A good pH score depends on what you're measuring. Here's a breakdown for common contexts:
-
For Human Blood: A healthy pH range for arterial blood is between 7.35 and 7.45. This narrow range is crucial for the body's metabolic processes to function correctly.
-
For Drinking Water: The EPA recommends a pH between 6.5 and 8.5 for drinking water.
-
For Swimming Pools: A good pH level for swimming pool water is typically between 7.2 and 7.8.
It's important to note that "good" pH levels vary depending on the specific application.
