Geoecological factors of soil and groundwater contamination with chlorides in the zone of impact of halite waste storage facilities
Abstract
The main factors of halite waste storage impact on groundwater quality and soil salinity in technogenically disturbed ecosystems are considered. It is shown that groundwater salinisation is most intensive in the immediate vicinity of halite waste storage sites, but the chloride content increases with time. The main factor determining the spread of salinisation is the flow direction to the north and east to the Sivelga and Sluch rivers. The content of chloride ions in the soil was found to decrease with distance from the heap and in the soil horizon, but even at a distance of 300 m it remains high enough, which allows us to attribute the soil to a high degree of salinisation. In model experiments the positive effect of peat application of different degree of decomposition on soil acidity and reduction of chloride content by 27–37 % was shown. Among tested agricultural crops the greatest tolerance to chloride content in soil was possessed by beetroot, barley and bluegrass.
