Environmental Response Laboratory Network (ERLN) Laboratory Requirements

The Environmental Response Laboratory Network requires its member labs follow specified quality systems, sample management, data reporting, and general, in order to ensure consistent analytical data of known and documented quality.

ERLN Water Focus Area

The Water Laboratory Alliance (WLA), within Environmental Response Laboratory Network, maintains analytical capability and capacity in the event of intentional and unintentional water contamination with chemical, biological and radiochemical contaminants.

Environmental Response Laboratory Network (ERLN) Data Submission Requirements

These Environmental Response Laboratory Network specifications are essential to the mission of providing consistent analytical data of know and documented quality for each Analytical Service Request (ASR).

Environmental Response Laboratory Network (ERLN) Basic Ordering Agreement Example

A BOA is a written instrument of understanding between EPA and a laboratory that contains terms and clauses applying to all future orders, a description of services to be provided, and methods for pricing, issuing, and delivering future orders.

ERLN Regional Support

Regional labs play important roles in the Environmental Response Laboratory Network. They can serve as point of contact; coordinate sample flow, special analytical service requests, or training exercises; and partner with regional emergency/disaster staff.

Environmental Response Laboratory Network (ERLN) Membership Policy

Covers laboratory affiliation, quality, data and information security, sample handling, reporting, and test methods for Environmental Response Laboratory Network members.
