The Association was first formed in 1954 with a small group of Drillers from Central Maryland area.  In 1956 the Association was incorporated to include all Well Drillers in the State of Maryland.  The prime purpose of the association was, and continues to be, to upgrade the industry and to secure protection for the customer.

Only after many meetings and many years of hard work, was the Maryland State Board if Well Drillers created on September 1 1968 when signed into law by Spiro Agnew the Governor of Maryland.
The duties of the Board of Well Drillers are to administer and provide for the enforcement of the Well Drilling laws, as applicable to the business of Well Drilling.
