TL;DR: In this paper, the major hydro-geochemical process and impacts of anthropogenic activities can be deciphered using multivariate statistical analysis, conventional graphical plots and saturation indices, which is the most important source of drinking waters supply in the National Capital Territory (NCT) of, New Delhi, India.

TL;DR: The correlation between various physiochemical variables and trace metals suggested significant role of fine grained particles (clay) in trace metals distribution whereas owing to low organic carbon content in the region the organic complexation may not be playing significant role in trace metal distribution in the Sundarban mangroves.

TL;DR: Indian part have more polluted sites than Bangladesh side of Sundarban, which is confirmed by enrichment factor, I-geo and normalization values in both the sides.

TL;DR: In this article, the chemical quality of groundwater of Gaya region has been studied in detail in order to delineate the potable groundwater zones, and principal component analysis was utilized to reflect those chemical data with the greatest correlation and seven major principal components representing >80 % of cumulative variance were able to interpret the most information contained in the data.

TL;DR: In this paper, the distribution of trace metals in the world's largest mangrove ecosystem, Sundarban, in India and Bangladesh, was analyzed using a speciation technique to document the bioavailability and environmental hazards associated with operationally defined chemical forms of trace metal.
