groundwater recharge influenced by anthropogenic scenario along with the sources of water pumping

Introduction

Groundwater recharge and its dynamics are significantly influenced by anthropogenic activities such as groundwater pumping, wastewater discharge, and water transfer. Understanding these influences is crucial for effective water resource management and environmental sustainability.

Key Insights

Artificial Water Recharge:
- Artificial surface water, including discharged wastewater and transferred water, has become a major recharge source for local groundwater due to the decline in groundwater tables .
Groundwater Over-Extraction:
- Over-extraction of groundwater leads to significant changes in groundwater flow patterns and chemistry, often causing vertical mixing between aquifers and altering the natural hydrochemical processes .
Impact on Elemental Cycles:
- Intensive groundwater pumping significantly contributes to global anthropogenic element cycles, affecting the flow of elements crucial for industrial and agricultural development.
Hydrochemical Changes:
- Anthropogenic activities, including groundwater pollution, excessive exploitation, and recharge, are major factors influencing groundwater chemistry, often leading to increased mineral dissolution and ion exchange .
Climate Change and Groundwater Pumping:
- The combined effects of climate change and groundwater pumping result in reduced water availability, soil moisture, and aquifer responses, exacerbating the impacts on water resources.
Groundwater-Surface Water Interaction:
- The interaction between surface water and groundwater is significantly altered by anthropogenic activities, with artificial water sources becoming dominant recharge contributors and affecting the spatial distribution of groundwater recharge .
Seasonal and Spatial Variability:
- Groundwater quality and recharge sources exhibit significant seasonal and spatial variability, influenced by both natural factors and anthropogenic activities such as irrigation and land-cover changes .

Conclusion

Anthropogenic activities, particularly groundwater pumping, wastewater discharge, and water transfer, have profound impacts on groundwater recharge and chemistry. These activities alter natural groundwater flow patterns, contribute to global elemental cycles, and exacerbate the effects of climate change on water resources. Effective management strategies must consider these influences to ensure sustainable water resource utilization and environmental protection.
