Soil & Groundwater Investigation & Remediation

Whether you need a full Remedial Investigation/Feasibility Study (RI/FS) and treatability study for an RCRA site or need to address an industrial or commercial release highway median spill, GEL Engineering is the partner you need. With our comprehensive soil and groundwater investigation and remediation services, we can help you address almost any environmental concern — as we have for other clients for more than 30 years.

Our client relationships span many years because we consistently deliver dependable solutions to environmentally complex issues.

GEL Engineering was the first consulting firm to receive approval in South Carolina for monitored natural attenuation (MNA) at an RCRA facility, and our soil and groundwater investigation and remediation services have been used at brownfields, CERCLA, RCRA, SUPERB, and other sites. That’s why we work with so many clients under on-call or indefinite delivery contracts.

Assessment, Remediation Design, Permitting, Installation, and O&M

After site assessment, GEL Engineering can evaluate the most cost effective soil and groundwater cleanup for your site conditions, install the system and operate and maintain the system until site closure.

Emergency Response

GEL Engineering can provide rapid response to most of your emergency environmental needs from spills to industrial hygiene issues.  Three offices allow for rapid response from a nearby office with the staff level to support the effort.

Groundwater Modeling

Experts proficient in the latest predictive computer modeling software such as Modflow use predictive modeling to model the fate and transport of contamination in soil and groundwater.

Landfill Permitting and Compliance

GEL Engineering can assist with permitting efforts related to new or expanded landfill projects, drawing upon our extensive agency contacts and reputation. We can also provide groundwater monitoring, closure and post-closure care plans, sampling and analysis plans, etc.

Groundwater Compliance Monitoring

GEL Engineering deploys dedicated field crews trained in the latest EPA SOPs for groundwater sampling, analysis and reporting for landfills, contaminated sites, RCRA sites, and CERCLA (Superfund) Sites.

Soil Gas Surveys

Constructing over contaminated areas can lead to contaminated vapors entering the building. GEL Engineering conducts state of the art soil gas surveys to evaluate risks and provide solutions.

Free Product Recovery

GEL Engineering has the equipment to safely remove free phase petroleum products from the groundwater table after a significant release, containerize it and manifest it for proper disposal.

Geologic Services

The GEL Engineering team offers a wide range of geologic knowledge and services, on both dry land and wetland and coastal zone environments.

UST Permitting and Release Assessment

Most underground storage tanks have leaked.  GEL Engineering has assessed and remediated hundreds of UST releases. The following list includes the steps in the regulatory process for USTs. After conducting each step, the site is either closed out or moves on to additional assessment phases. For more than 30 years, GEL Engineering has assessed, remediated and helped close petroleum contaminated sites.

Our UST permitting and release assessment services include:

• Site qualification assistance: GEL Engineering helps clients determine if they qualify for the SUPERB program, which allows for the reimbursement of some of a client’s assessment costs.
• Initial groundwater assessment: The first step in the UST assessment process that consists of one well and the collection of a soil and groundwater assessment.
• (Tier I): Additional investigation
• (Tier II): Comprehensive site evaluation
• Remediation evaluation/feasibility studies: This phase consists of selecting the remedial technology for site cleanup.
• Remediation system design, permitting, and implementation
• Remediation monitoring
• Site closure: This is the completion of the process in which the client receives a No Further Action Letter or Conditional No Further Action Letter.
