New York Takes Action Against Legionnaires' Disease

In the wake of the recent and alarming outbreaks of Legionnaires' disease resulting in tragic fatalities in New York, state legislators are stepping up to implement crucial preventive measures. On October 20, 2025, Senator Cordell Cleare (D-Harlem), Chair of the Senate Aging Committee, and Assemblymember Linda B. Rosenthal (D/WF-Manhattan), Chair of the Assembly Housing Committee, announced legislation aimed at improving public health and ensuring the safety of New York's water systems. The bill, known as A.9095/S.8499, outlines a comprehensive approach designed to prevent future outbreaks of this serious disease, which is caused by the waterborne bacteria legionella.

Legionnaires' disease can be contracted when individuals inhale aerosols or aspirate water that contains legionella bacteria. This pathogen is not only common in natural bodies of water but is also often found in the plumbing systems of residential and commercial buildings. Potential sources of infection include showers, sinks, hot tubs, and cooling towers, making it critical to implement strict management and preventive measures in all water systems.

The current state regulations have been deemed insufficient to curb the growing spread of Legionnaires'. The severity of the recent outbreaks is underscored by the fact that seven people died and 114 individuals contracted the disease in Central Harlem alone this past summer. Additionally, outbreaks linked to plumbing systems have also been reported in Parkchester in the Bronx, and there has been a notable increase in cases across Westchester County including regions like Yonkers, White Plains, and New Rochelle. Alarmingly, New York consistently ranks among the top states for reported cases of Legionnaires' disease in the United States.

Senator Cleare emphasized the impact on vulnerable populations, stating, “Individuals with compromised immune systems, respiratory conditions, smokers, and the elderly are particularly at risk for Legionnaires' disease, which can lead to severe pneumonia and, in some cases, death. We must take proactive measures to safeguard public health and tackle the incidence of Legionnaires' disease through improved regulation and public education.”

Assemblymember Rosenthal echoed this sentiment, asserting that enhanced monitoring and awareness are crucial in preventing further loss of life. “Robust monitoring and increased public awareness can help spare families the devastating experience of losing loved ones to this lethal disease. The presence of Legionnaires' cases in various parts of the state indicates the urgent need for better oversight of our water quality,” she remarked.

Key Components of the New Legislation

The proposed legislation includes several pivotal measures aimed at tackling Legionnaires' disease effectively:

1. Water Treatment and Management: Public water system operators will be mandated to uphold specific levels of disinfectant residuals—specifically, maintaining at least 0.5 mg/L of free chlorine, alongside regular monitoring of water quality.
2. Public Notification: Water system operators will need to inform users about any planned or unplanned disruptions that could lead to increased legionella bacteria levels, detailing potential risks and recommended measures for exposure mitigation.
3. Building Water Management Plans: Building owners will be required to implement water management programs designed to minimize the risk of legionella in plumbing systems and water-using equipment, aligned with national standards set by ASHRAE and the CDC.
4. Case Investigation: The bill mandates thorough investigations into all reported cases of Legionnaires' disease, including testing the water sources in affected residences and workplaces.
5. Public Awareness Campaign: A public education initiative will be established to educate communities about the risks associated with legionella, prevention strategies, and symptoms to watch for.
6. Annual Reporting: An annual report will be compiled to summarize Legionnaires' disease cases, regulatory violations, and additional recommendations.
7. Fund Creation: A dedicated prevention fund will be established to collect fines from violations, which will support public awareness campaigns.

Gwen Hanlon, a victim's advocate who experienced the tragic loss of her husband to Legionnaires' disease, stated, “My children and I understand too well the pain caused by Legionnaires' disease. We lost my husband due to this illness while he was fighting cancer. It is vital that future families do not face the same heartache.” Hanlon emphasizes that proper water management throughout the community's drinking water system is critical in preventing such tragedies.

Moreover, the CDC reports that over 8,000 cases of Legionnaires' disease are documented annually in the U.S., with individual cases making up 96% of this number. In New York, the figures are troubling, with hundreds of incidents reported yearly, intensifying the urgency for systematic reforms. Furthermore, Erin Brockovich, a well-known environmental activist, recently reiterated the necessity for proactive measures to safeguard public health in her op-ed for the New York Daily News, calling for comprehensive water system management.

In conclusion, the new legislation aims to eliminate the recurring threat of Legionnaires' disease in New York, providing a pathway to not only prevent future outbreaks but also address ongoing individual cases, safeguarding the health of all New Yorkers.
