How do you participate in green practices?

Geotechnology’s environmental commitment is evident through our “green” practices both personal and business. Some noteworthy facts about our environmentally consciousness business practices are:

  • We recycle approximately 192 cubic yards of metal from Shelby tubes and other sampling or laboratory supplies per year.
  • As a standard service, we provide environmental services to help clients meet and excel compliance and clean-up standards. Examples include Brownfields, Voluntary Cleanup Program, EPA, compliance, permits, natural systems, environmental site assessments and monitoring.
