We here on the West side of the Cascades are fortunate to have a ready supply of water available should things get out of hand. Always a good idea to filter any water and since I can't afford (cheapskate) a Berkley Filter System, I found a site that shows how to build a low cost water filter. Expedient Family Survival Water Filter . I noticed my local Home Depot has the same buckets in the photos. I bought my buckets at WinCo along with the Gamma Seal lid. Waiting on the delivery of the filter and extra cartridge. Hope it gets here before things explode in the Middle east.
