Effective Groundwater Monitoring Using Dedicated Pumping Tubes

 This article describes a groundwater monitoring procedure that does not require decontamination of pumping equipment, eliminates the chance of cross contamination between wells, and uses a surface pump. Two surface pumps are described, one for water level depths less than 25 feet and one for water level depths greater than 25 feet.  ●   Install Dedicated Pumping Tubes   A dedicated pumping tube (1/2” black irrigation hose)...


Constant Rate Aquifer Tests Using Wellhead Mounted Pumps

This article describes how to conduct drawdown and buildup tests for the determination of aquifer transmissivity using surface pumps whose design permits the flow rate to be precisely controlled....
