More than 1 billion people lack access to clean drinking water and 3.4 million die each year from diseases linked to water contamination, according to the World Health Organization. In a report timed for U.N. World Water Day today (mark your calendar for next year), the WHO said it had registered no improvement in the numbers since 1990.
