This project, demonstrating the application of reverse osmosis and electrodialysis to drinking water supplies, continued during 1979 with the mobile unit located first at San Jon from January through April, and the remainder of the year in Alamogordo. It was the second visit to San Jon, principally to give an extended operation on a high fluoride supply. Operation at Alamogordo was directed to assist the proposed large-scale desalination project in the Tularosa Basin.

The units operated satisfactorily in both locations, i.e., product water was certified by the EID as meeting state drinking water standards. Product water was delivered to the San Jon community system. In Alamogordo, product water was recombined with reject brine to provide sufficient feed for a small evaporation pond. Data were taken on pond evaporation to substantiate available values.
