APPLICATION OF COMBINED GEOPHYSICAL METHODS IN THE EXPLORATION FOR HIGH QUALITY GROUNDWATER IN Fe AND Mn IONS-ENRICHED AREAS
-
Abstract
Fuyuan area of Heilongjiang Province in the east of the Sanjiang Plain is with abundant groundwater resources that meet the local needs of agricultural and domestic water in volume. However, due to the geological environment, the Fe and Mn ion contents is high in the Quaternary shallow water layer, which is extracted for non-concentrated drinking water supply in the area. The over standard water has seriously affected the life quality of residents. In this survey for high-quality water source, the sophisticated methods of high-density resistivity and IP sounding are combined to explore the Neogene aquifer under the Quaternary cover. With exploration and mining, it is proved that the designed combination of geophysical methods is suitable and effective. The test shows that the found aquifer belongs to sodium bicarbonate type with low salinity and weak alkaline, qualified for drinking water standard.
