputy Director of Public Works Brian Goetz updated the city council on work planned at the Grafton Road Water Treatment Facility which provides drinking water in Portsmouth.
Goetz said the current plan is to add two resin filters and a granular activated carbon filter at the facility.
Goetz explained resin filters last longer but target specific contaminants.
The carbon filter will be able to treat some of the other legacy contaminants which remain in the water long after they were introduced.
“We are still very concerned about any legacy contaminants there,” Goetz said.
The Haven Well is expected to be back online in 2021, Goetz said.
Meanwhile, federal officials from the Agency for Toxic Substances and Disease Registry are planning to test people exposed to contaminated drinking water at Pease.
