WALLOPS ISLAND, Va. (AP) – Federal authorities say an employee for a NASA contractor falsified pollution test results at the NASA Wallops Flight Facility.

Court documents filed Monday identified the now ex-employee as Monica Borowicz. The contractor wasn’t named.

Borowicz had worked at the NASA Wallops Flight Facility on Wallops Island.

The tests monitored Total Kjeldahl Nitrogen, or TKN, which is pollution associated with storm-water runoff and sewage. It contributes to algae blooms and depleted oxygen in waterways including the Chesapeake Bay.

The attorney listed for Borowicz, James Richard Theuer, didn’t immediately respond to requests for comment.

NASA spokesman Jeremy Eggers said in a statement that Borowicz hasn’t worked at Wallops since April 2018.
