A lot of the houses around Keuka Lake are old: village homes in Penn Yan and Hammondsport, farmhouses on the bluff, and cottages that were winterized one room at a time. Old plumbing is part of that charm and part of the risk. Lead can get into drinking water from a lead service line, from lead solder on copper pipe, and from older brass faucets and valves. It doesn’t change how water looks, smells, or tastes, so the only way to know is to look at the pipes and test the water.

This guide covers where lead hides in older lake-area plumbing, what the local public water systems have reported about lead service lines, how to check your own pipes, how to test correctly on village water or a private well, and what to do if a result comes back high. It belongs with our Older Homes guides. Pair it with older homes around Keuka Lake, well water, and drinking water: lake intakes and wells.

Where lead comes from in an older house

The NYS Department of Health explains that lead gets into drinking water when pipes or solder that contain lead corrode, especially where the water is acidic or low in minerals. It can also leach from corroding brass or chrome-plated brass faucets and fixtures, particularly with hot water (NYS DOH: Lead in drinking water). The main sources are:

Lead service lines. The pipe that runs from the water main to the house. EPA says that where homes have lead service lines, those pipes are typically the most significant source of lead in the water (EPA: Basic information about lead in drinking water).
Lead solder joining copper pipes, common in older work.
Brass and chrome-plated brass faucets, valves, and fittings. EPA says that among homes without lead service lines, these and lead solder are the most common problem.
Galvanized steel pipe that sat downstream of a lead pipe can collect lead in its corrosion and release it later. That’s why water systems count those lines too.

The 1986 line, and why “lead-free” isn’t zero

DOH says homes built before 1986 are more likely to have lead pipes, fixtures, and solder. Homes built after 1986 have “lead-free” plumbing but can still contain trace amounts. Under the Safe Drinking Water Act, “lead-free” now means a weighted average of no more than 0.25% lead across wetted surfaces of pipes, fittings, and fixtures, and 0.2% for solder and flux (EPA). A 1920s house that was re-plumbed in 1990 may be fine; a 1995 cottage with a 1970s faucet may not be. The age of the parts matters more than the age of the house.

What Keuka-area water systems have reported

Federal rules required public water systems to build an inventory of service line materials, and NYS DOH posts each system’s summary in its lead service line inventory list. Here’s what the systems around the lake reported, as posted when we checked on October 14, 2026:

Water system	Total service lines	Lead	Galvanized needing replacement	Unknown
Village of Penn Yan	2,444	213	63	113
Village of Hammondsport	368	0	0	0
Keuka Park Consolidated Water District	1,210	0	0	0
Milo Water District	556	0	0	0
Pulteney Water District	432	0	0	0

A few notes on reading this:

Penn Yan certified its inventory on October 5, 2025. Most of its 213 lead lines are on the system side (206), with 10 on the customer side and 82 customer-side galvanized lines. In 2025 the village hired a contractor to excavate and identify unknown lines, work that local news said would run May through October and wouldn’t include piping beyond a homeowner’s water meter (Finger Lakes Daily News). The inventory is available at the Department of Public Works, 111 Elm St., Penn Yan.
A zero in the table is about the service line only. It doesn’t tell you anything about the solder, faucets, or galvanized pipe inside a particular house.
Testing results are separate from the inventory. Hammondsport’s 2024 water quality report, for example, says the 90th-percentile lead level from its 10 sampled homes was 0.012 mg/L and the action level wasn’t exceeded (Village of Hammondsport 2024 water quality report, PDF). Your water system’s annual report is the place to look for those numbers.

If you’re buying in a village, ask the water department what the inventory says about that address, on both the public side and the customer side.

The rules are tightening

Today’s federal Lead and Copper Rule requires action when more than 10% of sampled taps exceed 0.015 mg/L (15 parts per billion), as DOH explains. EPA’s Lead and Copper Rule Improvements, published in October 2024, lower that action level to 0.010 mg/L and generally require systems to replace lead and galvanized-requiring-replacement service lines under their control within 10 years, with most requirements taking effect November 1, 2027 (Federal Register: LCRI final rule). Federal rules can be revised, so check with your water system for its current schedule. New York also offers grant funding to some municipalities through its Lead Service Line Replacement Program (DOH).

How to check your own pipes

You can do a first check yourself in a few minutes. EPA’s Protect Your Tap guide walks through it with nothing more than a coin or key and a magnet:

Find where the water line enters the house, usually in the basement or crawl space near the meter or main shutoff.
Scratch the pipe gently with the edge of a coin or key. Lead is soft and scratches to a shiny silver. Copper looks like a penny.
Try a magnet. A magnet sticks to galvanized steel but not to lead or copper.
Look at the joints on copper pipe. Dull gray solder on older work may contain lead; you can’t tell by looking, which is why testing matters.
Note old faucets and valves, especially at the kitchen sink.

Don’t scrape through a pipe or disturb it hard. If you think you’ve found lead, leave it alone and call the water system and a licensed plumber.

How to test your water

Use a certified lab

DOH says certified commercial laboratories test for lead in drinking water and that the cost ranges from $15 to $50 per sample. New York’s Wadsworth Center keeps the list of ELAP-certified labs. For a private well, DOH recommends against relying on store-bought kits or tests by water treatment vendors, because they don’t meet ELAP standards (DOH Fact Sheet #7, PDF).

If you’re on village or district water, call the water system first. Many will tell you what the records show for your address and how they handle customer testing.

How samples are usually taken

Your lab will give you bottles and instructions, and you should follow them exactly. Lead testing often uses two samples:

A first-draw sample, taken from a cold tap after the water has sat in the pipes for at least six hours, without flushing. This shows what’s in water that has been sitting against your plumbing.
A flushed sample, taken after running the cold water for a couple of minutes. This helps show whether lead is coming from the service line and fixtures or from deeper in the system.

Sample at the tap you actually drink from, usually the kitchen, and before any filter. Testing filtered water tells you about the filter, not the pipes.

Private wells: lead is on the schedule too

Lead isn’t only a village-water issue. DOH says that even with a private well, lead can be a concern if the home’s plumbing contains lead solder or lead materials. DOH’s well guidance recommends testing for bacteria every year and for lead and other contaminants every 3 to 5 years, and after repairs or changes to the system (NYS DOH: Test your well). Because DOH says corrosion is more likely when water is acidic or low in minerals, look at the pH, hardness, and alkalinity results from your well test too; they help explain a lead result in a house with old copper and solder. Our well water guide covers the full test list.

Seasonal cottages

Water that sits for weeks in a closed cottage has had a long time against the plumbing. When you open up in spring or arrive for a long weekend, flush every tap before drinking, and if you test, ask the lab whether to sample after a normal overnight stand rather than after the house has been empty for a month.

Reducing lead while you sort it out

DOH lists steps that help right away:

Run the water for at least 30 seconds, or until it turns cold, if it hasn’t been used for several hours.
Use only cold water for drinking, cooking, and baby formula. Lead dissolves more easily into hot water. Never use hot tap water for formula.
Don’t boil water to remove lead. Boiling doesn’t reduce it.
Use a certified filter or certified bottled water if your home has a lead service line or lead-containing plumbing. DOH points to NSF’s listings of filters certified for lead reduction, and EPA says a filter only helps if it’s certified to remove lead and the cartridge is replaced on time.
Replace leaded fixtures with products certified for lead content.

Fixing the problem

Public-side lead line: talk to the village or district. Under the new federal rule, systems are building replacement programs, and some state funding goes to municipal replacement projects.
Customer-side lead or galvanized line: this is generally the owner’s pipe. Ask the water system whether it coordinates replacement of both sides together, and follow its flushing instructions afterward.
Lead solder or old fixtures inside: a licensed plumber can replace sections, valves, and faucets. Use certified lead-free parts.
After any plumbing work, flush the lines well and test again.

Lead is also in old paint and dust, not just water, and DOH’s lead program covers lead-safe renovation. If you’re opening walls in an older home, that guidance applies too.

What to have on hand

These are the simple things that help while you test or wait on a fix. Check the certification on the actual product before you buy.

For the test itself, use an ELAP-certified lab, not a store kit.

A buyer’s checklist for older Keuka Lake homes

Ask when the house was built and when it was last re-plumbed.
On village or district water, ask the water system what its service line inventory shows for the address, on both sides of the curb stop.
Look at the pipe where water enters the house, using the coin-and-magnet check.
Ask the seller for any past lead test results; for a well, ask for the full well test history.
Make a certified lab lead test part of your water testing before closing. Our buying guide explains how to fit tests into the contract timeline.
Budget for replacing a customer-side lead or galvanized line, old faucets, or soldered sections if they turn up.
While you’re in the basement, check the radon and oil tank questions too: see our radon guide and heating oil tanks guide.

Frequently asked questions

Do Keuka Lake village water systems have lead service lines?

According to the inventories posted by NYS DOH, the Village of Penn Yan reported 213 lead service lines, 63 galvanized lines needing replacement, and 113 unknown out of 2,444. Hammondsport, Keuka Park, the Milo Water District, and the Pulteney Water District reported none. Ask your water system about your specific address.

My house was built after 1986. Can it still have lead in the water?

It is less likely, but possible. DOH says post-1986 “lead-free” plumbing can still contain trace amounts of lead, and older faucets or fixtures may have been reused. Testing is the only way to know.

How much does a lead water test cost?

NYS DOH says certified commercial labs charge about $15 to $50 per sample. Use an ELAP-certified lab and follow its sampling instructions.

Does a private well need a lead test?

Yes, periodically. DOH recommends testing private wells for lead and several other contaminants every 3 to 5 years, plus bacteria every year, because lead can come from the home’s plumbing even when the well water itself is fine.

Will boiling water remove lead?

No. DOH says boiling does not reduce lead. Use cold water, flush the tap, and use a filter certified for lead reduction or certified bottled water if your plumbing contains lead.

How can I tell if my service pipe is lead?

Where the pipe enters the house, gently scratch it with a coin or key. Lead is soft and turns shiny silver, and a magnet will not stick to it. Copper looks like a penny, and a magnet sticks to galvanized steel. EPA’s Protect Your Tap guide walks through it.
