I use Magnesium Oxide (MgO) prill beads to purify drinking water in Hawaii. 

The prill beads come from a deep mine in Nevada. They are processed at 700 degrees which turns them into ceramic beads that do not dissolve in water.

The beads place a positive charge in the water that shatters the magnetic bond that holds together any contaminants or pollutants (chlorine, fluoride, heavy metals: zinc, copper, lead, chromium-VI, pesticides, radiation, pharmaceuticals, mold, Ecoli, bacterias, etc) and gasses them out of the water. It raises the water pH to 8.7, high alkalinity, high oxygen, and thins the water so that can penetrate the cell membranes and flush out your toxins. 

As to hydration: 3 glasses of prill water is equal to drinking 1 gallon of reverse osmosis water.

Typically these bags are used in 3 gallon containers with spigot at bottom. 

If you can get a community tank that is fille d by a source of water where people could fill their containers, it would work. 

These beads last forever, therefore, NO ongoing costs!
