Lead in drinking water at rental homes

Lead in tap water can be a real issue at rental homes, especially in older housing, but tenants and landlords usually can take clear steps right away. The safest approach is to check the water source, review the utility’s records, use cold water for drinking and cooking, and get the home’s tap water tested if there is any doubt. (epa.gov)

Why lead can show up in a rental home’s water

Lead usually gets into drinking water after the water leaves the treatment plant. EPA says lead can enter water when plumbing materials corrode, and the most common sources are lead pipes, faucets, fixtures, and service lines that connect a home to the water main. In homes with lead service lines, that line is often the biggest source. Homes built before 1986 are more likely to have lead pipes or plumbing materials that contain lead. (epa.gov)

Lead is especially concerning because EPA’s health goal for lead in drinking water is zero, and children, infants, and fetuses are more vulnerable to harm. EPA also notes that even if the utility’s water meets system-wide rules, a home’s own plumbing can still add lead at the tap. (epa.gov)

For renters, that means two things can be true at once: the water system may be following the rules, and a specific apartment or house may still need testing. It also helps to remember that water is only one possible lead source in an older rental. Paint, dust, and soil can matter too. (epa.gov)

What renters should do first

If you are worried about lead in drinking water, start with a simple checklist.

1. Ask how the home gets water. Find out whether the rental is served by a community water system or by a private well. If it is on public water, ask whether the utility or landlord knows the service line material. If it is on a private well, ask for recent well test results because private wells are not regulated by EPA the way public systems are. (epa.gov)
2. Ask for the latest water records. EPA requires community water systems to prepare an annual water quality report, called a Consumer Confidence Report, by July 1 each year. Water systems also must maintain service line inventories, and EPA says those inventories must be publicly accessible. (epa.gov)
3. Use only cold water for drinking, cooking, and mixing baby formula. EPA says hot water can dissolve lead more quickly, so cold water is the safer choice for anything you eat or drink. (epa.gov)
4. Do not rely on boiling. EPA is clear that boiling water does not remove lead. (epa.gov)
5. Consider a filter that is certified to remove lead. EPA recommends using a drinking water filter certified to reduce lead and following the cartridge replacement directions carefully. (epa.gov)
6. Get the tap water tested if you are unsure. EPA says testing is the only sure way to know whether harmful amounts of lead are in your drinking water. EPA’s Protect Your Tap guide says certified lab testing often costs about $15 to $100, and some states or utilities may help pay for testing or lead service line replacement. (epa.gov)

If you want to check local rental lead rules alongside drinking-water concerns, use the Rental lead-safe check, browse the site’s state-by-state pages, or search your city, county or ZIP. Local lead programs and rental rules can differ a lot from one place to another. (epa.gov)

How to check the official record for your address

Start with the water utility. EPA says you can ask the utility whether the pipe connecting the home to the water main is made from lead. Under EPA’s lead service line inventory rules, water systems must keep information on service line materials, and where ownership is split, inventories track both the system side and the customer side. (epa.gov)

EPA also says water systems must notify people if they are served by a lead service line, a galvanized line that may be contaminated by lead, or a service line of unknown material. That notice matters for rentals because the landlord may not be the only party involved; sometimes the utility controls one part of the line and the property owner controls another part. (epa.gov)

A utility report is useful, but it is not the whole story. EPA says a home can still have lead from interior plumbing materials and that testing the home’s own tap water is the only sure way to confirm whether lead is present. So if the address is old, the line material is unknown, or a child drinks formula mixed with tap water, it makes sense to push for testing rather than stopping at the annual report. (epa.gov)

What landlords and property managers should do

Landlords do not need to guess. A practical first step is to gather the utility’s current Consumer Confidence Report, check whether the address appears in the utility’s service line inventory, and ask the utility what is known about the service line on both the public side and the property side. EPA’s service line guidance recognizes that ownership can be split, so the answer is not always as simple as saying the utility or the owner is fully responsible. (epa.gov)

A good landlord checklist looks like this:

• Keep the basics in one file: the latest utility report, any service line notices, past water test results, and plumbing repair records. (epa.gov)
• Arrange testing when risk is higher: for example, when the service line is known or suspected to be lead, when recent plumbing work may have disturbed old materials, or when a baby, young child, or pregnant person lives in the home. (epa.gov)
• Give clear instructions to tenants: use cold water for drinking and cooking, do not use hot tap water for formula, and do not assume boiling fixes the problem. (epa.gov)
• Use lead-reducing filters properly if they are part of the short-term plan: EPA says certified filters can help, but only if the correct cartridge is installed and replaced on time. (epa.gov)
• Ask about payment help: EPA’s Protect Your Tap guide says some states or utilities offer programs that help pay for water testing or lead service line replacement. Landlords may also want to review local assistance options and Lead hazard control grants for landlords and homeowners. (epa.gov)

Because landlord duties can depend on state law, local housing code, lease terms, and which part of the line is privately controlled, it is smart to confirm the current rule with the water utility, local health department, housing code office, or state drinking water program before treating any deadline or repair step as final. (epa.gov)

If the rental home uses a private well

Private wells are a different situation. EPA says private wells are not regulated by EPA or required to follow EPA’s drinking water standards. That means renters should not expect the same public reporting system that applies to a city or community water utility. (epa.gov)

If a rental home uses a well, ask the owner for recent test results and ask who maintains the well and any treatment equipment. If there are no recent results, ask the owner to work with a certified lab and the local health department or state well program before move-in or as soon as a concern comes up. (epa.gov)

For tenants, a missing paper trail is a warning sign. With a public system, you can usually review a utility report and service line information. With a private well, you often need to ask more questions and request actual test results. (epa.gov)

How drinking-water rules fit with lead-paint rules

Many renters already know about lead forms at lease signing, but those forms are usually about lead-based paint, not tap water. EPA says the federal Lead-Based Paint Disclosure Rule requires known information about lead-based paint and lead-based paint hazards to be disclosed before the sale or lease of most pre-1978 housing. (epa.gov)

That rule is important, but it is not the same as checking drinking water. A family in an older rental may need to think about both issues at once: possible lead in paint, dust, or soil, and possible lead in water from service lines or plumbing. For the paint side, see The federal lead disclosure rule for pre-1978 homes and Lead-safe certificates for rentals: who needs one. (epa.gov)

When to move faster

Do not wait on a routine paper chase if the home has a known lead service line, the service line material is unknown, recent construction may have disturbed old lines, or an infant, young child, or pregnant person will be drinking the water. EPA says nearby construction can suddenly cause more lead to be released from a lead service line, and infants who drink formula mixed with contaminated tap water can face higher exposure. (epa.gov)

In those situations, contact the landlord and water utility right away, ask about immediate precautions, and consider asking a health care provider whether blood lead testing makes sense for a child in the home. EPA notes that young children are especially vulnerable to lead’s effects. (epa.gov)

Frequently asked questions

Is showering or bathing safe if I am worried about lead in water?

Usually yes. EPA says bathing and showering should be safe even if the water contains lead over EPA’s action level because human skin does not absorb lead in water. The bigger concern is water you drink or use for cooking or formula. (epa.gov)

Will boiling water make it safer?

No. EPA says boiling water does not remove lead. It can make people feel like they are fixing the problem when they are not, so use cold water, consider a certified lead-reducing filter, and push for testing instead. (epa.gov)

Does the landlord have to pay for testing or pipe replacement?

It depends. EPA’s service line guidance shows that service line ownership may be split between the water system and the customer side, and repair duties can also be shaped by state or local rules. In some places, utilities or public programs help pay for testing or replacement, but not everywhere. (epa.gov)

If I got a federal lead disclosure form, does that tell me the water is safe?

No. That form is about known lead-based paint and lead-based paint hazards in most pre-1978 housing. It does not replace checking the utility’s records or testing the home’s tap water for lead. (epa.gov)
