Dedicated to protecting and promoting Ontario's most precious resource ground water. The OGWA was established in 1952.

Approximately 3 million people in Ontario rely on ground water as their primary source of potable water.  Ground water is often the only source of clean water for drinking, farming, and manufacturing. A number of municipalities use ground water as the major source of their citizens water supply. The Ontario Grou nd Water Association was created in 1952 as a not-for-profit organization to facilitate various sectors of the ground water industry coming together for delivery of safe, clean water supplies throughout the province.

Provincially Licenced Water Well Technicians are members of Essential Services.
