 This is going to be the first time and perhaps the last time that you'll ever hear this on national radio. The Berkey water filter ate my homework. I kid you not filled up the Berkey water filter last night. I had all of my research on the counter and it was all soaking wet and I couldn't understand a word in any of it. So I'm going through a lot of this stuff from memory and with the help of Tracy's notes and some that I was able to reprint.
