1Reported field conductivities for all water quality data collected by
PCC personnel are not corrected to 25°C.
2The field conductivity meter used is a Yellow Springs Instrument Model
33; correction facto r5 were empirically determined in the lab using a
Hach NaCI Standard Solution of 1990 umhos/cm at 25°C.
