The physico-chemical and phytoplankton characteristics of the Tons River were analyzed during August 2011-July 2012. The samples were collected from Garhi Cant (Site 1) and Tapkeshwar temple (Site 2) at Dehradun. The results showed that temperature, velocity, DO, nitrate and phosphate affected the phytoplanktonic diversity of river Tons. Thirty five genera of phytoplankton belonging to three families of Chlorophyceae, Bacillariophyceae and Myxophyceae were also identified in the river water. The family Bacillariophyceae was dominating the river with much abundance throughout the study period. Bacillariophyceae was recorded with the maximum of 222.25±90.84 Unit/L at sampling site 1 and 239.08±125.41 Unit/L at sampling site 2. The greater number of individuals was in family Bacillariophyceae (239.08±125.41 Unit/L) followed by Chlorophyceae (183.75±112.50 Unit/L) and Myxophyceae(40.91±36.16 Unit/L) during the study period. Both the number of genera and number of individuals belonging to each genera was maximum in case of family Bacillariophyceae followed by Chlorophyceae and Myxophyceae. The present study revealed that the water quality of river Tons was fairly good for the growth and survival of phytoplankton, and as a result it sustains the higher phytoplankton diversity of Tons river.

Diyala River

Diyala River is a tributary of Tigris River, it is one of the important rivers in Iraq. It covers a total distance of 445 km (275 miles). 32600 km2 is the area that drains by Diyala River between Iraqi-Iranian borders. This research aims to evaluate the water quality index WQI of Diyala River, where three stations were chosen along the river. These stations are D12 at Jalawlaa City at the beginning of Diyala River, the second station is D15 at Baaquba City at the mid distance of the river, and the third station is D17 which is the last station before the confluence of Diyala River with Tigris River at Baghdad city. Bhargava method was used in order to evaluate the water quality index for both irrigation and drinking uses. The results indicated that Diyala river water quality at its beginning was excellent for irrigation and good for drinking, while at the mid distance of the river, it was good for irrigation but heavily polluted and unsafe for drinking. Water quality of the river at the third site was acceptable for irrigation but again severely polluted and unsafe for drinking.

This study was carried out to assess the water quality of Nasarawa using benthic macroinvertebrates as bioindicators. Biological monitoring working party (BMWP) scoring system was the index used to assess the ecosystem health of Nasarawa reservoir. A total of 4460 macrobenthic invertebrate comprising three phyla, three classes, six families and seventeen species were recorded. The overall macrobenthic population at the different stations revealed that the study area was dominated by Mollusca (41.18%), Oligochaetae (23.53%), Coleoptera and Diptera (11.77%), Mollusca (29.06%), Ephemerophtera and Odonata (5.89%). (BMWP) score of 65.7 was obtained for Nasarawa reservoir which classifies the reservoir as moderately polluted. Higher BMWP score of 65.7 was recorded in the wet season compared to the dry season value of 58.7. More macrobenthic invertebrate population was recorded in the dry season than in the wet season in Nasarawa reservoir. Simpson (1-D), Shannon (H) and evenness were higher during the dry season than in the wet season but dominance was higher in the wet season. Species richness as revealed by the Margaleff and Menhinick index was higher during the wet season than in the dry season. The variations in taxa and number of individuals during the months of sampling was not significantly different (P>0.05). It was found that agricultural activities, washing and bathing could alter physico-chemical parameters of the stream and hence changing the abundance of macroinvertebrates as well as the quality of water. This study, therefore, recommends that the source of pollutants should be controlled and the stream regularly monitored by the relevant authorities.

The study was conducted to determine the status of physico-chemical parameters of the Brahmaputra river water in Sherpur district and also to assess the monthly variation of the river water. To perform the study the samples were collected from five different stations during the period of December 2013 to May 2014. Various water quality parameters such as transparency, temperature, electrical conductivity (EC), total dissolved solids (TDS), pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), hardness and alkalinity were examined. The study revealed that a slightly variation in water quality at different stations of the river. The mean value of transparency (42.21 cm), temperature (23.38oC), EC (351.12 ?s/cm), TDS (178.54 mg/l), pH (7.75), DO (4.47 mg/l), BOD (1.02 mg/l), hardness (82.36 mg/l) and alkalinity (98.63 mg/l) showed that the present status of the Brahmaputra river water is suitable for all aquatic lives, domestic and agricultural uses. Although the overall status of the river water quality is suitable, degradation was detected in few points which might be due to anthropogenic activities, especially the direct discharge of domestic effluents into river. Thus, necessary initiatives should be taken against such anthropogenic activities to maintain the overall water quality of the Brahmaputra river for its sustainable use.Bangladesh J. Sci.

The river Kirtankhola has great importance in southern part of Bangladesh due to its necessity in transportations, municipal and agricultural purposes. But the ecological status and impacts of water quality on phytoplankton diversity were undiscovered. To cover the maximum area of the river, water samples were collected from the 6 locations (ST) covering about 13 km. Some parameters were measured immediately after sampling by portable devices and others done in laboratory following standard methods. The overall quality of the water was found good according to water quality guidelines of World Health Organization, although the water of port area showed comparatively high SO42- and CO3- values which attracts attention for future monitoring. ST 6 showed comparatively more alkaline water (pH 8.45) along with highest EC, TDS, NO3-, NH4+ and DIP values. Besides, 53 phytoplankton taxa belonging to Cyanophyceae (6), Chlorophyceae (10), Euglenophyceae (12) and Bacillariophyceae (25) were identified from the river. Scenedesmus acuminatus was found commonly in five stations except ST 1, whereas Euglena chlamydophora (ST 1), Gomphonema olivaceum (ST 3) and Cymbella parva (ST 5) found rarely. Highest diversity was counted in ST 6. Moreover, Chlorophyceae and Bacillariophyceae have positive correlation with several physical parameters, whereas Cyanophyceae negatively correlated. Euglenophyceae has both negative and positive correlations with some physico-chemical parameters. However, this was first attempt to measure diversity of primary producers and their correlations with water quality of Kirtankhola River.

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.

AbstrakSungai Klampok mengalir melalui Kecamatan Bergas dan sekelilingnya terdapat beberapa industri sehingga mengakibatkan sungai tersebut tercemar karena menjadi badan penerima air limbah. Akibat penurunan kualitas air Sungai Klampok akan berimbas pada penurunan kualitas air tanah yang digunakan oleh penduduk sekitar sungai tersebut. Penelitian ini bertujuan untuk mengetahui kualitas air tanah yang berada di sekitar Sungai Klampok sebagai akibat adanya pengaruh beban pencemaran oleh air limbah industri berdasarkan Permenkes No. 416/MENKES/PER/IX/1990 tentang persyaratan kualitas air bersih. Lokasi pengambilan sampel air sungai dibagi menjadi 3 stasiun (LK1, LK2 dan LK3) sedangkan untuk sampel airtanah dari rumah-rumah penduduk dilakukan pada 6 titik yaitu 3 titik di daerah utara dari Sungai Klampok (U1,U2, U3) dan 3 titik di daerah selatan dari Sungai Klampok (S1,S2, S3). Pengambilan sampel dilakukan pada musim kemarau. Dari hasil uji kualitas air sungai, pencemaran yang terjadi pada air sungai Klampok masuk dalam kategori tercemar ringan-sedang. Sedangkan hasil uji kualitas air tanah masih berada di bawah baku mutu yang disyaratkan oleh Permenkes No. 416/MENKES/PER/IX/1990, sehingga penurunan kualitas air sungai Klampok tidak mempengaruhi kualitas air tanah di sekitar sungai tersebut. AbstractThe Klampok River flows through the Bergas Subdistrict and there are a number of industries around it, causing the river to become polluted because it becomes the body of the recipient of wastewater. As a result of the decline in the quality of the water in the Klampok River, it will impact on the quality of groundwater used by residents around the river. This study aims to determine the quality of groundwater around the Klampok River as a result of the influence of pollution load by industrial wastewater based on Permenkes No. 416 / MENKES / PER / IX / 1990 concerning requirements for clean water quality. The location of river water sampling is divided into 3 stations (LK1, LK2, and LK3) while for groundwater samples from residential houses is carried out at 6 points, namely 3 points in the northern area of Klampok River (U1, U2, U3) and 3 points in the area south of the Klampok River (S1, S2, S3). Sampling is done in the dry season. From the results of the test of river water quality, pollution that occurs in Klampok river water is categorized as mild-moderate polluted. While the results of groundwater quality testing are still below the quality standards required by Permenkes No. 416 / MENKES / PER / IX / 1990 so that the decline in the water quality of the Klampok river does not affect the quality of groundwater around the river.
