“FREMONT — School officials are taking precautions by installing new water bubblers at Ellis School after trace amounts of a chemical substance were found in the school’s well.

The School Board has asked Superintendent Allyn Hutton to move ahead with a plan to replace three bubblers with ones that have carbon filters in response to recent tests that showed the presence of per- and polyfluoroalkyl substances, commonly known as PFAS…

According to Hutton, the school already has one bubbler with a carbon filter and samples from its water showed no PFAS concerns.

The bubblers cost about $1,200 each, Hutton said…

The state DES has adopted a standard for two PFAS compounds, PFOA and PFOS. Hutton said the combined concentration of PFOA and PFOS was 20 parts per trillion, which is below the state’s standard of 70 parts per trillion for PFOA and PFOS combined.

Hutton said nine other PFAS compounds were also detected in the water, but DES and the federal Environmental Protection Agency don’t have regulatory standards or guidance for these compounds.”
