In Bahar County (Iran), rivers are among the important sources of water for the agricultural sector. Therefore, this research evaluated the parameters of temperature, pH, Total Dissolved Solids (TDS), turbidity, nitrate, total phosphate, dissolved oxygen (DO), Biological Oxygen Demand (BOD5), and fecal coliform at five stations for five months (from February 2015 to June 2015) to determine water quality in the rivers. Based on this evaluation, the NSFWQI index was calculated and, finally, the routes of the rivers were zoned. The best water quality was recorded at Station Number 3 with the NSFWQI Value of 80 in January, and the worst at Station Number 5 (latgah) with the NSFWQI Value of 37 in June. Based on the mean NSFWQI indices, water quality was Medium at Stations Number 1, 2, and 4, good at Station Number 3, and bad at Station number 5.

The Difference

The use of surface waters such as rivers for domestic, agricultural andindustrial purposes have made them vulnerable to pollution leading to impairedwater quality. The water quality of Lahug River in Cebu City was evaluated usingcoliforms as indicators, in relation with physicochemical parameters such as biological oxygen demand (BOD), conductivity, dissolved oxygen (DO), nitrate,pH, phosphate, salinity, temperature, total dissolved solids (TDS) and totalsuspended solids (TSS). Sampling was done once a month from November 2011to April 2012 in three stations covering the upstream, midstream and downstream.The multiple tube fermentation technique was used for the analysis of coliforms.The level of these indicator bacteria increased from the upstream towards thelower reaches of the river especially in the months of February to April; however,the difference in values across time was not significant. This implies that therewas a continuous fecal pollution in the river. There were no statistically significantcorrelations between FCs and TCs with the physicochemical parameters. Anegative relationship was observed among FCs and TCs with pH, TSS, DOand nitrate (p>0.05). These results suggest the presence of sewage and organicpollutants in the river.Keywords: Aquatic Ecology, water quality, coliform, physicochemical parameters,experimental design, Philippines

ABSTRACTThe aim of this study is to analyze the water quality parameters and bacterial diversity and thereby understand the effect of water quality on the microbial population structure in the river. The following parameters: total coliforms, chemical oxygen demand, harness, ammonium, nitrite, nitrate, total Kjeldahl nitrogen, dissolved oxygen, total phosphorus, total dissolved solids, and temperature were analyzing along 17 sampling points in the river. The worst levels of pollution were 510 mg/L chemical oxygen demand, 7 mg/L nitrite, 45 mg/L nitrate, 2 mg/L dissolved oxygen, and 756 mg/L of total dissolved solids. Whole metagenome shotgun sequencing was performed at 4 key points along the river (P1,P7,P10 and P17), the first point had clean water and the other points were polluted, as a result of this pollution, the structure of microbial communities along the river have changed. Proteobacteria and Bacteroidetes were the most representative phyla with a relative abundance of 57 and 43% respectively for P1, 82 and 15% for P7, 69 and 27% for P10 and 87 and 10% for the last point P17. P1 is rich in microorganism such as Limnohabitans a planktonic bacterium very common in freshwater ecosystems. However, in P7, P10 and P17 are rich in opportunistic pathogens such as Acinetobacter Arcobacter and Myroides that endangers the health of around 1.6 million people which live around the area. These results elucidate the influence of the pollution on the microbial community and the likely effects on the health of the people around.

The Mean

Anthropogenic activities such as industrial effluent, domestic and agricultural waste disposal constitute major sources of pollution in water. The effects of these pollutants on the physico- chemical properties of Lake Kivu, Rwanda were investigated at three locations (Gisenyi, Kibuye and Cyangugu) between February 2005 and December 2006. Water samples used for physico- chemical analysis were collected from 12 stratified points on the lake. Samples collected were analysed and interpreted using appropriate international procedures. The physico -chemical properties measured were temperature, conductivity, pH, transparency, salinity, total alkalinity, dissolved organic matter (DOM), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), nitrate – nitrogen, phosphate – phosphorus and sulphate. Mean water temperature measured (24.7 + 0.58 o C) was highest in Kibuye and lowest (24.5 + 0.31 o C) in Cyan gugu. The lake water was moderately hard with mean total alkalinity values of 88.1 ± 1.63mgL -1 ; 79.7 ± 2.36mgL -1 and 81.0 ± 2.46mg L -1 recorded in Gisenyi, Kibuye and Cyangugu respectively; salty and alkaline with mean pH values of 8.87 ± 0.07 in Gisenyi; 8.86 ± 0.06 in Kibuye and 8.91 ± 0.06 in Cyangugu. Total dissolved solids (TDS) level in the lake was above the 500mg L -1 prescribed by WHO while the mean biochemical oxygen demand (BOD) reading was within the range for unpolluted or moderately polluted lake. Water from the lake showed mineralization with mean conductivity values ranging from 1058 - 1184μS cm -1 in Gisenyi; 1058 - 1147μS cm -1 in Kibuye and 1031 - 1116μS cm -1 in Cyangugu. The mean dissolved oxygen values were below the 5mgl -1 limit recommended by WHO for fresh water fish species. SO 4- -2 and NO 3 – N concentration in the lake water does not constitute any serious health risk to both man and the aquatic organisms it supports. However, there is the need to constantly monitor the lake water to mitigate any build up of the ions to a hazardous level.

The study was conducted to investigate the effects of solid waste and industrial effluents on the water quality of Turag River. Both the upstream and downstream sampled water from the selected points were analyzed for color, odor, pH, electrical conductivity (EC), total dissolved solids (TDS), dissolved oxygen (DO), biological oxygen demand (BOD), copper (Cu), cadmium (Cd), iron (Fe), lead (Pb) and zinc (Zn) concentrations. Results of the study showed that the color of water was light to dark black and emitted noxious smell due to the industrial effluents. The upstream water was slightly alkaline with comparatively high DO content while low concentration of other parameters. The water after the solid waste and effluents received points as well as middle and downstream points was slightly alkaline with higher levels of other parameters when compared with upstream point. The minimum and maximum values of pH, EC, TDS, DO and BOD were 7.24-7.61, 425-2277 ?S/cm, 239-1349 ppm, 1.22-3.66 ppm and -2.44-0.86 ppm, respectively. The continuous dumping of waste materials resulted in a marked increase in the concentration of metals in the river water varied in the order of Fe > Zn > Pb > Cu > Cd. The study concluded that the downstream water in the river was almost polluted and unsuitable for human consumption and aquaculture purposes.DOI: http://dx.doi.org/10.3329/jesnr.v5i2.14817 J.

Kualitas air di suatu wilayah yang merupakan salah satu indikator lingkungan dapat dievaluasi menggunakan parameter fisika, kimia, dan biologi. Indeks Kualitas Air Indonesia (IKA-INA) dapat digunakan untuk menilai kondisi kualitas air secara menyeluruh pada lokasi dan waktu tertentu. IKA-INA dihitung dengan menggunakan sepuluh (10) parameter yaitu pH, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), NO3, NH3, Total Phosphate (TP) dan fecal coliform. IKA-INA tersebut merupakan indeks kualitas air yang dapat memberikan informasi secara sederhana. Dalam pemanfaatannya, tidak semua data parameter dalam IKA-INA tersebut dapat terpenuhi karena adanya data tidak valid atau data yang hilang. Kajian ini bertujuan untuk memberi alternatif rumusan IKA-INA dengan parameter yang tidak lengkap atau jika tidak semua data dalam parameters tersebut tersedia. Metode yang digunakan dalam menyusun rumusan adalah dengan melakukan koreksi faktor bobot parameter IKA-INA terhadap parameter yang hilang dan nilai Q (nilai sub-indeks). Setelah itu dilakukan uji coba pada nilai baku mutu air dalam Peraturan Pemerintah No. 22/2021 Lampiran VI serta pada data kualitas air sungai yang mewakili kualitas baik dan buruk. Hasil uji coba menunjukkan bahwa bobot parameter terkoreksi dapat digunakan untuk penanganan parameter yang hilang dalam penilaian kualitas air dengan metode IKA-INA. Hasil IKA-INA dengan parameter hilang yang menggunakan bobot terkoreksi dan hasil IKA-INA dengan parameter lengkap mayoritas memberikan status IKA yang tidak berbeda, kecuali untuk parameter fecal coli dan parameter yang mempunyai kadar jauh berbeda terhadap kondisi air secara keseluruhan.

Industri pengolahan alkali treated cottonii (ATC) menghasilkan limbah cair yang sangat besar. Pendaur ulangan limbah cair akan mengefisienkan penggunaan air untuk pengolahan sekaligus mengurangi masalah pencemaran lingkungan. Untuk itu dilakukan ujicoba proses daur ulang limbah cair ATC menggunakan alat yang dirancang oleh Balai Besar Riset Pengolahan Produk dan Bioteknologi Kelautan dan Perikanan yang berkapasitas 360 liter/jam. Pengolahan limbah cair dilakukan dengan teknik koagulasi dan filtrasi. Proses koagulasi dilakukan dengan penambahan bahan koagulan tawas (Al 2(SO4)3 ) dan flokulan blok di dalam tangki koagulasi, sedangkan filtrasi dilakukan dengan melewatkan limbah melalui kolom zeolit‑arang aktif dan filter selulosa asetat. Pengamatan dilakukan terhadap limbah cair dan air hasil olahan yang meliputi total padatan terlarut (Total Dissolved Solids/TDS), total padatan anorganik terlarut (Total Inorganic Dissolved Solids/TIDS), Biological Oxygen Demand (BOD), pH, kekeruhan, bau, dan warna limbah. Hasil penelitian menunjukkan bahwa pengolahan limbah cair ATC dapat menurunkan jumlah TDS, TIDS dan BOD hingga 56,60%, 32,29%, dan 60,66%, meskipun kemampuan alat filtrasi menggunakan kolom zeolit‑arang aktif menurun seiring dengan banyaknya proses daur ulang yang dilakukan. Berdasarkan hasil analisis didapatkan juga bahwa proses daur ulang limbah cair ATC mampu menurunkan nilai pH, kekeruhan, bau, dan warna limbah. Dengan pengolahan tersebut limbah cair dapat didaur ulang hingga 5 kali untuk proses pengolahan ATC berikutnya.

Sungai Banjir Kanal Barat dan Silandak merupakan sungai besar yang berada di Kota Semarang. Terdapat berbagai aktivitas di sepanjang aliran sungai tersebut, diantaranya aktivitas domestik dan industri dimana buangan limbah masuk ke dalam badan sungai sehingga menyebabkan penurunan kualitas perairan. Salah satu mikroorganisme yang terkandung dalam limbah domestik yang berperan sebagai indikator pencemaran yaitu bakteri coliform sehingga perlu dilakukan perhitungan total coliform guna mengetahui adanya pencemaran di Sungai Banjir Kanal Barat dan Silandak. Tujuan dari penelitian ini adalah untuk mengetahui kelimpahan total coliform, status mutu air berdasarkan PP Nomor 82 Tahun 2001 kelas II dan hubungan antara total coliform dengan bahan organik dan BOD (Biological Oxygen Demand) di Sungai Banjir Kanal Barat dan Silandak. Metode yang digunakan dalam penelitian ini yaitu metode survei. Pengambilan sampel terdiri dari 2 stasiun (A dan B) yang masing-masing terdapat 5 titik dan 2 kali pengulangan (P1 dan P2). Variabel utama yang dianalisis yaitu total coliform, bahan organik dan BOD, variabel pendukung yang diukur yaitu temperatur, salinitas, DO (Dissolved Oxygen ) dan pH. Berdasarkan hasil penelitian, jumlah total coliform pada stasiun A berkisar antara 240-16000 MPN/100 mldan 23-5400 MPN/100 ml pada stasiun B. Nilai total coliform pada titik A2 dan B2 pada P1 serta A5 P2telah melebihi bakumutu. Hubungan antara total coliform dengan bahan organik yaitu sangat lemah (nilaiPearson Correlation = 0,15). Hubungan antara total coliform denganBOD yaitu lemah (nilaiPearson Correlation= 0,378). Banjir Kanal Barat and Silandak Rivers are large rivers in Semarang. There are various activities along the river flow, including domestic activities and industries where waste effluents enter the river bodies causing a decrease in water quality. One of the microorganisms contained in domestic waste that as an indicator of pollution is coliform bacteria, so it is necessary to calculate the total coliform in order to find out the pollution in the Banjir Kanal Barat and Silandak Rivers. This study aims to determine abundance of total Coliform, water quality status based on PP No. 82 of 2001 class II and relationship between the total coliform with organic matter and BOD (Biological Oxygen Demand) in the Banjir Kanal Barat and Silandak Rivers. The method used in this study is survey method. Sampling consisted of 2 stations (A and B), each of which had 5  points and 2 repetitions (P1 and P2). The main variables analyzed were total coliform, organic matter and BOD, the supporting variable analiyzed were temperature, salinity, DO (Dissolved Oxygen ) and pH. Based on the results of the study, the total number of coliform at station A ranged from 240-16000 MPN/100 ml and 23-5400MPN/100 ml at station B. The total value of coliform at points A2 and B2 at P1 and A5 P2 has exceeded the standard. The relationship between total coliform and organic matter is very weak (Pearson Correlation value = 0.15). The relationship between total coliform and BOD is weak (Pearson Correlation value = 0.378).
