Certified Reference Materials for Drinking Water Analysis

Drinking water is susceptible to numerous harmful contaminants, prompting the EPA to establish rigorous regulations for more than 90 pollutants, including microorganisms, inorganic chemicals, organic chemicals, disinfectants, and disinfection by-products.

We provide an extensive range of certified reference materials (CRMs) tailored for comprehensive drinking water analysis. Offerings include drinking water pH standards and testing standards for residual free chlorine, turbidity, trace metals, mercury, fluoride, and nitrite.

Our drinking water standards are essential for maintaining water quality, safeguarding public health, and supporting accurate, reliable laboratory analysis.
