Challenges and Solutions for Sustainable Groundwater Usage: Pollution Control and Integrated Management

Purpose of Review This paper aims to critically review the current status of groundwater usage from the point of view of pollutant control and integrated management. Recent Findings This paper has shown that sustainable efforts must be encouraged to minimize the arsenic content from all the possible sources before entering the groundwater system. Excessive nitrate and pesticide utilization must be significantly reduced for a sustainable environment. Although various in situ remediation technologies are possible to remove some contaminants in the groundwater, the future concern is how it can be carried out in accordance with environmental sustainable goal such as the implementation of in situ bioremediation and bioelectroremediation which provide a cheaper and greener solution compared to physical and chemical approaches. To develop a successful integrated management for a sustainable groundwater usage in the future, conjunctive water management is recommended as it involves the management of ground and surface water resources to enhance security of water supply and environmental sustainability. Summary This paper critically reviews the current state of knowledge concerning groundwater usage from the point of view of pollutant control and integrated management. Information presented in this paper is highly useful for the management of groundwater not only in the quality point of view but also in the sustainable quantity for future development.
