In Iowa, all well drilling services and pump installation/repair services must be performed by a IDNR certified well contractor. The IDNR certified well contractor must be on the job site at the time well services are being performed.

IDNR certified well contractors are individuals who have proven field experience in the area of the certification earned and have successfully passed an examination demonstrating their qualifications to perform well drilling or pump installation/repair services. In addition to passing an examination, certified well contractors need to earn continuing education units (CEUs), and follow all well regulations and contractor obligations as outlined in Iowa Administrative Code 567 Chapters 38, 39, 49 and 82. Well contractor certification is renewable for two year periods if all eligibility requirements,*.pdf are met.

The goal of the well contractor certification program is to ensure that the professionals working on water supply wells have the minimum levels of knowledge and experience required by rule and that they understand how the rules protect the groundwater.
