This current investigation has been aimed in the estimation of the present status of physico-chemical
characteristics of tube wells (TWs), shallow wells (SWs), and Helmand River water (HRW) in districts 1, 2, and
3 of Lashkar Gah city, Helmand, Afghanistan. The physico-chemical parameters like water temperature (Temp.),
electrical conductivity (EC), pH, total dissolved/suspended solids (TDS/TSS), turbidity, total hardness (TH), total
alkalinity (TA), nitrates, sulfate, chemical oxygen demand (COD), salinity, chlorides, magnesium (Mg), calcium
(Ca), and ammonia were determined and statistical analysis has been performed. The analysis was performed
with a (16×16) correlation matrix between water quality parameters with an intension to minimize the
intricacy and understanding the large data set. The significant correlation was tested by applying the t-test.
Parameters were compared with their permissible standard limit as described by the World Health
Organization (WHO) and international agencies. The water quality index (WQI) revealed that water samples
were in the classification of very poor, poor, and good quality. The water samples were classified ranging from
very poor to good quality defined as the WQI
