Gần đây, ô nhiễm asen trong nước tubewell là của một mối quan tâm ngày càng tăng giữa các các nhà hoạch định chính sách và các nhà nghiên cứu. Nghiên cứu này đã được dành cho việc điều tra các hiện có mức độ ô nhiễm asen trong nước tubewell và cũng như liên kết giữa các đặc điểm khác nhau tubewells của hai vùng lựa chọn của Bangladesh. Các dữ liệu được thu thập từ một cao asen bị ô nhiễm khu vực tại Chuddyagram Upazila trong Comilla huyện và từ mức thấp khu vực bị ô nhiễm asen Modhupur Upazila trong Tangail. | Natural Arsenic in Groundwater Occurrence Remediation and Management -Bundschuh Bhattacharya and Chandrasekharam eds 2005 Taylor Francis Group London ISBN 04 1536 700 X Arsenic contamination in drinking water of tube wells in Bangladesh statistical analysis and associated factors M.

This study has been devoted to the investigation of the existing arsenic contamination level in tubewell water and as well as the association among different characteristics of tubewells of two-selected regions of Bangladesh. The data were collected from a highly arsenic contaminated area at Chuddyagram Upazila in Comilla district and from a low arsenic contaminated area at Modhupur Upazila in Tangail district. More than two third of the tubewells of that region are private and of the tubewells have been installed in the last ten years. of the tubewells were found to be used by 11-20 persons regularly. Around of the tubewells were completely unaffected by arsenic. About of the tubewells have been installed above 30 m depth level. Among the tubewells under study were found to be marked as safe. Among the users of the tubewells were found to be under risk of arsenic pollution by tubewell water. Most of the government tubewells are safe whereas 58 of the private tubewells are arsenic free. Multiple linear regression analysis suggested that both the depth and age of installation of tubewells .
