Property owner tried several different in-situ remediation technologies over the past 3 years without success, at a considerable cost
®Ivey-sol 106 pilot scale injection programbetween September 11 - 24, 2007Pump and treatment system installed andoperating with 3 inch Hg vacuumPilot scale results demonstrated significant ability to improve contaminant (DNAPL & LNAPL)mass recovery and potential to clean up the sitein a rapid and cost effective manner
Active chemical refinery (20 acre site)Several DNAPL (TCE chlorobenzene anddichlorobenzenes) and BTEX stored on-siteMultiple DNAPL and BTEX spill events reported over a site history extending back to the 1950sDNAPL and BTEX impacts to both the local soil and groundwater covering an 8 acre (+) areaRisk: potential risk for impacting the nearby municipal groundwater aquiferSoil comprised of glacial till, silt and silty sand
®“The in-situ application of the Ivey-sol surfactant technology significantly increased the DNAPL (>500%) and BTEX (>300%) mass recovery from the impacted soil and groundwater on-site. We were very pleased by these results leading to our recom-mending a full scale site application as a potentially rapid and cost effective method to achieve site clean up.”
