Ζ Estimate hydraulic conductivity (K) in minutes as opposed to hours for a pump test. This method requires the depression or elevation of static water in a well, and the measurement of time it takes to equilibrate. This is done by inserting a slug into the well causing the water level to rise or by removing a slug causing the water level to fall. Time is measured until the level returns to its original static position. The most common log types used are logarithmic or fast linear. > A well is pumped at different rates for short periods of time, and the aquifers response or drawdown is measured...

Absolute (non-vented) sensors respond to atmospheric pressure and pressure head of water above the sensor. Its measurements are read in psia (pounds per square inch absolute) relative to zero pressure. PSIA sensors must be compensated for atmospheric pressure using a Baro TROLL > ή . Gauged (vented) sensors allows atmospheric pressure to be applied to the back of the pressure sensor, canceling out the effect of external atmospheric pressure fluctuations. Measurements are in psig (pounds per square inch gauged) relative to atmospheric pressure. PSIG sensors must be deployed on vented cable with...
