GREENLAND — The U.S. Environmental Protection Agency has released data summarizing the results of recent fish tissue sampling conducted at Berry’s Brook.
According to Kelsey Dumville in the public affairs office, under EPA and New Hampshire Department of Environmental Services oversight, eel, shiner, pickerel and brown trout from five locations in the brook were tested for per and polyfluoroalkyl substances.
The contaminants perfluorooctanoic acid, perfluorooctanesulfonic acid and perfluorononanoic acid were detected.
Dumville said the highest concentrations of PFOS were found in eel and shiners from the Lafayette Road testing site. These levels were below what would be considered an unacceptable risk to children and adult who consume these fish, she said.
“EPA is conducting a data validation review for this fish tissue data and report to ensure the accuracy of the data,” Dumville said Tuesday.
The sampling took place from June 11 to 14, starting at Lafayette Road and progressing downstream to Brackett Road.
A total of 178 individual fish were captured during the testing. They included red fin pickerel, golden shiner, striped bass, American eel, banded sunfish, brown trout, pumpkinseed sunfish, brown bullhead and flounder.
Fish tissue from the single largest brown trout caught and analyzed had one of the lowest PFAS concentrations of the samples analyzed, according to the laboratory results.
The testing was conducted because contaminants were found in surface water near Coakley Landfill and residents are concerned that it is contaminating the fish they consume.
New Hampshire Fish and Game officials issued a catch-and-release only emergency rule earlier this year so testing could be performed.
