Environmental Restoration

ERT performs all phases of investigation and remediation following RCRA, CERCLA, and other regulatory frameworks. This work has been performed under close coordination with Federal and state regulatory agencies including all 10 USEPA regions and 33 state agencies. Our support includes preliminary assessments, field sampling design and implementation, site characterization, remedial alternatives analysis, and removal/remedial activities, which, together, provides cradle-to-grave contaminated site assessment, cleanup, management, and closure. ERT has extensive experience planning efficient and complete analysis of a wide range of contaminants including:

  • Petroleum-based Contaminants
  • Solvents
  • PCBs and Pesticides
  • Chemical Warfare Materiel/Chemical Agents
  • Explosive Compounds and Propellants
  • Metals
  • Asbestos, Lead, and Mold

ERT utilizes both innovative and traditional sampling methods to assess complex sites covering industrial, residential, and commercial properties, as well as current and former federal facilities. ERT assesses contamination in a variety of ways on a site-by-site basis. Typical approaches include a wide array of drilling methods, soil vapor and air sampling, aquifer testing, soil/sediment/groundwater and pore water sampling, downhole geophysics, and a variety of field screening methods. We have successfully evaluated and implemented remedial designs including in-situ bioremediation, chemical oxidation, permeable reactive barriers, air sparge systems, and other pump and treat systems.

ERT makes use of mobile laboratories and real-time data analysis to guide further investigations, as well as NELAP accredited laboratory analysis with third-party data validation for all environmental media.

Case Study

Nike Missile Sites, MD and PA: As prime contractor to USACE, Baltimore District, ERT is performing $2.8M in firm, fixed price (FFP) CERCLA site investigations (SI), remedial investigations (RI), feasibility studies (FS) and remedial design (RD)/remedial action (RA) concurrently at five former Nike missile sites. Each has varying contaminants and unique geological complexities (e.g., karst and glacial geology). RAs included in situ bioremediation using hydrogen release compound and lead-contaminated soils removal. ERT worked closely with two state regulatory agencies and EPA Region 3 throughout this process, successfully closing three sites through direct negotiations.
