Arsenic Contamination and the Chemical Composition of Groundwater in Bangladesh Peter Ravenscroft

Introduction The following slides were prepared by Peter Ravenscroft using data collected during the “Groundwater Studies for Arsenic Contamination in Bangladesh” project during 1998 and 1999. The project was funded by DFID on behalf of the Bangladesh’s Department of Public Health Engineering (DPHE), and carried out Mott MacDonald Ltd and the British Geological Survey. Anybody downloading these is welcome to use these slides for non-commercial purposes provided that they acknowledge the source of the information. The author accepts no responsibility for interpretations or decisions made on the basis of these slides. It is the responsibility of each individual to verify that the information content of each slide meets their needs. Peter Ravenscroft previously worked in Bangladesh with Mott MacDonald. He is now a Principal Hydrogeologist with Arcadis Geraghty & Miller International Inc. He can be contacted by email at pravenscroft@arcadisgmi.com.

Contents Arsenic concentration in wells <150 m deep Probability of arsenic exceeding threshold values Depth Distribution of Arsenic in Groundwater Comparison of arsenic distribution with that of other parameters

Average Arsenic Concentration The map shows the average (or most probable) arsenic concentration in the upper 150 m of the alluvial aquifer system. The geostatistical surface was interpolated using the ArcView Spatial Analyst® software. The grid was calculated from the logarithms of arsenic concentration with the IDW algorithm using 12 nearest neighbours.

Exceedance of Arsenic Concentration Thresholds The animated maps that follow show the probability of arsenic exceeding various concentration thresholds in wells of any depth. The maps automatically progress through thresholds of 10, 50, 200 and 400 ppb. Click to continue

Depth Distribution of Arsenic in Groundwater

Distribution of various hydrochemical parameters in groundwater compared to the distribution of arsenic The geostatistical surface was interpolated using the ArcView Spatial Analyst® software
