My brother had just recently renovated his place and the nearest restroom from the living room was in the basement, down through a door in the garage. When I got to the bottom, water was flooded up above my ankles. After using the toilet and washing my hands, I filled up a bottle of water but decided to only drink it if it seemed safe to drink when I brought it up to the first floor. I picked up a clear bag of trash before heading up. As I climbed the stairs, I noticed the steps were strewn with fish-tanks on their sides and pools of dead fish.
