Abstract Water quality of collapsible, concrete, earthen and natural ponds under different culture systems were assessed using of Photometer and tester. Temporal and spatial replications of samples were done in triplicates. Dissolved oxygen ranged between 4.6 to 6.8 mg/l, carbon dioxide 1.4 - 3.0 mg/l, nitrate 1.6 - 3.2 mg/l, phosphate 0.8 - 2.3 mg/l, calcium hardness 65- 100 mg/l, magnesium hardness 30 - 50 mg/l and total hardness 80 and 165 mg/l. Conductivity ranged between 346 - 472 μS/cm, total dissolved solids 232 - 316 mg/l, transparency 36 - 82 cm, alkalinity 105 - 245 mg/l, pH 6.35 - 8.03 and temperature 29.1 to 35.9 °C. Significant difference (P<0.05) was obtained among the parameters in the ponds showing the effects of the different culture systems on the water quality. Variations in the water quality was due to the presence of plankton and macrophytes found in earthen and natural ponds where semi-intensive and extensive culture were practiced, use of artificial feed in collapsible and concrete ponds where intensive culture was done, effects of respiration, photosynthesis and decomposition, source of water and materials used for the construction of the ponds. Water quality in the ponds under the different culture systems was good.

Changes in season is one of the important drivers responsible for pollutants transported into surface waters. This study examined the seasonal variations in the quality of Imabolo stream water within Ankpa urban, Kogi State, Nigeria. To achieve the aim of the study, water samples were collected at the peak of the two seasons from seven points along the stream reach corresponding to the different land-use activities in the study area in March and June, 2018. In-situ and laboratory analysis of eighteen physico-chemical and two microbiological parameters were carried out according to standard procedures. Descriptive statistics and t-test were employed to analyze the data obtained for both dry and rainy seasons. The results were compared with WHO and NSDWQ standards for drinking water quality for characterization. The analysis revealed that water samples from six points had elevated values of parameters above the recommended limits for human consumption. The observed seasonal variation indicated that wet season values were higher for all the parameters except DO and Ca2+, while t-test showed significant difference (p < 0.05) in the level of temperature, EC, TDS, turbidity, BOD, COD, nitrate, sulphate, iron, calcium, lead, cadmium, alkalinity, total hardness, total coliforms and E. coli betweendry and rainy season. The study advances innovative recommendations to remediate and improve the quality of the stream water in order to meet the water needs of the users.

ABSTRACT The interception process is responsible for the spatial and temporal redistribution of the precipitation that reaches the ground. The contact of the precipitation with the canopy influences on the water quality, increasing the concentration of various nutrients in the throughfall (Tf) and stemflow (Sf). The objective of this study was to assess the influence of the interception process on the precipitation quality in a catchment covered by Mixed Ombrophilous Forest. The precipitation (P) monitoring consisted of two rain gauges installed outside the basin. Six gauges were installed within the basin for Tf monitoring. The Sf monitoring was conducted in nine trees. Water sampled at all points was analyzed for color, conductivity, pH, turbidity, and total dissolved solids. The concentrations of Nitrate (NO3-), Chloride (Cl-), Phosphate (PO43-), Sulfate (SO42-), Acetate (CH3CO2-) and Calcium (Ca2+) ions were measured in five points, i.e., one precipitation, two throughfall and two stemflow. Measured precipitation, throughfall and stemflow during the period were 652.1 mm, 584.5 mm (89,6% P) and 2.6 mm (0,4% P), respectively. Total interception loss was 65 mm, corresponding to 10% of the total precipitation. The highest values of the physicochemical parameters were found in the Sf and the Tf. The pH was lower in the Sf, and it decreases with the diameter at breast height. There was no significant relationship between the physicochemical parameters and the canopy cover fraction. The analysis shows the significant difference in the water quality of the precipitation that reaches the ground after being intercepted.

Aim: This study examined the physicochemical and bacteriological parameters of Odor River in Orumba North, Anambra State. The parameters considered were pH, turbidity, temperature, Dissolved Oxygen (DO), Alkalinity, total hardness, Sulphate ( ), Chloride, Calcium ( ) hardness, Magnesium ( ) hardness, Iron (Fe), Nitrate  (NO3-), Conductivity, Total Dissolved Solids (TDS), Total coliform and Escherichia coli (E. coli).  The objectives of the study were to assess the similarities that exist amongst the physicochemical and bacteriological parameters of Odor River in Orumba North, Anambra State. Also, to test whether water from Odor river is safe for drinking by the people of Orumba North and its environs. Methodology: The Cluster analysis and the one-sample T-test method were used to analyze the data obtained for this study. Results: The findings of the study revealed that the parameters can be grouped in two groups as follows: group A consists of pH, turbidity, temperature, Dissolved Oxygen (DO), Alkalinity, total hardness, Sulphate ( ), Chloride, Calcium ( ) hardness, Magnesium ( ) hardness, Iron (Fe), Nitrate  (NO3-), and Conductivity while group B consists of Total Dissolved Solids (TDS), Total coliform and E.coli. The physicochemical parameters were found to impact significantly on the variation of the water quality at 5% significant level and their measures did not exceed the World Health Organization (WHO) standard. Further findings revealed that the bacteriological parameters such as the Escherichia Coli and Total Coliform do not significantly impact on the water quality variation of the river and their measures do not exceed the WHO standard.   Conclusion: The physicochemical and bacteriological parameters of Odor River were found to be within the WHO Standard. However, the physicochemical parameters were found to impact on the water quality variation of the river while the bacteriological parameters do not impact on the variation of the water quality of the river. The implication of the physicochemical and bacteriological parameters not exceeding the WHO standard indicates no risk for the users of the river. Hence, water from Odor River is safe for human consumption and agricultural purposes.

AbstractAs the surface water in northern India is the main water resource for regional economic and also supply for drinking and irrigation purposes. However, deficiency of water quality leads to serious water pollution in the Pandoh river basin (PRB). Therefore, the main objective of the present study is to evaluate the quality of surface water. With this objective, surface water samples were collected from the PRB of northern India, and analyzed for pH, EC, turbidity, alkalinity, total dissolved solids, and total hardness. Moreover, geographical information system (GIS) tools were used to prepare the geology, drainage pattern, and location maps of the study region. Surface water quality observed from the PRB has an alkaline nature with a moderately hard type. Further studies are encouraged to better understand the water quality in northern India.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.
