Thank you, Georgia Saint, for all the information. Will look into all of it and consider what is best for our situation. We already have a Big Berkey but have not used it yet. Also just purchased a 250 gallon used food-grade tote for storing water–formerly held castor oil and now have to clean it out. Has a large opening in the top (6″) and a spigot at the bottom. Slowly getting there…

BTW our little apple tree, planted last year, has 3 ripening apples. The other 2 blew off in an OK windstorm two weeks ago. A good start. We planted a Yellow Delicious since they are self-pollinating.
