Arsenic Contamination in Groundwater: A Statistical Modeling

Abstract

Abstract:High arsenic in natural groundwater in most of the tubewells of the Purbasthali-Block II area of Burdwan district (W.B, India) has recently been focused as a serious environmental concern. This paper is intending to illustrate the statistical modeling of the arsenic contaminated groundwater to identify the interrelation of that arsenic contain with other participating groundwater parameters so that the arsenic contamination level can easily be predicted by analyzing only such parameters. Multivariate data analysis was done with the collected groundwater samples from the 132 tubewells of this contaminated region shows that three variable parameters are significantly related with the arsenic. Based on these relationships, a multiple linear regression model has been developed that estimated the arsenic contamination by measuring such three predictor parameters of the groundwater variables in the contaminated aquifer. This model could also be a suggestive tool while designing the arsenic removal scheme for any affected groundwater.

Effect of Arsenic and Manganese Exposure on Intellectual Function of Children in Arsenic Stress Area of Purbasthali, Burdwan, West Bengal

“…On the other hand, availability of arsenic in drinking water showed very week negative relationship with Fe in all the studied village water except South Srirampur Cumudani FP School as presented in Tables 8, 9, 10 and 11. Almost similar findings were reported by Roy et al (2013). Regression analysis between overall water arsenic level in polluted area and IQ level of the school children residing in polluted area showed weak relationship which is confirmed from the regression coefficient R 2 = 0.365 (Fig.…”

“…The study area was selected on the basis of the previous literature (Biswas 2010;Mondal et al 2011;Roy et al 2013). In this particular area (Purbasthali Block-II, Burdwan, West Bengal, India), cultivation is the main source of income of its population.…”

“…In West Bengal, the range of arsenic concentration in drinking water is 0.05-3.5 mg/L (Das 2008). High arsenic in natural groundwater in most of the tube wells of the Purbasthali-Block-II area of Burdwan district (W.B, India) has recently been focused as a serious environmental concern (Roy et al 2013). Where as in soil, 2.593 mg/kg was reported (Mondal et al 2015) and in food crops it varied from 0.000 to 1.464 mg/kg of dry weight (Rahaman et al 2013).…”

Modeling of the adsorptive removal of arsenic(III) using plant biomass: a bioremedial approach

“…The proposed indigenous biosorbent AiBP was satisfactorily tested for the removal of arsenic from real CGW sample. Hundred ten natural CGW samples were collected from an arsenic polluted region of Purbasthali Block-II in the district of Burdwan, West Bengal, India (Roy et al 2013b). Out of 110 tubewell water samples, the maximum concentration of inorganic arsenic (total) was 261 lg L -1 as recorded in our earlier study.…”

Isolation and characterization of arsenic-resistant bacteria and possible application in bioremediation

“…Purbasthali block of Burdwan, West Bengal, India is severely affected with arsenic. According to Roy et al [16] , the arsenic concentration in the tube well water of this area is 0.076–0.205 ppm. But no research has been conducted to isolate arsenic resistant bacteria from this particular affected area and also to apply these bacteria in bioremediation of arsenic contaminated ground water till date.…”
