Several homeowners have had to rely on bottled water ever since a cancer-causing chemical was detected in nearly two dozen wells. Now, there's a push to get more wells tested.
"The situation up at Stony Hill has stabilized," said Gregory Bright, with Wake County Environmental Services. "EPA came in and did a really great job on getting a handle of the situation, how many wells are contaminated, started the process of trying to run water lines."
For now, affected homeowners are forced to rely on bottled water. The county is forced to face a daunting question.
"How big of a problem is this across the county? The truth is no one really knows," said Britt Stoddard, with Wake County Water Quality. "There is no single comprehensive database where one can look and see all of the sorts of things that could contaminate soil or groundwater."
Despite the uncertainty, officials say there's some good news. The contamination in the Stony Hill subdivision in Wake Forest seems to be confined.
Investigators say the only way to get to the bottom of the problem is for more homeowners to test their wells. They're encouraging concerned residents to drop off water samples at the county lab for testing.
Investigators told the commissioners that affected homeowners are mostly concerned about their health and their property values.
ABC11 has also learned that an estimated 2,500 sites could be contaminated.
