Bedrock Application of ORC Advanced Allows for Site Closure
Case study highlights:
-
In situ remediation achieves 99% reduction of total TPH
-
ORC Advanced rapidly established aquifer conditions suitable for enhanced aerobic biodegradation of the contaminants of concern
-
Specially installed injection wells used to successfully address underlying fractured limestone bedrock

A former fuel service station site in Wiltshire, UK, was to be redeveloped as part of a major road construction project. The groundwater was impacted with total petroleum hydrocarbons (TPH), methyl tert-butyl ether (MTBE) and benzene, toluene, ethylbenzene and xylenes (BTEX) from leaking underground storage tanks (USTs). It was determined that remediation works were required at the site to eliminate the risk posed to human health and the environment, targeting elevated concentrations of TPH, MTBE and BTEX in the groundwater.
