We need TWO electrodes, because the open signal is POTENTIAL (V), we need the difference of potentials between the two electrodes. o One is the reference electrode and the other is the working/indicator electrode. WebbThe potentiometric surface of the Catahoula aquifer was constructed by using the altitude of water levels measured at 29 wells during the period May through September 2013. The altitude of water levels ranged from 0.02 ft above the National Geodetic Vertical Datum of 1929 (NGVD 29) in well Co-51 to 238 ft above NGVD 29 in well Na-317. greene county health department job openings

WebbWater flow rates and potentiometric surfaces (or piezometric levels) were inferred from drill stem test information acquired from McAllister and Associates of Calgary. Only tests with water recovery were considered after discarding misruns and unsound tests. The flow rates were estimated on the basis of a drawdown of 300 m. WebbThe water table is the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with water. [1] It can also be simply explained as the depth below which the ground is saturated. The water table is the surface where the water pressure head is equal to the atmospheric pressure ...
