Well Driller List

State rules

Maryland

Maryland licenses well drillers through the State Board of Well Drillers at the Maryland Department of the Environment. The board's page says it was established under Title 13 of the Environment Article, sections 13-101 through 13-602. The board meets at the department, generally on the third or fourth Wednesday of the month, and the public may attend. Licensing examinations are offered in English and in Spanish. The page says a request for the Spanish version must reach the board at least two weeks before the exam. The contact line printed on the page is 410-537-4466. The page links a roster of active licensees. This record does not copy names from that roster.

COMAR 26.05.01.03 says an applicant is licensed when the person files the board's application, qualifies for the examination, receives a passing score or a waiver, provides evidence that bonding and liability insurance requirements will be met when those requirements apply, and pays the license fee. The regulation also describes how a journeyman or master who passes the exam for the other category, water supply or geotechnical, is licensed in that additional category. COMAR 26.05.01.05 says an apprentice applicant must have a sponsor who is licensed by the board and actively engaged in well drilling.

The apprentice rule says the maximum term of an apprenticeship is 60 months or 10,000 hours of on-the-job training, with a possible extension. An apprentice or well rig operator practices under the responsibility of a principal licensee and must be able to reach that licensee by on-site telephone or radio. The board's page links study topics for apprentice, journeyman, and master examinations, continuing education guidance, the exam schedule, well construction regulations in COMAR 26.04.04, and the board regulations in COMAR 26.05. Those construction rules are separate from the license itself.

A property owner should ask for the license class and category, not only the company name, and should verify the license on the board's current roster rather than an old PDF. The board's own roster note, as described on the program materials, tells consumers to confirm that a license is active before hiring. Bond and insurance evidence is part of licensure when the regulation says it applies. No fee amount is copied into the fee field of this record. The board page and the two COMAR chapters are the official path for license questions and construction questions.
