Seasonal variations water quality of Nche stream in carried out using standard methods. The study lasted between April, 2014-March, 2015. Results obtained revealed that pH of the Nche stream varied from 6.41-6.87 in rainy season to 5.50-6.10 in dry season. Mean values for total solid, total dissolved solid, and total suspended solid for rainy season were 208.32 mg/l, 91.81 mg/l, and 116.50 mg/l respectively, while 139.88 mg/l, 72.47 mg/l, and 67.40 mg/l were the respective mean values for total solid, total dissolved solid and total suspended solid in dry season. Bacterial isolates from the stream include Actinomyces sp., Bacillus sp., Staphylococcus sp., Lactobacillus sp, Streptococcus sp., Achromobacter sp., Klebsilla sp., Salmonella sp., Escherichia sp., Acinetobactor sp., Serratia sp., Proteus sp., Enterobacter sp., Vibrio sp., Shigellasp, Flavobacterium sp., Citrobacter sp., Micrococcus sp., and Pseudomonas sp., while saprophytic mould isolates were Penicilum sp., Aspergillus sp., Penicillium sp., Fusarium sp., Cladosporium sp., Rhizopus sp., and Geotricum sp. Levels of cadmium for Nche stream from August to the rest of dry season as observed did not fall within WHO limit. Mean values of THBC, THUB, TCC, SCC, TVB, and TFC observed in the studied stream water were higher in rainy seasons than dry season and high than their respective WHO limits. The ability of cadmium heavy metal to accumulate in the body and the infective nature of the isolated organisms could pose a problem to the locals who consume water from this stream without further purification. There is need to inform the local population on the seasonal pollution status of Nche stream since they heavily depend on this stream as a source of domestic water. This study has evaluated the seasonal water quality of Nche stream, a water body in Imo State, Nigeria.

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.

Abstract The current development of aquaculture raises problems in the form of pollution of liquid waste generated during the production process. Aquaculture wastewater contains very high concentrations of inorganic nutrient. This study aims to determine the effectiveness of Sargassum polycystum density as a biofilter to reduce nitrate and phosphate in whiteleg shrimp pond. The study was conducted experimentally at indoor tank culture using a Completely Randomized Design (CRD) consisting of 3 density treatments with 3 replications, which were 1 gL−1, 2 gL−1, and 3 gL−1. The parameters observed were water quality such as nitrate, phosphate, temperature, salinity, pH, DO (Dissolved Oxygen), TSS (Total Suspended Solid), and TDS (Total Dissolved Solid); and also Saragassum’s growth. The results showed that the density of 3 gL−1 able to reduce nitrate 80% and phosphate 86,30%. The growth of S. polycystum for the three treatments decreased due to several factors, such as low nitrogen availability, environmental conditions, predators, and differences in stocking density. The average water quality measured during the study was temperature 27.84 °C; salinity 31.31 ppt; DO 4.72 mgL−1; pH 7.69; TDS 34.94 mgL−1; and TSS 4807.63 mgL−1. S. polycystum has the ability as biofilter for white shrimp culture because able to reduce nitrate and phosphate concentration. S. polycystum has potential benefits as alternative comodity candidate for polyculture and Integrated Multi Throphic Aquaculture (IMTA).

Gomati River

The river Gomati is popularly known as "Aadi-Ganga". Gomati River is an important tributary of river Ganga and perennial river of Awadh plains. The river Gomati originates from Gomat Taal near Madhoganj Tanda village in Pilibhit district (U.P.), run across the major part of U.P. covering nine districts of Shahjahanpur, Lakhimpurkheri, Hardoi, Sitapur, Lucknow, Barabanki, Sultanpur, Jaunpur and ultimately merges in Ganga river, near Saidpur Kaithi in Varanasi. The world is facing problems with a wide variety of pollutants both inorganic and organic in nature. Healthy soil, clean water and air are the soul of life. Often soil, water and air are no longer clean and pure, but pose human health risks. The river Gomati receives huge quantities of untreated sewage agricultural runoff, brings a lot of pesticides, fertilizer, street washouts bringing oil, asphalt, sediment and many types of heavy metals. From industrial effluents to domestic discharge, the river becomes more of a flowing dumping yard. The physico-chemical parameters in water of river Gomati were assessed to know about the water quality in its catchment area. Total of four sampling sites were selected between Gokul ghat upstream and Ramghat downstream. Physico-chemical parameters like pH, Temperature, Total dissolved solid (TDS), Total suspended solid (TSS), Hardness, Dissolved oxygen (DO), Nitrate, Nitrite, Chloride, Total Coliforms and some heavy metals were determined. Changes in water quality of river Gomati due to variations in quantity of parameters were found. Heavy metals mainly Copper, Iron, Zinc, Lead, Arsenic, Cadmium and Nickel were noticed.
