pH measures how acidic or basic the water is. The secondary range (6.5 to 8.5) keeps water from tasting off or being corrosive to plumbing.
In Florida, pH was reported by 879 community water systems serving about 4,132,269 people. Every reported reading was at or below the federal legal limit.
Where it comes from: Natural water chemistry; treatment.
Enforceable. A utility must stay at or under this.
Health-based, not enforceable. Often lower than the limit, sometimes zero.
California has not published a PHG for this substance.
Health effects the EPA associates with it: Not a health concern within the normal range. Low pH can be corrosive to pipes; high pH can taste bitter or feel slippery.
Water at or under the legal limit meets federal safety standards. A reading above a health goal is not the same as being unsafe, and health goals are set purely on health without regard to cost or treatability. Both are shown so the margin is visible either way.
