Requires DEP, DOH, owners or operators of certain public community water systems, and owners or operators of certain buildings or facilities to take certain actions to prevent and control cases of Legionnaires' disease.*

This bill (S 2188, now P.L.2024, c.66) requires large public water systems (serving over 100 connections and using surface or groundwater) and certain buildings to prevent Legionnaires' disease outbreaks. It mandates maintaining minimum disinfectant levels (0.3 mg/L chlorine or 1.0 mg/L chloramine) and creating annual maintenance plans to reduce Legionella bacteria risks. Water systems must report disruptions to the state within 72 hours and implement flushing, testing, and infrastructure upgrades. The state will create a public dashboard showing disruption reports and adopt rules for compliance, with penalties for violations like failing to meet disinfectant standards. The law directly affects water system operators and building owners, aiming to improve water safety through specific, measurable requirements.
