ASSESSING THE GROUNDWATER SALINITY IN HAU LOC DISTRICT, THANH HOA PROVINCE FOR PROPER MITIGATION MEASURES

Tóm tắt

Water is a vital resource for the survival and development of humanity. However, this resource is not endless. Today, water demand for domestic use and production is increasing in the context of climate change, natural disasters and pollution, significantly causing the depletion of water resources both in terms of quantity and quality. 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.
