River water is very much important for domestic, agriculture and industrial use in Bangladesh which is in critical condition from long time based on research data. During last 40 years, extreme pollution events occurred in peripheral rivers surrounding Dhaka city and Karnaphuli River in Chittagong city. Present data showed that other urban rivers are also in critical condition especially Korotoa, Teesta, Rupsha, Pashur and Padma. The pollutants flowing with water made a severe pollution in downstream areas of rivers. Metals concentrations in river water was found to be higher in dry season. Dissolve oxygen (DO) was nearly zero in Buriganga River and several points in Turag, Balu, Sitalakhya and Karnaphuli River. NO 3 - , NO 2 - and PO 4 3- pollution occurred in different rivers. Zn, Cu, Fe, Pb, Cd, Ni, Mn, As and Cr concentration was above drinking water standard in most of the river and some metals was even above irrigation standard in water from several rivers. Sediment data showed very much higher metal concentrations in most of the rivers especially peripheral rivers in Dhaka and Karnaphuli, Korotoa, Teesta, Rupsha and Meghna River. Metal concentrations in sediment was above US EPA threshold value in most of the rivers. Metal concentrations in fish and agricultural crops showed that bioaccumulations of metals had occurred. The concentration of metals showed the trend like: water

“…Categorization of the non-salinity and salinity areas is based on the absence and presence of salinity in these areas. In Satkhira district, most of the unions are regarded as high salinity hazard areas adjacent to the tidal river near to the mangrove forest and they are highly vulnerable to climate change, sea-level rise, cyclonic storm and flooding hazards (Rakib et al, 2019).…”

An increase in surface and ground-water salinity due to climate change is reported to have become a great threat to the health of coastal inhabitants in Bangladesh. However, little is known about how much such salinity affects the risk of water-related diseases and how such risk can be mitigated in the field. This research examines the association between water-related diseases and coastal salinity along with sociodemographic and anthropometric factors. We conduct questionnaire surveys with 527 households: 273 subjects from the non-salinity and 254 subjects from the salinity rural coastal areas of Bangladesh. The logistic regression analysis demonstrates that the probability of suffering from water-borne, water-washed and water-related diseases are 8 %, 14 % and 11 % higher in the salinity areas than in the non-salinity areas, respectively. However, it is identified that people who consume rainwater as a drinking source and/or belong to "normal body mass index" have less chances of being affected by water-related diseases even in the salinity areas than those who drink ground/pond water and/or belong to "underweight body mass index." Overall, the results suggest that the long-term reservation of rainwater and addressing communitybased food security & nutrition programs shall be effective countermeasures to reduce the risk of health problems in the coastal population and to sustain their lives even under the threat of land salinity.

“…A semi-structured questionnaire was prepared for field investigation to evaluate the health impact of the people who used these tube-well waters. Total 400 (200 children and 200 adults, among them 50% were male and 50% were female) respondents of the study area were interviewed to determine the health status of people in the study area (Rakib et al, 2019;Ali et al 2020).…”

This article is based on a study aimed to determine physiochemical parameters, fecal coliform, total coliforms, heterotrophic plate count, arsenic, iron and lead of water to evaluate their effects on human health. Analysis was carried out on tube-well water collected from Nalitabari township of Sherpur District in Bangladesh. The dissolved oxygen (DO), total dissolved solids (TDS), salinity and electrical conductivity were in the ranges of 4.30 to 7.30 ppm, 350 to 792 mg/l, 0.2 to 0.5%, and 715 to 1,970 μS/cm. The pH values were slightly lesser or more than permissible value. Due to the vicinity to the latrines, 17 tube-wells’ water was contaminated by fecal coliforms. The highest heterotrophic plate count was 7.5×103 cfu/ml in ward-8 of the town. Eschericia coli and Vibrio cholerae were identified in ratio of 30.56% and 18.06%, respectively, in the tube-well water, resulting into diarrhea among children. About 6.94% of tube-well water was contaminated with arsenic. 3.25% and 4.5% respondents were suffering from skin diseases and headache, respectively. So, an alternative source of drinking water should be arranged for a better public health of present and next generations.
