Hydrogeochemical assessment and appraisal of groundwater quality in Saltora Block, Bankura District, West Bengal, India

AbstractThe present work aimed to evaluate the overall hydro-geological status of Indpur block, Bankura district, West Bengal, India. Despite of having adequate annual precipitation, south-western districts of the state of West Bengal, India, are considered to be a significantly water-stressed area of the state. This is because of unfavorable geological setting near to subsurface occurrence of impervious lithology and inundated nature of surface drainage pattern. The study was carried out both in pre- and post-monsoon seasons of 2019 to obtain an updated current status on concentration and spatiotemporal fluctuations of controlling ions of the subsurface water. Estimation of major physicochemical parameters and specific qualitative chemical characterization of groundwater were rated through field and laboratory studies. Water samples were collected from twenty-two equidistantly scattered tube wells in the block. Seasonal variations of water table elevation heads and subsurface shift of predominant recharge zones of the block were also demarked. Drinking, domestic and irrigation suitability of the block water were measured by the estimation of parameters such as Sodium Adsorption Ratio (SAR), Magnesium Adsorption Ratio (MAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Permeability Index (PI), Total Hardness (TH) and Kelly’s ratio (KR) and piper trilinear plots. Sustainable non-availability of groundwater seems to be the major problem of the studied area, which intern resulted in overexploitation, mostly for cultivation practices causing considerable depletion of its suitability as drinking and irrigation. Further, results show that suitability of the water both for domestic and irrigation of the studied area may be termed as ‘good’ to ‘moderate’ with a few exceptions on a local scale. Judging by every parameter, it can be stated that groundwater of Indpur block is not much suitable for drinking purposes.

Butterfly diversity was observed in different habitats of Bankura District, West Bengal, India. This district is located at the junction of Chotanagpur plateau and Gangetic plain; it contains a variety of transitional habitats. We found 117 butterfly species from our covered survey area. The highest species recorded in the present study belonged to family Lycaenidae (30.76%) and Nymphalidae (29.91%) followed by Hesperiidae (16.23%), Pieridae (13.67%), Papilionidae (8.54%), and Riodinidae (0.85%), respectively. Based on sighting we found that 12.82% of all the butterflies recorded were abundant in nature while 21.36% were very common, 41.88% were frequent, and 23.93% were rare. Cluster analysis and other diversity indices gives us an overall idea about environmental health. The pattern of diversity change from plain to plateau gradient gives important insight about ecological edge effect. High species number in relation with low individual numbers were found in forest habitat. This preliminary study showed that heterogeneous habitats could harbour many butterflies and need proper conservation efforts to sustain it.
