Measured parameters were the pH, colour, total dissolved solids (TDS), total suspended solids (TSS), dissolved oxygen (DO), chemical oxygen demand (COD) and biochemical oxygen demand (BOD). Over-exploitation of groundwater is leading to reduction of low flows in the rivers, declining of the groundwater resources, and salt water intrusion in aquifers of the coastal areas. Discriminant analysis confirms the three clusters with nine discriminant variables 1.5%. This study employed the contingent valuation method (CVM) to estimate WTP of the respondents. Thus, efforts are underway to prevent air pollution. The solids-associated ARGs increased during activated sludge stage and were reduced in each subsequent stage. Therefore, the objective of this paper was to assess the efficiency of traditional drinking water treatment plants in the removal of organic and inorganic pollutants (chemical and physical parameters). In particular, M. oleifera as a natural coagulant has historically been used to treat effluents and it continues to be used today. The presence of natural or non-natural pollutants in water resulting from human activity such as the introduction of harmful agricultural and industrial pollutants into rivers that could be the main reason in forming trihalomethane compounds after chlorination step in drinking water production plants. Replacing fossil fuel-fired boilers and heaters with electric or city gas-fired boilers and heaters has reduced the impact of emissions to the environment. include fertilizers, pesticides which may be herbicides and insecticides widely used. It is used in many ways from drinking to industrial and agricultural purposes. Basins in this region yield 1801 to 3050 kg N km−2 year−1 to streams, several times the N yield of basins outside this region. The samples withdrawn during April were extracted by hexane -diethyl ether and analyzed by GC-MS as in figures (3, ... Phosphorus is the second most important nutrient in the eutrophication processes of aquatic ecosystems that occur in urban as well as in agricultural production areas. Death due to water-borne diseases is widespread in Bangladesh, particularly among children. All rights reserved. The coagulant used was Aluminum Sulfate and PAC with several concentration variation of 5% - 40% to the initial TSS concentration of river water. Contaminated water causes some fatal diseases such as cholera, dysentery, diarrhea, tuberculosis, icterus, etc. This review focuses on the main source of water pollution, health effects of water pollution and methods used to treat polluted water. Rapid urbanization is one of the leading contributors to water pollution in Dhaka and could prevent the country from achieving sustainable development. The current study shows the strong potentials of plant extracts as a low-cost technology in purifying water in southern Ethiopia. The traditional drinking water treatment plant considers unstable plant for the removal of organic compounds in the winter and spring with the possibility of forming chlorinated organic compounds. A laboratory experiment with varying weights (0.5 to 125 g) of dried plant extract was placed in 250 ml of the turbid water samples and left for 4hs of retention time. There was no evidence for positive selection of ARGs during treatment.
