Water-service contamination at RV parks is always a concern of mine. Some campgrounds have the water service next to the sewer outlet. Being an engineer, I can’t understand why this is legal. To sanitize the water-service hose bib at all parks I carry a bottle of bleach and water solution (1 tablespoon of unscented bleach to 1 gallon of water) and flush the hose bib and open the water valve prior to connecting my service hose and filter.
