NC snow melt

[sandfly]

ground is still frozen no water will fill aquifers. I can only dig down 2" till i hit frozen, water will just run off like its doing now. frost is over 15" deep along pine

5.6 on my hach kit, beth run and n branch bowman (bowman tribs), yesterday. melting snow, this is bottom of my kit's scale may well have been lower.

What technology do people use to measure lower pH levels?

most digital ph meters can read below 5.6 if properly calibrated. For strips you just need to have a lower range set of strips. I am pretty sure there are sets that will read into the 3s.

tb asked about measuring pH below 5.6 (lowest level on my hach #17F 5.6-8.4 kit).

hach has a 4-10 pH kit (= #17N). I like the narrower range one to see more detail under more normal conditions, not so much the extreme acidity levels we just had (snowmelt maybe worst in years).

would have been nice to look for pH not getting quite as low in streams w higher buffering bedrock last few weeks.. a lot of unts just read 5.6. did see a few brookie streams at 6.3 when most hit the 5.6 kit's floor.

brookie stream in a mostly juniata bedrock drainage yesterday, high spring flow 1 day after heavy rain, 6.3-6.4 pH. fished well.
