• Total Petroleum Hydrocarbons and BTEX contamination, up to approx. 10,000 mg/kg
• Topical application of PetroFix onto the excavation base and sides to prevent the occurrence of recontamination
• The combination of sorption and biological degradation results in long term protection of the pipeline and avoidance of potential contaminant migration into and along the pipe bedding
• Results: Monitoring showed that there was 94% less petroleum hydrocarbons in MW-1 compared to MW-2

A new underground pipeline was required to be installed across a complex chemical plant in southwestern Germany. It was found that part of the pipeline would intersect an area of soil and groundwater impacted with petroleum hydrocarbons and BTEX compounds.
