In 1994, our founders, wanted to change the way field services for consultants and engineers was performed. Driven by bold vision and a strong entrepreneurial spirit, they were committed to finding permanent solutions for any environmental problem. Thus, Environmental Field Services was created.

EFS works to transform environmental consultants’ and engineers’ plans into reality.

We implement our clients’ designs in all phases of environmental field work, including remedial construction, injections, operations & maintenance, and other field related services.

Today, EFS is a nationally recognized environmental contracting firm. We specialize in injections, remedial construction, and field services to a wide range of clients, including 50 of the ENR’s Top 200 Environmental Firms. With our continued commitment to our employees and clients, our company has stayed true to the mission statement that was created over 25 years ago, “provide superior service to clients and an unwavering commitment to employees.”
