Don’t know if this topic has already been beat to death but here goes. When I walked CF this Spring there were several peregrinos and even an albergue volunteer who said that it was well-known that some of the tap water in towns between Burgos and Leon is contaminated. This came up when a very fit and very healthy friend came down suddenly with a “stomach flu”. She was taken to the hospital in Burgos and given IV hydration and meds. She recovered and in 3-4 days was back on and finished. I was just wondering if people were just talking about the water or if this truly is a thing?
