Assessment of Water Quality for Drinking and Domestic Use from Three Sources in the Mila Region,Northeastern Algeria

This study evaluates the suitability of water from three natural sources in the Mila region of northeast Algeria for human consumption over three months (February-April 2023). It compares physicochemical parameters with Algerian (AS) and World Health Organization (WHO) standards and calculates the Water Quality Index (WQI). Results show that while all parameters met Algerian standards, some exceeded WHO standards, particularly EC, TDS, and Si(OH)₄. WQI values ranged from 43.64 to 86.19, indicating water quality varied from good (78%) to excellent (22%). Although the water is generally suitable for consumption, daily chlorination is recommended to maintain safety. The study highlights the need for ongoing water quality monitoring to protect public health and preserve natural spring waters in Algeria.
