pH meter would not calibrate; however it read the pH7 buffer correctly so we used it uncalibrated.

#11294 17 Jun 2017 Approved Notes:

The pH meter would not calibrate. So I read the values of the two pH calibration standards and found the meter reading 0.2 pH units high. So we deducted 0.2 units from each sample reading and recorded these as the "corrected" values.

pH meter was accidentally left at home, so no pH readings were recorded for today's sampling.

Volunteer Arley (Jennings??) assisted today' sampling.
