New Jersey lead-in-water testing for schools & childcare
New Jersey requires public school districts to test all drinking-water outlets for lead (school facilities regulations) and requires licensed child care centers served by a community water system to test for lead and copper (N.J.A.C. 3A:52-5.3). The lead action level is 15 ppb; outlets exceeding it must be taken out of use and parents/staff notified.
- Applies to
- both
- Action level
- 15 ppb
- Frequency
- Schools: every 3 years (cycle years included 2021-2022 and 2024-2025). Child care: required for covered centers (verify interval with NJ DCF).

Schools: triennial lead testing of all drinking-water outlets required (N.J.A.C. 6A:26; NJDOE Lead in School Drinking Water program). Child care: NJDCF requires lead/copper water testing every 3 years at license renewal (effective 3/6/2017). Action level 15 ppb. Sources: nj.gov/education/lead/, nj.gov/dep/watersupply/pw_child.html
Find a certified lab in New Jersey
PATHWAY TO FIND A CERTIFIED LAB FOR LEAD-IN-DRINKING-WATER TESTING How drinking water lab certification works (VERIFIED, EPA): - Under the Safe Drinking Water Act, STATES hold primacy and run the certification of laboratories that analyze drinking water. Public water systems must use a state-certified lab, and EPA approves the analytical methods while states manage the certification process itself. EPA does NOT test residential/commercial water on request, and does not run a single national "find a lab" search for drinking water; it routes you to your state program. (Source: epa.gov/dwlabcert; epa.gov/lead/can-i-get-my-water-tested-lead) - EPA's own lead-in-water guidance states: testing is the only reliable way to detect lead (you cannot see/taste/smell it), and "A list of certified laboratories are available from your state or local drinking water authority or on EPA's website." STEP-BY-STEP PATHWAY: 1. Start at EPA's directory of state certification programs (the primary, authoritative entry point): https://www.epa.gov/dwlabcert/contact-information-certification-programs-and-certified-laboratories-drinking-water . This page links to a PDF and to each state's drinking-water lab certification program and contacts. 2. Use the EPA PDF "State Certification Programs Certify Laboratories to Conduct Drinking Water Analyses": https://www.epa.gov/system/files/documents/2023-03/state-cert-programs-certify-labs-to-conduct-drinking-water-analyses.pdf 3. Contact your STATE drinking-water program (or local water authority) to obtain its current list of state-certified labs and ensure the lab is certified for LEAD in drinking water specifically. NATIONAL LOCATORS (cross-state lab search tools), use to confirm/locate accredited labs, then verify state certification: - TNI/NELAP "LAMS" (National Environmental Laboratory Accreditation Management System): searchable by lab name, TNI lab code, location, state, and accreditation body; covers environmental matrices including DRINKING WATER. Search: https://lams.nelac-institute.org/search . NELAP accreditation is delivered through state/AB accreditation bodies (e.g., FL, IL, KS, LA, MN, NH, NJ, NY, OK, OR, PA, TX, UT, VA). NELAP Accreditation Bodies list: https://nelac-institute.org/content/NELAP/accred-bodies.php - A2LA (American Association for Laboratory Accreditation): Directory of Accredited Organizations, searchable by organization/scope, including environmental/water testing scopes. Directory: https://customer.a2la.org/index.cfm?event=directory.index CRITICAL ACCURACY CAVEAT, do NOT use NLLAP for water: EPA's National Lead Laboratory Accreditation Program (NLLAP) accredits labs ONLY for lead in PAINT CHIPS, DUST WIPES, and SOIL, NOT drinking water. Do not present NLLAP (epa.gov/lead/national-lead-laboratory-accreditation-program-list) as a locator for lead-in-WATER labs. NLLAP recognizes accrediting bodies AIHA-LAP, A2LA, Perry Johnson Laboratory Accreditation, ANAB/ACLASS, and International Accreditation Service. Note A2LA appears in both contexts (paint/dust/soil via NLLAP AND, separately, environmental water testing via its general accreditation), so always check the lab's specific scope/matrix. BOTTOM-LINE GUIDANCE FOR SCHOOLS/CHILDCARE: Use a lab that is certified BY YOUR STATE for lead in drinking water. Begin at the EPA state-certification directory, then verify via TNI LAMS or A2LA. Confirm the lab's scope explicitly covers lead in drinking water (not paint/dust/soil).

New Jersey requires lead-in-water testing in public schools (administered through the Department of Education and NJDEP) and addresses lead in licensed child-care facilities. Labs must be certified by the NJDEP Office of Quality Assurance for lead in drinking water. Certification status changes over time, so verify a lab's current certification for the specific analyte (lead) and matrix (drinking water) before sampling. Follow first-draw sampling guidance, retain your chain-of-custody and results, and confirm turnaround if you're working to a remediation or reporting deadline. We list only labs we could re-confirm; some NJDEP-certified labs may not appear here until re-verified.
