Geophysical investigation in contamination hazard studies

The influence of mine water reservoir on the groundwater quality was estimated. The geophysical methods as the electromagnetic and conventional resistivity method combined with elementary hydrogeological techniques were used to mapping and monitoring groundwater contaminant plumes. The investigation area is situated around the reservoir of mine salt water in Upper Silesia, Poland, where groundwater contamination either does occur or may soon occur. First the electromagnetic measurements were carried out to mapping anomaly areas. Then on the basis of geophysical measurements interpretation the proving bore holes were made to measure.groundwater level and conductivity. The conductivity of water from surface seepages, reservoir and neighbouring rivers were also measured. The electromagnetic and hydrogeology results shown the connection of geophysical anomalies with migrated mine water from reservoir. It can enable mapping of the contaminated areas and identify contamination hazards.
