Groundwater control refers to the management and regulation of underground water resources to prevent issues such as flooding, erosion, and contamination. This process involves techniques like drainage systems, pumping, and water table monitoring to maintain the desired water levels and quality in aquifers. Effective groundwater control is essential for sustainable water supply, especially in areas reliant on wells and springs. It helps protect ecosystems, supports agriculture, and ensures safe drinking water. By implementing proper management practices, communities can balance water use with environmental conservation, promoting long-term water availability.
