Three day hiking and backpacking trip. Saturday mid day we had exhausted the 2 liters of potable water we each brought and changed over to filtered and treated creek water. No issues Saturday afternoon or Saturday night, but Sunday afternoon when I walked in the house headed straight for the bathroom and BOOM!!!!!! That was it though. No other bad water like issues. Glad I made it home for that. Would have been a lot of falllout debris all around trying to blast that in to a cat hole hahahahaha!
