If the gasoline appears cloudy, or if it separates into visible layers, it probably contains water. Contact the station operator. Most operators will be happy to work with you if the contaminated product came from their station. An investigator will be sent out to test the tanks and to collect samples for laboratory analysis. Make sure to call the Division as soon as possible.
Most stations receive fuel shipments several times a week.
It is best if the investigator can collect samples before another shipment has arrived. The investigator will contact you with the test results. In some cases the investigator may request a sample of the gasoline you drained from your tank. If the station's product was not contaminated with water, the problem may lie with your vehicle tank. Tanks which are allowed to sit empty over the winter, or tanks with missing or improperly fitting gas caps may collect water.
