The present investigation took place at Habbaniya lake to assess the level of pollution as an overall index besides organic directories. Dissolved Oxygen, Biological Oxygen Demand and Chemical Oxygen Demand were calculated for 16 samples of lake water in addition to parameters of Overall Index Pollution. The lake water content of Dissolved Oxygen is excellent and unpolluted according to Biological Oxygen Demand, and Chemical Oxygen Demand values (Dissolved Oxygen varied from 9.100 mg l-1 to 13.600 mg l-1, Biological Oxygen Demand varied from 2 mg l-1 to 7 mg l-1, and Chemical Oxygen Demand varied from 30 mg l-1 to 73.667 mg l-1). Overall Index Pollution was useful and helpful in determining lake water quality. The situation of the lake was better compared to the year 2014. The health status of the lake varied from acceptable to slightly polluted due to having Overall Index Pollution values ranges from 1.632 to 2.677, and it supports aquatic life in it. The map of Overall Index Pollution shows that the values in the northwestern part of the lake are lower than in the southeastern part due to the continuous renewal of water in the first part because it represents a water inlet. This map is almost identical to a distribution map of Dissolved Oxygen, Biological Oxygen Demand, and Chemical Oxygen Demand. In general, Habbaniya lake is non-polluting and not dangerous to the environment now, but it may face the risk of pollution, based on the results obtained. Thus, the present study concluded that the use of the Overall Index Pollution technique with organic indicators is very suitable for assessing the level of water pollution in Habbaniya lake.

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.

Sebagian besar air dipakai sebagai air untuk pembilas, sebagai contoh air bersih yang digunakan untuk mandi dan cuci. Namun, kebutuhan akan air baku yang besar tidak diikuti dengan persediaan air baku, baik secara kuantitas maupun kualitas. Salah satu cara untuk mengatasi masalah ini adalah dengan memanfaatkan kembali (reuse) efluen hasil pengolahan air limbah. Pada penulisan ini cara mengelolah air limbah domestik menggunakan sistem lahan basah buatan yang menggunakan tanaman air dalam skala lapangan. Penulisan ini bertujuan mengetahui efisiensi penurunan kadar Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) dan Dissolved Oxygen (DO) yang terkandung dalam limbah cair domestik pada suatu daerah. Metode penulisan dengan cara mengaklamatisasi tanaman selama 12 hari sebelum ditanamkan ke lahan basah buatan kemudian mengukur efisiensi penurunan kadar efluen. Hasil percobaan menunjukkan bahwa dengan menggunakan tanaman air dalam sistem lahan basah buatan dapat penyisihan kandungan pencemar dalam air limbah dengan waktu tinggal 2 hari. Keunggulan pengolahan air limbah dengan sistem ini selain kualitas hasil air pengolahan yang sesuai baku mutu air limbah domestik juga dapat meningkatkan kualitas tanah.

Global climate change induced by increased concentrations of greenhouse gases (especially CO2) is expected to include changes in precipitation, wind speed, incoming solar radiation, and air temperature. These major climate variables directly influence water quality in lakes by altering changes in flow and water temperature balance. High concentration of nutrient enrichment and expected variability of climate can lead to periodic phytoplankton blooms and an alteration of the neutral trophic balance. As a result, dissolved oxygen levels, with low concentrations, can fluctuate widely and algal productivity may reach critical levels. In this work, we will present: 1) recent results of GCMs climate scenarios downscaling project that was held at the University of Derby, UK.; 2) current/future comparative results of a new mathematical lake eutrophication model (LEM) in which output of phytoplankton growth rate and dissolved oxygen will be presented for Suwa lake in Japan as a case study. The model parameters were calibrated for the period of 1973–1983 and validated for the period of 1983–1993. Meterologic, hydrologic, and lake water quality data of 1990 were selected for the assessment analysis. Statistical relationships between seven daily meteorological time series and three airflow indices were used as a means for downscaling daily outputs of Hadley Centre Climate Model (HadCM2SUL) to the station sub-grid scale.

A 3-year study was conducted by the U.S. Army Corps of Engineers assessing water quality related impacts of aquaculture of 250,000 channel catfish (Ictalurus punctatus) in floating net pens in the Rock Creek Arm of Lake Texoma, Oklahoma/Texas. Five large nylon nets suspended from a floating framework of galvanized metal anchored in open water 100 m offshore made up the net pens with fish stocking densities varying from 88 to 219 fish/m3. Water quality sampling was conducted biweekly from April to September and monthly from October to March at three locations. On all sampling dates field measurements of water temperature, pH, dissolved oxygen, and conductivity were recorded at 1 m depth intervals and water samples were collected at a depth of 0.5 m and near the bottom of the water column at each site. Sample analyses included: total alkalinity, total hardness, turbidity, chloride, sulfate, orthophosphate, total phosphorus, nitrate-N, nitrite-N, total Kjeldahl nitrogen, total organic carbon, dissolved organic carbon, biochemical oxygen demand, and chlorophyll a. The results showed statistically significant decreases in water temperature and dissolved oxygen and significant increases in field conductivity in surface waters near the net pens relative to other sampling sites. The most dramatic water quality effect observed during the study was decrease in dissolved oxygen levels near the net pens following lake turnover in the second year.

The study investigated the pretreatment of real paracetamol (PCT) wastewater of a pharmaceutical industry by Fenton process. At the best experimental conditions (COD/H2O2 = 1/1, Fe+2/H2O2 = 1/70, settling method:centrifuging, pH 6 at settling step), 92.7, 92.7, 95.5, 99.1, 99.9 and 99.4% of chemical oxygen demand (COD), total organic carbon (TOC), 5-day biological oxygen demand (BOD5), PCT, para-amino phenol (PAP) and aniline were removed, respectively. Changes in the concentrations of these parameters were also investigated for both oxidation and settling steps of Fenton process. It was found that COD and TOC were removed at the settling step (precipitation) whereas PCT, PAP and aniline were removed at the oxidation step. Mass balance calculations were also studied to show the mass distributions of COD in different phases (gas + foam, effluent and sludge). Fenton process was found as an effective method for the pretreatment of real PCT wastewater for discharging in a determined collective treatment plant.

Gomati River originate from Madhoganj Tanda village in Pilibhit district, U.P. it passes through the district of Shahjahanpur, kheri, Hardoi, Sitapur, Janpur and ultimately merge in Ganga. River water is significant for every living organism as well as aquatic life. Water pollution is a major global problem. Modernization and urbanization have polluted the river water and degraded the status. All over the world we are seeing that drain is the main source of water pollution especially for rivers flowing within the city. This drain generally carries industrial effluent, domestic waste, sewage and medicinal waste resulting in poor water quality. Gomati River receives industrial as well as domestic waste from various drains of Lucknow city. As Gomati river is the only source of surface water near the communities. A total 20 parameters namely Temperature, pH, Turbidity, Conductivity, Total dissolved solids (TDS), Total suspended solids (TSS), Total solids (TS), Dissolved oxygen (DO), Biological oxygen demand (BOD) Chemical oxygen demand (COD), Alkalinity, Total hardness, Calcium as ca, Magnesium as Mg, Chloride, Fluoride, Sulphate as So4, Nickel as Ni, Lead as Pb, and Zinc as Zn where analysed and their variation is discussed to obtain the impact of effluents on water quality. From the result it was found higher than the permissible limit of WHO and BIS.
