I recently met someone who tests city water throughout the country and he told me that our water is very good quality. I told him that I won't drink tap and he said there are stricter rules will tap than bottled. I still will only drink bottled

That said:

These four cities have fair-to-substandard drinking water:

Atlanta, which maintains its distribution system poorly
Albuquerque and San Francisco, which have poor treatment systems
Fresno, which has no real source water protection

Reports from Atlanta, Boston, Fresno, Houston, Newark, Phoenix, Seattle and Washington, D.C. included false, unqualified or misleading claims, or buried crucial information about problems deep in their reports;


Reports from Newark, New Orleans and Phoenix included incorrect or misleading data -- or omitted it entirely;


Albuquerque's groundwater is becoming seriously depleted; Fresno's groundwater is highly susceptible to contamination;


In Atlanta, Chicago, Detroit, Houston, Los Angeles, New Orleans, Newark, Philadelphia, Phoenix, San Diego and Washington, D.C., source water is threatened by runoff and industrial or sewage contamination;


Water supplies in Baltimore, Fresno, Los Angeles, New Orleans, San Diego and several other cities are vulnerable to agricultural pollution containing nitrogen, pesticides or sediment;


Denver's source water faces an additional challenge from debris from wildfires and sediments from floods;


Manchester's problems apparently come from recreational boating activity in its reservoir.
