|Remediated with Oxygenation|
A contaminated property in Salisbury, North Carolina, moves another step closer to being remediated and was recently declared “low risk” by the public relations officer for the North Carolina Department of Environment and Natural Resources Division of Waste Management (try saying that fast three times).
Nearby residents were advised that as long as they were using city water there was no reason for concern.
The site, at 1414 S. Fulton St., used to hold a gas station but that was many years ago. The ground has gasoline and diesel contamination as high as 8,170 ppm. Economic stimulus money is funding the cleanup process that entails excavation and the release of oxygenating compounds that begin breaking down the contaminats. Then, over time, the contamination will further break down through natural processes until it is below the regulatory limits. Oxygenation will also help to break down the petroleum in the groundwater.
Since 1992, when the contamination was discovered, six tanks have been removed from the property. The current owner knew about the tanks when he bought the land because the state had grandfathered them, making it unnecessary to remove them. But then 10 years ago the state offered to dispose of them and the owner agreed.
