Musi River

Penelitian ini dilakukan untuk mengetahui kualitas air Sungai Musi tahun 2007 sampai dengan 2008 di bagian tengah dan hilir berdasarkan pada sumber polutan. Empat belas stasiun pengambilan contoh ditetapkan sebagai sumber polutan seperti industri maupun pemukiman penduduk, dan referensi yang jauh dari industri maupun pemukiman yang digunakan sebagai pembanding. Pada setiap stasiun, pengambilan contoh dilakukan 3 kali waktu pengambilan, yaitu bulan April, Juni, dan Januari yang dapat mewakili 3 musim yang berbeda pada tahun tersebut. Beberapa parameter diukur in situ sementara beberapa lain dianalisis di laboratorium dengan standar methods (AWWAWEF, 2005). Dari hasil penelitian didapatkan bahwa industri yang bergerak di bidang pengolahan kelapa sawit dan karet cenderung menurunkan kualitas perairan di Sungai Musi. Kandungan logam berat dalam sedimen di Sungai Musi relatif rendah dengan kandungan Cr+6 dan Pb yang tertinggi masing-masing 13,481 dan 1,747 μg per g. Curah hujan cenderung menurunkan beberapa parameter fisika dan kimia kualitas perairan. Potensi pencemaran cenderung ditemukan di bagian hilir Sungai Musi, karena sebaran industri dan intensitas pemanfaatan perairan cukup tinggi di bagian sungai tersebut. Study in order to know distribution of pollution source and its effect on water quality of the middle and down stream of Musi River was conducted in April and June 2007 and January 2008. Fourteen sampling sites were selected based on the pollution source and the minimal degradation site (reference sites). Parameters observed were pollution source distribution and water and sediment parameters such as physical and chemical parameters. Water sample was collected at 0.5 m from water surface by using Kemmerer water sampler while sediment samples were taken by using Ekman grab. Some of the parameters were analyzed in situ while the rest were analyzed in laboratory. Results indicated that oil palm and rubber industries were mostly the pollution source in Musi River. Potential pollution source was mostly found in the middle and down stream of Musi River since most of pollution source and high water utilization found in this area. Water quality parameters except total suspended solid and biochemical oxygen demand, were still in the range that can be tolerated by the aquatic organisms. Rain fall tends to decrease water quality of the river. Concentration of heavy metal such as Chrom (Cr+6) and plumbum in the sediment were in still in low concentration with the highest concentration reaching 13.481 and 1.747 μg per g respectively.

This study focuses on rainwater harvesting quality at the Faculty of Engineering, International Islamic University Malaysia (IIUM). As development is progressing over the years in Malaysia, there is also an increasing number of environmental issues and those issues are getting worse day by day. At present, Malaysia is blessed with plentiful annual rainfall that represents approximately 314 mm of monthly rainfall but there is no evidence that this rainwater is redirected for daily usage. To pursue a more sustainable development, rainwater harvesting has been recognized as one innovative solution. The IIUM Gombak campus is located in a hillside area that is a suitable study area to perform rainwater harvesting, which can be used as an alternative water supply in the future and reduce utility bills for water used on the campus. Firstly, a suitable study area for rain water harvesting around KOE, IIUM was determined before collection of data to determine the storage capacity needed. This study includes the estimation of rainwater quantity that can be harvested in one year. The quality of rainwater in terms of biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH, total suspended solid (TSS), turbidity, and microbial count were studied. Data analysis showed that the values of BOD, COD, pH, TSS, turbidity, and microbial count were in the range of 2 - 3.2 mg/l, 22.5 – 42.5 mg/l, 5.9 - 6.5, 20 mg/l, 9 -11 NTU, and between 200 -260 cfu/ml, respectively. This indicates that the harvested rainwater is acceptably clean but not suitable to be used as drinking water. ABSTRAK: Fokus kajian ini adalah pada kualiti air hujan yang ditadah di Fakulti Kejuruteraan, Universiti Islam Antarabangsa Malaysia (UIAM). Sejajar dengan pembangunan pesat di Malaysia, isu alam sekitar juga semakin bertambah dan menjadi semakin teruk hari ke hari. Pada masa sama, ketika ini Malaysia dirahmati dengan hujan yang mencurah setiap tahun, dengan kuantiti bulanan sebanyak 314 mm air hujan dan tidak ada bukti penggunaan air hujan ini bagi kegunaan harian dsb. Bagi memenuhi keperluan kelangsungan pembangunan, penadahan air hujan dikenal pasti sebagai satu penyelesaian inovatif. Kampus UIAM Gombak terletak di kawasan pinggiran bukit yang sesuai bagi menjalankan kajian tadahan air hujan. Ianya boleh digunakan sebagai bekalan air alternatif pada masa depan dan mengurangkan bil utiliti bekalan air dalam kampus. Terlebih dahulu, kawasan kajian yang sesuai dikenal pasti berdekatan Fakulti Kejuruteraan, UIAM bagi mengumpul air hujan sebelum data dikumpulkan bagi mengenal pasti kapasiti pengumpulan yang diperlukan. Kajian ini juga menganggar kuantiti air hujan yang boleh ditadah dalam satu tahun. Kualiti air hujan dikaji dari segi keperluan oksigen biokimia (BOD), keperluan oksigen kimia (COD), pH, jumlah pepejal terampai (TSS), kekeruhan dan bilangan mikrob. Analisis data mendapati nilai BOD, COD, pH, TSS, kekeruhan dan bilangan mikrob berada dalam julat 2 - 3.2 mg/l, 22.5 – 42.5 mg/l, 5.9 - 6.5, 20 mg/l, 9 -11 NTU dan antara 200 -260 cfu/ml, masing-masing. Ini menunjukkan air hujan yang ditadah adalah boleh diterima sebagai bersih tetapi tidak sesuai dijadikan sebagai air minuman

Abstract In this study, the variables of zooplankton and water quality were investigated in the Can Giuoc River, Southern Vietnam. Zooplankton was monitored in April and September 2015 at 5 sampling sites in the river. Some basic water quality parameters were also tested, including pH, total suspended solid (TSS), dissolved oxygen (DO), biological oxygen demand (BOD5), inorganic nitrogen (NH4+), dissolved phosphorus (PO43−), and coliform. The zooplankton biodiversity indices were applied for the water quality assessment. The results showed that pH ranged from 6.7 to 7.6 during the monitoring. The TSSs were between 34–117 mg/L. The DO and BOD5 were from 0.6 to 3.8 mg/L and from 6.3 to 13.2 mg/L, respectively. The NH4+ and PO43− concentrations ranged from 0.44 to 3.23 and from 0.08 to 1.85 mg/L, respectively. The coliform number was between 9.3×103–9.3×104 MPN/100 mL. The zooplankton analyses showed that there were 31 species of coelenterates, rotatoria, oligochaetes, cladocerans, copepods, ostracods, mysidacea, and 8 larval types. Thereof, the species of copepods were dominant in the species number. The zooplankton density ranged from 9 500 to 23 600 individuals/m3 with the main dominant species of Moina dubia (Cladocera), Thermocyclops hyalinus, Acartia clausi, Oithona similis (Copepoda), and nauplius copepods. The biodiversity index values during the monitoring were from 1.47 to 1.79 characteristic of mesotrophic conditions of the aquatic environment. Besides, the species richness positively correlated with pH, TSS, DO, BOD5, NH4+, PO43−, and coliform, while the zooplankton densities got a positive correlation with DO, BOD5, NH4+, PO43−, and coliform. The results confirmed the advantage of using zooplankton and its indices for water quality assessment.

Abstract This study aims to enhance the mapping of forecast for water quality assessment in Mekong Delta provinces. The data from 32 sites from main rivers and canals in an area of around 2,482 km2 in Tien Giang Province, Vietnam, were used for calculation and mapping. The ArcGIS 9.3 software, Inverse Distance Weighting (IDW) interpolation method, hydrologic data, and water quality parameters in March (2010-2014) were applied to build the maps showing 2020 water quality predictions for main rivers and canals in Tien Giang Province. The estimation was based on the Water Quality Index (WQI) with 6 parameters such as pH, total suspended solid (TSS), dissolved oxygen (DO), biochemical oxygen demand (BOD), total nitrogen (T_N), and coliform. The results showed that water quality in the studied area in dry season will not be improved by the year 2020. The finding could be a scientific reference for the selection of effective approaches to improve water quality in main rivers and canals in Tien Giang Province.

Water Constituents

Unoccupied aircraft systems (UAS, or drones) equipped with off-the-shelf multispectral sensors originally designed for terrestrial applications can also be used to derive water quality properties in coastal waters. The at-sensor total radiance a UAS measured constitutes the sum of water-leaving radiance (LW) and incident radiance reflected off the sea surface into the detector’s field of view (LSR). LW is radiance that emanates from the water and contains a spectral shape and magnitude governed by optically active water constituents interacting with downwelling irradiance while LSR is independent of water constituents and is instead governed by a given sea-state surface reflecting light; a familiar example is sun glint. Failure to accurately account for LSR can significantly influence Rrs, resulting in inaccurate water quality estimates once algorithms are applied. The objective of this paper is to evaluate the efficacy of methods that remove LSR from total UAS radiance measurements in order to derive more accurate remotely sensed retrievals of scientifically valuable in-water constituents. UAS derived radiometric measurements are evaluated against in situ hyperspectral Rrs measurements to determine the best performing method of estimating and removing surface reflected light and derived water quality estimates. It is recommended to use a pixel-based approach that exploits the high absorption of water at NIR wavelengths to estimate and remove LSR. Multiple linear regressions applied to UAS derived Rrs measurements and in situ chlorophyll a and total suspended solid concentrations resulted in 37 and 9% relative error, respectively, which is comparable to coastal water quality algorithms found in the literature. Future research could account for the high resolution and multi-angular aspect of LSR by using a combination of photogrammetry and radiometry techniques. Management implications from this research include improved water quality monitoring of coastal and inland water bodies in order to effectively track trends, identify and mitigate pollution sources, and discern potential human health risks.
