pH
What You May Notice
Above EPA's secondary standard, pH can cause: low pH: bitter metallic taste; corrosion high pH: slippery feel; soda taste; deposits.
EPA regulates pH under a secondary drinking water standard — a non-enforceable guideline set for taste, odor and appearance rather than health. Water systems are not required to meet it, and exceeding it is an aesthetic problem, not a known health risk.
