“Should I check my water for lead?”
Certified Lead Testing · NY · NJ · CT · Since 1991

Yes. Check Your Water for Lead.

Certified laboratory lead testing for homes, apartments, co-ops, condominiums, commercial properties, schools, and real-estate transactions. Lead has no color, taste, or odor, so laboratory testing is the only reliable way to know what is present in your water.

NYS ELAP Certified Results NELAP Accredited Analysis Full Chain of Custody EPA-Approved Analytical Methods

“My building is old. Do I need to check for lead?”

Yes. Pre-war buildings, brownstones, and homes built before 1986 have the highest risk of lead plumbing. Only certified lab testing tells you what's actually at your tap.

“My water looks clear. Can it still have lead?”

Yes. Lead has no color, taste, or odor at any concentration. Clear water can contain lead at levels far above the EPA action threshold. Only certified laboratory analysis confirms it.

“I'm buying a home. Should I check the water for lead?”

Yes. Pre-purchase certified lead testing is one of the most important steps for any home buyer, especially in homes with older plumbing. Certified results accepted by real estate attorneys.

Checking water for lead — questions

No. The EPA has stated there is no safe level of lead in drinking water. The EPA action level of 15 ppb triggers regulatory response for public systems — but this is not a safe level. Any amount of lead exposure is cause for concern, particularly for children and pregnant individuals.
Home test kits cannot detect lead at concentrations relevant to the EPA action level, cannot identify contamination source, cannot provide certified results accepted by regulatory agencies, and cannot be used for school compliance or real estate transactions. Only NYS ELAP certified analysis provides results you can act on.
Anyone in a home, apartment, co-op, condo, or commercial property with plumbing over 30 years old; home buyers before closing; tenants with concerns; school and daycare administrators; property managers; and anyone whose water has a metallic taste or whose fixtures show staining.
Contact us and we'll schedule on-site sampling at your property. 7 or more business days is typical, with expedited options often available. Call NY (212) 461-3879 · NJ (908) 772-8601 · CT (203) 780-2022 for scheduling and current availability.

    Why test for lead?

    Lead in water is invisible and often undetectable without proper lab testing. Early testing helps identify risks before they impact health, especially in older properties or properties with aging plumbing systems.
