The Emergency Water Test Kit lets you screen your tap or stored water at home after a flood, a main break or a boil-water notice, so you have information instead of guesswork. A test kit tests water. It does not treat it, and a test result never makes unsafe water safe. Consumer screening kits do not detect bacteria, viruses or protozoa. If your utility has issued a boil-water notice, follow it regardless of any result you get here.
