All over East Africa-indeed, all over Africa-it is normal for people to walk a kilometer or two or six for water. In more arid areas, people walk even greater distances, and sometimes all they find at the end is a pond slimy with overuse. More than 90 percent of Africans still dig for their water, and waterborne diseases such as typhoid, dysentery, bilharzia, and cholera are common. The bodies of many Africans are a stew of parasites. In some areas the wells are so far below the earth's surface that chains of people are required to pass up the water.
