Is it Safe to Drink Old Water Storage?

When my husband & I moved, it was a good time to empty our water storage containers and refill them after we were settled. It has been 3 1/2 years since the old water storage was emptied and replaced. Over the years, a few of the caps leaked when I recently tested them. I also stored bleach near them and the bleach went bad, foaming out of the container and making a mess next to the water storage containers. These are two potential threats to my drinking water storage so I wanted to test it for bacteria.
Within this article, I’ve conducted 2 separate tests. One on filtered water stored in a blue 5-gallon jug and the other on tap water stored in a sanitized old pickle jar.
