Abstract:

Cao Bang province is a locality with rugged mountainous terrain and limited water formation conditions, so it is currently facing water scarcity to serve people's lives. Currently, a small part of the water source used for living activities is exploited from drilled wells and dug wells, while the majority of the water source is from springs, streams, rivers and rains. However, the surface water is not enough to supply in the dry season, so the orientation for exploitation and using the groundwater located deep in the fractured aquifer is necessary. According to the survey results, community consultation, sampling and laboratory analysis in 10 highland mountain and water-scarce areas of Cao Bang province shown that with a total quantity for use in the area is 912 m3/day, the quantity of groundwater ensures supply for daily life and socio-economic development activities that without affecting the environment and stability of the region. The water quality in the survey wells is good, only a few areas are contaminated with microorganisms that need to be treated before use. From there, the study proposes solutions for management in exploiting and using groundwater to serve people's lives, ensuring stability and sustainability of water resources for socio-economic development locally.
