William F. Guyton, 95, a pioneer in groundwater hydrology study and founder of one of the first consultants in the field, died on March 2 in Austin, Texas.
He was among the first employees in the U.S. Geological Survey's groundwater branch, beginning his career there in 1939.
Guyton founded, in 1951, Austin-based William F. Guyton Associates, known for expertise in deep-well technology, large-scale water-supply development and hydrogeo-chemistry.
The firm was acquired by consultant Leggette, Brashears & Graham in 1992 and now operates as LBG-Guyton Associates.
Guyton was a past president of the Austin chapter of the American Society of Civil Engineers and a lifetime member of the National Groundwater Association.
