Eurofins Eaton Analytical is subject to pre-scheduled and unannounced audits by regulators and other 3rd parties as frequently as every year. In contrast, most laboratories are audited by the same regulatory agency every 2-3 years.

In the last few years, representative audits at our facilities have been conducted by:

  • ACLASS (for ISO 17025 Accreditation)
  • California Water Service Company
  • CH2M-WG Idaho, LLC
  • Coca Cola Corporation
  • The State of Arizona DHS
  • The State of California DPH (TNI and ELAP)
  • The State of Florida NELAC
  • The State of Indiana
  • The State of Kentucky DEP (LT2)
  • The State of Massachusetts DEP
  • The State of New Jersey DEP
  • The State of South Carolina
  • U.S. Bureau of Reclamation
  • U.S. EPA (UCMR3 and Regulation 10)
  • U.S. Navy

We also participate in the EPA Water Supply and Water Pollution Proficiency Testing (PT) programs and we use an internal blind performance evaluation sample program to monitor our technical operation and to verify proficiency of all analysts. Eurofins Eaton Analytical has also served as a referee laboratory for commercial producers of external reference samples as well as for the U.S. EPA in the verification of their test methods.
