Old water tests mean very little. Water changes, the best test method is to have a test done annually and keep the records to see what changes and trends occur. I also recommend having the testing done at different times of the year, again, water supplies change and seasonal differences can be dramatic. A simple example, Norco California, well water system, 53 grains hardness late summer, 120+ grains hardness in the winter. The water testing is the responsibility of the homeowner, and old tests are not usable. I recently got a test and did my analysis, designed the equipment, and as I was about to send off my quote, I noticed the date on the water test was from 1988!!! Now I know better, I always check the date before analyzing it, I just skipped that this time.
