This research aimed at assessing the influence of Municipal Waste on Otamiri River by comparing the levels of the contaminants against the set limit by regulating agencies. Stream samples were collected at five different points along the stream using the conventional WHO (2004) methods. The Physico-chemical of the samples collected were analyzed. The results were compared against the standards of regulating agencies. Spatial variations in Physicochemical parameter variations were observed in the levels of the physicochemical parameters measured across the sampling locations. Maximum levels of pH, water temperature and K+ ions were recorded in sampling Locations (SL) 5 (7.12, 29.00C and 2.73mg/L respectively). Maximum levels of TSS, TDS and Turbidity were recorded in sampling locations 4 and 5 (568.60mg/L, 67mg/L, and 110.24 NTU respectively). Maximum levels of EC, Alkalinity and Acidity were recorded in SL 4, 5 and 1 respectively (154.30mg/L, 37.33mg/L, and 32.44mg/L respectively). Maximum levels of DO, BOD, and Chlorides (5.60 mg/L, 3.53 mg/L, and 120.60 mg/L respectively) were recorded in SL 1 and 2. Maximum levels of Ca+, Mg+ and Na+ ions (64.24 mg/L, 3.60 mg/L, and 5.27 mg/L respectively) were recorded in SL 4 and 5. Maximum levels of Ammonia and Total Hardness were recorded in SL 5 (0.100 and 98.27 respectively). The constant dumping of refuse at the site has increased the concentration of organic and inorganic constituents of the river water, even though some remain within established standards. Water from Otamiri River requires elaborate treatment before it could be suitable for domestic purposes.

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.

Tarahara Fish Farm includes 37 large ponds as a fish super zone. Physicochemical parameters viz., air and water temperature, pH, DO, BOD, CO2, Cl-, TA and TH of these ponds were studied for two years (Nov. 2008 to Oct. 2010). The air temperature had positive and significant correlation with water temperature (r=0.893, P<0.01) but inverse and significant correlation with DO (r = - 0.669 P<0.05) and TH (r = - 0.673, P<0.05). Both air and water temperature showed a decreasing trend during the winter months of November to January and again September to October in both years. Similarly, positive and significant correlation showed by pH with DO (r =0.660, P<0.05) and BOD (r =0.846, P<0.05); by free CO2 with DO (r=0.854, P<0.01), chloride (r=0.648, P<0.05) and TA (r=0.616, P<0.05); by DO with TA (r =0.715, P<0.01) and chloride (r =0.625, P<0.05) and by TH with TA (r= 0.592, P<0.05) but inverse and significant correlation showed by pH with water temperature (r =-0.671, P<0.05); by free CO2 with BOD (r=-0.627, P<0.05) and by DO with BOD (r = -0.810, P <0.01). The water quality parameters were within suitable range for the fish growth and breeding with small fluctuations in different months during the first and second years. Physico-chemical parameters significantly (P<0.01; 0.05) differed between different months. However, no mass mortality of fish was recorded from this site. So, the area selected as fish super zone is fruitful to meet the expected production level of fishes and fish seeds in peripheral areas.

Malwa region of Punjab state, India has become the center of water borne diseases due to excessive use of pesticides, chemical fertilizers, heavy metals, industrial toxins that cause toxicity in water. The main contamination in ground water is by physico-chemical parameters and heavy metals i.e. pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, arsenic and lead. The contamination of ground water with heavy metals causes health hazards to humans and animals. Due to lack of adequate facilities and resources for the management and handling of waste, the ground water contamination has been increased. In the present study, assessment of ground water quality was carried out in the villages of Ferozepur district of Punjab state, India. With main emphasis on analyzing the groundwater parameters of Ferozepur district which are responsible for health hazard to humans and animals. Various groundwater samples were collected randomly from the villages of Ferozepur district and analyzed for pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, heavy metals (arsenic and lead) using standard procedures. The concentrations of calcium, chlorides, fluorides and pH were within the permissible limits, whereas, alkalinity and total hardness were observed beyond permissible limits in most of the water samples. Even among majority of the samples taken, the concentration of arsenic and lead was found within the permissible limits. Results showed that the ground water samples collected from depth ranging from 100 to 360 ft, recorded values within permissible limits for drinking purpose as prescribed by WHO. Further, ANOVA has been applied on analysis results to study the effect of pH on fluoride and chloride, depth on fluoride and chloride and depth on arsenic and lead. Also, to adjudge the overall quality of water in Ferozepur district, the water quality index (WQI) has been calculated on the basis of large number of physico-chemical characteristics of water. The water quality index of ground water in Ferozepur district has been calculated to be 107. The value is close to 100 so the quality of ground water in Ferozepur district can be categorized under 'Good Quality' water.

Groundwater as a source of potable water is becoming more important in Nigeria. Therefore, the need to ascertain the continuing potability of the sources cannot be over emphasised. This study is aimed at assessing the quality of selected groundwater samples from Ilorin metropolis, Nigeria, using the water quality index (WQI) method. Twenty two water samples were collected, 10 samples from boreholes and 12 samples from hand dug wells. All these were analysed for their physico – chemical properties. The parameters used for calculating the water quality index include the following: pH, total hardness, total dissolved solid, calcium, fluoride, iron, potassium, sulphate, nitrate and carbonate. The water quality index for the twenty two samples ranged from 0.66 to 756.02 with an average of 80.77. Two of the samples exceeded 100, which is the upper limit for safe drinking water. The high values of WQI from the sampling locations are observed to be due to higher values of iron and fluoride. This study reveals that the investigated groundwaters are mostly potable and can be consumed without treatment. Nonetheless, the sources identified to be unsafe should be treated before consumption.KEYWORDS: groundwater, water quality index, potability, physico - chemical, parameter

The water quality and concentrations of selected heavy metals (cadmium, lead, and zinc) in Saba River, Osogbo were assessed monthly over a period of six months with a view to providing information on the water quality of the potentially polluted urban river system. Three sampling sites were selected along the Saba River (the upper reach of the river (Station A), mid-point of the river (Station B) and the lower reach of the river where it emptied into River Osun (Station C)). The recorded ambient air and water temperature, pH, alkalinity conductivity, total hardness, BOD and COD, as well as the phosphate and nitrate levels of Saba River, were within the maximum allowable regulatory limits of WHO (2011). The dissolved oxygen level between March and April in all the sampling points were in the limit of putting aquatic life under stress (<5.0 mg/L). Also the alkalinity level in station B between February and June, and in Station C from February till May were however above the maximum allowable desirable range of EPA (2001) and WHO (2011). The concentration of zinc, which ranged from 717 to 1,000 µg/L, was the highest amongst the selected metals assayed in the water. However, the mean concentration of lead in the water samples collected from Stations B and C (26 µg/L and 24 µg/L, respectively) was found to be above recommended regulatory acceptable limits of 20 µg/L of WHO (2011) and FEPA (2007). The study concluded that the physico-chemical indices of the water quality indicated that the river was mildly polluted.

Binwa is a perennial hill stream of the Western Himalayan region of Himachal Pradesh. During the present investigation, four observation sites based on altitudinal differences were selected, i.e., Kharli(S1), Baijnath (S2), near Chobin (S3), and Triveni (S4) and water samples were analyzed for physico-chemical and biological parameters for one year (Mar.2011-Feb.2012). Water temperature, water current, dissolved oxygen, turbidity, T.D.S., electric conductivity, total Hardness, phosphate, and nitrate had played an essential role in determining the variations in planktonic and macroinvertebrate fauna of the stream.Species diversity indices such as Simpson, Shannon and Wiener, and Margalef’s diversity index of macroinvertebrates were worked out for all the observation sites. Based on the comparison of physico-chemical parameters of water samples with different standards prescribed for drinking water, water quality index for four stations calculated. Similarly, EPT taxa (Ephemeroptera, Plecoptera, Trichoptera) measured, and EPT index computed. The water quality of the stream deteriorates downstream from head to mouth due to different types of anthropogenic interferences. The findings revealed that stream has no pollution at S1, while it is oligotrophic from S2 to S3 and meso-oligotrophic at S4.

Comparison Of The Results

In-depth analyses of physicochemical parameters and dissolved nutrients in Lake Naivasha was done during the dry (June 2014) and wet seasons (May and April 2016). A comparison of the results was made between the two seasons. Dissolved oxygen in Lake Naivasha was higher in comparison to other fresh water lakes within Kenya while relative stability was noted in the other physico-chemical parameters (pH, temperature and conductivity). Results also show that Lake Naivasha is phosphorus limited aquatic system with measurements ranging between 0.07 – 0.23 mg/l in March and 0.09 – 0.83 mg/l in April 2016. Nitrates ranged between 0.10 mg/l – 0.30 mg/l in March 2016 while in April no Nitrates were detected in the water samples. Sources of nutrient loading into the lake should be investigated and proper measure to be taken for sustainability of Lake Naivasha.

The Impact

The present study was carried out to determine the impact of the leachate contamination on water quality of Kolpu Khola nearby Sisdol landfill site. Water samples were collected from six different sites of Kolpu Khola from upstream to downstream. The samples were collected in clean plastic bottles from a leachate collection from December, 2007 to August, 2008 and analyzed for the determination of physical parameters (pH, conductivity, temperature) and chemical parameters (dissolved oxygen, alkalinity, chloride, calcium hardness, total hardness, BOD5, PO4-P, NO3-N, NH4-N) using a standard method. It was found that leachate was severely polluted with most of the physicochemical parameters being higher than the generic standard for industrial effluent discharged into inland surface water. The variation of BOD and COD showed that the chemistry of the leachate in the landfill was undergoing rapid change. The surface water of Kolpu Khola was not polluted from chloride point of view and the spatial variation of chloride content was significant at 0.01 significance level. The river water at all the sites under study had PO4-P above natural range i.e. 0.005 to 0.020 mg/l and was not suitable for livestock drinking and for aquatic animals with reference to most of the physicochemical parameters studied.DOI: http://dx.doi.org/10.3126/njst.v15i1.12026Nepal Journal of Science and TechnologyVol. 15, No.1 (2014) 107-114
