Ken Larsen's web site - pH levels of water
In November of 2018 I bought a digital pH meter to help me understand whether water in my community (Chapel Hill, NC) is acidic or alkaline ... and by how much.
Here's what I've learned thus far:
|Tap water from OWASA||8.47||Alkaline||November 18, 2018|
|Water from Booker Creek||6.80||neutral||November 18, 2018|
|Rain water||5.37||acid||November 24, 2018||It rained heavily today. The rain was acidic, but not low enough to be characterized as "acid rain". The U.S. EPA says that 5.6 is normal. See their chart, below.|
The digital pH meter cost me $ 12 from Amazon.
