Environmental Investigations and Remediation Services


Successful site closure requires a professional environmental team with diverse talents focused on the needs of the client. TechSolve has a proven ability to successfully conduct efficient investigations and implement practical solutions for remediation of contaminated sites.

Our approach to all projects involves the same degree of technical defensibility and project management accountability, whether it involves a single underground storage tank or a multi-million dollar remediation project. Our ongoing success in conducting investigations and remediation is based on many years of experience with a variety of site conditions and technologies. Following are a few examples of our remediation projects.

• Remedial actions include product recovery, soil excavation, natural attenuation, soil vapor extraction, and air sparging.

Wood Treatment Superfund Site, Bozeman, Montana
