“…Both results had shown that the tests were above WHO standards before the treatment plants. The fecal coliform & E.coli tests after water treatment plant was with the range of acceptable standards.Similar studies on E. coli & total coliform were 1-16 CFU/ml & 3-48 CFU/ml in Malaysian river water respectively(24), which were lower than Asella municipality water supply findings.The ammonia concentration throughout the study sites was above WHO recommends to occur until 0.2mg/L (3) for surface water from site 2 to site 5. The finding of ammonia availability was an indication of water pollution by bacteria, sewage & animal waste.…”

Background Drinking water quality is the main concern because in developing countries like Ethiopia, where contaminated water was one of the main vehicles for the transmission of water borne diseases. Therefore, the objective of this research was to assess the physicochemical & bacteriological water quality in Asella town, Ethiopia. Methods A cross-sectional study was carried out from November, 2015 to April, 2016 G.C. 8 liter composite water samples in plastic bottles packed cold chain had been taken by the investigator from eight different sites with two round totally 192 parameters were analyzed. A standard instrument like AAS for heavy metal analysis was using APAH procedures. Statistical analysis was done by the use of software for data entry Epi info 7 & Minitab 19.2. Results The first round of laboratory had showed that mean± SD TH 59.5± 7.4 mg/L, COD 30± 25.8mg/L, calcium 15± 4.3 mg/L, magnesium 5.3± 0.9 mg/L, BOD5 3± 2.6 mg/L and Nitrate 1.5± 0.1mg/L. The result of microbial analysis was 180CFU/100ml for TF & FC, 40CFU/100ml was E.coli detected in the first study site. The second round physical analysis had showed that municipality water was colourles, odourles & tasteless. But the Mean ± SD turbidity was 32.6± 63.4 mg/L. The mean± SD pH 4.5±0.8,EC 101.8±23.1,TH 24± 2.5 mg/L, calcium 6.9± 0.8 mg/L, magnesium 1. ± 0.6 mg/L, Fluoride 0.4± 0.2mg/L, aluminum 0.3± 0.2 mg/L, DO 4.6± 1.2 mg/L, nitrate 3.3± 2.5 mg/L, nitrite 0.9± 2/5 mg/L, zinc 0.3± 0.4 mg/L, CO32- 7. ± 6 mg/l, chloride 6± 1.3 mg/L, alkalinity 6± 4.9 mg/L, total solid 96± 50.3 mg/L, TDS 62± 14.8 mg/L, sodium 3.9± 2.4 mg/L, potassium 1.7± 0.1 mg/L, iron 0. ± 1mg/L and ammonia 0.9± 0.3 mg/L. There was strong pair wise statistical correlation among water quality parameters with p value < 0.05 Conclusions The water quality analysis was below the limit of WHO standard, but some chemical, turbidity & microbes need a critical attention. So, efficient water treatment must be monitored by the municipality & homemade water treatment by urban community

“…TSS are solid in a water body which includes a wide variety of materials, such as silt, decaying plants, animal matters, and other solid wastes [26]. Figure 2 shows the reduction rate of TSS using 50 g of C. asiatica, I. aquatica, S. molesta, P. stratiotes, and E. crassipes plotted against the days of treatment.…”

The lack of clean water sources, due to the presence of pollutants in water, is a major issue in many countries, including Malaysia. To overcome this problem, various methods have been introduced, including phytoremediation treatment. Therefore, this phytoremediation study examined the ability of five aquatic plants—Centella asiatica, Ipomoea aquatica, Salvinia molesta, Eichhornia crassipes, and Pistia stratiotes—to remove three pollutants—total suspended solids (TSS), ammoniacal nitrogen (NH3-N), and phosphate—from aquaculture wastewater. Using wastewater samples, each containing 50 g of one of the plants, the pollutant levels were measured every two days for 14 days. The results showed a drastic decline in the concentration of pollutants, where C. asiatica was able to remove 98% of NH3-N, 90% of TSS, and 64% of phosphate, while I. aquatica showed the potential to eliminate up to 73% of TSS and NH3-N, and 50% of phosphate. E. crassipes drastically removed 98% of phosphate, 96% of TSS, and 74% of NH3-N, while P. stratiotes was able to eliminate 98% of TSS, 78% of NH3-N, and 89% of phosphate. S. molesta was efficient in removing 89.3% of TSS and 88.6% of phosphate, but only removed 63.9% of NH3-N.

“…The variation in the WQI value is affected by anthropogenic factors. Example River areas and areas around agricultural land around cities get more polluted than those that are not [38,39]. Spatial destruction proves a parallel result as Class III of WQI with a few variations to the river plan change in water quality is higher compare others.…”

a b s t r a c tRiver plan change is one of the river geomorphology change process. This study focuses on the processes of the river plan change using geographic information system (GIS), remote sensing, and water quality analysis using water quality index (WQI) parameters. Multiple linear regression (MLR) method was used to observe the relationship between river plan change and WQI. Spatial model method was applied along the mainstream of Terengganu River Basin, using GIS to further justify the impact of river plan change on water quality status. The results obtained shows that the Terengganu River Basin has been going through certain river plan changes due to increase and decrease of the river plan criteria. Based on WQI analysis, the classification of water quality is under class III. Based on MLR, there are strong relationships between dissolved oxygen and river plan change which has value of R 2 0.995, total suspended solids (TSS) with R 2 0.764, and WQI with R 2 0.928 during wet season, whereas during dry season, TSS and WQI showed the strong linear relationship with R 2 of 0.997 and 0.985, respectively. This study will appropriately act as an aid of the local enforcement to determine the problems of the river management.
