Groundwater resources
Groundwater resources refer to the water stored beneath the Earth's surface in underground aquifers, porous rock formations, and soil layers. These resources are crucial for various human activities such as drinking water supply, agriculture, industrial processes, and sustaining ecosystems.
Here are some key points about groundwater resources:
Storage: Groundwater is stored in underground reservoirs called aquifers. These aquifers can vary in size, depth, and permeability.
Recharge: Groundwater is replenished through natural processes such as precipitation, infiltration, and surface water runoff. The rate of recharge depends on factors like climate, soil type, and land use.
Extraction: Groundwater is typically extracted using wells. Pumping water from wells can lower the water table and deplete aquifer reserves if extraction rates exceed recharge rates.
Quality: Groundwater quality can vary depending on factors like geology, land use, and pollution sources. Contaminants from agricultural runoff, industrial activities, and urban development can affect groundwater quality.
Management: Sustainable management of groundwater resources involves balancing extraction rates with recharge rates to prevent depletion and maintain long-term availability. This often requires monitoring, regulation, and conservation measures.
Challenges: Groundwater resources face various challenges, including overexploitation, contamination, subsidence (sinking of land surface), and the impacts of climate change such as altered precipitation patterns and sea-level rise.
