- Abstract
In Bangladesh, groundwater is the main source of potable, industrial, and irrigational water supply. Due to its heavy dependence, an excessive groundwater table drawdown and deterioration in groundwater quality is noticeable. The groundwater from ten cities in Bangladesh (Gazipur, Kishoreganj, Rajshahi, Bhola, Khulna, Patuakhali, Lakshmipur, Bagerhat, Chattogram, and Mymensingh) was evaluated for this study. Six groundwater parameters (pH, Turbidity, Chloride, Hardness, Iron, and Arsenic) were assessed to determine the Water Quality Index (WQI) using the Weighted Arithmetic Method. Using this method, it is revealed that the following parameters differ as follows: pH ranges from 6.8 to 8, turbidity from 0.9 to 5.5 NTU, chloride from 59 to 244 mg/L, hardness from 20.3 to 116 mg/L, iron from 0.12 to 9 mg/L, and arsenic from 0.002 to 0.024 mg/L. According to the WQI value, the water quality at the hydro-stations in Bhola, Khulna, Patuakhali, and Mymensingh was rated as “Excellent,” with WQI values of 11.79, 11.19, 8.14, and 15.95, respectively. On the other hand, the water quality of the hydro-stations in Gazipur, Rajshahi, Lakshmipur, Bagerhat, and Chattogram is rated as “Good,” with WQI values of 45.83, 34.96, 38.35, 48.35, and 36.89, respectively. Kishoreganj is the only hydro-station to achieve “Very Poor” water quality, with a WQI of 80.24. The assessment of groundwater test findings will aid in identifying groundwater pollution, which is required to evaluate the risk to public health and provide strategies for protecting groundwater.
