September 2026 Deadlines Are Approaching
The Question We Hear Most Often: "Am I Ready?"
For many facilities, the answer is not yet.
With compliance deadlines quickly approaching, now is the time to assess your readiness and ensure your facility has the processes, documentation, and controls necessary to meet New Jersey’s Legionella prevention requirements.
Protect Your Building. Protect Your Occupants. Protect Your Bottom Line.
What Is New Jersey S2188?
New Jersey S2188 (also known as A1970) is a state law signed on September 12, 2024, requiring covered facilities to establish and maintain a Water Safety Program to reduce the risk of Legionella bacteria in building water systems. The law followed a series of Legionnaires’ disease cases in Bergen, Passaic, and Mercer counties, and closely mirrors similar Legionella-prevention laws already enacted in New York City and New York State.
Rather than a one-time filing, S2188 requires an ongoing, documented program — testing, monitoring, control measures, and record retention — that facilities need to actively maintain and be able to demonstrate to regulators on request.
Key Requirements of NJ S2188
Covered facilities must establish and maintain a comprehensive Water Safety Program that includes:
- A written Water Safety Program with Legionella testing procedures
- System risk assessments to identify conditions that may promote Legionella growth
- Defined monitoring procedures
- Established control measures and critical limits
- Documented corrective actions when control limits are exceeded
- Response procedures and documentation for positive Legionella test results
- Program verification and validation activities
- Clearly defined responsible parties and staff responsibilities
- Reporting of positive Legionella findings to the New Jersey Department of Health (NJDOH), as required
- Documentation retention procedures
- Inspection readiness and compliance support
- Alignment with ASHRAE 188 requirements
- Five-year record retention
- Cooperation with public health outbreak investigations
Who Is Impacted?
NJ S2188 applies to a wide range of facilities and water systems, including:
Buildings with Aerosol-Producing Water Systems
- Cooling towers
- Evaporative condensers
- Decorative fountains
- Whirlpools and spas
- Misters
- Humidifiers
- Other aerosol-generating water features
Note: In many cases, Water Safety Programs may be developed specifically for these systems and may not require inclusion of the entire building water distribution system. Contact us if you are unsure.
Healthcare Facilities
- Hospitals
- Nursing homes
- Assisted living communities
- Senior housing facilities
Hospitality Properties
- Hotels
- Motels
- Casinos
Residential Buildings
- High-rise residential properties (6 or more stories) with centralized potable water systems

- Other covered water systems as determined by regulatory requirements
Frequently Asked Questions
What are the penalties for non-compliance with NJ S2188?
An owner or operator of a covered facility who fails to implement a required Water Management Plan can face a civil penalty of up to $2,000 for a first violation and up to $5,000 for a second or subsequent violation. Penalties can increase to as much as $10,000 for any violation that causes serious injury or death.
How is NJ S2188 different from New York's Legionella laws?
NJ S2188 closely mirrors the Legionella-prevention requirements already in place in New York City and New York State, following a similar framework of risk assessment, monitoring, documentation, and reporting — so facilities already familiar with NYC or NYS compliance will recognize much of the structure.
Does my facility need a Water Safety Program for the whole building or just certain systems?
In many cases, a Water Safety Program can be scoped specifically to aerosol-producing systems like cooling towers or decorative fountains, rather than the entire building’s water distribution system — but this depends on the facility type and its specific systems, so it’s worth confirming with a water safety specialist.
What should I do if my facility gets a positive Legionella test result?
NJ S2188 requires documented response procedures for positive test results, including reporting to the New Jersey Department of Health as required. Having these procedures defined and ready before a positive result occurs is a core part of compliance readiness.
Don't Wait Until It's Too Late
Regulators may expect evidence that your Water Safety Program is actively being:
Implemented
Monitored
Documented
Maintained
Facilities that delay preparation may face significant compliance challenges, increased liability exposure, and heightened risks to occupant health and safety.
