Terracon's Minneapolis office opened its doors in 1988. The office started out providing environmental services and now provides a full range of geotechnical and construction materials engineering and testing, along with environmental consulting services. The office serves many national clients that are in Minnesota. They have also held a contract with the Minnesota Pollution Control Agency (MPCA) for 15 years to provide services on abandoned sites with environmental impacts that present a risk to human health and/or the environment. To date, the MPCA is the 3rd largest client for the company.
