Geocon has been under contract with Caltrans since 1994 to perform site investigation and remedial evaluation services and site closure activities throughout California. We have provided services on over twenty various master contracts on a task order delivery basis (more than 4,000 task orders). Geocon has also provided on- call emergency hazardous substance removal and disposal services for construction and demolition projects responding within 30 after receiving emergency work requests.

Geocon has provided initial site assessments (ISAs), aerially deposited lead (ADL) site investigations, asbestos and lead-based paint building and bridge survey programs, hazardous waste remedial excavations for ADL impacted soil and underground storage tank (UST) site investigations.

“From my experience it’s been rare to receive the type of customer service, interest, positivity and quality of work you’ve provided.”
