The Savellis purchased a rural house and lot located near the intersection of two highways. Adjacent to the intersection, Carlton Fuels Ltd. had operated a gas bar and service station for many years. Over time, spilled gasoline and other petroleum products may have seeped into the soil. The fuel tanks, however, had been removed some years before the Savellis purchased their home, and the service-station property had been sold to a plumbing-supply company that used the buildings and grounds to store plastic pipe and copper plumbing fittings. Some time after the purchase of their home, the Savellis began to notice a strange taste and odour in their drinking water. Their water supply was obtained from a well on their premises. Tests of the water supply indicated that the water was contaminated by gasoline. Advise the Savellis of their rights at law and the possible course of action open to them.
