The New Hampshire Department of Health and Human Services has released a report on the blood testing program results related to chemical exposure at the Pease Tradeport.
The state has concluded that people exposed to contaminated water at the former Pease Air Force Base had "significantly higher concentrations" of three types of perfluorochemicals, or PFCs, than the national average.
The report was released before a meeting Thursday night in Portsmouth by state health officials.
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.
During two separate, two-month periods in 2015, the department facilitated blood tests for nearly 1,600 people.
