Drinking water is susceptible to numerous harmful contaminants, prompting the EPA to establish rigorous regulations for over 90 pollutants, encompassing 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. Our offerings include specific drinking water pH standards, as well as 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 and reliable laboratory analysis.
