FYI- I always thought rainwater was a little acidic, last week I ph'd the rain at 8.8, thought I fucked up. Calibrated pen and collected rainwater again last night and still ph'd right at 8.8. WTF?

Yeah, I use my ph meter alot so I always calibrate to 7 and 4ph. I'll keep working on it. Puna Bud, what does your catchment usually ph at?
 
Arrowhead bottled water has a ph of 7.0~7.1., and it seems to have the most consistent ph levels of all the bottled water out there The tap water on Oahu is around 7.0 (can very)

I collected a rain water sample last night and it registered 7.0 on my pen.
Maybe the container you are using to collect your rain water is cross contaminating with the rain water giving you such odd pH #'s

ahaha maybe your pen only shows neutral ph.
 
Yeah, think it's something I'm doing. My tap water is usually between 7.5 and 8.2. The local stream is always flat. Maybe my windward neighbor is a coke dealer and stomps on it with baking soda. ha
