What impact can that have on a typical DR/HA operation?
• Relieves burden on transportation system used to deliver bottled water.
• Transport can then used to move additional food or medical supplies.
• Dramatically reduces waste created by empty plastic bottles which need to be removed and wind up in trash cans or landfill.

Cryptosporidium
• Cryptosporidium is usually connected with poor sanitation. It is a common and difficult problem in developing countries and ranks as a leading cause of diarrheal illness worldwide
• Cryptosporidium parvum is a waterborne parasite encased in a leathery shell, or oocyst, and causes severe flu- like symptoms when ingested
• The only treatment is to let the infection run its course and drink plenty of fluids to restore electrolyte balance to the body.
• Cryptosporidium responds somewhat to chlorine but only in high doses, and it is resistant to many commonly used hospital and laboratory disinfectants
• Typical municipal water treatment plants may not be set up to test for or remove Cryptosporidium.
• To date, it seems Cryptosporidium can only be removed effectively by barrier methods of filtration including ultrafiltration and reverse osmosis.
