About Us

With a facility of over 26,000 square feet, and a highly educated and trained staff, we have the capabilities to assist mining companies, utilities, public agencies, mining consultants and engineers, environmental consultants, landowners, and water districts with their environmental testing needs. 

SVL was founded in 1972 by Wayne Sorensen. Wayne began with just a few instruments and staff, and the company quickly grew. For nearly 50 years, the clients of SVL have trusted us to provide analytical services to individuals and corporations to meet their compliance and research needs. 

When SVL began, the laboratory supported clients in mining exploration with fire assay and geochemical analysis. We processed thousands of drill-core samples in a full prep room of crushers and pulverizers (which we still utilize today). The lab also analyzed local blood lead samples and drinking water. As the mining exploration samples slowly dwindled in number, SVL transitioned into assisting clients more with comprehensive environmental testing services.

Our state-of-the-art lab is located in the center of one of the largest superfund sites in the United States, The Bunker Hill site. In 1987 SVL purchased the vacant Bunker Hill Mine research laboratory building and moved into its current location. Having a laboratory in the middle of such a significant site helps us to continue our mission of helping to provide services to clients that foster environmental sustainability. 

In 2017, ownership of the lab transferred to the second generation when Wayne’s daughter Nan Wilson took over the business. Nan literally grew up in the lab and continually looks to the future to grow SVL’s client base and ensure that SVL’s legacy of quality laboratory service continues.


SVL is an SBA certified HUBZone and WOSB entity and available to partner on award contracts.
