Surface waters typically range from pH 6. Water with a pH less than 6. This water typically is corrosive and soft. It may contain metal ions, such as copper, iron, lead, manganese, and zinc. The metal ions may be toxic, may produce a metallic taste, and can stain fixtures and fabrics. The low pH can damage metal pipes and fixtures. Water with a pH higher than 8. This water often is hard water, containing ions that can form scale deposits in pipes and contribute an alkali taste.

For the pH question- pH is dependent on temperature.

The pH scale actually is based on another scale. We usually keep track of the concentration of solutes in moles per liter M. Since at room temperature in pure water, that concentration is very close to 10 -7 M, pH 7 is neutral. Mike W. That's true. Only H2O? Some of the water molecules fall apart into ions.
