Does a Home Daycare Need to Test Its Drinking Water for Lead?

If you've already dealt with the lead-paint question for your licensing file, it's easy to assume you've covered "lead" and move on. You haven't — not entirely. Lead paint and lead in drinking water are two different exposure pathways with two different causes, two different tests, and in many states, two different rules. A home can pass one and still have a problem with the other.

Water-borne lead doesn't come from paint at all. It leaches into your tap water from old lead pipes, lead solder joining copper pipes (common in homes plumbed before 1986), or brass fixtures and faucets that contain small amounts of lead — even in homes with no lead paint anywhere in sight. Because young children absorb lead more readily than adults and are more vulnerable to its effects on development, this is exactly the kind of hazard that shows up on child care licensing radar, separately from paint.

What the EPA says, and what your state actually requires

The EPA has issued specific guidance and rulemaking directed at lead in drinking water in schools and child care facilities, including sample-collection guidance for testing at the tap. But EPA guidance and a state licensing requirement are not the same thing. Whether you, as a home-based provider, are required to test your water and report the result to a licensing agency depends on your state.

Some states — particularly those with a lot of older housing stock, older plumbing, or a documented history of lead service lines — have built water lead testing into their licensed child care facility rules, sometimes specifically flagging facilities on well water or in homes built before lead solder was phased out. Other states leave it as a recommendation rather than a requirement, or don't address it in child care licensing at all. Requirements differ on frequency too — anywhere from a one-time test to periodic retesting tied to your license renewal — and on which taps you're expected to sample (every fixture used for drinking, cooking, or mixing formula, versus a single representative outlet).

Because this genuinely varies by state, don't assume either answer. Confirm with your state's child care licensing agency whether water lead testing applies to your home, and check the home daycare licensing hub as your starting point for narrowing that down. If you're on a private well rather than municipal water, that's worth flagging specifically when you ask — well water sometimes triggers different or additional expectations than a municipal supply.

How the testing actually works

• Water testing kit. Widely available online or through a local hardware store; you collect a sample from your tap following the kit's instructions (often a "first draw" sample taken after the water has sat in the pipes for several hours, since that's when lead concentration is typically highest) and mail it to a lab.
• Certified lab test. Some states specify that the sample has to go through a state-certified lab rather than a mail-in consumer kit — check before you buy a kit, so you're not paying for a test your state won't accept.
• Multiple sample points. If your state requires testing "all outlets used for drinking, cooking, or formula," that likely means every kitchen and bathroom tap kids or you use for that purpose, not just one.

Keep the dated result with your other facility records — the same file a licensor would ask to see during an inspection.

What to do if lead shows up in your water

If a test comes back with a lead level above the threshold your state (or the EPA guidance) uses to flag a concern, you have two realistic paths, and which one makes sense depends on the source of the lead:

1. A filter certified for lead removal — a faucet-mounted or pitcher filter certified to NSF/ANSI Standard 53 for lead reduction is the fast, low-cost fix for most households, and is often the first recommended step while you sort out anything more serious.
2. Plumbing remediation — if the source is a lead service line or lead solder in your home's own pipes, a licensed plumber can replace the affected fixtures or piping. This is a bigger job and cost than a filter, but it addresses the source rather than filtering around it.

Which approach your state expects — and whether a filter alone satisfies a licensing requirement or whether remediation is expected for a confirmed lead source — is another detail to confirm with your licensing agency rather than guess at.

Not the same hazard as lead paint

It's worth saying plainly: this article is about water, not paint. Lead paint is a completely separate issue — old paint dust and chips, mostly a concern in homes built before 1978 — with its own testing method and its own separate set of state rules. Passing a water test tells you nothing about your paint, and vice versa. If you haven't already worked through the paint side, see our lead paint testing article for that specific pathway. And if radon is also on your checklist, that's a third, unrelated hazard — a gas from the ground rather than anything to do with paint or plumbing — covered in our radon testing article.

Where DaycareFlow fits

DaycareFlow doesn't test your water or track filter replacement schedules — that's a job for a lab, a filter, or a plumber, not recordkeeping software. What it does help with is keeping your test result and any follow-up action in one dated place you can actually find when a licensor asks, instead of an old email or a photo buried in your camera roll.

That's consistent with what the product actually does today: per-child profiles, a live children roster, a calendar-based planned attendance record you confirm with "Mark as happened," and one place to keep the facility-level notes that don't belong to any single child.

Frequently asked questions

Does my state require home daycares to test drinking water for lead?

It depends on your state. Some states, particularly those with older housing stock or plumbing, have built water lead testing into licensed child care facility rules — a one-time test or periodic retesting, sometimes with extra attention for homes on well water. Other states leave it as a recommendation rather than a requirement. Confirm with your state's child care licensing agency.

Where does lead in drinking water actually come from?

It leaches from old lead pipes, lead solder used to join copper pipes (common in plumbing installed before 1986), or brass fixtures and faucets that contain trace lead — not from paint. A home can have zero lead paint and still have elevated lead in its tap water, which is why this is tracked as a separate hazard from lead paint.

How do I test my home daycare's water for lead?

You can use a consumer water testing kit that you mail to a lab, though some states require a state-certified lab test rather than a self-administered kit — check your state's specific requirement first. Sampling is often done as a "first draw" after water has sat in the pipes for several hours, since that's typically when lead concentration peaks.

What do I do if my water tests high for lead?

A faucet-mounted or pitcher filter certified to NSF/ANSI Standard 53 for lead reduction is a fast, affordable fix for most households. If the source is your home's own lead pipes or solder, a licensed plumber can replace the affected plumbing — a bigger step, but one that addresses the source rather than filtering around it.

Is lead in drinking water the same issue as lead paint?

No — they're separate hazards with separate causes and separate state rules. Lead paint is dust and chips from old paint, mainly a concern in homes built before 1978. Lead in water comes from pipes, solder, and fixtures. Testing or passing on one tells you nothing about the other; see our lead paint testing article for that separate pathway.
