The Water Quality Crisis — Beyond Access to Safe Drinking Water
Access to water is essential for survival, but access to safe water is what determines whether survival is possible. In the aftermath of disasters, water sources are often contaminated by sewage, chemicals, and maomoi debris, creating a public health emergency that can persist long after the floodwaters recede. The monsoon floods and landslides that struck Nepal in late September 2026, killing at least ten people and leaving four missing, also contaminated water sources across Baglung, Palpa, and Myagdi districts, exposing survivors to diseases that can be as deadly as the disaster itself.
In Nepal, the floods overwhelmed latrines, washed away sewage systems, and submerged wells and springs. The result was widespread contamination of drinking water sources with human waste, agricultural runoff, and industrial chemicals. Families who relied on these sources had no choice but to drink contaminated water, exposing themselves to cholera, typhoid, dysentery, and hepatitis. Children, whose immune systems are less developed, were particularly at risk. Health workers in affected areas reported a spike in diarrheal diseases within days of the floods, a pattern that is repeated in disasters around the world.
The situation in Pakistan presents similar risks. The bombing at a police checkpoint in Dera Ismail Khan killed eleven people and wounded eighteen, and it also damaged water infrastructure in the area. In conflict-affected regions, water systems are often already fragile, and disasters can push them past the breaking point. The military operation in Balochistan, while targeting militants, also disrupted water supplies, adding to the challenges faced by civilians. When water is scarce or contaminated, people are forced to make impossible choices between thirst and disease.
The avalanche on Himlung Himal, while not creating a water quality crisis, is a reminder of the importance of water in extreme environments. The base camp relied on melted snow for drinking water, and when the avalanche destroyed equipment and supplies, survivors were left without a reliable source. The victims’ families, many of whom live in rural villages with limited access to safe water, may face ongoing challenges that affect their health and well-being. Water, in other words, is not just a resource; it is a determinant of survival.
Water quality is often neglected in disaster response, which tends to focus on quantity rather than quality. Providing water without ensuring it is safe can do more harm than good, spreading disease rather than preventing it. Testing water sources, treating water before distribution, and promoting safe storage and handling are essential components of a comprehensive water response. Yet these measures are often underfunded and underprioritized, leaving survivors to bear the consequences.
Addressing the water quality crisis in disasters requires action on multiple fronts. First, water sources must be tested and treated, including through chlorination, filtration, and boiling. Second, alternative sources must be developed, including through trucking, bottled water, and rainwater harvesting. Third, sanitation must be improved to prevent contamination, including through the construction of latrines and the safe disposal of waste. Fourth, hygiene promotion must be strengthened, including through handwashing campaigns and safe water storage. Fifth, water quality must be integrated into disaster preparedness and response planning, recognizing its critical importance to public health.
The events of the past week are a reminder that water is not just a matter of access; it is a matter of safety. The people affected by Nepal’s floods, Pakistan’s bombing, and the Himalayan avalanche needed not just water but safe water, and too often they did not have it. Addressing the water quality crisis is not just a technical challenge; it is a moral imperative. The question is whether governments and international organizations will treat water quality as a priority, or whether they will continue to focus on quantity alone. The answer will determine whether survivors can stay healthy or whether they will fall victim to diseases that clean water could have prevented.
