Impact of Tap Water Conservation in a Clay Jar: Microbiological and Physicochemical Evaluation after 24 Hours

Access to clean and uncontaminated drinking water is essential for preventing waterborne diseases, which remain a significant cause of morbidity and mortality, particularly in low-income and developing countries. In regions lacking modern refrigeration or water treatment infrastructure, clay jars are traditionally used for water storage due to their natural cooling properties and partial filtration capabilities. This study aims to evaluate the impact of storing tap water in a clay jar for 24hours, focusing on two primary parameters: microbiological and physicochemical stability. Physicochemical Analysis: Seven physicochemical tests were conducted in accordance with the procedures and sampling conditions outlined by the National Office of Drinking Water (ONEP). The analyses adhered strictly to established protocols to ensure the reliability and reproducibility of results. Microbiological Analysis: The microbiological evaluation was performed using the filter culture method, enabling quantification of bacterial colonies in the water sample. This approach provided insights into the total microbial load and potential contamination. Results support the use of clay jars as a natural and effective way to store drinking water, particularly in domestic or rural environments where access to modern water treatment methods is limited. Conclusion: Storing water in a clay jar has significant benefits for its quality, which supports some of the claims and hypotheses widely shared on social media and websites. The reduction of chloride and sulfates, the stability of pH, as well as the inhibition of microbial growth by cooling and provide a scientific basis for the benefits associated with clay jars for purifying and maintaining the freshness of water.
