Rental properties on private wells raise a mix of testing questions and legal questions, and the two don’t always get untangled clearly between landlords and tenants.

Why Private-Well Rentals Are Different

A rental on municipal water has utility oversight behind it. A rental on a private well doesn’t. That means responsibility for knowing what’s in the water, and for deciding what to do about it, sits with whoever controls the property rather than a utility.

Two Separate Questions, Not One

Whether a well should be tested for radon is a water-quality question. Whether a landlord is legally obligated to test, disclose, or treat is a completely separate legal question, one that depends on the specific lease, property type, and applicable regulations. This article addresses only the first.

Records Worth Keeping Regardless of the Legal Answer

• Water test results, dated and filed somewhere both parties can find them
• Maintenance records for any existing treatment equipment
• Written correspondence about water quality concerns raised by either side

None of this settles a legal question. All of it helps if one ever comes up.

Where NJDEP Fits Into the Picture

NJDEP oversees private well testing requirements in New Jersey, and their published guidance on the Private Well Testing Act is a reasonable starting point for the general regulatory landscape. It won’t answer every situation-specific question, and it isn’t meant to.

When This Needs an Actual Lawyer

Questions about a specific landlord’s obligations, particular lease language, or liability for water quality issues in a rental are legal questions. A real estate attorney familiar with New Jersey rental law is the right resource for those, not a water treatment company and not this article.

Testing Doesn’t Wait on the Legal Answer

Regardless of what the legal side turns out to require, testing a rental property’s well for radon and other contaminants is a straightforward way to know what’s actually in the water. That’s useful information for landlords and tenants alike, independent of any obligation either way.

Get the Water Tested While You Sort Out the Rest

Radon in well water at NJ rental properties raises real questions, some about the water and some about the law. Jersey Radon and Water Treatment can help with testing and treatment but does not provide legal interpretation. For obligations under a specific lease, consult NJDEP or a qualified attorney.
