Piccaso if you go to that website it states that the ph is a non-enforceable guideline. Meaning that the water should be 6.5-8.5 but if it is they dont give a crap and you can complain but they still wont do anything unless your going to sue the city.
Straight form the site:
"National Secondary Drinking Water Regulations (NSDWRs or secondary standards) are non-enforceable guidelines regulating contaminants that may cause cosmetic effects (such as skin or tooth discoloration) or aesthetic effects (such as taste, odor, or color) in drinking water. EPA recommends secondary standards to water systems but does not require systems to comply. However, states may choose to adopt them as enforceable standards."
