Can you imagine just how many children this elder in the village
must have seen die of dysentery, a waterborne disease
that the WAPI could have prevented.
   The WAPI, Water Pasteurization Indicator, provides distraught communities with a potential solution to their need for water purification. The reusable WAPI, a small colored piece of wax in a polycarbonate tube, is placed in a pot of water, juice, or other milks. When the wax is heated to the pasteurization temperature, 149°F / 65°C, it travels to the bottom of the tube. This is an indicator that the liquid is free from harmful bacteria.
Thanks to the WAPI,
life is changing for the better on Planet Earth.
