Water quality and phytoplankton diversity were investigated in Gopeswar temple pond of Assam, India. Altogether 45 species of phytoplankton were recorded representing Chlorophyceae (16), Cyanophyceae (10), Bacillariophyceae (14), Euglenophyceae (3), Chrysophyceae (1) and Dinophyceae (1). Phytoplankton peaks were observed in summer and monsoon periods. Correlations of phytoplankton density with different water quality parameters were evaluated and the water body was found to be moderately polluted. Presence of Microcystis aeruginosa along with Navicula cryptocephala throughout the year also indicated its cultural eutrophication and hence, needs management intervention DOI: http://dx.doi.org/10.3329/bjb.v41i2.13446 Bangladesh J.

Situ Gede is one of the artificial lakes/reservoirs in Tasikmalaya, West Java. The lake has functioned as a source of household water needs, fisheries, and tourism. According to determine the development of water management requires information on the trophic status and water quality. This study aimed to obtain information on the trophic status and water quality of Situ Gede. The research was conducted in Situ Gede, Tasikmalaya, West Java, in 2018. Measurement and analysis of water quality parameters used the SNI and APHA methods, while the measurement of trophic status used the Carlson Trophic State Index (TSI). The relationship between water quality parameters and TSI scores was analyzed using Statistica version 8. Based on the analysis, the trophic status of Situ Gede ranged from 69.06-79.04, with an average of 74.61. This value indicated that Situ Gede's trophic status was on a eutrophic level. The physical and chemical parameters that affect the trophic status of Situ Gede are TP, pH, conductivity, TDS, and temperature. The TP values, conductivity, pH, and temperature at Situ Gede were still categorized as normal. The trophic of Situ Gede can be a source of fish growth. Moreover, in general, Situ Gede waters still have sufficient water quality for fish life. Therefore, Situ Gede has the potential to capture fisheries, recreational fisheries, and aquaculture.Keywords:Trophic statusSitu GedeFisheryChlorophyll-aFish Reserve

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 ?Scm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.J. Environ.

Monitoring of environmental factors allows the achievement of some important objectives regarding water quality, forecasting, warning and intervention. The aim of this paper is to investigate water quality parameters in some potential pollutant sources from northern, southern and east-southern areas of Romania. Surface water quality data for some selected chemical parameters were collected and analyzed at different points from March to May 2017.

This study was conducted in order to understand the taste and odour problems that occurred in the Seine and the Marne rivers during the severe drought of 1976. Samples were taken every 15 days from several locations in the rivers themselves and from storage reservoirs upstream from Paris. Algae and actinomycetes were identified and counted. Metabolite concentrations were measured. These data were correlated with threshold odor numbers and bacteriological water quality parameters.
