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:
| Source | pH | Type | Last taken | Comments |
| 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. |
| Snow | 4.55 | acid | December 10, 2018 | 4" of snow fell on my property. |
The digital pH meter cost me $ 12 from Amazon.
