ABSTRACTThe aim of this study is to analyze the water quality parameters and bacterial diversity and thereby understand the effect of water quality on the microbial population structure in the river. The following parameters: total coliforms, chemical oxygen demand, harness, ammonium, nitrite, nitrate, total Kjeldahl nitrogen, dissolved oxygen, total phosphorus, total dissolved solids, and temperature were analyzing along 17 sampling points in the river. The worst levels of pollution were 510 mg/L chemical oxygen demand, 7 mg/L nitrite, 45 mg/L nitrate, 2 mg/L dissolved oxygen, and 756 mg/L of total dissolved solids. Whole metagenome shotgun sequencing was performed at 4 key points along the river (P1,P7,P10 and P17), the first point had clean water and the other points were polluted, as a result of this pollution, the structure of microbial communities along the river have changed. Proteobacteria and Bacteroidetes were the most representative phyla with a relative abundance of 57 and 43% respectively for P1, 82 and 15% for P7, 69 and 27% for P10 and 87 and 10% for the last point P17. P1 is rich in microorganism such as Limnohabitans a planktonic bacterium very common in freshwater ecosystems. However, in P7, P10 and P17 are rich in opportunistic pathogens such as Acinetobacter Arcobacter and Myroides that endangers the health of around 1.6 million people which live around the area. These results elucidate the influence of the pollution on the microbial community and the likely effects on the health of the people around.

Anthropogenic activities such as industrial effluent, domestic and agricultural waste disposal constitute major sources of pollution in water. The effects of these pollutants on the physico- chemical properties of Lake Kivu, Rwanda were investigated at three locations (Gisenyi, Kibuye and Cyangugu) between February 2005 and December 2006. Water samples used for physico- chemical analysis were collected from 12 stratified points on the lake. Samples collected were analysed and interpreted using appropriate international procedures. The physico -chemical properties measured were temperature, conductivity, pH, transparency, salinity, total alkalinity, dissolved organic matter (DOM), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), nitrate – nitrogen, phosphate – phosphorus and sulphate. Mean water temperature measured (24.7 + 0.58 o C) was highest in Kibuye and lowest (24.5 + 0.31 o C) in Cyan gugu. The lake water was moderately hard with mean total alkalinity values of 88.1 ± 1.63mgL -1 ; 79.7 ± 2.36mgL -1 and 81.0 ± 2.46mg L -1 recorded in Gisenyi, Kibuye and Cyangugu respectively; salty and alkaline with mean pH values of 8.87 ± 0.07 in Gisenyi; 8.86 ± 0.06 in Kibuye and 8.91 ± 0.06 in Cyangugu. Total dissolved solids (TDS) level in the lake was above the 500mg L -1 prescribed by WHO while the mean biochemical oxygen demand (BOD) reading was within the range for unpolluted or moderately polluted lake. Water from the lake showed mineralization with mean conductivity values ranging from 1058 - 1184μS cm -1 in Gisenyi; 1058 - 1147μS cm -1 in Kibuye and 1031 - 1116μS cm -1 in Cyangugu. The mean dissolved oxygen values were below the 5mgl -1 limit recommended by WHO for fresh water fish species. SO 4- -2 and NO 3 – N concentration in the lake water does not constitute any serious health risk to both man and the aquatic organisms it supports. However, there is the need to constantly monitor the lake water to mitigate any build up of the ions to a hazardous level.

Water is very significant in the development of a stable community, but many societies are confronted with the challenges of poor wastes management system with indiscriminate waste disposal and bad land practices, which easily pollute water sources and consequently degrade water quality. This study was to analyze the physicochemical properties of ground water from multiple point sources in Jalingo, Taraba state of Nigeria. Water samples were collected from twenty seven (27) sites from the study area during the raining and dry seasons. The analysis was carried out to determining the physico-chemical properties of the ground water and comparing with the World Health Organization (WHO) standard for drinking water. The physicochemical properties of ground water analyzed include; odor, taste, temperature and electrical conductivity were tested in the field using water meter tester. Whereas pH, total dissolved solids, alkalinity, hardness, salinity, iron, manganese, fluoride, nitrate, nitrite, chloride, sulphate and dissolved oxygen were analyzed in the laboratory using Wagtech potable water testing equipment. The physical properties of water analyzed were temperature, odor, taste, and turbidity. Whereas the chemical properties of water analyzed were pH, electrical conductivity (EC), total dissolved solids (TDS), alkalinity, hardness, salinity, iron (Fe), manganese (Mn), fluoride (F−), nitrate (NO3−), nitrite (NO2−), Chloride (Cl−), sulphate (SO42−), dissolved oxygen (DO).The result shows the range of the mean values of the temperature(26.7–33.1) oC, p H(6.5–8.9), Fe (0.01–0.08 mg/L), NO3−(0.01–38.5 mg/l), NO2−(0.01–0.09 mg/l), Mn (0.01–0.17 mg/l), F(0.01–0.82 mg/l), alkalinity(39-204 mg/l), salinity (42-508 mg/l), SO4(14-93 mg/l), total dissolved solids (6–637) mg/l, turbidity(0.4–10.6 mg/l), hardness(48-187 mg/l), and fecal coliforms(1–4)fcu/100mi, dissolved oxygen(1.1–6.87)mg/l, EC(10.99–1066)ohm/cm, Cl (10-320 mg/l). All except alkalinity and hardness are within the WHO permissible standards of quality drinking water. The highest alkalinity (204 mg/l), hardness (187 mg/l) and low dissolved oxygen (6.87 mg/l) attributed to the high concentration of dissolved salts and basic cations in the water. The methodology applied in the study was effective in analyzing the physicochemical properties of water in the study area. Therefore, it was recommended that there should be frequent water source testing by stakeholder in water resources with the view to treating the water. Policy maker should also enforce the regulation of the use of chemical fertilizers, agro-chemicals and the indiscriminate waste disposal.

Buntung Stream is one of the tributaries of Bedog Stream. The Bedog Stream and its tributaries in Bayem, subdistrict of Kasihan to their upstream are categorized as river of B group. The activity of pig raising which have been carried out by some people in BanyuradenGampingSleman which throw away the wastes in this area likely to have effect on physical, chemical, and biological water qualities, especially coliform bacteria.The objectives of this research were to know the changes on the water quality of Buntung Stream due to pig raising waste disposal in BanyuradenGampingSleman and to give alternative solution to the problem. Observation were conducted on the physico-chemical and also biological water qualities of the stream at four stations: Station I (±800 m upstream of the waste disposal point), Station II (at the waste disposal point), Station III (±500 m downstream of the waste disposal point), and Station IV (±900 m downstream of the waste disposal point, before the encountering of Buntung and Bedog Stream). The samples were collected at the station between 09.00-12.00 a.m repeated 10 times during June-July 2001.Based on the data analyses, it could be drawn some conclusions as follows: the pig raising wastes disposal into Buntung Stream increased water discharge and quantities of coliform group and coliform feces. The waste disposal increased total dissolved solids, ammonia, and phosphate contents but decreased dissolved oxygen and pH of the water, and did not affect the water velocity, temperature, and nitrate content. In addition, BOD5 dissolved     oxygen, and the density of coliform bacteria in Buntung Stream after receiving the pig raising wastes disposal were beyond the B group of the water quality standard in the Special Province of Yogyakarta, whereas the content of total dissolved solids, pH, ammonia, and nitrate were still within the range of the water quality standard.

This study was conducted to determine the physicochemical properties, microbiological quality, level of consumption, and effects of treated water from paid water filtration machines on health of the residents of Bandar Baru Bangi and Kajang, Selangor. The number of water samples taken for this study was 15 from the paid water filtration machines studied. The physicochemical assessment such as determination of pH, turbidity, total dissolved solids, conductivity, and dissolved oxygen was conducted, while the inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the mineral content of the treated water. The microbiological quality was determined using the pour plate method for colony count (22°C incubation for 72 hours and 37°C for 24 hours), while for coliforms and Escherichia coli, the membrane filtration method was utilized. The samples of treated water from the paid water filters were based on triplicate sampling (n = 3). The pH, turbidity, total dissolved solid values, and heavy metal concentration were within the safe level according to the Malaysian National Standard for Drinking Water Quality, Ministry of Health (MOH). The overall range for the pH values of the treated water samples was between 6.50 and 7.15, where this was within the recommended range. The total dissolved solids showed that all the treated water samples were in the range of the recommended standard (27 to 92 mg/L). The range of turbidity values for all the treated water samples was from 1.7 to 6 NTU, and the dissolved oxygen range was from 7.7 to 8.2 mg/L. The colony count results showed that most of the water samples complied with the standards of <4 log cfu/mL at 37°C and <3 log cfu/mL at 22°C of incubation temperatures. However, there was the presence of coliforms in four (4/15) of the treated water samples being at more than 4 cfu/100 mL, while E. coli was absent in all of the treated water samples. The overall results showed that all samples were safe to drink according to the Industrial Guide to Good Hygiene Practice by Automatic Vending Association of Britain (2000) and Food Act (1983) except for the four treated water samples (C, D, H, and I). For that reason, the filtered waters require quality evaluation and management, while the filters need to be replaced according to their designated schedule in order to ascertain that the drinking water is safe to be consumed by the public.

A study was carried out to assess planktonic community with some physico-chemical parameters of the Gorveshwari river in Dinajpur district of Bangladesh. Fortnight water samplings were performed at four sites. Findings revealed that water temperature, water level and transparency were within the optimal ranges- 14.33-31.23°C, 1.38-3.97 m and 43.32- 88.67cm respectively. The values of dissolved oxygen, pH, total alkalinity and total dissolved solids were found to vary 7.16 -9.32 ppm, 6.37-8.93, 28.07- 39.56 ppm and 59.87-133.74 ppm in the four sampling sites respectively. From plankton analysis, 36 genera of plankton were identified of which 27 genera were phytoplankton groups and 9 genera were zooplankton. Among them, Chlorophyceae ranked the first position with highest abundance 3.11±0.12×103cells/L. Euglenophyceae was recorded as the minor group of phytoplankton both in number and density. On the other hand, abundance of Rotifera was found to be higher in number (0.95±0.04×103cells/L), while, Crustacean larvae was noticed as scarcer group throughout the study period. Moreover, from correlation analysis it was observed that the abundance of total phytoplankton and total plankton were negatively correlated with water temperature and transparency where positively correlated with water level, pH, dissolved oxygen, total dissolved solids and total alkalinity. This study concludes that the fish production suitability of Gorveshwari river is within productive range though some anthropogenic activities affecting the aquatic biodiversity were also observed throughout the sampling period.

Limnology of a temporary wetland Ashulia was found highly seasonal. Fluctuations of water depth, water temperature, Secchi depth, pH, conductivity, total dissolved solids, dissolved oxygen and alkalinity were studied in three different stations for one year. Water depth showed a range of 1.5 - 4.2 m and Secchi disc transparency from 0.07 - 2.15 m. Annual ranges in respect of pH, conductivity, total dissolved solids (TDS), dissolved oxygen (DO) and alkalinity of water varied from 6.3 -7.2, 92 - 1028 μS/cm,43.4 - 491.0 mg/l, 4.3 - 28.9 mg/l, and 0.71 - 6.45 meq/l, respectively. The wetland showed a good to moderate water quality during rainy season because in this season visibility of water increased, TDS load, alkalinity and conductivity came down to their lowest. Dissolved oxygen content also showed an acceptable water quality value during rainy season.
