I used to have stacks of bottled water at home for a variety of uses.
I realize that there is still a use for bottled water, when travelling and in your emergency kit, but I’ve eliminated bottles in daily use.
I volunteer at a festival each year and they’ve been trying to reduce their impact on the earth as well. One of the things they tried was to supply water in bulk and have people bring their own container. Well most people were quite receptive to the idea but there were rules and regulations from the municipal governments. Even though the water was potable, we couldn’t claim it was. The water source would have to be tested and the filling of containers would require procedures to prevent contamination. In the end, we had to supply bottled water.
At home, I’ve been using a Britta. I have been for years but bought a second one to keep up with demand. Water connoisseurs would argue that using a Britta is not the way to go either. They claim the taste needs the minerals that the Britta filters out. The recommended procedure is to let a pitcher stand uncovered for a day or so to let the chlorine evaporate, then refrigerate the pitcher. The pitcher also helps to regulate the fridge temperature.
Now, it’s not only the waste that the bottles produce but there are health concerns regarding the chemical bisphenol A used to make the bottles.
