David L. Holm

A pioneer in the treatment of drainage of toxic matter from inactive mines. In 1984 he designed a system to neutralise mine acidity which uses low-cost materials and does not require continued electrical and chemical inputs.

The system has been successfully used at three abandoned mines by the Colorado Department of Natural Resources. It is an environmentally-sound approach to pollution control in mining.
