First Environmental Laboratories, Inc. is an independent environmental laboratory dedicated to providing industry, government, and consultants with timely and accurate chemical analyses.

Incorporated in 1993, and located in Naperville Illinois, First Environmental Laboratories Inc. was formed with a simple, yet extremely important objective:
To not only meet, but exceed the needs and expectations of both our customers and our employees.
As such, the company's management, organization, and recruitment policies all reflect this single operating philosophy.

Our emphasis is on establishing a one-on-one relationship with each of our customers. We accomplish this by identifying all project requirements prior to sample receipt, closely monitoring the project as it moves through the lab, and keeping you informed of the status of your project. Veteran project managers are always available to answer your questions and provide experienced technical support.
