Determining inorganic anions and disinfection byproducts (DBPs) in drinking water using ion chromatography is a key component of a comprehensive treatment and testing program that ensures public safety. The U.S. Environmental Protection Agency (US EPA) regulates water quality through the Safe Drinking Water Act (SDWA), which has set limits for the allowable concentration of contaminants based on their potential negative impacts on human health that can range from excess deposition in bones to increased infant mortality. DBPs, such as bromate and chlorite, can form as a consequence of the disinfection process and can be challenging to remove; therefore, monitoring these ions is extremely important to assure water safety and meet water regulations. The work presented here will demonstrate the determination of inorganic anions and oxyhalides in drinking water using US EPA Method 300.1. Data collection will be performed using a new, innovative ion chromatography system that utilizes automation and a more accessible, intuitive layout to simplify operation and increase consistency, reducing the amount of analyst interaction needed to achieve accurate and reproducible results.
