Rapid Response and Remediation for Gasoline Pipeline Release: Ohio River, KY

The situation: An undetected breach in an underground gasoline pipeline resulted in the release of more than 200,000 gallons of gasoline to a shallow aquifer. Dispersion of the gasoline plume was resulting in seepage of gasoline to the nearby Ohio River, a major waterway under U.S. Coast Guard jurisdiction. In addition, a deeper aquifer used by the local municipality as the public water supply for approximately 100,000 customers was under threat of groundwater contamination from the gasoline release. . .

Swamp-Assisted Remediation by Natural Attenuation: Rocky Mount, NC

The Situation:
A former surface impoundment for electroplating sludge at a metals manufacturing facility resulted in an elongated plume of dissolved chlorinated hydrocarbon compounds, including 1,1,1-TCA, 1,1-DCA, and 1,1-DCE, extending from the former surface impoundment to a downgradient swamp approximately ½ mile away, which serves as a reservoir of water that trickles into a series of [...]
