Sulfate-Enhanced Bioremediation of BTEX

PROBLEM A former gas station in North Carolina contaminated groundwater with BTEX from a UST basin. The site is now in the median of a busy four-lane highway. Residents [...]

Using CoBupH™ to Adjust Aquifer pH

PROBLEM A US Government site had elevated TCE. Low aquifer pH stalled in situ bioremediation. PROJECT GOAL Inject organic substrate in the aquifer to enable naturally-occuring bacteria to effect in [...]

EOS® Permeable Reactive Barriers Treat Trichloroethene Plume

PROBLEM A large manufacturer in Indiana needed to remediate a long plume of TCE-contaminated groundwater, threatening a river almost 2 miles down-gradient of the source. PROJECT GOAL Cut off TCE migration [...]
