ABSTRACT. Limnological Survey of three Tropical Water Reservoirs in Eastern India. Plankton communities of three water reservoirs of India reflect direct relationship with organic pollution. The assessment of water quality as high or low organically polluted for three water bodies have been achieved with help of algal community, which can be used as indicator of organic pollution. Algal pollution indices according to Palmer (1969) and Watanabe’s (1962) based on genus and species were used in rating water samples for high or low organic pollution. Among 26 genera found in India 20 most frequent and common genera of algae were taken into account for indexing pollution status. Water Quality Index (WQI) on the basis of weighting and rating of the chemical parameter was also used to correlate the Palmer index with Physical-chemical parameters of water reservoirs.Key Words. Palmer Index, organic pollution, water reservoir, algae, plankton, water quality index.RESUMEN. Estudio limnológico de tres embalses de la India Oriental. Las comunidades planctónicas de tres embalses de la India reflejan relaciones directas con la polución orgánica. Se ha evaluado la calidad del agua de estos embalses atendiendo a la comunidad algal que alojan, lo que puede usarse como indicador de polución orgánica. Se ordenaron las muestras de agua, desde alta hasta baja polución orgánica, de acuerdo con los índices de Palmer (1969) y Watanabe (1962) basados en géneros y especies. Entre los 26 géneros encontrados en la India, se seleccionaron los 20 más comunes y frecuentes para los cálculos de los índices citados. También se calculó el índice de la calidad del agua (Water Quality Index, WQI), y se correlacionó con el índice algal de Palmer así como con los parámetros físico-químicos del agua de los embalses.Palabras clave. Índice de Palmer, polución orgánica, embalses, algas, plancton, índice de calidad del agua.

Abstract The water spatio-temporal variability of the Irapé Hydroelectric Power Plant reservoir and its main tributaries was evaluated by analysing the temporal trend of the main parameters and applying the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI), considering data from 2008 to 2018. This reservoir is in Minas Gerais, Brazil, covering an area of approximately 142 km2, across seven municipalities. The dissolved iron (DFe) presented the highest percentage of standard violations (31.7% to 80.5%), with most frequencies being verified in the reservoir tributaries. The Mann–Kendall test indicated that the monitoring stations showed an increasing trend of 78.5% N–NH4+ and 64.1% DFe. During the evaluated period, the reservoir waters were classified as excellent (1.2%), good (61.3%), acceptable (29.5%), and poor (8.0%) according to the WQI for the proposed use. The poorest quality classes were more frequent in the tributaries, especially in the year 2009. The WQI seasonal assessment indicated a worsening during the rainy period in 57% of the stations, as a result of external material transport to the water bodies. The CCME WQI, in conjunction with temporal statistical analysis, contributed to the monitoring data interpretation, generating important information for reservoir water quality management.

Based on the water quality investigation data in December of 2010, the water environment quality of Jilongshan sea area in Zhanjiang in winter was assessed using single water quality parameter model, integrated water quality index model, organic pollution index model and eutrophication assessment model. The results show that the key pollutants are dissolved inorganic nitrogen (DIN) and chemical oxygen demand (CODmn), with their average concentrations of 1.39 and 3.74mg/L, respectively. And the averages of their single parameter pollution index are 3.48 and 0.93. Jilongshan sea area is seriously polluted by DIN. None of the sampling stations are able to meet the third-rate seawater standard in the sea area. From the evaluation results, the N/P ratio is higher than Redfield ratio. DIN is the most important contribution factor to the eutrophication. The averages of single parameter pollution index, integrated water quality index, organic pollution index and eutrophication index are 1.09, 2.58, 3.78 and 22.5, respectively. Most parts of Jilongshan sea area are polluted moderately. According to the evaluation mode of organic pollution and eutrophication index, the organic pollution degree reaches the forth level and the eutrophication degree in Jilongshan sea area is very serious.

ABSTRAK Sungai Banjir Kanal Barat merupakan saluran utama drainase kota. Pembuangan limbah deterjen yang langsung ke saluran drainase tanpa adanya pengolahan terlebih dahulu, mengakibatkan peningkatan beban pencemaran dan penurunan kualitas air di Sungai Banjir Kanal Barat. Pencemaran deterjen dapat mengakibatkan eutrofikasi di perairan sungai, karena senyawa fosfat yang terdapat di dalam deterjen memacu pertumbuhan fitoplankton dan mengakibatkan blooming fitoplankton. Penelitian dilakukan pada bulan Februari – Maret 2016 di Sungai Banjir Kanal Barat yang bertujuan untuk mengetahui beban pencemaran limbah deterjen, mengetahui Indeks Kualitas Air (IKA), mengetahui konsentrasi deterjen dan kelimpahan fitoplankton, serta menganalisis hubungan konsentrasi deterjen dengan fitoplankton. Metode yang digunakan adalah metode survey dengan teknik purposive sampling. Lokasi sampling dibagi menjadi 3 stasiun dan 3 titik bagian (tepi, tengah, tepi) sungai. Pengambilan sampel air menggunakan metode integrated sample atau sampel gabungan tempat, sedangkan pengambilan sampel fitoplankton dilakukan secara pasif dengan metode penyaringan. Hasil penelitian menunjukkan konsentrasi deterjen di lokasi penelitian berada dalam kisaran 0,05-0,62 mg/l. Kelimpahan fitoplankton tertinggi pada semua stasiun adalah Trichodesmium sp., dimana Trichodesmium sp. merupakan indikator adanya pencemaran organik. Berdasarkan analisis regresi, kelimpahan fitoplankton dipengaruhi oleh konsentrasi deterjen sebesar 31,4% dan sisanya 68,6% dipengaruhi faktor lain. Beban pencemaran deterjen di Sungai Banjir Kanal Barat berkisar antara 13,18-215,67 ton/tahun. Indeks Kualitas Air Sungai Banjir Kanal Barat yaitu berkisar antara 1-5 yang tergolong dalam perairan sangat bersih-tercemar berat dan tidak baik digunakan untuk kegiatan perikanan.            Kata Kunci       : Deterjen; Kelimpahan Fitoplankton; Beban Pencemaran; Indeks Kualitas Air; Sungai Banjir Kanal Barat  ABSTRACT Banjir Kanal Barat River is the main drainage channel of the city. Waste disposal detergent into drainage without any waste treatment liquid first, caused in increase load pollution detergent and decrease of water quality in Banjir Kanal Barat River. Detergent pollution can cause eutrophication in the river, because phosphate compounds contained in detergent can stimulate phytoplankton growth and phytoplankton blooming. The study was conducted in February 2016 - March 2016 at Banjir Kanal Barat River which aimed to analyzing the load pollution and Water Quality Index (WQI), determine the concentration of detergent and abundance of phytoplankton, analyzing relation between detergent concentration with abundance of phytoplankton.

This study takes a look into groundwater quality at Ugbor Dumpsite area using water quality index (WQI), 2-Dimensional (2-D) geophysical resistivity tomography and vertical electric sounding (VES).The geophysical resistivity methods employed revealed the depth to aquifer, the geoelectric layers being made up of lateritic topsoil, clayed sand and sand. Along the trasverse line in the third geoelectric layer of lateral distance of 76 m to 100 m is a very low resistivity of 0.9 to 13 m from a depth range o f about 3 to 25 m beneath the surface- indicating contamination. Water samples were collected and analyzed at the same site during the raining season and during the dry season. The value of water quality index during the raining season was 115.92 and during the dry season was 147.43. Since values at both seasons were more than 100, it implies that the water is contaminated to some extent and therefore poor for drinking purpose. The Water Quality Index was established from important analyses of biological and physico-chemical parameters with significant health importance. These values computed for dumpsite area at Ugbor were mostly contributed by the seasonal variations in the concentrations of some parameters, such as, conductivity, total dissolved solids, hardness, alkalinity, chlorides, nitrates, calcium,  phosphates, zinc, which showed significant differences (P<0.01 and P<0.05) in seasonal variation.
