Many Portsmouth residents are worried over the results of blood tests for people who may have been exposed to water from a contaminated city-owned well.
Officials closed the Haven well at the Pease International Tradeport in May 2014 after testing found chemicals at levels 10 times higher than the Environmental Protection Agency's Provisional Health Advisory.
Hundreds of people have been tested to see if the chemical is in their blood, and those who found out they have elevated levels are concerned over the long-term impact — particularly on children.
State Epidemiologist Benjamin Chan recently reported that PFC exposure can potentially cause immune system effects, hormone dysfunction and other problems.
Testing will continue until Oct. 16. The Air Force is holding a meeting Wednesday to discuss cleaning up the wells.
