Positive impact:
- Recharge: Recharge replenishes the amount of water stored in aquifers, helping to maintain and restore water levels and quality.
Negative impact:
- Groundwater pollution: Groundwater pollution can contaminate aquifers, making the water unsafe for human consumption and detrimental to the ecosystem.
- Excessive pumping: Excessive pumping can lead to the depletion of aquifers, causing water levels to drop and potentially leading to water shortages and sinkholes.
