How does pH get into the water?
pH does not "get into your water"- it is a measure of what the water IS- acid or alkaline. Materials that make the water acidic or alkaline can enter the water many ways- from pollution that is washed out of the air when it rains, by pollutants that go directly to surface waters, etc. But nature also plays a role. Water that seeps through limestone rock becomes alkaline from the limestone. Water that seeps through plant materials (humus or peat) becomes acidic, since the plant materials are mildly acidic.
