FAQ

How does Criterion Labs support municipal utilities with Safe Drinking Water Act (SDWA) compliance?

Criterion Labs serves as a local, fully accredited environmental testing partner for Public Water Systems (PWS). We assist municipal authorities and water utilities in satisfying state DEP and EPA Safe Drinking Water Act requirements through routine analysis of: 

  • Microbiology: Total Coliform, E. coli, and Heterotrophic Plate Count (HPC). 
  • Inorganics & Metals: Lead and Copper Rule (LCR) compliance, nitrates, nitrites, and heavy metal sweeps (EPA 200.7). 
  • Organic Contaminants: VOCs, SOCs, Disinfection Byproducts (TTHMs and HAA5s), and PFAS matrices.

Yes. Criterion is one of the few Mid-Atlantic laboratories approved by the EPA for all three methods (200.7, 537.1, and 533) required under UCMR 5. This allows regional public water suppliers to meet federal monitoring mandates for 29 PFAS compounds and Lithium locally, avoiding the delays and risks of shipping samples to out-of-state facilities.
