The most traditional method for soil remediation consists primarily of soil excavation and disposal to a landfill or a “dig and haul” scenario. GDSI has a close partnership with Laneco to ensure we have the inventory of heavy equipment needed to better serve clients in the completion of soil remediation projects.

GDSI specializes in hazardous waste management, removal and hazardous waste disposal of materials, including byproducts of both ongoing environmentally managed production environments, as well as the cleanup of contaminated sites. We provide full analyses and documentation to ensure clients remain compliant with local, state and federal regulations.


The proper locating, excavation, removal and disposal of underground storage tanks (USTs) involves the safe handling and destruction of the UST as well as proper record keeping. If not done properly, the process can be both dangerous and costly. This is why it should only be attempted by experts. 


GDSI offers extensive experience decommissioning and remediating USTs. Call us today to discuss your needs.
