The present study investigates the influence of a static magnetic field on the physicochemical properties of piped tap water in Basrah province, southern Iraq. Water was exposed to a permeant neodymium magnet producing an approximately 0.2 tesla field oriented perpendicular to the flow. Exposure durations were instant 5, 10, 15, 60 and 120 minutes, and the distance from the magnetic source was varied (25-100 cm). Parameters including pH, total dissolved solids (TDS), electrical conductivity (Ec), dissolved oxygen (DO), total hardness, total alkalinity and temperature were measured in accordance with APHA standards methods. Results were compared against the world health origination (WHO) guidelines for drinking water quality (2017). Overall, pH remained within the preferred WHO range (6.5-8.5). Electrical conductivity (Ec) and total dissolved solids (TDS) decreased over time, indicating reduced mineral impurities. Total hardness and alkalinity decreased after prolonged exposure, supporting the effectiveness of this technology in reducing scale deposits in pipes. Water temperature decreased from 35°C to 22-26°C over time, indicating greater physical stability. The findings suggest that the magnetic treatment can be considered a supportive, non-chemical option to enhance selected water quality indicators in Basrah province.
