And so that company monitors this spring weather work comes from they monitor they test the bottles before they go out. Just to make sure that there's no bacteria and it's one of several tests that they have to do. What they're saying is that one of this spring's that they got water from tested positive for E. Coli. Which means that that spring is contaminated with either. Animal waste or sewage and the company said look we don't care where there are treatment got rid of that you know we want to make sure that people are absolutely safe and were recalling that. Water okay. There are lots of different types of E. Coli bacteria. How many of them are actually dangerous how many of these strange actually dangers to human.
