“…For further evaluation of extent of metal contamination in the study area and source identification, principal component analysis was used following standard procedure reported in literature (Dragović et al 2008;Yu et al 2008;Franco-Uría et al 2009;Alexakis 2011;Zheng et al 2013). The loadings of measured heavy metal concentrations in the coordinate system of three principal components (PC) were obtained by analysing the correlation matrix.…”

“…The loadings of measured heavy metal concentrations in the coordinate system of three principal components (PC) were obtained by analysing the correlation matrix. For the purposes of determining inter-element relationships, factor loadings between 0.50 and 0.75 were defined as ''moderate'', loadings [0.75 were defined as ''high'', and loading \0.5 were defined as ''low'' (Stamatis et al 2011). In detail, principal component 1(PC1) has the high positive loadings of Cd and Pb ([ ?0.86) and accounts for 58.17 % of variance (Table 4) and is the most important component.…”

The spatial distribution and hazard assessment of heavy metals in the soils of surrounding agricultural fields affected by mine drainage of Ledo coal mining area of Tinsukia district, Assam, India, were investigated using statistics, geostatistics and geographic information system techniques. The amounts of Cr, Cd, Ni and Pb were determined from 83 soil samples collected within the contaminated area. The maps based on ordinary kriging showed that high concentrations of heavy metals were located in the low-lying paddy field and near coal mining site. Indicator kriged probability maps were prepared based on the concentrations to exceed permissible limit (MPL). It was seen that more than 95 % of the studied area has a higher than 50 % probability to exceed the MPL value of Pb and Ni. Multivariate statistical analyses and principal component analysis suggest that Cd and Pb are derived from anthropogenic sources, particularly coal mining activities, whereas Ni and Cr are derived from lithogenic and/or anthropogenic sources.

“…The area of this aquifer is about 150 km 2 and it is located at the eastern part of the river basin. Very recently, Stamatis et al (2011) studied the hydrogeology and hydrochemistry of Oropos-Kalamos basin, which includes the southeastern part of Asopos river aquifer, as well as other aquifers further to the south.…”

“…On the other hand, Stamatis et al (2011) consider increased concentrations of total Cr and Cr(VI) a combination of both natural (ultrabasic rock masses and ultrabasic fragments within Neogene-Quaternary deposits) and anthropogenic sources. More specifically they argue that in the wider region there are Cr-bearing ultrabasic rocks contributing to the Cr(III) loads in alluvial deposits; Cr(III) under favorable conditions (e.g.…”

The Lost Value of Groundwater: The Case of Asopos River Basin in Central Greece

Due to the unique nature of the environmental damage, mainly by Cr(VI), the pollution of the Asopos river basin aquifer in Greece has been recently characterized as an 'environmental crisis'. This paper presents the results of the first attempt in Greece to value the environmental damage to groundwater and to estimate its total economic value using environmental economics. Towards this direction a Contingent Valuation study was conducted, covering the settlements mostly affected in the area. The results indicate that local households are willing to pay an extra monthly charge in voluntary basis for ten years, in order to restore the aquifer under investigation. Different household profiles show different willingness to pay, depending on attitudes against the environmental damage, population age and place of residence. The elicited estimates seem to reflect mostly non-use values and, although smaller than actual private and public expenses for the replacement of the lost public good, the findings are promising and may serve as a spark for future research.

“…It also provides a better understanding of possible changes in groundwater quality. Worldwide several researchers have discussed the groundwater quality-related problems (Stamatis et al 2011;Li et al 2012;Massoud 2012;Chen and Feng 2013;Moosavirad et al 2013). In India too, numerous studies have been carried out to assess the suitability of groundwater quality for drinking and irrigation uses (Gowd 2005;Rao 2006;Brindha and Elango 2011;Dar et al 2011;Ramesh and Elango 2012;Sharma et al 2012;Vetrimurugan et al 2013).…”

Suitability of groundwater for domestic and irrigation purposes as well as its hydrochemical characteristics was estimated in a part of Nalgonda district, Telangana state in southern India. Water samples were collected from 45 wells once every 2 months from March 2008 to January 2010. EC and pH were measured in situ while concentrations of calcium, magnesium, sodium, potassium, sulphate and chloride in groundwater were analysed using ion chromatograph. Carbonate and bicarbonate concentration were determined by acid base titration. General order of dominance of cations in the groundwater of this study area is Na ? [ Ca 2? [ Mg 2? [ K ? while that for anions is HCO 3 -[ Cl -[ SO 4 -2 . Ca-HCO 3 , Na-Cl, mixed Ca-Na-HCO 3 and mixed Ca-Mg-Cl types of groundwater were dominant in this area. Groundwater is generally fresh with medium to high salinity and low alkalinity. Chloride and bicarbonate concentrations were present within the permissible limits for drinking whereas, some samples exceed the permissible limits of the Bureau of Indian Standards for pH, TDS, TH, sodium, calcium, magnesium and sulphate. Potassium exceeded the maximum permissible limits for drinking proposed by World Health Organisation. Sodium adsorption ratio, sodium percentage, residual sodium carbonate and permeability index indicates that the groundwater quality was suitable for irrigation in most parts of the study area.
