NJ Child-Care Drinking Water Certification: Step-by-Step
A walkthrough of the certification workflow licensed New Jersey child-care centers must complete, separate from any school lead-testing requirement.
Short answer: Identify your water system type, complete required sampling through a certified lab, obtain the NJDEP Safe Drinking Water Certification letter, and track renewal or recertification triggers such as a change of source or plumbing.
Who this is for: licensed child-care center directors, owners, and facilities staff preparing for or renewing drinking-water certification.
Step-by-step
- Identify your water system. Determine whether your center is served by a public community water system, a noncommunity public system, or a private well — this determines your certification path.
- Confirm current sampling parameters. Check current NJDEP/NJDOH guidance for the specific analytes and procedures required for your facility type.
- Use a certified laboratory. Required sampling must go through a lab certified for the applicable parameters.
- Obtain your certification letter. Once sampling and any required steps are complete, obtain the NJDEP Safe Drinking Water Certification letter for your center.
- Track renewal and recertification triggers. A change of ownership, water source, or plumbing may require recertification even outside the normal renewal cycle.
Public system vs. private well facilities
If your center is on a public water system, part of your certification path involves confirming your system's identity and status rather than independently testing every public-system parameter yourself. If your center is on a private well, you are responsible for the full certified sampling process directly, similar in spirit to a homeowner's private-well obligations but governed by the child-care-specific certification requirements rather than routine homeowner testing.
What happens when results do not meet standards
Follow current NJDEP/NJDOH corrective guidance for your facility type. This may include remediation steps, retesting, or interim measures before certification can be completed or renewed. Contact NJDEP/NJDOH directly for facility-specific direction — this site cannot tell you what corrective path applies to your specific result.
Common mistakes
- Treating this as the same process as a school Statement of Assurance
- Forgetting to recertify after a change of ownership, source, or plumbing

How long does certification last before renewal?
Renewal timing depends on current NJDEP/NJDOH rules and any facility-specific triggers such as a change of source. Confirm your center's specific renewal schedule directly with NJDEP/NJDOH.
