This research has analyzed, evaluated ground water salinity in Hau Loc district, Thanh Hoa province by determining the concentration Chloride-Silver nitrate titration with Chromate indicator (MO Method) and establishing a zoning map of salinity. The results showed the groundwater at researched areas was being saline over the allowable standards many times. The highest salinity concentration of Cl- exceeded 15 times the allowable standards. This study consequently proposed some solutions for efficient using of water and reducing the groundwater salinity level in the region. |
