Soil and Groundwater Remediation

Soil and groundwater remediation is one of the primary focuses of PPM’s capability. PPM has completed hundreds of soil and groundwater remediation projects throughout the Southeast. Since much of the expenditures for environmental issues are related to remediation, PPM recognizes that this is the area that our clients’ costs can most significantly be reduced. Therefore, PPM has invested the time and resources to offer our clients the most innovative and cost-effective approaches available to bring their sites to expeditious closure. PPM has made substantial advances in implementing a wide range of remedial technologies from multiphase system installations to in situ chemical oxidation using ozone sparging. The soil and groundwater remediation experience of our staff encompasses Superfund sites, refineries, bulk fuel terminals, gas stations, chemical plants, and various commercial and industrial sites.


Services include: 

  • Remedial Alternative Evaluation/Technology Screening
  • Remedial / Corrective Action Plans
  • Remedial Construction Oversight
  • System Installation and Startup
  • Operations and Maintenance
  • Closure Monitoring


PPM has direct project experience with the following remedial technologies: 

  • Dual- Phase Vacuum Extraction

Project Highlight

PPM was retained by a petroleum distribution company to remediate a 100,000+ gallon gasoline release at a southeastern terminal. Due to the proximity of the release to a municipal well field, PPM expedited all site work, which included rapid delineation of the extent of impact;  pin-pointing and repair of the release source; design, fabrication, and installation of two Dual-Phase Vacuum Extraction (DPVE) systems for product recovery, a submersible pump system  (for hydraulic control), and an ozone sparge system. These efforts resulted in the recovery of an estimated 117,000 gallons of petroleum from the subsurface. A risk assessment was then completed to establish site-specific corrective action levels, and the site is now in the post-remediation monitoring phase.

Project Highlight

PPM was retained by an international company to delineate and remediate gasoline, diesel, oil, and light coal tar from soil and groundwater at a 10-acre bulk tank terminal location in a waterfront location. Closure assessments were conducted on the tanks; and site characterizations were completed in areas where spills, leaks, and buried steel bottoms from tanks were known to exist, as well as near the product lines and loading racks. Impacted soils were then excavated and landfarmed on site and remediated using  a thermal desorption unit. Enhanced product recovery was accomplished by stimulating the released product absorbed to sediment on the bottom of the excavation using rakes and compressed air; collecting floating product using skimmers and booms; and dewatering the excavation prior to backfilling. PPM’s on-site treatment approach allowed the treated soil to be returned to the excavated areas, saving our client an estimated $500,000. A risk assessment was then conducted to establish cleanup levels, and the site achieved regulatory closure from the governing environmental agency.

Project Highlight

PPM has been under contract to the Alabama Department of Environmental Management (ADEM) for over 17 years to  provide assessment and remediation services of orphaned underground storage tank (UST) sites in the state of Alabama.  Projects completed under this contract have included removal of underground storage tanks, excavation, transport and disposal of contaminated soil, delineation of petroleum releases into the soil and groundwater, recovery of free product, soil gas and vapor intrusion assessment, sampling for impact to public and private water supplies, performance of risk assessment to establish alternative corrective action levels, pilot testing, preparation of remedial action plans, installation of remediation systems, performance of operations and maintenance of remediation systems, and site closure and well abandonment activities.  To date, over 50 separate task orders have been issued to PPM under this contract.
