STUDY ON THE ARSENIC CONTAMINATION AND MITIGATION IN COMILLA DISTRICT (Pages : 138 - 143)

The presence of arsenic in ground water pulled through tube wells has become a serious health hazard for the rural people. Massive public health engineering service programs have been launched to provide safe drinking water for the people in the country through GO/NGO agencies. The technologies used by different agencies such as rice husk method, one and two bucket unit method, arsenic removal unit and indigenous others to remove arsenic from groundwater are evaluated in view of bio-technical concepts. The salient results showed that 84% instruments used for the purpose of removing arsenic were not appropriate and standardized. But the performances of all these technologies were varied from 23 to 76% as for its effectiveness as measured by humanic symptoms. The technical acceptability of the mechanisms was also found to vary from 49 to 83% in different areas of Comilla district. The wide gap of performance and effectives found mostly due to errors with equipments and operations. It is recommended that the improvement covering selection and appropriate instrumentation of the process can reduce arsenic contamination and enhance removal or mitigation of the hazards by up to 30% in the study area which needs intensive training on the technically acceptable equipment and processes.Download
