The purpose of this study was to determine the water quality based on some parameters of physical, chemical and biological properties of the three springs. One location site in the district of Kaliorang and then two location site in the District of Karangan. Landscape characteristics in the two districts almost equal in the hills with a small incision. Likewise, the third location of water sources is a hilly area of karst (limestone). Karst landscapes not only provide material goods, biodiversity, but also providers of ecosystem services such as clean water, the water regulator and the potential of the upper and lower surfaces such as caves. The results showed that the physical quality of water from the three water sources meet the quality standards required. From the results of laboratory testing, chemical water quality at three locations contain BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) is relatively high. The high value of BOD and COD indicated that the water conditions have polluted by the accumulation of organic materials, especially the litter of the forest vegetation. Furthermore, for total coliform and fecal coliform although the amount is below the threshold quality standards required, but its existence in the water indicates the contamination of water sources by sewage as from agricultural run-off, animal feces containing the bacteria, viruses, or disease-causing organisms more, Based on the designated class of water, the springs at the third location is very suitable for use as irrigation, facilities or infrastructure freshwater fish farming, recreation, and other designation that requires the same quality standards. As for the water designation for drinking water must through the processing or specific treatment.Tujuan penelitian ini adalah untuk mengetahui kualitas air berdasarkan beberapa parameter fisik, kimia dan biologi dari tiga sumber mata air, yaitu satu lokasi di kecamatan Kaliorang dan dua lokasi di Kecamatan Karangan.Karakteristik bentang alam di dua kecamatan hampir sama, yaitu merupakan perbukitan dengan torehan kecil. Begitu juga ketiga lokasi sumber air merupakan kawasan perbukitan Karst (Batu kapur). Bentang lahan Karst bukan hanya menyediakan bahan-bahan material, keanekaragaman hayati, tetapi juga penyedia jasa ekosistem seperti air bersih, pengatur tata air dan potensi atas dan bawah permukaan seperti gua-gua. Hasil penelitian menunjukkan bahwa kualitas fisik air dari ketiga sumber air memenuhi baku mutu yang dipersyaratkan. Dari hasil pengujian laboratorium, kualitas kimia air di tiga lokasi memiliki kandungan BOD (Biochemical Oxygen Demand)  dan COD (Chemical Oxygen Demand) yang relatif tinggi. Tingginya nilai BOD dan COD mengindikasikan bahwa air tersebutt dalam kondisi tercemar oleh akumulasi bahan organik terutama seresah dari vegetasi hutan diatasnya. Selanjutnya untukTotal coliform dan Fecal coliform walaupun jumlahnya di bawah ambang batas baku mutu yang dipersyaratkan, namun keberadaaannya di dalam air menunjukkan adanya kontaminasi sumber mata air oleh limbah seperti dari limpasan pertanian, kotoran hewan yang mengandung bakteri, virus, dan atau organisme penyebab penyakit lainnya. Berdasarkan kelas peruntukkan air, sumber air di ketiga lokasi sangat sesuai untuk digunakan sebagai irigasi, sarana atau prasarana budidaya ikan air tawar, rekreasi, dan peruntukkan lainnya yang mempersyaratkan baku mutu yang sama. Sedangkan untuk peruntukkan air sebagai bahan baku air minum terlebih dahulu harus melalui pengolahan atau treatment tertentu.

The occurrence and distribution of microcystins were investigated in Lake Taihu, the third largest lake in China. An extensive survey, larger and broader in scale than previous studies, was conducted in summer 2010. The highest microcystin concentration was found at southern part of Taihu, which was newly included in this survey. In northern coastal areas, total cellular concentrations of 20 to 44 μg/L were observed. In northern offshore waters, levels were up to 4.8 μg/L. Microcystin occurrence was highly correlated with chemical oxygen demand, turbidity, and chlorophyll-a. Extracellular/total cellular microcystin (E/T) ratios were calculated and compared to other water quality parameters. A higher correlation was found using E/T ratios than original microcystin values. These results show that algal blooms are having a severe impact on Lake Taihu, and further and extensive monitoring and research are required to suppress blooms effectively.

Rivers as surface water in Malaysia are recipients of effluents and wastewater and yet it is important water source for daily uses of some villagers living along the river. Endocrine disruptors such as Bisphenol A (BPA) can be found in river due to continuous discharge into it. The objectives of this research is to find out the occurrence and concentration of BPA in Sungai Langat and also to see how water quality parameters such as temperature, pH, dissolved oxygen (DO ), turbidity, Total Suspended Solid (TSS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and ammonia nitrogen (AN) affecting the concentration of BPA. 12 stations in total including upstream to downstream of Sungai Langat and also tributary of Sungai Langat. The instrument used to find out concentration of BPA is Triple Quadrupole LC/MS. The source of BPA are mainly industrial effluents and also direct domestic discharges. The water quality parameters that will affect concentration of BPA are Ammonia Nitrogen (AN), turbidity, Biochemical Oxygen Demand (BOD), Total Suspended Solid (TSS), and Chemical Oxygen Demand (COD), Dissolved Oxygen (DO). While pH and water temperature are also factors that will affect concentration of BPA but the significance is not shown in the analysis. It can be concluded that u pstream of Sungai Langat has lower concentration of BPA than downstream.

Water quality in the downstream river of a hydroelectric dam may be affected by the structural design and operation. To date, little is known about the water quality downstream of the largest dam in Malaysia, the Bakun hydroelectric dam. Therefore, the objective of the study was to determine the water quality downstream of the dam when the spillway was closed and when it was opened. Results of the study indicate that the dam plays a significant role in regulating the water quality downstream of it. When the spillway was closed, pH and oxygen were lower in the river where DO was below 5 mg/L. When the spillway was opened, the water quality improved in terms of oxygen content (>8.0 mg/L), total sulphide (TS), and chemical oxygen demand (COD) but deteriorated in terms of five-day biochemical oxygen demand (BOD5), total ammonia nitrogen (TAN), and total phosphorus (TP). Additionally, the intensity of the impacts, particularly BOD5, COD, and TAN, shows a declining trend as distance from the dam increases. This study shows that impacts on the water quality extend to a distance of 32 km from the dam particularly turbidity and DO and opening the spillway changes the water quality significantly.

This paper quantifies the biochemical oxygen demand (BOD), nitrogen (N), phosphorus (P) and navigational carrying capacities of Bengoh Reservoir for potential fish cage culture and recreational developments. The pollutant degradation coefficients (k) and pollutant carrying capacities (tons/day) of the reservoir were determined. The computed pollutant degradation coefficients were primarily based on the hydrological information of the catchment, hydraulic and operational details of the dam, and the targeted water quality standards of the river-connected Bengoh Reservoir. The maximum allowable pollutant loading rate (tons/year) defines the reservoir’s maximum Waste Assimilative Capacity (WAC) on specific pollutants (BOD, N and P), while in compliance to the targeted benchmark with the receivable pollutant loadings. It was found that the current BOD, TN and TP loading rates are 0.308 ton/day, 0.119 ton/day and 0.114 ton/day, respectively. To comply with Class I Standards of the National Water Quality Standards of Malaysia (NWQSM), the Maximum Allowable Loading Rates of BOD can be as high as 92.24 tons/day as compared to the current loading rate of 0.308 ton/day, maximum TN loading of 116.63 tons/day versus current 0.119 ton/day, and maximum TP loading at 125.54 tons/day versus current 0.114 ton/day. It was also found that the maximum number 218 cages (225 fish/cage) of Tilapia would be allowed in Bengoh Reservoir so as to comply with Class I of NWQSM. Based on the peak level of the reservoir recreational types of use in demand and the mix of public and private access, the navigational carrying capacity of the reservoir was estimated to be about 130 boats.
