Remediation Engineering

TRC understands that effective site solutions rarely use a single “off-the-shelf” approach. It takes technical, regulatory, risk-management and financial considerations. That’s why we think like an owner when it comes to site remediation.

We provide the strategy to find cost-effective, efficient and sustainable solutions using state-of-the-art design models and innovative technologies, including natural source-zone depletion and in-situ remedies.

TRC can quickly delineate the extent of contamination using high-resolution tools and 3-D digital models. By developing robust conceptual site models, decision-makers gain confidence in approving the most cost-effective remedy.

Center of Research and Expertise (CORE)

TRC’s CORE is a national network of multidisciplinary teams of experts whose mission is to advance technical excellence.

Working on the forefront of emerging issues, the group promotes knowledge sharing and provides direct access to our experts.

CORE teams cover a wide range of focus areas that include vapor intrusion, advanced characterization and in-situ remediation, risk assessment, geotechnical engineering, chemical risk management and resiliency, and emerging contaminants.

Emerging Contaminants

TRC’s CORE teams provide site characterization, forensic, risk assessment and remediation services for emerging contaminants  such as per- and poly-fluoroalkyl substances (PFAS); microplastics; 6-PPD-quinone; 1,4-Dioxane; perchlorate; 1,2,3-Tricholorpropane and nanoparticles.

Our PFAS team has conducted original R&D on absorption, leachability, analytical protocols and forensic assessment.
