Influence of groundwater intake exploitation on degradation of peat soils in river valley
2001
Kowalski, J. | Molski, T. | Moryl, A.
Groundwater intake Keszyce located on the right-bank of the river Olobok valley (Poland) consists of 5 wells, taking off the water from the second aquifer, built-up of gravels and coarse sands with boulders. Groudwater intake wells may be exploitated with maximal discharge 135 cubic m/h. On the side of the river, Keszyce intake is protected from infiltration of contaminated surface waters into aquifer by drainage wells protective barrier, with maximal discharge 25 cubic m/h. As a result of groundwater level depression (on the average 2.5 m), in initial period of intake exploitation, the degradation of peat soils occurring on 2 tested plots has begun. Present return of groundwater level to natural conditions can not turn this process back (unremovable failures)
