While grab sampling has served the industry for decades, continuous monitoring technologies offer substantial advantages in process control, compliance assurance, and operational efficiency. Understanding these benefits helps decision-makers evaluate the true value of continuous monitoring investments.<\/p>\n<p>According to the <strong>American Water Works Association (AWWA)<\/strong>, continuous chlorine monitoring adoption has increased by over <strong>40%<\/strong> in the past five years as utilities recognize the operational and compliance benefits. More than <strong>60%<\/strong> of systems serving populations over <strong>50,000<\/strong> now use continuous monitoring for critical disinfection control points.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_Real-Time_Process_Visibility\"><\/span>1.
