Water problems are not interchangeable. A leak inside your home, a public supply interruption and a problem with a private source each need different information. These guides help you distinguish them and plan access to safe water, including the work of collecting and carrying it. Treatment claims deserve particular care. Start with the water supplier or regulator responsible for your area and follow any notice that applies to the actual incident.
