title: PUBLIC WATER SUPPLY CONTAMINATED BY AN INTERCONNECTED PRIVATE WATER SUPPLY.
abstract: Private water supplies connected for emergency purposes to public supplies are a potential source of pollution. Check valves which a decade ago were considered safe have been subject to such changes in design as to be now condemned. Health officers should be on their guard against any commercial economy here that means health risk to their communities.
