KPBS has posted a nice audio slide show of the UVeta project in Baja Sur. Water in Baja Sur’s remote areas is frequently from open wells, where the chance of contamination is high. Florence Cassassuce with Engineers without Borders came up with a way to use existing technology to make the water much safer – Ultraviolet light and a bucket.

UV destroys DNA of microbes so they can’t reproduce. This concept has been used for municipal treatment for a while, and over the last few years in higher cost travel items like the SteriPEN. But unlike most portable UV systems the UVeta can clean a lot of water at at a time and is very cheap – They worked with Tijuana producers to reduce the cost of the UVeta to $30.
