Large public water systems (PWSs) are required to use laboratories approved by EPA to analyze their UCMR 4 samples. EPA will arrange for
samples from small PWSs to be analyzed by approved laboratories under contract to the agency. Laboratory participation in the approval
program is voluntary, and is specific to laboratories analyzing samples for UCMR 4. The laboratories' approval status indicates they have
demonstrated specific capabilities using the designated method(s).
PWSs are responsible for their UCMR 4 results, and must ensure that their laboratories are following the methods and meeting the quality
assurance/quality control (QA/QC) criteria specified in UCMR 4. Laboratories must post sample analytical results and required QC data
electronically via the Safe Drinking Water Accession and Review System (SDWARS) within 120 days of the sample collection date. EPA may
revoke a laboratory's UCMR 4 approval status if the laboratory does not adhere to QA/QC procedures and criteria, or fails to post data to
SDWARS in a timely and accurate manner. If EPA revokes approval, the laboratory's name will no longer appear on this list. Once approval
has been revoked, it cannot be reinstated during the UCMR 4 monitoring period.
Please send questions to: UCMR_Lab_Approval@epa.gov
