Monitoring the quality of drinking water is essential for ensuring the health and safety of the population. Standards set by the World Health Organization require that drinking water should not contain more than 50 mg/l of nitrate, 250 mg/l of chloride, 0.3 mg/l of iron, and 0.5 mg/l of ammonia. The pH of water should be in the range of 6.5-8.5. Regular monitoring is necessary to ensure the absence of coliform bacteria
