Who We Serve


Industrial clients face compliance and liability challenges when residuals persist onsite or offsite after a cleanup. The impacted area can be one acre to 20,000 acres and may be located in an urban or rural setting. Terradex adapts LandWatch for one site or a portfolio of sites.

Utilities face the same challenges as our industrial clients but have the additional risk of sending field crews to sites where they can encounter contamination left by others. LandWatch is an indispensable tool for controlling contact with persistent residuals from former manufactured gas plants and other legacy sites. As part of a preconstruction screen, WhatsDown informs environmental and safety operations in the office or field about the utility’s own residuals and contamination from other sources.

State environmental agencies are charged with enforcing compliance of and facilitating public communication about contaminated sites or properties encumbered with land use controls. The agencies have portfolios of hundreds or thousands of sites, and DigClean is a compliance tool that scales to the agency’s challenges.
