Dirty Dirt: The hazards of soil pollution, and what to do about it

SoilcontamSoil pollution is the build-up of toxic substances in concentrations high enough to be hazardous to human health, wildlife and the natural ecosystem. Contaminated soil can have serious health effects on humans, as well as the environment.

Health effects on humans include organ damage, increased risk of cancer, and bioaccumulation, or the transfer of pollution throughout the food chain. Regular monitoring of soil quality can help prevent exposure to dangerous contaminants.

But what do you do if you think your soil might be polluted? EFS provides complete and innovative remediation services for addressing contaminated sites. Our remediation services include: demolition, excavation, transportation and disposal of contaminated soil, construction and installation of in-situ remediation systems, and more.

#DidYouKnow EFS has experience working on Superfund Sites

Excavator Blue Sky#DidYouKnow that EFS has experience working on dozens of Superfund Sites across the United States?  Below is an example of a Superfund Site where EFS performed work in recent years.

Environmental Field Services, Inc. (EFS) was contracted by a client to provide soil mixing services for the site located in Ashippun, Wisconsin.

Prior remediation efforts consisting of a groundwater pump and treat system operated at the site until 2004. An amendment to the Record of Decision (ROD) modified the treatment strategy to excavation or in-situ treatment of hot spot areas in order to meet the remedial action objectives for the site in a shorter time period.  In – situ treatment was selected as the remedy and this phase of work focused on five specific “hot spot” source areas containing elevated concentrations of trichloroethylene (TCE) in soil and groundwater.

Initial site activities included the establishment of staging and laydown areas, and installation of erosion control measures.   Following set up, EFS excavated and stockpiled 215 cubic yards of clean topsoil and 1,160 cubic yards of overburden soils to access the treatment intervals.

Soil mixing was performed to promote in situ chemical reduction through biotic and abiotic degradation mechanisms with the addition of Daramend®, a proprietary products that consists of a soluble substrate and zero valent iron (ZVI).  Daramend® was delivered in bulk and blended on site and delivered to the targeted treatment intervals using an excavator mounted dual axis mixing tool to depths of up to 18 feet below grade.  Post mixing verification sampling confirmed the achievement of design mix ratios in each of the treatment cells.  Geotextile fabric was installed and each treatment cell was backfilled to grade with the overburden soils and topsoil.  Following topsoil placement, each area was reseeded to promote site restoration.

Industry Experience – Industrial Decontamination Services – Kenosha, Wisconsin

DecontaminationTo date, EFS has completed approximately 4,000 environmental projects ranging from direct push sampling to facility decommissioning and demolition. Below is a case study on one of their previous projects.

EFS was contracted to perform industrial decontamination services in Kenosha, Wisconsin. The project was performed in conjunction with the Voluntary Party Liability Exemption (VPLE) process for the site. EFS was retained to perform aboveground storage tank (AST) cleaning and removal; annealing furnace removal; dismantling of electropolishing equipment; wastewater treatment pit demolition and removal; and concrete floor removal and replacement.

The scope of services provided by EFS included:

  • Preparing a site specific Health and Safety Plan.
  • Cleaning, removing and disposal of six ASTs and associated piping, dismantling and removal of annealing furnace and all associated ancillary equipment.
  • Purging, cleaning, removal and off-site recycling of a 10,000 gallon anhydrous ammonia tank.
  • Dismantling, removal and loading of all facility electropolishing equipment classified as D007 hazardous waste.
  • Demolition, removal and loading of three underground concrete wastewater treatment pits associated with the electropolishing process.
  • Saw cutting, removal and replacement of 4,500 square feet of 8-inch thick concrete flooring, including epoxy coating.
  • Assisting with the collection of confirmatory soil samples, decontamination, backfilling and concrete capping of five underground pits located throughout the facility.
  • Excavation and loading of 150 tons of impacted sediment material from an on-site drainage ditch.
  • Grouting and capping 300 linear feet of underground air ducts.

All work activities are performed in strict accordance with the Occupational Safety and Health Administration (OSHA), Wisconsin Department of Natural Resources requirements. EFS utilized a Wisconsin-Certified Tank Cleaner-Remover and experienced heavy equipment operators to perform the work. EFS also completed and submitted all required Wisconsin Department of Natural Resources documents associated with the tank cleaning and removal activities. All work was performed on schedule and under budget within a four week period.
