Groundwater environmental forensic investigation combining multivariate statistical techniques and screening analyses

Multivariate Statistical Analyses and Applications

I. Introduction: Multivariate Statistical Analyses comprise a number of statistical methods/tools that may be applied to several fields of empirical investigations. Most of these methods have three characteristics in common: (i) they presume availability of data set, say Z(nxk) (in n observations and k variables; k ≥ 2, n>k), collected from the field (observationally or experimentally); (ii) th...

Assessment of spatial changes of stream erosion under environmental factors in Kojoor Firoozkolay region using multivariate statistical techniques

Application of Multivariate Statistical Techniques in the Assessment of Groundwater Quality in Chrompet Industrial Area, Chennai

Multivariate statistical techniques such as factor analysis (FA) and cluster analysis (CA) were applied for the evaluation of spatial variations and the interpretation of a large complex water quality data set of Chrompet in Chennai, Tamil Nadu. 11 parameters of water samples collected from 16 different sampling stations of city was determined. Factor analysis indicates three factors in pre mon...

Investigation of Ground Waters Quality Using Multivariate Statistical Techniques (Case Study: Maragheh-Bonab Plain, East Azerbaijan Province)

Investigation and analysis of groundwater quality to monitor contamination and identify the most important pollutants and pollution points is one of the research fields. The objective of this research was to plan to improve groundwater quality on various spatial and temporal scales. Groundwater information of Maragheh-Bonab plain was collected from 26 wells in 10 years (2001-2011) with 454 samp...

a multivariate statistical analysis of groundwater chemistry data

q-mode hierarchical cluster (hca) and principal component analysis (pca) were simultaneously applied to groundwater hydrochemical data from the three times in 2004: june, september, and december, along the ain azel aquifer, algeria, to extract principal factors corresponding to the different sources of variation in the hydrochemistry, with the objective of defining the main controls on the h...
