<p class="StandardTextkrperSAR">Water samples were collected from three sites (Ogbakiri, Choba and Iwofe) of the New Calabar River and were evaluated for microbiological and physico-chemical characteristics. Bacterial isolates consisting mainly of gram-negative bacteria (<em>Escherichia coli, Proteus vulgaris, Acinetobacter</em> spp, <em>Pseudomonas aeruginosa</em>, <em>Enterobacter aerogenes, Klebsiella</em> spp., <em>Vibrio</em> sp. and <em>Nocardia asteroides</em>) were isolated from the samples. The highest total coliform counts log<sub>10</sub> 2.9 were encountered in water samples from Iwofe but the lowest counts log<sub>10</sub>1.9 occurred in the water samples from Ogbakiri. Ecological parameters varied among the sites with the highest pH value of 7.87 occurring at Iwofe and lowest of 6.12 at Choba. Maximum salinity level of 15<sup>0</sup>/<sub>00</sub> was observed at Iwofe and lowest at Choba. In contrast, maximum dissolved oxygen of 10.1ppm was observed at Choba and the minimum at Iwofe. The different bacterial profiles are probably attributable to the anthropogenic and industrial activities of the sites.</p>

A study was carried out to analyze the ground water samples from fifty sites within the urban settlements of Khushab city, Pakistan in order to to understand the distribution of contaminants and its impact on public health in the studied area. All the water samples were analysed using physico-chemical parameters : pH, Electric Conductivity (EC), Total Dissolved Solids (TDS), Total Hardness (TH), Ca+ , Mg+, Cl- and NO3-by using standard analytical methods. Salinity hazard was evaluated by using EC values inferred from the water samples. Water samples were classified on the basis of TDS and TH.Arc GIS software was used to plot the spatial distribution of contamination, concluded from the observed physico-chemical parameters throughout the study area. A door to door survey was also conducted to get the feedback from 100 people living in the houses, working in offices and shops to know the issues of water quality along with the level of satisfaction for the present water quality.Results showed that pH value ranging between 6.8 and 8.7, EC between 260 and 10290 S/cm, TDS between 179 and 9410 mg/l, Ca+2 between 1.2 and 11.8 mg/l, Mg+2 between 0.3 and 39.4 mg/l, TH between 6.23 and 216.86 mg/l, Cl- between 0.3 and 344.7 and NO3 between 12 and 62 mg/l. Results showed certain sites indicating poor water quality through deviation from WHO standard values of certain physico-chemical parameters. This showed that ground water at particular sites within the study area was unfit for drinking purpose and its prolonged utilization could cause serious health issues. More than 62% people reported their dissatisfaction regarding water quality and 80% agreed that water quality has drastically declined. Results were also correlated with the data collected from the Tehsil Headquarter Hospital which demonstrated that residents of Khushab city were suffering from the water borne diseases like Hepatitis, Cholera, Gastro, and Kidney stone etc. Almost 40,000 patients from Khushab city and the surrounding villages who suffered from water borne diseases visited the Tehsil Headquarter Hospital in the year 2014. It has been concluded from the study that the ground water of the study area has declined and needs proper and urgent attention from the government and water must be processed through state of the art purification treatment plants, before supplying to people for drinking and domestic purposes.

The concern over exposure to drinking water contaminated and the resultant adverse effect on human health has prompted several studies evaluating the quality of drinking water sources. This study was carried out to determine the bacteriological and Physico-chemical qualities of commercial borehole water within Otuoke community in Bayelsa state Nigeria. Ten (10) water samples were collected from the various locations designated as (A-J). The Physico-chemical parameters were determined by using the photometric technique through the Colour Q photometer and the bacteriological analysis was determined by using aerobic plate method. The Physico-chemical parameters of the water samples analysed were within the acceptable limit of WHO standard of drinking water quality except for Bromine and cyanuric acid which ranged from 1.6±0.1 to 2.7±0.1 and 2±1 to 9±1 respectively. The Result of total bacteria count obtained from the borehole water samples ranged from 1.1 x 105cfu/ml to 6.9 x 105cfu/ml and there was no detected growth for the faecal coliform count of most of the samples except for BHW-I and BHW-J which had 1.3 x 104 to 7.9 x 104 respectively. Bacteria isolated and identified using conventional biochemical test include E. coli (17.9%), Klebsiella spp. (35.7%), Salmonella spp(25.0%), Enterobacter aerogenes (21.4%) The study therefore suggests that all the borehole water tested in Otuoke and environs are considered unsafe for consumption and therefore regular treatment before usage is recommended.

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.

Water quality is an index of health and well being of a society. The pollution of water bodies is one of the areas of major concern to environment. In the present investigation an attempt has been made to evaluate the physical, chemical and microbiological parameters of Jhajjar rivulet of J&K. The study has been carried out by taking water samples at three different sites of the rivulet i.e. site 1, site 2 and site3. During the study, the physico-chemical parameters like pH, temperature, colour, total hardness, BOD, COD, DO, TDS and TSS in the water samples were studied. In microbiological examination, the presence of coliform in the water samples were studied.  It has been observed that there was a pollution load mostly at site 3 and slightly at site 2, it may be due to the release of huge quantities of sewage, effluent and manmade activities at the respective sites but the water from all the sites was found free from microbial contamination. It was concluded that water at site 1 is suitable for drinking as compared to site 2 and site 3 of the rivulet.
