Environmental response laboratory network (ERLN)
EPA established the Environmental Response Laboratory Network (ERLN) to assist in addressing chemical, biological, and radiological threats during nationally significant incidents. The ERLN is managed by EPA’s Office of Emergency Management and serves as a national network of laboratories that can be accessed as needed to support large scale environmental responses by providing consistent analytical capabilities, capacities, and quality data in a systematic, coordinated response. Public laboratories play an invaluable role in the network given their existing relationships with federal, state, and local decision-makers, and political leadership. As ERLN members, public laboratories may be responsible for providing analytical data or performing quality assurance/quality control functions.
