The New Hampshire Department of Health and Human Services has set deadlines for when people exposed to water from a contaminated city-owned well in Portsmouth can ask to be tested and when they must complete their blood tests.
The Portsmouth Herald reports the department stated that residents must request to be tested by May 29 and must have their blood drawn by June 12.
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.
Officials suspect the chemicals got in the well because of firefighting foam used on the former Pease Air Force base runway.
A department spokesman says "a funding stream will be identified" to cover testing costs.
