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

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

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.

Assessment on the level of pollution of Turag river water was performed by measuring various physico-chemical parameters. Water samples were collected five times in a year both dry and rainy season at five different locations: Bishwa Ijtema field, Tongi Bridge, Kachare ghate, River side of Dhaka Dying and Effluent of Dhaka Dying. Most of the measured parameters exceeded the permissible limit of standard level. Values for different parameters at different points were recorded such as Temperature (T): 23.9 to 31.2°C, pH: 7.2 to 10.1, Salinity: 64 to 933 ppm, Total dissolved solid (TDS): 90 to 1244 ppm, Electrical Conductivity (EC): 135 to 1856 µs/cm, Dissolve oxygen (DO): 0.5 to 3.6 mg/L and Chemical oxygen demand (COD): 220 to 1170 mg/L. The concentration (ppm) of heavy metals were also observed such as Chromium (Cr) 0.0339 to 0.6334, Cadmium (Cd) 0.0068 to 0.0170, Nickel (Ni) 0.1282 to 0.6207, Cooper (Cu) 0.0148 to 0.1703 and Zink (Zn) 0.0366 to 0.1890 at dry season. The values of different parameters determined are above the safe limits recommended by DoE, EQS and WHO. Therefore, it can be concluded that water relieved from selected locations were not suitable for human consumption during the period of experiments.Bangladesh J. Sci. Ind. Res. 51(3), 193-202, 2016

The study was concentrated on water quality appraisal in metropolitan drinking water distribution system in Kathmandu during 2011 to 2015 AD. The study covers 24 research areas from surface water sources, treatment plants, processing and water supply networks of public, private and community drinking water suppliers in the main city of Kathmandu valley. Water quality was analyzed under six physical, seventeen chemical and two bacteriological parameters. All tests were conducted in accordance with the procedures laid down in the Standard Methods. Total 320 samples collected during two years of periods. The physico-chemical parameters of tested water samples from sources, reservoirs and taps were found to be within the range of National Drinking Water Quality Standard (NDWQS). The turbidity and pH values for most of the tested water samples from sources, reservoirs and taps except for a few source and tap samples were found to be within the NDWQS guideline values. The chemical parameters values of majority of tested source water samples were below the maximum level. The values of iron, manganese, sodium and chloride content of some source samples were found higher than the maximum permissible level recommended by NDWQS and WHO guideline. Bacteriologically, larger proportion of water samples (sources, reservoirs and taps) were found to be unacceptable. The present study disclosed fecal contamination to be the major problem in drinking water from source to the distribution for city water supply systems in selected metropolitan areas. The physico-chemical qualities of water in most cases were within acceptable limit.Journal of Institute of Science and TechnologyVolume 22, Issue 1, July 2017, page: 159-164

This study aimed to evaluate the physicochemical properties of water, to determine the macro-benthic invertebrates of this ecosystem. The money samples of water are taken (November - May) at three stations at different depths, including a very polluted one at downstream of the Wadi. Several physico-chemical parameters were measured (pH, electrical conductivity, turbidity, BOD5 MES, water temperature and salinity). The Bi-monthly sampling of macro invertebrates revealed the existence of 40 taxa, divided into 4 branches (amphibians, molluscs, arthropods, annelids), made up of 2344 identified individuals, and distributed according to the bathymetry, where the majority are Arthropods with 95.38%. The annelids represent 3.71%, collected mainly at the level of the strongly anthropized site C. Therefore, the distribution of the macrobenthic fauna, depends on the physico-chemical parameters, on the geographical position.Maintaining a standard water quality in this aquatic ecosystem requires continuous monitoring of its physicochemical characteristics.
