Extensive areas of irrigated land in Colorado have become salinized and their associated water supplies have become similarly degraded. The Arkansas River is well known for the degree of its progressive downstream salinization only in relatively recent few years has it been recognized that the Lower South Platte River and associated irrigated lands are becoming increasingly salt affected. Substantial programs have not been implemented to rejuvenate...

Pavement construction and maintenance problems due to the presence of sulfates in limestabilized subgrade soils have been widely reported in many transportation projects. In Colorado, problems associated with sulfate-induced distresses have been observed at the Denver International Airport and, more recently, at the U. S. Highway 287 Berthoud By-pass project. It would be desirable if CDOT engineers could count on alternative soil stabilization techniques...
