Physical, chemical, and biological parameters of the Kole (Open type) and Suguna (Closed type) wetlands have been investigated from January 2011 to December 2013. These lakes are locally called as Baur.The work has been carried out for one and half year period from nov 2011- May2013 in different seasons viz. monsoon, post monsoon and premonsoon respectively in order to assess water quality parameters and diversity of biotic communities. The present article attempts to investigate the possible interrelationship among the physicochemical parameters and biotic communities of both the beels. During the investigation, zooplankton diversity was observed high in the wetland. Rotifers were the most dominant group followed by Cladocera, Copepoda, Protozoa and Ostracoda during the investigation. There is a high density of zooplankton in monsoon than compare to other seasons indicate good water quality and less pollution load in both beels. These investigations will be the basic guidelines for the researcher in the field of ecology of beels. The comparison of the ecological parameters of these two lakes is attempted in the present investigation. The study aim to investigate the diversity of biotic communities in relation to physico-chemical parameters of surface water in gangetic plain. Physico-chemical parameters of both the beels revealed well marked fluctuations with maxima and minima values of each parameter during specific months and analysis of biotic communities revealed seasonal variations with an increase during summer and a fall during winter and monsoon seasons.

Physico-chemistry and biological data were investigated  from  October 2010 until April 2011 of Jatiluhur reservoir. A total of six sampling stations were selected for this study. The discharge and hidrological data were obtained from Perum Jasa Tirta II Jatiluhur. The results showed that the hydrological regime in the reservoir Jatiluhur was affected by global phenomenon La Nina events in 2010 and early in 2011. Stream flows were determined during sampling to range from 78  to 482.5 m3/s. The water quality findings were as follows: pH (6.93-8.81), temperature (26.37-30.6°C), dissolved oxygen (0.733-5.2 mg/l), conductivity (2.45-233µmhos/cm), COD (7.36-96.9 mg/l), turbidity (4.063-65.6 NTU), total phosphate (0.002-0.324 mg/l), total nitrogen (0.99-5.96 mg/l), chlorophyl (2.237-43.37 mg/m3), visibility (30-160 cm). The eutrophication was pronounced at Jatiluhur reservoir. Canonical Correspendence Analysis found that some water quality parameters correlated positively with the discharge and the water level.

Tarahara Fish Farm includes 37 large ponds as a fish super zone. Physicochemical parameters viz., air and water temperature, pH, DO, BOD, CO2, Cl-, TA and TH of these ponds were studied for two years (Nov. 2008 to Oct. 2010). The air temperature had positive and significant correlation with water temperature (r=0.893, P<0.01) but inverse and significant correlation with DO (r = - 0.669 P<0.05) and TH (r = - 0.673, P<0.05). Both air and water temperature showed a decreasing trend during the winter months of November to January and again September to October in both years. Similarly, positive and significant correlation showed by pH with DO (r =0.660, P<0.05) and BOD (r =0.846, P<0.05); by free CO2 with DO (r=0.854, P<0.01), chloride (r=0.648, P<0.05) and TA (r=0.616, P<0.05); by DO with TA (r =0.715, P<0.01) and chloride (r =0.625, P<0.05) and by TH with TA (r= 0.592, P<0.05) but inverse and significant correlation showed by pH with water temperature (r =-0.671, P<0.05); by free CO2 with BOD (r=-0.627, P<0.05) and by DO with BOD (r = -0.810, P <0.01). The water quality parameters were within suitable range for the fish growth and breeding with small fluctuations in different months during the first and second years. Physico-chemical parameters significantly (P<0.01; 0.05) differed between different months. However, no mass mortality of fish was recorded from this site. So, the area selected as fish super zone is fruitful to meet the expected production level of fishes and fish seeds in peripheral areas.

The wetlands located at the periphery of Jimma town, southwestern Ethiopia, have critical roles in providing a range of ecological and socio-economic benefits, yet they are subject to increasing anthropogenic disturbances, notably through agriculture, settlement, intensive grazing and brick-making. This study assessed the ecological status of these wetlands, and examined the scale of the human disturbances that local communities might impose on them. Macroinvertebrate communities, water quality parameters, and human disturbance scores were assessed. Except for electrical conductivity and water temperature, no significant difference (P < 0.05) was found in physico-chemical parameters between the sampled sites. Nitrate was the only parameter that correlated with significant influence on species richness of the sampled macroinvertebrates. A total of 10 metrics were used to generate the index of biotic integrity (IBI). This IBI was then tested based on macroinvertebrate data collected. Ways of assessing and evaluating the existing ecological status of the wetlands are discussed in the context of physico-chemical parameters, IBI based on macroinvertebrates and human disturbance scales.

The Impact

Considering Ganga River as one of main Holy River in India, millions of people throng to the river to have a holy dip, Aachman (Mouthful of holy water) and cleanse themselves of sins. Magh Mela is a great festival to take place in bank of Triveni (Sangam) at Allahabad and runs more than one and half month, when millions of pilgrims from different regions in India go there for taking a holy bath in Sangam of Ganga. Thus, the bathing in the river during Magh Mela leads to high pollution of the river in comparison to other days such as normal bathing days. This study focused on the water quality status from some selected physico-chemical parameters of River Ganges and the impact of Magh Mela as well as the variation in the river’s flow rate. Results indicate that the pollution load was alarmingly high and the flow of the Ganga had been very poor. Further, the study found that the water was not fit for bathing during the 2012 Magh Mela.

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

Limnological aspects of the Ramsagar lake, a manmade lake of Dinajpur district was studied from January 2013 to August 2013. In this experiment, five sampling points inside the Ramsagar lake were selected and water quality parameters were analyzed fortnightly. Among different physico-chemical parameters, water temperature, dissolved oxygen, total alkalinity, total hardness, phosphate-phosphorus and concentration of Chlorophyll-a did not differ significantly except the water level and pH. A total of 29 species of plankton were recorded where phytoplankton comprised of 21 species and zooplankton comprised of 8 species. Chlorophyceae was found dominant throughout the study period followed by Bacillariophyceae, Cyanophyceae and Euglenophyceae. The highest plankton cell density was observed in the month of July and lowest plankton density was observed during the month of January. The study revealed that on the basis of physical, chemical, biological and environmental conditions the water of the lake was found to be suitable for survival of aquatic flora and fauna and also suitable for fish culture.J.

The Gomti originates from Gomat Taal (Fulhaar jheel) near Madho Tanda, Pilibhit, India. It extends 960 km through Uttar Pradesh and meets the Ganges near Saidpur, Kaithi, 27 km from Varanasi district. The Earth is facing issues with a large kind of pollutants. Healthy soil, clean water, and air are very much necessary to live properly. In today’s world, Soil, water, and air are not any longer clean and pure however create human health risks. Gomti receives immense quantities of untreated waste, agricultural runoff, brings heaps of pesticides, fertilizer, street washout's transportation oil, asphalt, sediment, and lots of sorts of serious metals from different sources. The study area covers the Gomti River in part of Lucknow city of Uttar Pradesh lies between 80.899893 to 80.968180 N latitude 26.886799 to 26.833321 E longitude. To thoroughly investigate the Physico- Chemical Parameters in the Gomti River of Lucknow city, a total of eight sampling sites were selected between Guaghat upstream and Piparaghat. Samples are collected and analyzed from the proposed locations. The Physico-chemical parameters in the water of river Gomti were assessed to know about the water quality of the river. Parameters like temperature, TSS, TDS, pH, Hardness, Turbidity, Dissolved Oxygen (DO), Nitrate, Chlorine, Alkalinity, Calcium, Magnesium, BOD, COD were determined. After analysis of the parameters in the laboratory, variation of the parameters at a different location is analyzed. We present this variation through the graphs. Variation of many of the parameters is within limit according to the standards limit but some parameters show the excess pollution in the river. Dissolved Oxygen is zero at three sites and other three sites it is below 3 PPM which shows the pollution in water. It could be due to the high discharge of water from the catchment area, industries, and various drains. We also analyzed the correlation between the parameters. It will help to know the variation in any parameters by changing the value of other parameters.
