Drinking Water

Eurofins has the two largest drinking water testing laboratories in the United States and serves the potable water quality industry and communities throughout the United States and in more than 100 countries worldwide.  Our experience profile demonstrates that we are the undisputed market leader in drinking water analysis. Eurofins’ two potable water testing laboratories (Pomona, CA and South Bend, IN) serve more than 7,000 municipalities as well as bottlers, engineering firms and consultants, state governments, and federal agencies such as the EPA and U.S. Military.  Our PFAS testing services include EPA 537.1 and EPA 533.

Highlights to our drinking water success include:

• EPA contractor for UCMR1 (2001-05), UCMR2 (2008-10), UCMR3 (2013-2015), and UCMR5 (2023-2025)
• Federal contract laboratory for USGS, USBR and US Armed Forces
• State contract laboratory for AR, AS, AZ, DE, GU, ID, MN, MS, NJ, NV and UT
• PFAS EPA Method validator for EPA 537 and EPA 533

The Eurofins drinking water labs have been analyzing PFAS for over 20 years which includes the initial EPA PFAS data collection and analysis when the two labs provided roughly 40% of US Method 537 analyses during the Third Unregulated Monitoring Rule (UCMR3). Existing national occurrence data for PFOS, PFOA and other PFAS are based on results from EPA’s UCMR3 program, a national data gathering effort of public water systems in 2013-15.

Both laboratories have been audited and accredited by EPA in support of special regulatory programs (TNI, ICR, UCMR, SWDA and LT2) in the last 20 years. We strive to educate ourselves and provide as much knowledge as we support our clients. We collaborate with EPA on analytical methods, detection limit feasibility relative to proposed regulatory thresholds, best practices and acceptable precision & accuracy. This firsthand collaboration and interaction directly with regulators helps us stay abreast of the priorities for future regulations of emerging contaminants.
