Never really knowing about the water conditions, we always carry bottled water to drink, and use the CG water to cook and bathe with. It gets boiled on the stove or in the hot water heater. Getting a bug in the gut on a trip is no fun. I caught the Norovirus last year, and I was not even on a cruise ship. Got it from a fast food joint, it was no fun. My son disconnected his RV water from a CG after a weekend, and his hose screen was filled with little critters. I now run the water for a bit before hooking up. The valve is three feet down in the ground not at the top of the spigot, so who knows what crawls into the spigot end when not being used over the winter.
