The Environmental Protection Agency established the Environmental Response Laboratory Network (ERLN) to assist in addressing chemical, biological, and radiological threats during nationally significant incidents. The ERLN is a national network of laboratories that can be ramped up as needed to support large scale environmental responses by providing consistent analytical capabilities, capacities, and quality data in a systematic, coordinated response. The ERLN integrates capabilities of existing public sector laboratories with accredited private sector labs to support environmental responses.

ERLN's mission is to provide consistent analytical capabilities, capacities, and quality data to Federal, State, and local decision-makers. More about ERLN >>

Participation in the ERLN is based on a laboratory's ability to meet the ERLN's core requirements. More about membership >>

There are many benefits to ERLN membership including training and exercise opportunities, information sharing and technical support. More about benefits >>

Laboratories that analyze biological samples, chemical warfare agents, radiological, or toxic industrial chemical samples can join the ERLN.

Members of the ERLN make up a critical infrastructure that delivers data necessary for responses to large scale national emergencies. More about joining ERLN >>

The ERLN is focused on building capacity and capability in four primary areas. As an ERLN member your laboratory may have capabilities in one or more of these focus areas. Choose your focus area and learn more about what ERLN is doing to help build capacity and capability during an emergency.
