Additional Tasks

Water table depths (decimal feet from top of well casing)

Note: Outside wells require regular screwdriver to open cap

If Swapping Li-7500 Analyzer

Remove SN#

Install SN#

Indicate which ditches are full (copy and paste the red cross on the ditch number)

Other Notes:

laser calibration : 80-90 ppb off-set, probably because the mirror-time is decayind so fast
