Bob, A plug of avgas can be sent through the pipeline. They may have a big ball at the beginning and end of the plug of avgas, I don't know. I do know that when they send avgas through a pipeline, the ends of the avgas plug get contaminated with the fuel adjacent. I've seen articles saying that half the avgas shipment may have contamination and can't be used for aviation fuel. How much contamination allowed is probably specified. This has a lot to do with the cost of avgas. Other areas may ship their avgas entirely by tank car or truck. But then, the fuel is put in a tank. Then it's put in a tanker truck. What was in those tanks and trucks before? How perfectly empty was it? I don't know. I would, in your situation, take an olive jar, some water, a marker and do the test. Put an inch of water in the olive jar, mark the line with the marker, fill the jar with fuel from the pump, put on the lid and shake it. If the "water" level line changes, you had either water or alcohol in the fuel.
