UCMR 5 Analytical Chemistry Laboratory Services IDIQ

Provide analytical laboratory services supporting the fifth Unregulated Contaminant Monitoring Rule (UCMR 5). Once every five years, EPA issue a new list of unregulated contaminants to be monitored by public water systems. This Unregulated Contaminant Monitoring Rule (UCMR) requires systems to collect occurrence data for contaminants that may be present in drinking water but are not yet subject to EPA's drinking water standards set under SDWA. The UCMR 5 proposal outlines monitoring for 30 new chemical contaminants, consisting of 29 per- and polyfluoroalkyl substances (PFAS) and lithium between 2023 and 2025 using analytical methods developed by EPA and consensus organizations. Laboratories must successfully complete the UCMR 5 Laboratory Approval Program prior to analyzing UCMR 5 samples.
