The fourth Unregulated Contaminant Monitoring Rule (UCMR 4) requires approximately 6,000 Public Water Supply systems to participate in monitoring for 30 chemical contaminants between 2018 and 2020 using newly developed analytical methods approved by EPA. This monitoring provides a basis for future regulatory actions to protect public health. Weck Laboratories has developed all of the required methods for compliance with the rule in-house and holds full approval from the Environmental Protection Agency. Over the last 15 years, Weck Laboratories has provided analytical support for all previous cycles of the monitoring rule: UCMR1, UCMR2 & UCMR3 including method development and holding a direct contract with USEPA for UCMR2 small systems.
