The two major direct and indirect receptive medium of percolating water that arises in
the course of the utilization of thermal water are soil and surface water (desiccating
lakes, natural streams). The high total salt and sodium content of percolating water
arose in the course of plant operation may cause the direct and indirect damage of
ground water and surface water. Percolating to the ground it may change the physical
and chemical features of the soil. The resulting environmental damage can be very
serious if it takes place in an important sensitive area.
We examine the environmental effects of percolating water emitted by Zalakaros
Thermal Spa at our university since 2003. The surface streams of the sample field are
collected and led by Kiskomáromi-channel to the most significant nature reserve of the
Kis-Balaton reservoir. To our current survey we marked out six sampling and checking
points in the territory of Kis-Balaton Minor and along receptive channels. We took
water samples once per month, on the same days and we determined the most important
water quality parameters on the basis of Hungarian standards. We present the total salt,
sodium and chloride ion content of the analysed water samples and their spatial and
time changes in our poster.
