CHESAPEAKE, Va. (WVEC) -- The preliminary results are in, and the findings are concerning, but not as widespread as initially feared.

From Feb. 3 to Feb. 13, the Navy tested the drinking water in 52 homes near Naval Auxiliary Field Fentress, and found traces of the contaminant known as "PFC's" in two of them.

Sharon Brown has lived directly next door to the auxiliary landing field for ten years. She says the noise is bad enough. Now, this.

"I'm just really frustrated," she said. "I mean, they knew 30 years ago it was possible contamination."

Now, Brown wants to know if her well is one of the ones affected. So far, she says she's heard nothing.

"I've called all my friends, texted all my friends, they say they haven't heard either," she said.

In fact, the Navy has begun providing bottled water to the two properties in question, which have not been publicly identified.

Naval Air Station Oceana's commanding officer says the test results at this point are "un-validated," and it will be about two more weeks before the findings are conclusive, at which time the Navy will hold another open house for local residents.

"I'm pleaded with great collaboration efforts we've shown with the federal agencies, the state agencies, the city of Chesapeake and our Navy team," said Captain Lou Schager. "I think the proactive nature with which we're handling this is providing a transparency that's very important."

Now, Virginia Senators Tim Kaine and Mark Warner are getting involved. They've sent a letter to Navy Secretary Ray Mabus seeking a briefing on lab reports and information about any additional testing planned.

They wrote that when it comes to protecting service members and the surrounding community, government has a "moral obligation to ensure their health and welfare."

Scientists are not sure about the possible health effects of human exposure to PFCs. For the most part, studies have found that animals exposed to them at high levels have shown changes in the function of the liver, thyroid, pancreas, and hormone levels.
