Elemental Distribution Of Groundwater Of Babugonj Upazila In Bangladesh And Their Suitability Asessment For Multipurpose Use

An investigation was conducted to evaluate the water quality of some ground for irrigation, drinking and livestock consumption. Fifteen samples were collected from Babugonj upazila of Barisal district in Bangladesh. The chemical constituents of water samples were determined to find out their suitability for irrigation, drinking and Livestock consumption. As per pH all water samples were slightly acidic to slightly alkaline and were found suitable for irrigation, drinking and aquaculture, except 07 samples of ground water which were graded unsuitable for drinking. EC (Electrical conductivity) of all the samples were not problematic for irrigation and all samples were “Medium salinity” group (C2). TDS (Total dissolved solids) of all ground water samples were graded as “fresh” water in quality. Ca and Mg concentration were suitable for drinking. All samples were “excellent” in respect of B concentration. The P concentration in groundwater sources of Babugonj upazila might not be harmful for multipurpose use. No samples of groundwater water contained any arsenic. The Cu concentration was within safe limit for drinking. No detectible amounts of carbonate were present in the collected water samples. The Cl concentrations of all the samples were found to be suitable for drinking but unsuitable for Livestock consumption. SAR (Sodium Adsorption Ratio) of all the samples were as low sodium water (SAR< 10) i.e. S1 category. Based on PAR (Potassium Adsorption Ratio) values the water samples would not be harmful for agricultural corps. Eight samples of groundwater were unsuitable for irrigation in respect of RSC (Residual Sodium Carbonate). In respect of SSP (Soluble Sodium Percentage) 02 samples were “Excellent” and the rest were “good” classes for irrigation. In case of Hardness 03 samples were “Hard” 11 as “Medium Hard” and 01 “Soft” class for irrigation and 03 samples were unsuitable for livestock consumption. Except Cl all the chemical constituents were within the suitable range for livestock consumption.
