The invention describes a method and apparatuses for characterizing groundwater measuring sites by differentiating between groundwater and static water and serves, for example, for determining the pumping-out times of groundwater measuring sites, optimum for investigations of the representative nature, as well as for identifying and localizing defects at groundwater measuring sites. The invention is based on measuring the radon activity concentration or the total activity concentration of the groundwater samples. The measurement of the concentrations by offline or online methods permits the ratio of groundwater to static water in a groundwater measuring site to be determined reliably. A novel flow-through measurement cell, as well as a borehole probe are described The invention can be employed wherever investigations of the nature of groundwater are carried out.
