Arsenic Contamination in Groundwater: a Statistical Modeling
High arsenic in natural groundwater in most of the tubewells of the PurbasthaliBlock 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 t...
متن کاملGroundwater Dynamics and Arsenic Contamination in Bangladesh
Although arsenic contaminated groundwater in Bangladesh is a serious health issue, little is known about the complex transient patterns of groundwater flow that flush solutes from aquifers and carry solutes into the subsurface. Hydrologic modeling results for our field site in the Munshiganj district indicate that groundwater flow is vigorous, flushing the aquifer over time-scales of decades to...
متن کاملArsenic contamination of groundwater: a Bangladesh survey
A series of surveys has been conducted in two rural communities of northeastern Bangladesh where a nationwide contamination of groundwater by geologically originated arsenic has been reported. The arsenic concentrations of the tubewell water (twAs), which has been used for drinking and cooking, varied considerably within the small geographical area, as did the urinary arsenic concentrations (uA...
متن کاملMechanism and source of arsenic contamination in groundwater in Bangladesh
Naturally occurring contamination of arsenic is of great concern in many Southeast Asian countries especially in Bangladesh. Because of the lack of understanding for the mechanism of As contamination, we have developed two studies through field surveys and laboratory experiments. First topic is focused on the underlying mechanisms controlling large spatial variation of As-contaminated groundwat...
متن کاملStatus and Mitigation of Arsenic Contamination in Groundwater in India
High arsenic concentrations in groundwater in different states of India have become a major cause of concern in recent years. The groundwater in the past was considered to be safe for drinking purposes, but now it is recognized that many shallow tube wells contain arsenic at concentrations higher than the safe limit set for drinking purpose by WHO (1993). It is becoming an emerging issue in the...
