Two billion people don’t have safe drinking water, Pg7

Context: 

• The article highlights the global water crisis where two billion people lack access to safe drinking water, resulting in adverse health outcomes and developmental setbacks.

Key Highlights: 

• Only 156 million rely on surface sources like rivers and lakes.
• Around 75% of the affected population uses water that is improved but not always safe or readily available.
• Unsafe water leads to over 800,000 deaths annually due to waterborne diseases.
• In some low-income countries, over 5% of all deaths are linked to unsafe water.
• Extending water supply to individual households remains a major infrastructural challenge.

Detailed Insights

• The global metric shifted in 2017 from "improved water access" to "safe drinking water", defined by quality, availability, and proximity.
• Water may be initially safe but becomes contaminated during transport or storage, especially when collected from community sources.
• Diarrheal diseases, cholera, polio, and malnutrition are major outcomes of unsafe water.
• The burden of collecting water falls disproportionately on women and children, impacting education and livelihoods.
• Most countries have achieved improved water access, but ensuring household-level safety remains a challenge.
• Achieving universal access requires not just infrastructure but monitoring and maintenance of water quality systems.

Way Forward: 

• Strengthen water quality monitoring and regular testing at both source and point-of-use.
• Promote community education on safe water handling, storage, and hygiene practices.
• Implement affordable household water purification technologies in vulnerable regions.
• Enhance coordination between government, NGOs, and international agencies for funding and technical support.

Key Concepts Involved: 

• Safe Drinking Water: Water that is uncontaminated, available on premises, and accessible when needed.
• Point-of-Use Safety: The concept that water must remain uncontaminated until the moment of consumption.
• Pathogen Contamination: Ingress of disease-causing organisms into stored or transported water.
