Petroleum-impacted soil remediation


The Adventus Group is an applied environmental products company that provides various remediation biotechnologies – including those exclusive to our patent portfolio (see below). We are NOT consultants, and are geared towards supporting client project teams by providing unbiased design, support and selection of the most cost-effective remedial solution or strategy. As appropriate, our proven products may provide significant advantages. Implementation is subsequently provided by partnering with engineering and construction firms.

Our professional staff has over 150 cumulative years of experience in conducting remedial investigations/feasibility studies (RI/FS), remedial design, engineering and modeling (RD), remedial actions (RA) and implementation (support) at sites impacted by the total petroleum hydrocarbons (TPH) and polynuclear aromatic hydrocarbons (PAHs) typically found in petroleum-impacted soils. These projects have included industrial clients, federal, state and local governments, as well as public organizations. Useful knowledge and experience has been gained working at dry cleaner sites, manufacturing facilities, military facilities, landfills, bulk chemical storage facilities, active railroads and airports, Superfund sites, and as part of Brownfield site redevelopment efforts – while offering the following technologies and services:

For Groundwater

Slow release oxygen and nutrient support of indigenous aerobic bioremediation using EHC-Oor O-Sox, and/or in-well stripping using modified groundwater circulation wells (mGCW).

For DNAPL Stabilization

In situ geochemical stabilization (ISGS) of DNAPL to destroy contaminant mass, rapidly reduce the flux of CVOCs from stabilized DNAPL into the groundwater, and facilitate enhanced remediation of dissolved plumes.

For Soil Treatment

Ex situ, or in situ treatment of soil and sediment using:

  • Aerobic DARAMEND, which contains controlled release carbon and nutrients. This is typically used to treat PAHs, chlorophenols, and phthalates.
  • TERRAMEND, which contains controlled-release nutrients. This is typically used to treat TPH.

We have significant experience in the area of fate and transport modeling and litigation support.
