We used the water at LM for cooking ( pasta, rice, etc ) and no problems. Except when it was 17 degrees and it was frozen. We didn't stay overnight at HC so I can't tell you about the water there. It's probably well water since it used to be a ranch. We just use bottled water if it looks or smells weird. Compared to San Antonio tap, well,,,,,,a puddle would be drinkable. Just kidding.
