EPA Posts Updated List of Laboratories Approved for UCMR3

EPA has recently posted on their website the list of laboratories that are approved for analyzing samples collected for the third Unregulated Contaminant Monitoring Rule (UCMR3). The list includes laboratory contact information and indicates which analytical methods are approved for each laboratory.  The laboratories met the UCMR 3 Laboratory Approval Program application and Proficiency Testing (PT) criteria for the methods indicated.  This approved laboratory list is subject to change.  Laboratories that withdraw or fail to maintain the method and program quality control requirements will be permanently removed from the list.

To access the list and find links to other UCMR3 information, go to EPA’s UCMR laboratory webpage.
