Wait, there's not a pH range limit on drinking water in the U.S.?!
- clayrichardson 11y agoRight? I was thinking that was quite odd as well. I wonder how the current primary and secondary drinking water regulations came to be.
- webkike 11y agoIf I had to take a guess, the EPA probably issues MCLs for acids and bases and not the resulting pH of them combined.
- dnautics 11y agoProbably because distilled water with no buffering salts can have a huge range of pH and is effectively harmless.
