Immission pumping test

from Wikipedia, the free encyclopedia

An immission pumping test is a hydrogeological field test to determine the mass flow of a target substance through a control level in an aquifer .

Groundwater is pumped in one or more wells for several days. The pumped up groundwater is sampled several times during the pumping measure and the concentration of the substances to be examined is determined, such as pollutants from groundwater contamination . By evaluating the resulting concentration curves, it can be determined how high the mass flow of the examined substance is through the corresponding control level. The concentration curves can be evaluated using various methods, for example a transient inversion algorithm that was developed at the University of Tübingen .
