The Regional Laboratory System is an inter-dependent network of the ten regional laboratories of the United States Environmental Protection Agency (EPA). These laboratories provide the analytical, technical and programmatic support that is critical to accomplishing the Agency’s mission of protecting human health and the environment. The regional laboratories ensure that analytical and technical expertise are available at the regional level and are well positioned to rapidly address the ever changing needs of a variety of environmental programs and help meet state and local partners’ needs.

The EPA Regional Laboratories do not accept samples from the general public and the Regional Laboratories do not recommend or endorse commercial laboratories.
