Utilities across the country are facing shifting water quality challenges — from changing influent chemistry to tightening discharge limits. This demands smarter monitoring and faster response. In this episode, Carlos Williams of Hach shares how utilities are adapting to this evolving landscape through advanced analysis and real-time data. He explains how rainfall patterns, conservation, and industrial variability can alter what flows into plants, requiring automated samplers and online instruments that catch contaminants early. Inside facilities, Williams highlights emerging treatment trends such as nutrient removal, energy efficiency, and diverse disinfection approaches that all depend on accurate water chemistry tracking. He also discusses how new discharge requirements are driving the need for continuous nutrient and solids monitoring to maintain compliance and protect ecosystems.
