New Jersey Well Regulations and Permitting

What the exam tests

New Jersey well regulations test the permitting chain and the driller's legal responsibilities. You need to know who issues approvals, what must be filed, and where local rules add requirements.

Core rules

  • The NJDEP regulates well construction, maintenance, and sealing under N.J.A.C. 7:9D. A licensed well driller must construct, repair, or abandon a well; pump installation is separately licensed.
  • A well construction permit is required before drilling, and the permit must be available at the site. Monitoring wells, public-supply wells, and irrigation wells can have additional review.
  • Submit the well record (driller's log, casing, screen, grout, yield test) to NJDEP within the required time after completion, and give the owner a copy.
  • The PWTA requires testing before sale or lease; the lab reports to the buyer or lessee and the local health department, and failing results trigger notice and remediation requirements.
  • Setback and water-use rules matter: wells must be located away from septic systems, fuel tanks, and sources of contamination; larger diversions may need a water-use permit or registration.
  • Local health departments may impose additional permitting and testing conditions.

Worked example

A homeowner wants a new well in a coastal township. Before mobilizing, verify the NJDEP well permit, confirm the proposed location meets setback distances from the septic field, and check whether the site is in a flood hazard or wetlands area that triggers another approval. After completion, submit the well record and provide the owner with the yield and water-quality results. Drilling first and doing paperwork later is a violation even if the well is perfect.

Traps

Assuming the county or township issues the state well permit. Using a pump installer's license to cover drilling. Filing a well record with estimated depths rather than measured casing and screen intervals. Ignoring PWTA because the buyer waived inspection - the statute, not the contract, controls.
