New Water Source for Hopi Indian Reservation
This article discusses plans for a new community water supply for New Oraibi, a community on the Hopi Indian Reservation in Arizona. The plans called for construction of a well to a maximum depth of 1,200 feet, penetrating the Cowsprings sandstone formation. The mineral content was acceptable except for fluoride, which exceeded the maximum ppm allowed. Drilling continued, which ultimately penetrated two additional sandstone formations, the Entrada and the Navajo. A mixture of all three sources showed fluoride to be within acceptable ppms. The article discusses the design of the well, which allows for flexibility in adjusting the fluoride concentration.
