My husband gathered my samples for me yesterday and today, and both times he took water from the pool in two different places than I do, I don't know if this has anything to do with it?
No, just sounds like normal testing variation and error that happens every so often. The fact that you retested and got your 'normal' results confirms this!

One set of out of line test results is nothing to lose sleep over. If they are repeatable THEN your water balance has changed.
