Feature

The SODIS solar water purification system (TCS for 20 May 2005 and Wanderings #95) has an added benefit in that it can aide in reducing the amount of arsenic contamination in drinking water. Search on --- <SORAS>

Arsenic contamination is a serious hazard in Cambodia and Bangladesh and many of the other developing countries. Fortunately there are DIY methods for arsenic reduction and water purification available to these populations, as long as minimal funding and the technology/education are made available at the “grass roots” level.
