Abstract:
A study was conducted to evaluate the water quality of some groundwater of Saidpur Upazila of
Nilphamari district in Bangladesh for irrigation, drinking and livestock consumption. Water
samples were slightly acidic to slightly alkaline. Electrical conductivity of most samples was
'low salinity' group (C1). TDS (Total dissolved solids) was graded as 'fresh'. The
concentrations of Ca and Mg were suitable for drinking. Fe and Cu were within the safe limit for
drinking. The Cl concentrations were suitable for drinking and livestock consumption. Based on
SAR (sodium adsorption ratio) and RSC (residual sodium carbonate), all waters were low
sodium water (SAR< 10). The SSP (soluble sodium percentage) of 15 samples were 'excellent'
and the rest were 'good' classes for irrigation. In case of hardness, out of 25 samples 14 were
within 'desirable limit' and 10 samples were 'maximum permissible' limit and one was 'hard'
for irrigation and livestock consumption. The permeability index (PI) values ranged between
Class II and Class I. All the samples fell in the precipitation dominant area. Based on study
parameters, the groundwater quality of the study area was suitable for drinking, irrigation, and
livestock consumption. |
