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.

The present study has been carried out on Moghat Reservoir situated at Khandwa District of Madhya Pradesh. In the present study, the water samples were analyzed for various physico-chemical parameters like temperature,transparency, turbidity, TDS,  pH, Free CO2, total hardness, Ca hardness, Mg hardness, DO, BOD and COD on two different sites of the reservoir. During the course of study value of DO fluctuated between 6.04 mg/l to 8.58 mg/l. Value of BOD and COD fluctuated from 0.98 mg/l to 3.51 mg/l and 9.0mg/l to 12.3mg/l respctively. It was found that around all the parameters were more or less similar at both the sampling stations. The water quality was found suitable but it is strongly recommended that regular monitoring of the Moghat reservoir at Khandwa is very important as it is the major source of freshwater. Thus it is apparent that much attention should be paid on further studies of the physico-chemical and biological parameters of the Moghat reservoir

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.

A Poluição da água é qualquer alteração das propriedades físicas, químicas e biológicas que possa causar prejuízo à saúde, bem-estar das populações e, ainda, comprometer a sua utilização para fins agrícolas, industriais, comerciais, recreativos e, especialmente, a existência da fauna aquática. Dessa forma, o objetivo desse trabalho foi mensurar os parâmetros físicos, químicos e biológicos, totalizando 20 variáveis em um período sazonal de 4 coletas (inverno 2011, primavera 2011, verão 2012 e outono 2012) da água superficial da bacia hidrográfica do córrego Moeda, em Três Lagoas/MS, e com isso, enquadrar sua qualidade embasado na resolução do CONAMA 357/2005. A área da bacia, aproximadamente 268,39 Km², encontra-se em forte mudança ocupacional, alterando seu principal uso de pastagem para monocultura de eucalipto, que em 2012, ocupava mais de 52% da área total da bacia. Partindo disso, os resultados ilustraram o enquadramento médio restritivo do uso da água foi na classe 3, que preconiza a limitação de suas águas para “abastecimento doméstico, após tratamento convencional; irrigação de culturas arbóreas e forrageiras; dessedentação animal”. Os parâmetros químicos ferro e alumínio e o parâmetro físico cor, foram os que provocaram maiores implicações na qualidade da água. Assim, recomenda-se que o monitoramento da qualidade seja usado para futuros planejamentos e ações para evitar aumento da contaminação das águas superficiais na bacia do córrego Moeda. Seasonal physical, chemical and biological quality of surface waters of the Moeda stream watershed in Três Lagoas/MS A B S T R A C TWater pollution is any change in the physical, chemical and biological properties that may cause harm to the health and well-being of the populations and also jeopardize their use for agricultural, industrial, commercial and recreational purposes and, in particular, the existence of aquatic fauna. Thus, the objective of this work was to measure the physical, chemical and biological parameters, totaling 20 variables in a seasonal period of 4 collections (winter 2011, spring 2011, summer 2012 and autumn 2012) of the surface water of the watershed of the stream Moeda, in Três Lagoas/MS, and with that, to frame its quality based on the resolution of CONAMA 357/2005. The area of the watershed, approximately 268.39 km², is undergoing a strong occupational change, changing its main pasture use to eucalyptus monoculture, which in 2012 occupied more than 52% of the total area of the watershed. From this, the results illustrated the restrictive average framework of water use was in class 3, which advocates the limitation of its waters to "domestic supply, after conventional treatment; irrigation of tree and forage crops; animal welfare ". The chemical parameters iron and aluminum and the physical parameter color were the ones that caused the greatest implications in water quality. Thus, it is recommended that quality monitoring be used for future planning and actions to avoid increased surface water contamination in the watershed of the stream Moeda.Keywords: Multiparameter, Bathing, Framework, CONAMA.

Abstract The quality of well-dug water for drinking and irrigation purposes must be measured as part of a sustainable groundwater analysis. The study aimed to assess water quality and to evaluate their usefulness for drinking and irrigation, using the Drinking Water Quality Index (DWQI) and Irrigation Water Quality Index (IWQI). To achieve this, standard methods were used for the determination of physicochemical parameters of the water samples, while using models (ESP, SSP, SAR, MAR, KR, TDS, and EC) to ascertain their suitability for drinking and irrigation. According to the findings, the determined Physico-chemical parameters were compared to standard limits and found desirable because they were within the guidelines. Low pH (6.4-7), total dissolved solids (106–130 mg/L), total hardness (42–56 mg/L), calcium (3.5–8.3 mg/L), magnesium (1.13.6 mg/L), nitrate (4.6–16 mg/L), chloride (1.8–3.1), and sulphate (14–15. mg/L) in the well samples were found to be the key cause of the low DWQI and IWQI value at these sites. The results also depicted that all the water samples are of exceptional quality (excellent).

This study was designed to determine tlie occurrence and removal of Cryptosporidium spp. oocysts and Giardia spp. cysts, in municipal waste-water by waste stabilisation ponds in tlie Republic of Kenya. Eleven waste stabilisation pond systems located in towns across Kenya were included. A total of 66 waste-water samples were examined for the presence of oocysts and cysts, comprising 11 raw waste-water and 55 pond effluent samples over a two month period. Cryptosporidium spp. oocysts were detected in 6 and Giardia spp. cysts in 9 of the designated pond systems analysed demonstrating their ubiquitous nature throughout Kenya. Oocyst levels detected in raw waste-water samples ranged from 12.5 - 72.97 oocysts/l and various pond effluents between 2.25 - 50 oocysts/l. Cyst levels detected in raw waste-water samples ranged from 212.5 to 6212.5 cysts/l and in various pond effluents from 3.125 to 230.7 cysts/l. No Cryptosporidium spp. oocysts were detected in the final effluent from any pond systems studied (11/11). Whereas no Giardia spp. cysts were detected in the final effluent from 10 of 11 waste stabilisation pond systems studied, one pond system was found to be consistently discharging cysts in the final effluent at concentrations ranging from 40 to 50 cysts/l. The minimum retention period for the removal of Cryptosporidium spp. oocysts and Giardia spp. cysts was 37.3 days. Laboratory experiments were performed to assess physico-chemical and microbiological parameters to express relationships between pond performance and protozoa removal.

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.
