To the editor: In discussing the plan to use Flagstaff's A+ reclaimed water to make artificial snow, Randy Pellatz (Utility Director for the city of Flagstaff) writes on July 22 that Flagstaff's A+ reclaimed water meets all drinking water quality standards. In other words, it is legally potable in the eyes of the state of Arizona. Flagstaff city government is rightfully concerned about maintaining an adequate supply of potable water in view of expected increase in demand as the town grows. Why else buy up land and its groundwater rights tens of miles east of town? Getting any of that water to town will be a very expensive drilling and pumping proposition. So it seems quite cost ineffective to make snow from the existing A+ reclaimed liquid, unless making snow is more important than slaking the thirst of people. It's true that some snow melt from the artificial stuff would eventually percolate downward and add to the regional groundwater resource that the city's wells now tap. However, as much as 50 percent of the snow will simply disappear into the atmosphere through sublimation and head downwind. Why send that valuable drinkable stuff to Kansas when it's badly needed here?
