Borehole pumping and interaction tests can be used to determine the groundwater yield of a borehole. By monitoring the variation in groundwater level in nearby boreholes during pumping tests, the hydrogeological structural connections of the rock between boreholes can be determined.
Pumping tests provide direct information on the hydrogeological structures of the rock, the connections of the structures and the flow in the rock, and produce data to support hydrogeological modeling.
The measurement is performed in defined boreholes and the boreholes are also defined for the pumping period, where the groundwater level is monitored during pumping. The duration of pumping is always determined according to the objectives of the study, but it is also affected by the water yield of the borehole. On average, pumping tests last one to three weeks per hole and pumping. Pumping and water level monitoring are performed around the clock.
Pumping equipment is always selected individually according to the objectives of the study and the expected water yield. Submersible groundwater pumps are generally used. Geovisor has excellent connections with equipment suppliers and equipment rental companies and an extensive cooperation network. Our personnel have diverse experience in various hydrological interaction experiments.
The customer always receives quality-certified raw data from the measurements. In addition, we process, analyze and report the data in accordance with the agreement.
The selected level of reporting and the customer's familiarization with the research results are done as agreed.
