This case study reviews an active gas station in Nebraska that was adversely impacted by a dissolved‑phase, hydrocarbon plume. The treatment solution from REGENESIS was successful in reducing the concentrations of BTEX, TPH-G, and MTBE to non-detect levels. REGENESIS conducted a thorough and innovative DVT program prior to remediation in order to ensure an effective remedial design. They used the DVT to produce a design which fit the precise needs of the site as well as the client’s budget. After the successful treatment, the consultant continued to monitor the groundwater trends until the Nebraska Department of Environment and Energy (NDEE) granted the site closure status. The on-site gas station has remained open for business.

Nebraska case study

Case study highlights:

  • Thorough Design Verification Testing (DVT) program helped to create a unique design for effectively treating the contaminant plume.
  • Cost-effective design and application required a single application event.
  • The remedial approach successfully treated a 200 ft. long dissolved phase hydrocarbon plume within the first 50 days.
