・ Longview city drinking water: Safety has been maintained. The drinking water source is a deep underground aquifer located approximately 200 feet (about 60 meters) below the surface. In the event that any signs of contamination approaching the public water system are detected, an automatic response and shutdown mechanism is in place on the public water system side, which is monitored 24 hours a day.
