Salinization and arsenic contamination of surface water in southwest Bangladesh
To identify the causes of salinization and arsenic contamination of surface water on an embanked island (i.e., polder) in the tidal delta plain of SW Bangladesh we collected and analyzed water samples in the dry (May) and wet (October) seasons in 2012-2013. Samples were collected from rice paddies (wet season), saltwater ponds used for brine shrimp aquaculture (dry season), freshwater ponds and...
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 کاملSources of salinity and arsenic in groundwater in southwest Bangladesh
BACKGROUND High salinity and arsenic (As) concentrations in groundwater are widespread problems in the tidal deltaplain of southwest Bangladesh. To identify the sources of dissolved salts and As, groundwater samples from the regional shallow Holocene aquifer were collected from tubewells during the dry (May) and wet (October) seasons in 2012-2013. Thirteen drill cores were logged and 27 radioca...
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...
