Red Flint Sand and Gravel is produced in Eau Claire, Wisconsin, the land of clear water, where there is an abundant source of glacial deposit materials. French voyagers named the city for its clear rivers and marveled at the region’s natural resources. Today the water is still clear, the area is still beautiful, and the natural mineral resources are used worldwide in municipal, residential, and industrial water treatment facilities.
