80% of Pakistan’s Groundwater is Unsafe to Drink

Pakistan's groundwater crisis has reached alarming levels, with 80 percent of the nation's groundwater deemed unsafe for consumption. This dire situation is a result of an uncontrolled network of over 1.5 million tubewells, with annual extraction outpacing natural replenishment. Pakistan is the fourth-largest global consumer of groundwater, extracting 65 cubic kilometers annually versus a mere 55 cubic kilometers of recharge.

The Pakistan Institute of Development Economics (PIDE) report highlights that nearly 60 percent of irrigation, 70 percent of drinking water and virtually all industrial activities depend on this dwindling resource. The crisis is exacerbated by the presence of dangerous arsenic levels in groundwater, impacting up to 60 million people, and salinity affecting 21 percent of irrigated land.

The study titled "Pakistan's Groundwater Crisis: Policy Lessons and a Framework for Sustainable Resource Use" states that the problem is primarily a result of flawed policies and governance rather than a physical scarcity of water. Despite having the storage capacity of around 50 large dams, historic policy biases have favored surface-water planning, treating aquifers as open-access resources.

Subsidised electricity for tubewells and price supports for water-intensive crops have led to over-pumping, especially in Punjab which extracts about 90 percent of the country's groundwater. As a consequence, water tables are dropping by one to three feet annually in major cities and agricultural regions. Pakistan's unique predicament is that it is the world's largest exporter of depleted groundwater used in exports like rice, leather and textiles, representing 29 percent of global trade in goods produced from overabstracted aquifers.

To avert a "point of no return," the PIDE report proposes a three-tiered action plan. Immediate steps within the next two years involve licensing and metering all extraction points, eliminating distortionary electricity subsidies and establishing a National Groundwater Council. Over the next two to five years, reforms should include revising water pricing to reflect actual scarcity, shifting agricultural demand towards less water-intensive crops, and implementing a National Aquifer Mapping Programme for real-time monitoring.

Beyond five years, long-term solutions will focus on dismantling colonial-era water rights tied to land ownership, investing in Managed Aquifer Recharge and wastewater treatment, and integrating groundwater governance into regional transboundary agreements. Without decisive political action and coordinated governance reforms, Pakistan risks permanently damaging its economic stability, public health, and resilience to climate change.
