Bihar's Water Crisis: Ponds Vanish, Groundwater Plummets

Bihar is experiencing a significant water crisis due to the systematic destruction of its traditional water bodies. Ponds and wetlands, crucial for replenishing groundwater, have been increasingly filled with earth or paved over for construction and agriculture. This loss has severely disrupted the state's natural hydrology and weakened groundwater recharge mechanisms.

Environmental experts note a drastic shrinkage in Bihar's wetland cover over the past two decades. For instance, a major wetland in north Bihar has reduced from nearly 6,000 hectares to under 2,000 hectares, with the exposed land encroached upon. This loss of natural storage systems means rainwater, instead of seeping into the ground, flows away or evaporates.

The problem is particularly acute in urban areas like Patna, Darbhanga, and Gaya, where increased demand exacerbates the situation. Groundwater is being extracted at rates far exceeding natural replenishment, forcing deeper drilling for water. This excessive depletion also leads to a concerning rise in contamination, including arsenic, iron, and fluoride, posing serious health risks to millions.

Furthermore, construction over former water bodies hardens surrounding soil, reducing its capacity to absorb rainwater. The interruption of natural water flow through interconnected water bodies also prevents adequate replenishment, leading to widespread drying and falling groundwater levels across interconnected villages and urban areas.
