The study examined the water supply situation in Abeokuta, with emphasis on the quality of water distributed by the Ogun State Water Corporation from the treatment plant of the Abeokuta Water Scheme. Water samples were collected from standpipes (taps) across the city randomly selected using the stratified random sampling method and was analysed for physical and chemical parameters: pH, total dissolved solids (TDS), electrical conductivity (EC), total alkalinity, total hardness, calcium, magnesium, potassium, sodium, nitrate, bicarbonate, sulphate and chloride. The result of the physical and chemical parameters was subjected to statistical analyses using the multivariate t-test. The result of the treated water was further compared with the result of the analyses of raw water obtained from the source of water used in the treatment plant.

Communal wastewater treatment plant (CWWTP) has been chosen as one system to treat domestic wastewater due to simple technology, flexible management, and cost-effectiveness. There are 376 CWWTP have been recorded by Environmental Agency of Yogyakarta (DLH DIY) that spread in five regencies. Monitoring results on CWWTP effluent showed that some physical and chemical parameters did not meet the domestic wastewater standard. Therefore, evaluation of removal efficiency in terms physical and chemical parameters are necessary. The samples were collected from nine CWWTP in Banguntapan, Bantul and Gamping sub-districts. The physical and chemicals parameters (pH, TSS, BOD, COD, Ammonia, oil, and grease) of influent and effluent from CWWTP are analyzed based on National Standard of Indonesia (SNI) for domestic wastewater. The results show that BOD (>70%) and TSS (>50%) have better removal effectiveness compare with COD, ammonia, oil, and grease (40%). Overall, CWWTP in Banguntapan subdistrict has better performance compare with CWWTP in Bantul subdistrict.

Water is essential to sustain life, and an adequate, safe and accessible supply must be available to all as improving access to safe drinking water can result in tangible benefits to health. In the present study, eighteen water samples from six different study area, viz., Red Hills, T. Nagar, Saidapet, Ashok Nagar, Alandur and Guindy of metropolitan Chennai were tested for their physicochemical and biological parameters, of which Red Hills served as control area. Results with regard to the physical parameters, showed no variation in the colour of water samples which was clear except for control as it appeared light brown. The odour of samples collected from all six study areas was observed to be constant and agreeable. The water temperature, turbidity, electrical conductivity and total dissolved solids for all six study areas ranged from 28.7 to 29.7°C, 3.7 to 11.7NTU, 723.3 to 1099.7μS/cm, and 396.7 to 805.0mg/L. The values of chemical parameters represented by pH, total hardness, total alkalinity, sulphates and flourides ranged from 7.7 to 8.0, 128.0 to 503.3mg/L, 13.3 to 50.0mg/L, 106.6 to 224.0mg/L, and 0.6 and 1.5mg/L. All the samples were found to be free from coliforms except for the control in the case of biological parameters. Overall results indicate that the physical and chemical parameters were found to be within the permissible limits set by standards and biological contamination was absent in the samples except in control which is a natural reservoir.

<p>The present study was carried out to evaluate physico-chemical parameters of two selected sites of salt pans ecosystem located at Bhavnagar coast, Gujarat for a period of one year December-2005 to August 2006. The analytical data obtained from samples become more informative if supplemented with information concerning the sampling site. Hence, the present work is aimed at the assessment of various physical and chemical parameters of water and sediment samples of salterns at Newport and Nari along Bhavnagar coast, Gujarat. The physico-chemical characteristics include temperature, pH, turbidity, salinity, alkalinity, total hardness, total dissolved solids, chloride, calcium, magnesium, sodium, potassium, sulphate and phosphate. The results of various physico – chemical characteristics indicate that with most of the parameters examined the contents recorded were higher in water samples as compared to sediments and also the values were higher at Newport than at Nari. Notable observation was with total hardness and sulphate, where the contents were higher in sediments and the alkalinity, calcium and magnesium contents were higher at Nari than at Newport. The data were subjected by Karl-Pearson correlation coefficient to examine the corelationship in between and among various physical and chemical parameters using SPSS. 15.0.</p>

This study was undertaken by analyzing data from satellite image (Landsat-8 OLI) and geographical information system (GIS) to find the relationship between water parameters and water indices of spectral images. The main purpose of this research was to develop a model for the physical and chemical parameters of Gharraf stream in Iraq. The water  parameters used in this study included: acidity (PH), Total Dissolved Solids (T.D.S),  Alkalinity(ALK), Electrical Conductivity (E.C), Calcium(Ca), Chloride (CL), Sodium (Na), Sulfate (SO4), Potassium (k), Total suspended solid (T.S.S), Total Hardness (TH).Where the samples were taken to seventeen stations with two seasons and at the same time took a satellite image on 4/FEB, 11 / MAY.GIS techniques were used in the beginning to project the coordinates of seventeen stations along the stream in Landsat-8 satellite image for extract data. Then, these data are treated in SPSS software for purpose finding correlation and regression equations. Positive strong correlations between the reflectance of the satellite image and the water parameters in 4/FEB and 11/ MAY with five stations, helped to build six regression models. These models could be used to predict these six water parameters (PH, E.c, CL, SO4, Na and K) at any point along the stream in Iraq from the satellite image directly.
