Antimicrobial chemistries: key to clean water

Access to clean water is not just a basic human need; it's a fundamental requirement for survival and sustainable development. The United Nations (UN) Sustainable Development Goal (SDG 6) aims to achieve "clean water and sanitation for all," recognizing the critical role of water in human health, agriculture, industry, and ecosystems. However, a recent UN report underscores the global challenge: 2.2 billion people lack access to clean water, and 3.5 billion people lack hygienic sanitation, highlighting the urgent need for action.


The annual United Nations World Water Development Report, commissioned by the United Nations Educational, Scientific, and Cultural Organization (UNESCO), provides a comprehensive analysis of the current water situation. Released on World Water Day, the report emphasizes the ongoing efforts needed to improve access to clean water and sanitation worldwide. Achieving SDG 6 requires meeting a set of ambitious targets by 2030, including universal access to safe drinking water, equitable sanitation and hygiene, reduced water pollution, and improved water-use efficiency.


Clean water is essential for various purposes, from domestic use to industrial applications. Antimicrobial chemistries, also known as biocides, play a crucial role in ensuring water safety and quality. These chemistries are designed to control the growth of harmful microorganisms, contributing significantly to the provision of clean water. Here are several ways antimicrobial chemistries contribute to clean water:


• Drinking Water Disinfection and Treatment: Antimicrobials like chlorine or chloramine are widely used to disinfect drinking water. They effectively eliminate bacteria, viruses, and pathogens, making water safe for consumption and other uses.


• Water Treatment in Emergencies: During disasters or conflicts, water sources can become contaminated. Antimicrobials help disinfect water, making it safer for consumption when boiling is not possible.


• Biofilm Prevention: Antimicrobials are used to prevent the formation of biofilms in water systems and industrial processes. Biofilms can harbor pathogens and lead to water contamination if not controlled.


• Wastewater Treatment: Antimicrobials play a crucial role in wastewater treatment, ensuring that effluent is disinfected before discharge into the environment, thus preventing public health risks.


• Water Storage and Distribution: Antimicrobials are applied in storage tanks and distribution systems to maintain water quality during transportation, preventing microbial growth and contamination.


• Cooling Tower Maintenance: Antimicrobials are essential for maintaining clean water in cooling towers, preventing microbial growth that can lead to system malfunctions and air contamination.


The increased utilization of antimicrobial chemistries globally is vital as we work towards achieving clean water and sanitation for all. These chemistries, combined with sustainable water management practices, are key to addressing the water challenges facing humanity in the 21st century.


The global goal "clean water and sanitation" is a critical component of the United Nations' Sustainable Development Goals (SDGs). It is officially known as SDG 6 and aims to ensure availability and sustainable management of water and sanitation for all. Here are some additional details about this important global goal:


By focusing on clean water and sanitation, SDG 6 aims to improve health outcomes, reduce poverty, promote gender equality, and protect ecosystems and biodiversity. It is a key driver of sustainable development and contributes to multiple other SDGs, highlighting the interconnectedness of global challenges and the need for coordinated action.
