Unregulated Contaminant Monitoring Rule (UCMR3)

Anatek Labs, Inc. is approved by the EPA for the testing of drinking water under the UCMR3 program (Unregulated Contaminant Monitoring Regulation 3, Rule 3, or Phase 3). Anatek is approved for six UCMR3 methods. The methods are very demanding and include analysis by HPLC/MS/MS, GC/MS/MS, ICP-MS and ion chromotagraphy with detection limit requirements as low as 2 parts per trillion (ppt). Analysis for UCMR3 contaminants began in 2013 and will last for 3 years. Systems required to test will be notified by the EPA and/or their State.
