Lead Enters the Water After It Leaves the Treatment Plant
The Centers for Disease Control and Prevention (CDC) marks National Lead Poisoning Prevention Week October 25 to 31 this year, and drinking water sits on its list of ways lead gets into the body: water "contaminated by lead pipes or fixtures." The U.S. Environmental Protection Agency (EPA) sets its health goal for lead in drinking water at zero, because lead can harm people even at low exposure levels.
Most of that risk comes from the pipes and fixtures between the water main and the tap, not from the treatment plant. EPA's latest national infrastructure survey estimates about four million lead service lines are still in the ground. For a facilities manager, that puts the question inside your own walls: what is the water touching on its way to the break room?

Three Places Lead Hides in a Commercial Building
Lead gets into water when plumbing that contains it corrodes. EPA notes the problem gets worse where water is acidic or low in minerals. In most buildings, it comes from one of three places, and water that sits still makes each one worse.
The service line
The pipe that connects the building to the water main. If a building has a lead service line, EPA calls it the most significant source of lead in the water.
Solder on older pipes
Solder is the metal used to seal pipe joints. Lead solder was common in plumbing before 1986, so older copper lines can still carry it.
Brass faucets and fittings
In buildings without a lead service line, EPA says brass or chrome-plated brass faucets and fittings are the most common problem.
Water that sits still
Water that stands in pipes overnight or over a weekend has more time to pick up metal, which matters in offices and plants that close on weekends.
Plumbing installed after 1986 isn't automatically lead-free either. Today's federal "lead-free" standard allows up to a weighted average of 0.25% lead in pipes, fittings, and fixtures. The lead risks facilities managers should know about start with the age of the building and the history of its plumbing work.
The Federal Lead Pipe Timeline Runs Into the 2030s
In October 2024, EPA finalized the Lead and Copper Rule Improvements. The rule requires water systems to replace lead service lines within 10 years. That clock starts on the compliance date, November 1, 2027, so many systems have until the late 2030s to finish. The rule also lowers the lead "action level," the point where a utility has to act, from 15 parts per billion (ppb) to 10 ppb.
A water utility trade group is challenging the rule in federal court. According to the Natural Resources Defense Council (NRDC), which is defending the rule, oral arguments took place September 30, 2026, EPA has defended the rule so far, and a decision may take 6 to 12 months. The timeline could change.
Even on schedule, utility work covers the service line. Solder and fixtures inside a building stay the owner's responsibility.
| Lead source | Covered by utility replacement? | What the building can do |
|---|---|---|
| Lead service line | Yes, within 10 years of November 2027 | Ask the utility if the line is lead and when it's scheduled |
| Lead solder on interior pipes | No | Test at the tap; repipe or treat at the point of use |
| Brass faucets and fittings | No | Replace older fixtures; test drinking taps |
The water quality rules that apply to businesses explain where a utility's responsibility ends and a property owner's begins.
How a Facilities Manager Can Check a Building
A utility's annual water quality report covers the whole system. It can't tell you what comes out of a 1970s drinking fountain on the second floor. The CDC points to the local water authority as the first stop, and many public water systems will test drinking water on request.
- Ask about the service line. Utilities have to keep an inventory of service line materials. Ask whether yours is lead, galvanized, unknown, or replaced, and when work is planned.
- Test the taps people drink from. Break rooms, drinking fountains, and kitchen sinks matter more than a utility closet. Results can change with the time of day, the season, and how long water sat in the pipes, so one sample isn't the full picture.
- Use cold water for drinking and cooking. CDC advises against using hot tap water, which can carry more lead.
- Don't count on boiling. CDC says boiling will not reduce the amount of lead in water.
Very pleased with the purity of the water this machine produces & how easy it is to use! Simple, easy and tasty! Ice is a bonus too! Worked with Dillon and Casey with this install!

Bottleless Nation's team checks total dissolved solids (TDS), a measure of the minerals and other material dissolved in water, with a meter at every install and service visit. The basics of TDS in drinking water explain what that number tells you and what it doesn't. A TDS reading isn't a lead test, so lead still needs its own lab test.
Where Point-of-Use Purification Fits
Replacing every pipe and fixture in an older building can take years and a large budget. Point-of-use purification works at the spot where people fill a cup. It purifies water after it has passed through the building's plumbing, which is where lead gets picked up.
CDC's guidance for people concerned about lead is a point-of-use system certified by an independent testing organization to NSF/ANSI standard 53 for lead. Before you choose any system, ask the vendor which contaminants its certification covers.
Reverse osmosis pushes water through a membrane so fine most contaminants can't get through. Bottleless Nation's S1, S3, and M6 run four or five purification stages, with reverse osmosis at the center, plus an in-tank UV LED light that keeps stored water sanitized. They're certified to NSF/ANSI 58 for reverse osmosis and NSF/ANSI 55 for UV. The guide to how reverse osmosis works for business drinking water covers the process stage by stage.
Each unit connects to the building's water line, so there are no jugs to store or reorder. Installation is included at no extra charge, and so are service calls. Bottleless Nation's team handles the annual preventative maintenance and the annual filter change. Used filters from most systems are often thrown away. Bottleless Nation sends the ones its team pulls to Reworld for thermal destruction instead.
For years, our store has relied on bottled water, and I was initially hesitant about making a change. Our building is older, and I anticipated significant issues with plumbing new lines to the exact location where we needed the dispenser. However, the entire process was flawless … Chad's install team completed the work seamlessly in about an hour.

Use Lead Poisoning Prevention Week to Check Your Building
The week is a reminder to get answers before the federal timeline does. Ask the utility about your service line, test the taps people drink from, and decide where purified water should go first. Bottleless Nation serves businesses in 33 markets nationwide and can build a setup for nearly any kind of building, from a single break room to a plant floor.

Frequently Asked Questions
When is National Lead Poisoning Prevention Week?
The CDC holds it every October. In 2026 it runs October 25 to 31, with the theme "Keep Kids Safe from Lead."
Can a newer building still have lead in its water?
Yes. Buildings older than 1986 carry the most risk, but brass fixtures and the service line from the street can add lead to water in newer buildings too. Testing at the tap is the only way to know.
Does the utility replace lead pipes inside my building?
No. Federal replacement rules cover the service line that connects a building to the water main. Pipes, solder, and fixtures inside the building are the owner's responsibility.
How does a bottleless water cooler get its water?
It connects to the building's existing water line and purifies the water at the unit, so it delivers purified water without jugs or deliveries.
Who maintains the system after it's installed?
Bottleless Nation's team handles annual preventative maintenance and the annual filter change, and service calls come at no extra charge.
Does Bottleless Nation serve my area?
Bottleless Nation serves 33 markets across the U.S. The all-locations page lists each one, and the team can confirm coverage for your address.
