Licensing Applications and Registration
Well Management Program

In Minnesota, a person or contractor who provides services for the construction, repair, and sealing of wells and some borings (elevator borings, exploratory borings, and bored geothermal heat exchangers) must be licensed by the Minnesota Department of Health (MDH). MDH issues eight different types of licenses, ranging from the well contractor license to more limited or specialty licenses, such as well sealing. MDH licenses the company, and the individual who meets the qualification and exam requirements is considered the certified representative.

The first step in becoming a certified representative is for the individual to submit a Qualification Application, accompanied by the $75 fee, to MDH. In the Qualification Application, the applicant documents work experience and provides letters of reference to verify that work experience. Each license type has specific minimum experience requirements, including a mix of number of hours worked and jobs performed per year for a certain number of years. Once the Qualification Application is submitted to and approved by MDH, the applicant is then authorized to take a written examination. Well contractor applicants must also appear before the Advisory Council on Wells and Borings for an oral examination.

Once the applicant passes the exam(s), the applicant will be sent an original contractor license application, in which the applicant provides company name and related business information, registers drilling machines and hoists, and submits a corporate surety bond and certified representative application. The license fee varies from $75 to $250, depending on the license type. Once the original company license application and the certified representative application are approved, the company is ready for well contracting work in Minnesota.
