Some important physico-chemical properties of water of major ponds of Comilla Town were studied to evaluate the water quality. Eight water samples were collected during the dry period (March 2005) from eight major ponds of Comilla Town (Ranir dighi, Mandir dighi, Nanuar dighi, Fauzdari dighi, Modina dighi, Dargabari dighi, Darma Sagar and Thakurpara). The result revealed that all the chemical constituents, except a few, are beyond the recommended limit for different uses. Higher value of pH (at Dargabari dighi, Darma Sagar dighi), OM (at Thakurpara dighi, Fauzdari dighi and Modina dighi), NH4+ concentration (at Ranir dighi, Mandir Dighi, Fauzdari dighi, Modina dighi and Dargabari dighi), and lower value of DO (at Fauzdari dighi and Modina dighi) may due to continuous disposal of kitchen wastes, organic wastes, sewage running and fall of twigs as well as extensive used for bathing, washing cloths and utensils etc. All indicate eutrophication and affect community health and hygiene and also create aesthetic problem in the locality.

Considering the well-documented impacts of land-use change on water resources and the rapid land-use conversions occurring throughout Africa, in this study, we conducted a spatiotemporal analysis of surface water quality and its relation with the land use and land cover (LULC) pattern in Mokopane, Limpopo province of South Africa. Various physico-chemical parameters were analyzed for surface water samples collected from five sampling locations from 2016 to 2020. Time-series analysis of key surface water quality parameters was performed to identify the essential hydrological processes governing water quality. The analyzed water quality data were also used to calculate the heavy metal pollution index (HPI), heavy metal evaluation index (HEI) and weighted water quality index (WQI). Also, the spatial trend of water quality is compared with LULC changes from 2015 to 2020. Results revealed that the concentration of most of the physico-chemical parameters in the water samples was beyond the World Health Organization (WHO) adopted permissible limit, except for a few parameters in some locations. Based on the calculated values of HPI and HEI, water quality samples were categorized as low to moderately polluted water bodies, whereas all water samples fell under the poor category (>100) and beyond based on the calculated WQI. Looking precisely at the water quality’s temporal trend, it is found that most of the sampling shows a deteriorating trend from 2016 to 2019. However, the year 2020 shows a slightly improving trend on water quality, which can be justified by lowering human activities during the lockdown period imposed by COVID-19. Land use has a significant relationship with surface water quality, and it was evident that built-up land had a more significant negative impact on water quality than the other land use classes. Both natural processes (rock weathering) and anthropogenic activities (wastewater discharge, industrial activities etc.) were found to be playing a vital role in water quality evolution. This study suggests that continuous assessment and monitoring of the spatial and temporal variability of water quality in Limpopo is important to control pollution and health safety in the future.

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

Background Objective: River Ose has flowing water throughout the year that can serve for irrigation and domestic purposes. This study examined the hydrochemistry, water quality indices and coliform counts of River Ose Water, Nigeria with a view to ascertain its suitability for drinking and irrigation.Materials and Method: For this purpose, 15 water samples were collected along the flowing river channel and subjected to physico-chemical and e-coli determination using standard methods. Water quality index (WQI) and Irrigation parameters (Sodium adsorption ratio (SAR), Percentage sodium (%Na), Residual sodium bicarbonate (RSBC), Kelly’s ratio (KR), Permeability index (PI) and Magnesium absorption ratio (MAR)) were calculated from the chemical data obtained from the analyses.Results: Results of the analyses revealed that pH (9.7 pH of the water samples were of alkaline nature with all the water samples exceeding approved standard for drinking water. Drinking alkaline water may deactivate pepsin but it could lead to gastrointestinal problems and metabolic alkalosis. Electrical conductivity (µS/cm), Total dissolved solids (mg/L) as well as Total hardness of all analyzed water samples fell in the category of fresh water. HCO3- and Cl- were the dominant anions while Na+ and K+ constitute the dominant cations in the water chemistry. The abundance of major ions revealed Na+> K+ >Mg2+>Ca2+ and HCO3->Cl->SO42->NO3- trend. The dominant hydrogeochemical facies was mixed Ca2+-Na+-HCO3- (93%) with few mixed Ca2+-Mg2+-Cl- (7%) while calculated WQI was 89.44. All samples tested positive to e-coli count ranging from 1.71*101 – 8.100*103.Conclusion: The analyzed physico-chemical parameters in all River Ose water samples were well within approved desirable limits except for the pH. However, the water was not potable as all samples tested positive to e-coli counts. In addition, WQI calculation revealed that the water has very poor drinking quality. Sources of ions in the River were predominantly from rainfall and minor weathering from the bedrocks. Irrigation quality parameters (SAR, %Na, RSBC and KR) indicated that River Ose water was good for irrigation. However, applying the water on salt sensitive plants is not advisable as irrigation evaluation employing PI and MAR showed that the water was not suitable for irrigation.

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.

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.

The study was carried out to assess the water quality of the Jamuna river affected by effluents discharged from the nearby Jamuna Fertilizer Company Limited and its temporal change over wet and dry seasons due to change of the physico-chemical parameters. Effluents of the factories and water samples were collected from four different selected stations during the period of June to August 2014 and January to March 2015.The results further revealed that the water samples showed a remarkable variation in physico-chemical parameters during the wet and dry season. In wet season the mean value of temperature, pH, EC, TDS, TSS, DO, BOD, ammonium, nitrite, nitrate and chloride were28.63± 3.79 °C, 8.10± 0.85, 664.41± 599.54µscm-1, 370.91± 111.38 ppm, 74.49± 25.90 ppm, 6.11 ± 1.28 ppm, 75.39 ± 140.86 ppm 296.74± 303.03 ppm, 12.31±21.38 ppm,  15.19±24.49 ppm and 15.23±8.72 ppm, respectively In the dry season the mean value of temperature, pH, EC, TDS, TSS, DO, BOD, ammonium, nitrite, nitrate and chloride were31.69 ±3.18°C, 8.44± 0.66, 786.25±551.18µscm1, 338.37± 94.70 ppm, 72.08± 58.83 ppm, 5.45 ± 0.95 ppm, 86.93 ± 159.82 ppm, 347.91± 291.60 ppm, 13.68±23.1 ppm, 18.34± 24.92 ppm and 18.3±9.32 ppm, respectively. The comparative study showed that most of the effluent and water quality parameters were higher in dry season than those of the wet season because in dry season less quantity of water remains in the river and in wet season more water remains in river that has great dilution capacity. For existence and conservation of aquatic resources, it is essential to investigate the water quality and surrounding environment of the river.Progressive Agriculture 26 (2): 136-146, 2015
