Remediation & Engineering Design
THG and Associates conducts engineering design for turnkey environmental assessment and remediation projects as well as
specialty engineering applications. THG design teams are selected for each project based on the objective of overall
design effectiveness and cost efficiency.
Remedial Design
Air, soil and groundwater remediation is routinely conducted to reduce contaminant concentrations at RCRA, CERCLA and UST spill and release sites.
THG’s remedial design background covers the complete spectrum of treatment technologies both in-situ and ex-situ. These include the following:
Vacuum Extraction and Treatment
Interceptor Walls and Trenches
Soil Venting
Enhanced Bioremediation
Vapor containment / treatment
Geologic / membrane caps and liners
Facility Design
THG conducts a wide variety of industrial facility design and operating specifications. Whether the work is a response to regulatory
compliance requirements or production enhancement, THG provides the most efficient design and operations specifications.
Examples of this work include the following:
UST system upgrade and replacement
Sump design and certification
Filtration systems
Stormwater drainage systems
Waste containment and permitting
