About Us

GeoSierra Environmental concentrates on technology-driven services for soil and groundwater remediation to expedite site closure strategies. While we are capable of providing turnkey projects ranging from limited site-specific investigation activities to design and build, we also participate in teaming arrangements with other solution providers, as we recognize the added value such arrangements can often bring to a project. GeoSierra Environmental has been successful in modifying soil and groundwater remedies to save costs, eliminate O&M, and reduce the time to site closure.


At GeoSierra Environmental, our goal is to provide safe, responsive, technically superior, and cost-effective solutions to address our client’s complex environmental concerns. Our team of dedicated environmental professionals have solid technical, mechanical, and geotechnical credentials, and consistently meet or exceed our clients’ expectations.
