The list of things we take for granted is long and exhaustive. Water, especially potable water, is high on the list. The good news for millions of people who live without safe drinking water is solar water disinfection (SODIS). The simple process has been extensively researched in Sweden.
To disinfect the water, gather water from any source (pond, puddle, etc.) choosing the least murky. Put into a PET plastic bottle. Lay on a metal surface in the sun for six hours. That’s it! No gathering of fuel needed to boil the water. No wait for governments to build or repair water treatment plants. Haiti is just one place on the planet that has great need.
