Organic, Inorganic, Microbiology & PT Reference Materials for Drinking Water Testing

Drinking water may contain many harmful contaminants which is why the EPA has set standards for over 90 pollutants including microorganisms, inorganic chemicals, organic chemicals, disinfectants, and disinfection by-products. We offer a wide range of Certified Reference Materials (CRMs) for testing applications for your drinking water analysis to ensure environmental and human health. Some of our offerings include testing standards for pH, residual free chlorine, turbidity, trace metals, mercury, fluoride, and nitrite.
