Private Well Testing for Rental Properties
Landlords of private-well rental properties generally face a recurring PWTA testing obligation, not a one-time event.
Short answer: Landlord testing under the PWTA generally recurs on a cycle rather than happening only at lease signing. Verify the current required interval and any exceptions with NJDEP before assuming a past test remains valid.
Who this is for: landlords and tenants of New Jersey rental properties served by a private well.
What landlords should track
- The date of the most recent PWTA test and when the next one is due under the current required interval
- Which certified lab or collector performed the testing
- Where results were reported and to whom
- Any tenant notification requirements tied to results
What tenants should know
Tenants can ask their landlord for the current PWTA test results and the date of the most recent sampling. This site does not advise tenants on lease disputes, habitability claims, or legal remedies — consult a tenant's rights resource or attorney for those questions.
Common mistakes
- Assuming a single PWTA test at move-in satisfies an ongoing landlord obligation
- Not keeping records of testing dates and results across tenancies
- Confusing PWTA landlord testing with optional routine testing

How often must a landlord retest a rental property's well?
PWTA landlord testing generally recurs on a cycle under the Act. Confirm the current required interval and any exceptions with NJDEP rather than relying on a fixed number, since program details can change.
