At the former fire training area of the Sundsvall‑Timrå Airport in Sweden, SourceStop® Liquid proved highly effective in reducing PFAS migration from a heavily contaminated source zone. Up to 99.8%…
The remediation of CrVI using 3-D Microemulsion allowed for effective source treatment and plume control, even under complex hydrogeologic and site-access conditions 3-D Microemulsion not only met cleanup objectives onsite…
Successful installation of a 230 ft PlumeStop® barrier to prevent further migration of PFAS, as part of Swedish government-funded study. PFAS concentrations reduced by 97% to 99% downgradient of the…
Hydrocarbon contaminants reduced below target levels, in regulatory review for site closure The barrier has stopped the offsite migration of a petroleum hydrocarbon plume onto a public road and archeological…
Combined ERD/ISCR treatment has achieved the site’s remedial objectives rapidly and cost-effectively, allowing the site redevelopment to continue Lines of evidence suggested high rates of dechlorination continued to occur and…
>99% decrease in groundwater PFAS concentrations SourceStop has established a new equilibrium in the treatment zone, reflecting a high degree of controlled PFAS adsorption, with almost no dissolved phase PFAS…
SourceStop® Liquid, a colloidal activated carbon (CAC), was applied as a permeable sorptive barrier to reduce PFAS migration hydraulically. The permeable sorptive barrier was designed and implemented downstream of the…
In situ remediation of groundwater contaminated with Trichloroethylene (TCE) was chosen for a former fur factory in Svenljunga, Sweden, as excavation or thermal treatment was deemed too expensive. A targeted…
A large-scale remediation project with challenging conditions: geology, underground services, ongoing site use and multiple stakeholders Treatment of a co-mingled chromium (VI) and TCE plume via enhanced biological dechlorination and…
