EPA 533 included under new UCMR 5 PFAS Rules

York Analytical has received a stream of inquiries recently about analytical capabilities now required by the EPA  — or will beginning in January 2023 — under the new UCMR 5 PFAS monitoring rules.

  • In August, York attained its potable water certification for EPA 533 in New York with New Jersey and Connecticut pending.
  • York is certified to analyze drinking water samples by EPA 537 and EPA 537.1 in New York and Connecticut.
  • For groundwater and soil matrices we employ EPA 537M, a modification which employs isotope dilution that the NYSDEC requires for all regulated projects.
  • NYSDEC will mandate the use of EPA (draft) 1633 for soil and non-potable water as of November 1, 2022.  York will have this analytical capability in place prior.
