In the slums of Kibera in Nairobi, Kenya, about 1 million poor people pay up to 30 times more for water of dubious quality brought to them in old tanker trucks than middle-class citizens pay for clean and safe water provided by the local public water utility via standard household connections.
Some may be shocked by these disturbing disparities in the developing world, but a lack of access to safe, affordable and clean water is also an issue in California, particularly in the Central Valley and along the Central Coast. In these communities, more than 90 percent of drinking water is sucked from contaminated groundwater sources. All told, more than 150,000 California residents lack safe water for drinking, bathing and washing dishes; even more have water service disconnected because they cannot afford to pay their bill.
