The state has reached an agreement with an international company to clean up contaminated groundwater in Wake Forest.
Flextronics International USA has agreed to investigate and clean up the contamination in the Stony Hill Road community.
The first contaminated residential water well in the community was found in 2005 after a resident reported that his water had a petroleum smell. Tests found the solvents TCE and PCE. More polluted residential wells were found in 2012, according to the state.
The U.S. Environmental Protection Agency initially provided bottled water to residents with contaminated wells and installed carbon filtration systems on certain homes, the state said. In 2014, the EPA extended a water line from a community water system to serve the 22 homes where contamination was discovered in wells.
Repeated groundwater sampling conducted by the state since 2012 has shown that the contamination has not spread to other wells, according to the state Department of Environmental Quality.
The contamination is believed to be from two circuit board assembly companies that operated on the company site. Flextronics, which has its U.S. headquarters in California, did not cause the contamination, the state said in its statement. It bought the companies that had polluted the water.
The agreement between the state and the company is in draft form for 30 days before an administrative order is enacted.
Under the agreement, the state would have oversight over the company’s cleanup. According to the state, residents agreed to state oversight, rather than federal.
Flextronics would have to investigate the extent of the contamination. If more contaminated wells are found, the company would have to provide alternative water sources.
