Extension Water Storage Info.

Someone mentioned to me today they had heard that water shouldn't be stored in used containers, even if the container had previously contained food and is a food grade container. It was also mentioned that the information had come from the Utah Extension office. So, I thought I would check the source, this time, and see what I could come up with. I found no information stating that it is unsafe to store water in used containers. I also am including the site from the extension with all the water storage info. I would love it if someone would let me know if they find any info. that it isn't safe. Here's the site
