Priest Lake Public Library Water Purification Off-The-Grid

Water Purification Off-the-Grid
Presented by Librarian Robert Borch
Robert Borch, a semi-retired geologist, will give a demonstration of his simple and robust off-grid water treatment method for removing dissolved metals, with an emphasis on dissolved iron, but with applications for other metals of interest locally, especially dissolved uranium, and non-metals such as arsenic.  He has been treating his own water for four years now, for an initial cost of about $60, or roughly three cents per gallon so far.
