EspañolSite Remediation Solutions Overview
Looking for some common sense information while wading through all the options? This section highlights some of the most popular site remediation solutions and highlights some key points about each one.
When it comes to contaminated site remediation and the treatment of soil, groundwater and vapor (air), there is a broad range of possible solutions to choose from. From in situ chemical oxidation (ISCO) and enhanced bioremediation to soil mixing and vapor intrusion barriers, there is no one-size-fits-all remediation solution.
Today, innovative treatment solutions are becoming increasingly more strategic allowing remediation practitioners to effectively target specific contaminant phases, types, concentrations and locations.

Vapor Intrusion Mitigation
Image #1 above illustrates several different types of problems that can occur in soil and groundwater at retail petroleum service station sites. These include underground storage tank (UST) source areas, on and off-site migrating plumes and resulting vapor intrusion impacts.
Image #2 above illustrates the implementation of several different remediation solutions at the same site including UST excavation and tank pit treatment, source area remediation, migrating plume cut-off and vapor intrusion mitigation using a physical
barrier.
Image #3 above illustrates several different types of problems that can occur at industrial sites where chlorinated solvents are widely used. These issues include source area contamination in soil and groundwater, on and off-site migrating plumes and resulting vapor intrusion impacts.
Image #4 above illustrates the implementation of several different remediation solutions at the same site including source area excavation and treatment, migrating plume cut-off as well as vapor intrusion mitigation using a physical barrier.
Real World Business Cases Where In Situ Remediation Saved Time and Money over Pump and Treat
When designing a remedial strategy, major decisions will be guided by the cost and performance of available technologies. Historically, options for groundwater treatment were limited to long-term and costly mechanical technologies such as pump and treat at many sites. But with new innovations in the environmental field, practitioners now have viable alternatives via in situ remediation that can both reduce costs and improve performance. This ebook features case studies of contaminated soil and groundwater sites where in situ was used to save money, as well as cost analyses evaluating the long-term financial impact of in situ approaches as opposed to pump and treat systems.
