Remediation of Soil and Groundwater

LNAPL Impacted Groundwater

LNAPL Impacted Groundwater

We remediate chemically impacted soil and groundwater using a wide range of in-situ and ex-situ technologies. Our focus is to design, build, operate and support systems that are environmentally friendly, reliable, unobtrusive, and effective in restoring sites impacted by regulated and emerging contaminants. These include, but are not limited to: volatile organic compounds (VOCs) such as tetrachloroethylene (PCE), trichloroethylene (TCE), 1,2,3-TCP; gasoline range organics (GROs or TPH-g) such as benzene, toluene ethylbenzene, xylenes (BTEX); diesel range organics (DROs or TPH-d); oxygenates and degradation byproducts such as MtBE and TBA; light non-aqueous phase liquid (LNAPL); metals including hexavalent chrome, arsenic and selenium; n-nitrosodimethylamnie (NDMA) and 1,4-dioxane, and ;inorganic compounds such as nitrates and perchlorate.

During remediation, we implement monitoring plans to monitor effectiveness, human health risks, the environment, and support regulatory closure. We support site remediation through the following:

  • Site Monitoring and Investigation
  • Feasibility Studies
  • Remedial Action Plans
  • Remediation System Design and Permitting
  • Remediation System Construction
  • Operator Training
  • System Operation and Maintenance
  • Regulatory Support throughout Remediation
  • Regulatory Site Closure
  • Monitored Natural Attenuation

We have executed a wide range of projects are we have designed and operated remediation systems that include: excavation and disposal/recycle, soil vapor extraction, air sparge, oxidation, advanced oxidation, chemical metering systems, liquid phase activated carbon systems, vapor phase activated carbon systems among many other technologies.
