The paper presents an overview of recent physiochemical investigations on Dal lake with emphasis on lake, longterm water quality monitoring data from Lake and Water Development Authority (LAWDA1997-2017, published and unpublished data) with present analysis of Dal Lake to compare the water trends for pH, dissolved oxygen, chemical oxygen demand(COD),NO3 -N,Total Phosphorus(TP) and Transparency. The main sampling efforts include visit to 36 samplingsitesto find the past and future trend of these physio chemicalparameters(pH, DO, COD, NO3 -N, TP and Transparency).Maximum decreasing trendline was found for pH in Nigeen basin in summer season and lowertrends were found inNehru park basin in winter season. Maximum decreasing trendline was found for DO in Nigeen basin in summer season and lower trends were found in Nehru park basin in winter season. COD has shown maximum increasing trends in all basins mostly in Nigeen basin in summer season and lower decreasing trends in Hazratbal basin in autumn season, concentration of NO3 -N and TP have shown increasing trends in all basins of lake mostly in Nigeen basin in summer season and lower increasing trends in Nehru park basin in winter season. Trend of transparency has shown decreasing trends in all basins of lake particularly in Nigeen basin in summer season and lower trends can be seen mostly in Nehru park basin in winter season. Tourism influx,maximum use of pesticides and fertilizers in the horticultureandagriculture fields during the growing season (June–August) in the Dal Lake shows a drastic change of these parameters through these years and the influx of tourists visiting this lake has increased in the summer months which isresponsible for eutrophication of Dal Lake and needs serious managerial actions.

The Koshi river is the major tributaries of the Ganges which originates from the snowy peaks of Tibetan plateau in the central Himalayas. Its total catchment area is 60,400 km2, of which 28,140 km2 lies in Nepal, while the remainder is situated in Tibet. It passes from Nepal to India via the Koshi Tappu Wildlife Reserve area of Nepal. It destroys large area through floods, especially in India. This paper deals with the air temperature and phyco-chemical parameters like temperature, transparency, pH, oxygen, carbondioxide, alkalinity, hardness, chloride and biological oxygen demand of water of Koshi river at Kushaha area of Koshi Tappu Wildlife Reserve. The water temperature was recorded maximum in summer season but the transparency, pH, dissolved oxygen, total alkalinity and total hardness were recorded maximum in winter season. Similarly, free carbondioxide was maximum in rainy season and chloride and biological oxygen demand were recorded maximum in summer season. The air temperature and water temperature had positive and significant correlation with free carbondioxide and biological oxygen demand. Dissolved oxygen had positive and significant correlation with pH, total alkalinity and total hardness.

The water quality management of Ruhr River Association is challenged by the dual use pattern, i. e. drinking water supply and wastewater discharge simultaneously into the same river. In the past 10 years accidental or illegal pollution occurred statistically every twenty days. Identification of water pollutants (and polluters) was often impossible because water samples could not be secured for analysis in time. The water quality surveillance system could be extended with financial support of the European Union by another two automated monitoring stations equipped with sophisticated on-line analysators (e. g. for ammonia, chromium, chlorophyll fluorescence) and biomonitors using water fleas and mussels as detectors. Monitoring strategies, methods, techniques and costs for buildings, equipment and operation are reported. Experience and results obtained so far let assume that the integrated water quality monitoring is able to prove its merits concerning reconnaissance of accidental water pollution and subsequent early warning of water works.

The present study deals with phytoplankton population of Navule pond in Shivamogga during September 2014 to August 2015. Blue-greens constituted the major group (41.75%) followed by Chlorococcalas (36.68%), Diatoms (13.36%), euglenoids (7.35%) and Desmids (0.86%). The phytoplankton community was composed of 11 species of Blue-greens, 20 species of Chlorococcales, 18 species of Diatoms, 11 species of Euglenoids and 08 species of Desmids. Each group of phytoplankton showed different peak periods, the summer season produces relatively more phytoplankton than rainy and winter season. The variations in physico-chemical parameters are responsible for the fluctuation of quantity of phytoplankton.  The dominant genera recorded on the pond were Anabaenopsis sp., Ocillatoria sp., Euglena sp., and Phacus. Some of the pollution tolerant species identified during the present study are Scenedesmusquadricauda, Coelastrum sp., Tetraedonmuticum, Ocillatoria sp., Phormidium sp., Microcystis sp., Anabaena sp., Navicula sp., Synedra ulna, Cyclotella sp., and Pinnularia sp. In the present study Microcystisaeroginosa was recorded indicates the civic pollution.

Water quality monitoring is an important tool in determining the safety and suitability of water for various desired and intended uses. The procedures involved in the evaluation of water quality are numerous and multifaceted. Therefore, taking into consideration the specific objectives of water quality monitoring, sampling design is of vital importance. Most of the physical parameters of water quality are determined via in-situ measurements using modern testing equipment/field testing kits. Although there are some good field-based sensors that are being used for evaluation of water quality, the chemical parameters traditionally are mostly analyzed through laboratory-based experiments. This chapter is aimed to offer an inclusive knowledge and insights on the importance and assessment of physico-chemical parameters that are of high priority for monitoring the water quality of wetlands.

Abstract This research paper tries to identify and address issues related to efficiency of Sewage Treatment Plants (STPs) and their implications on the Dal Lake ecosystem in Srinagar city, Kashmir, India. Fluidized Aerobic Bioreactor (FAB) and Sequential Batch Reactor (SBR) technologies having been recently installed along the periphery of Dal Lake were evaluated for efficiency for a continuous period of 24 months from December 2016 to November 2018. Apart from chemical quality, total coliform (TC), fecal coliform (FC), and fecal streptococci (FS) analyses were also carried out. Major highlights of our work using one-way ANOVA (Analysis of Variance) revealed significant variations (p < 0.05) in Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), ammonia (NH3-N), total phosphorus (TP), TC, FC, and FS. Our findings indicate that both technologies are struggling for removal efficiency, which is very low, especially in FAB during three to four months of winter season where a very high drop in the working efficiency of the STP was observed. The treatment facilities did not meet the prescribed standards in respect of TSS, BOD, NH3-N, TP, TC, FC, and FS thereby having the potential to compromise public health and trophic status of Dal Lake.
