We bring about ten gallons of really good water from home for drinking, and we don't drink the water in our fresh water tank, for exactly the reason the OP mentions -- you never know what you are going to encounter. Especially when making coffee, the bad water really affects the taste.
Why not fill your fresh water tank at home? If you are connected to shore water in a campground it is not going in to your tank unless you want it to. I always do a taste test before filling my water tank and after it passes it still goes through the filter.
