Pumping Tests

Short-Term Pumping Tests: 

  Duration of up to 24 hours, suitable for quickly assessing groundwater conditions and providing initial estimates of hydraulic conductivity.

Long-Term Pumping Tests: 

  Duration of several days, continuing until a steady-state condition is achieved. These tests provide detailed information on long-term groundwater conditions and allow for a more precise determination of the hydraulic conductivity (Kf value).

Objectives of Pumping Tests 

– Determination of the aquifer’s hydraulic conductivity (Kf value) 

– Analysis of drawdown behavior and recovery rates 

– Assessment of the permeability and storage properties of the aquifer 

Execution of Pumping Tests 

– Installation of a pump in the borehole 

– Continuous measurement of flow rates, water levels, and drawdown 

– Monitoring of fluctuations and stabilization of the water level 

Data Evaluation 

– Analysis of drawdown and recovery curves to calculate hydraulic parameters 

– Preparation of charts and reports to document the results
