Martin, I have a related question for you. When you recommend testing several times throughout the year, are there any indicators as to when? I'm mostly thinking about my water system, which uses a mixture of Illinois River water and three wells. Are there any times I should suspect my supply is changing source, like after significant rain?
I know Jamil has recommended the Lamotte testing kit. It might not be too bad over the long run at $120 for the basic vs. $28/ Ward Labs. Follow up for Martin, which tests tend to be inaccurate for the home testing kits? Any recommendations for kits?
