I just received the results of my water testing from the Special Pathogens Laboratory in Pittsburg. Interestingly, my water does NOT contain avium, which I have; however, it does contain gordonae. Does anyone out there have that one? Is the treatment the same as avium? Has anyone tried copper faucets and shower heads and do they even make a difference? Also, I believe it was mentioned somewhere in an earlier post, but what kind of medical grade filters are people using and where do you get them? I understand that my best defense is a healthy immune system that can handle whatever I encounter, but if there are any steps I can take to give myself an edge, I will try those too. Thanks to all!
