An application of Water Quality Index (WQI) and multivariate statistics to evaluate the water quality around Maddhapara Granite Mining Industrial Area, Dinajpur, Bangladesh

Pure water is an absolutely necessary component of the earth not only for life but also for sustainable socio-economic development of today’s civilization. The aim of this study was to analysis the quality of water resources and to investigate the influences of mining activities on water quality around the Maddhapara Granite Mining area, Dinajpur, Bangladesh. 31 samples from surface and groundwater were collected from this selected area to assess their hydrochemistry, suitability, and their possible sources of contamination. Consequently, in the case of physico-chemical analysis, the 24 parameters such as PH, Electrical Conductivity, TDS, TH, Ca2+, Mg2+, K+, Cd2+, Cr3+, Cl−, $${\text{SO}}_{4}^{{2{ - }}}$$ , $${\text{PO}}_{4}^{3 - }$$ , $${\text{NH}}_{4}^{ + }$$ , $${\text{NO}}_{3}^{{ - }}$$ , $${\text{HCO}}_{3}^{{ - }}$$…
