Mineral Fortification and Hydrochemical Shifts in Drinking Water Stored in Traditional Clay Containers (Matka)

This research investigates the hydrochemical changes that occur when water is stored in traditional mud containers (matkas). Unlike steel or glass containers, mud vessels are porous and contain naturally occurring minerals that gradually dissolve into the stored water. Over time, this process enriches the water with elements such as calcium, magnesium, potassium, chloride, and various alkaline compounds. These minerals are essential for human health, contributing to bone strength, electrolyte balance, and improved hydration. The study was conducted using reverse osmosis (RO) water as a baseline, ensuring an initial sample with minimal mineral content. Water was stored in mud containers for 24 and 48 hours, and tested for total dissolved solids (TDS), pH, temperature, hardness, and specific mineral concentrations. Results demonstrate a consistent increase in calcium, magnesium, and chloride, alongside measurable changes in alkalinity and TDS. These findings suggest that the cultural practice of using matkas is not only environmentally sustainable but also beneficial for improving the nutritional quality of drinking water in households.
