In rural Bangladesh, ponds and rivers are used by animals and humans alike for bathing, drinking and washing causing them to be highly contaminated by bacteria, human and animal waste. Without a properly planned sanitation system, the distance of tube wells from latrines or sewage-contaminated ponds may be insufficient to avoid contaminating the well water. In most cases, pure water can be reached by digging a small diameter well - 75 to 150 feet deep, depending on the level of ground water. Field social workers are trained to make sure that new wells are located a minimum of 75 feet from a known contaminated source. Any wells found to be closer than 75 feet are removed.
In some areas, levels of arsenic in the water cause great hardship, long-term illness and suffering for those who have no choice but to drink it. In these areas special arsenic wells are dug to depths of 700-800 feet to bypass the arsenic.
