Today I learned that California has at least one business that can be called a "water store". Obviously, the chemical that's in the water that must promote such enterprises has to be reintroduced after any purification processes that may occur in the aforementioned store. Someone please explain to me how such a business is viable in 5 gallon quantities, when the rest of the world either digs a well, buys the outflow from a metered pipe, or fills up a cistern from a tanker truck with at least 3000 gallons per delivery. Do they not sell reverse osmosis filters or distillery pots there? Also, if one person filters out the stable perfluorocarbons like PFOA and PFOS, and then dumps them back down the drain again, is that really helping to solve the problem?
