PT Drinking Water Standards
Scheduled Proficiency Testing & PT Express™ for Drinking Water
Drinking water may contain many harmful contaminants, which is why the EPA has set standards for more than 90 pollutants, including microorganisms, inorganic chemicals, organic chemicals, disinfectants, and disinfection by-products.
We offer a wide range of Certified Reference Materials (CRMs) for drinking water analysis to ensure environmental and human health. Our offerings include testing standards for pH, residual free chlorine, turbidity, trace metals, mercury, fluoride, and nitrite.
