I'm just getting into fixing my water as well so I don't know much about this subject yet. I would think you would want to get it tested again. The last test was done in 2009 (if I'm reading that correctly). Water profiles can change with the seasons depending on your water source. A 3 year old report could have big changes....as you can see everything went up from 2007 to 2009.
