Environmental Response Laboratory Network (ERLN) provides federal, state, and local decision makers with reliable analytical data used to identify chemical, biological, and radiological contaminants collected in support of response and clean-up activities. ERLN goals include providing laboratory testing capability and capacity to meet the Environmental Protection Agency’s responsibilities for surveillance, response, decontamination, and recovery from incidents involving the release of chemical, biological, or radiological contaminants; facilitating the coordination of labs capable of responding efficiently and effectively to incidents; and establishing relationships and priorities with other federal laboratory networks.
