22 OCTOBER 2007 -- MONUMENT VALLEY, UT: MARIE CLY, a Navajo Indian living on the Navajo Reservation in northern Arizona, pulls the hose out of barrels after filling 50 gallon barrels with potable water at the well at Goulding's Trading Post near Monument Valley, UT. The well at Goulding's was first dug by Seventh Day Adventists missionaries and is the only source of clean, free water for miles around. More than 30 percent of the homes on the Navajo Nation, about the size of West Virginia and the largest Indian reservation in the US, don't have indoor plumbing or a regular supply of domestic water. Many of these homes have to either buy water from commercial vendors or haul water from public wells. A Federal study showed that the total cost of hauling water was about $113 per 1,000 gallons. A Phoenix household, in comparison, pays just $5 a month for up to 7,400 gallons of water. The lack of water on the reservation means the Navajo are among the most miserly users of water in the United States. Families that have to buy or haul water use only about 15 gallons of water per day per person. In Phoenix, by comparison, the average water use is about 170 gallons per day.  Photo by Jack Kurtz
