End of List

Large public water systems (PWSs) are required to use laboratories approved by EPA to analyze their
UCMR 5 samples (40 CFR 141.40(a)(4)(i)(H)). 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 5. The laboratories'
approval status indicates they have demonstrated specific capabilities using the designated method(s).

Large PWSs are responsible for their UCMR 5 results and must ensure that their laboratories are
following the methods and meeting the QA/QC criteria specified in UCMR 5. Laboratories must post
sample analytical results and required QC data electronically via the Safe Drinking Water Accession and
Review System (SDWARS) within 90 days of the sample collection date. EPA may revoke a laboratory's
UCMR 5 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 Once approval has been revoked, it cannot be reinstated during the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 5 monitoring period.
