Cambodia has plenty of available groundwater; the problem is that not much of it is safe enough to drink. Most ponds or open wells are contaminated with industrial runoff, human waste or contaminants like arsenic and E. coli bacteria. In 2010, Cambodia had some of the highest infant and under-five mortality rates in the region, at 43 and 51 per 1,000 live births.

Here, we invest in the BioSand Filter (BSF), which uses stone, sand and a biological layer to remove 99% of harmful bacteria in water poured through it. Families build their own BSF and keep it at their home for daily use.
