NYC Building Water Compliance Desk
One controlled record for every tower, sample and exception.
516Labs helps building owners, property managers and water-treatment teams coordinate recurring cooling-tower culture testing through qualified persons and ELAP-certified laboratories—then keeps dates, custody, results and corrective-action evidence tied to each system.

A recurring operating obligation
The 31-day clock changed the workload.
NYC requires Legionella culture sampling within 3–14 days after startup and at least once every 31 days while a cooling tower is operating. Sampling dates, results and triggered corrective actions create a chain of responsibilities—not a one-time test order.
31-day sampling calendar
Startup windows and recurring culture dates tracked by system, with accountable parties and escalation before a due date becomes an exception.
Qualified routing
Sampling is assigned to the qualified person or a sampler operating under that person’s guidance, with analysis routed only after relevant ELAP scope and service availability are confirmed.
Sample and custody controls
Collection details, chain of custody, pickup, laboratory receipt and exceptions remain tied to the correct tower and event.
Result threshold workflow
Results are preserved with the original laboratory report and routed to the responsible qualified person, owner and treatment team for required interpretation and action.
Inspection-ready record
Sampling dates, reports, custody records, documented actions and open exceptions assembled by system instead of scattered across vendors and inboxes.
Operating boundaries
Coordination without replacing the regulated parties.
The owner, qualified person, water-treatment team and performing laboratory retain their regulatory and professional responsibilities.

Program requirements change. Review the current NYC Health cooling-tower inspection and sampling guidance. 516Labs confirms the applicable pathway and participating providers for each building before service is awarded.
Portfolio workflow
Turn recurring dates into controlled events.
Start with the system inventory and the providers already in place. The desk can coordinate missing capacity without forcing replacement of a working incumbent.
Import the portfolio
Provide buildings, tower IDs, operating periods, current qualified persons, treatment firms, laboratories and recent sample dates.
Resolve gaps and ownership
Identify missing credentials, service areas, calendar dates, system records and escalation contacts before the next collection window.
Coordinate each sampling event
Confirm the responsible sampler, laboratory route, custody documents, pickup and receipt for the correct tower.
Close the evidence loop
Collect the original report, route results to responsible parties, log documented actions and keep unresolved exceptions visible.
Building water intake
Start with the portfolio you already operate.
List the buildings or systems, last known sampling dates and current providers. The desk will identify what still needs confirmation.
- Cooling-tower systems and operating periods
- Current qualified person, treatment firm and laboratory
- Registration IDs and next due dates
- Open results, actions or documentation gaps
Natural portfolio extension
Cooling towers first. Building water next.
After the recurring cooling-tower route is operating reliably, the same property record can support separate annual rooftop drinking-water tank inspections and bacteriological sampling, drinking-water investigations and other approved building-water programs.
