CHARAKTERYSTYKA PARAMETRÓW HYDROGEOLOGICZNYCH SZCZELINOWO-POROWEGO ZŁOŻA WÓD LECZNICZYCH W KRYNICY

Abstract

HYDROGEOLOGICAL PARAMETERS DESCRIPTION OF FISSURED-POROUS THERAPEUTIC GROUNDWATER BASIN IN KRYNICAAbstract. Pumping tests were performed in the Krynica Spa during the years 1998–1999. Special equipment was applied during tests as the probe with continuous downhole pressure registration and barometric pressure reduction. As a consequence the effect of different density of the gaseous-water mixture (CO2 + water) has been eliminated. Hydrodynamic tests have been performed in transient nonsteady state conditions. Conductivities of the fissured-porous aquifer have values from 1.25x10-9 to 1.13 × 10-4 m/s. These are of order of magnitude lower than obtained during past traditionally performed short pumping tests. More realistic safe yield of therapeutic waters is a consequence of the performed hydrodynamic tests. Developed methods can be used to overcome similar problems in other fissured-porous aquifers with low permeability.
