Tarahara Fish Farm includes 37 large ponds as a fish super zone. Physicochemical parameters viz., air and water temperature, pH, DO, BOD, CO2, Cl-, TA and TH of these ponds were studied for two years (Nov. 2008 to Oct. 2010). The air temperature had positive and significant correlation with water temperature (r=0.893, P<0.01) but inverse and significant correlation with DO (r = - 0.669 P<0.05) and TH (r = - 0.673, P<0.05). Both air and water temperature showed a decreasing trend during the winter months of November to January and again September to October in both years. Similarly, positive and significant correlation showed by pH with DO (r =0.660, P<0.05) and BOD (r =0.846, P<0.05); by free CO2 with DO (r=0.854, P<0.01), chloride (r=0.648, P<0.05) and TA (r=0.616, P<0.05); by DO with TA (r =0.715, P<0.01) and chloride (r =0.625, P<0.05) and by TH with TA (r= 0.592, P<0.05) but inverse and significant correlation showed by pH with water temperature (r =-0.671, P<0.05); by free CO2 with BOD (r=-0.627, P<0.05) and by DO with BOD (r = -0.810, P <0.01). The water quality parameters were within suitable range for the fish growth and breeding with small fluctuations in different months during the first and second years. Physico-chemical parameters significantly (P<0.01; 0.05) differed between different months. However, no mass mortality of fish was recorded from this site. So, the area selected as fish super zone is fruitful to meet the expected production level of fishes and fish seeds in peripheral areas.

This case study characterizes the drinking water quality by using the multivariate technique. The spatial variation of the physico-chemical and heavy metals parameters toxicity with the drinking water quality based on 28 water treatment plants in Selangor, Malaysia from 2009 to 2012 was evaluated. The objectives of this study are to analyze the physio-chemical activities and heavy metals activities in the collected drinking water samples from the treatment plants, and to detect the source of pollution for the most revealing parameters. The discriminant analysis (DA) and the principal component analysis (PCA) are the chemometric techniques used to investigate the spatial variation of the most significant physico-chemical and heavy metal parameters of the drinking water samples. The classification matrix accuracy for standard mode of DA, forward stepwise and backward stepwise for the physico-chemical and heavy metal parameters are excellent. PCA highlighted 13 significant parameters out of 18 physico-chemical water quality parameters and 14 significant parameters out of 16 heavy metal parameters. PCA was carried out to identify the origin and source of pollution of each water quality parameters. For that reason, this study proves that chemometric method is the principle way to explain the characteristic of the drinking water quality.

From the field observation it is apparent that the color of coal leached drainage water and the agricultural land water are blackish and slightly blackish respectively, which pollutes surface water and the agricultural land. The study showed the present status of the water quality through analyzing different parameters including color, temperature, pH, EC, DO, TDS, BOD, COD, Cl-, Cu, Zn and Fe as well as the status of soil quality where pH, OC, PO4 -, Cu, Cr and Zn were analyzed. All the water quality parameters (e.g. temperature, pH, EC, TDS, DO, and BOD) were within normal levels but the value of COD was higher, which affects the aquatic environment. The concentration of heavy metals in water varied with Zn > Cu > Cr and in soil the concentration varied with Cu > Cr > Zn.Bangladesh J. Sci. Res. 27(1): 63-73, June-2014

The wetlands located at the periphery of Jimma town, southwestern Ethiopia, have critical roles in providing a range of ecological and socio-economic benefits, yet they are subject to increasing anthropogenic disturbances, notably through agriculture, settlement, intensive grazing and brick-making. This study assessed the ecological status of these wetlands, and examined the scale of the human disturbances that local communities might impose on them. Macroinvertebrate communities, water quality parameters, and human disturbance scores were assessed. Except for electrical conductivity and water temperature, no significant difference (P < 0.05) was found in physico-chemical parameters between the sampled sites. Nitrate was the only parameter that correlated with significant influence on species richness of the sampled macroinvertebrates. A total of 10 metrics were used to generate the index of biotic integrity (IBI). This IBI was then tested based on macroinvertebrate data collected. Ways of assessing and evaluating the existing ecological status of the wetlands are discussed in the context of physico-chemical parameters, IBI based on macroinvertebrates and human disturbance scales.

Abstrak. Korosi atau kerusakan yang terjadi di infrastruktur sumber daya air terutama yang berbahan semen atau mortar dengan fc’ atau dengan nilai kuat tekan ≤ 30 Mpa, dapat menimbulkan banyak kerugian. Kerugian yang ditimbulkan antara lain kerugian secara materiil karena korosi menggerogoti semua aset infrastruktur dan tentunya kerugian dalam hal keamanan karena dapat mengancam keselamatan manusia. Korosi merupakan permasalahan yang sangat penting dan tidak akan ada habisnya, karena peristiwa korosi terjadi secara terus-menerus dan berkelanjutan. Peristiwa korosi tidak dapat terjadi dengan sendirinya, tetapi karena adanya berbagai faktor-faktor tertentu yang dapat menyebabkan terjadinya korosi. Tujuan dari studi ini adalah untuk menentukan tingkat korosivitas air terhadap infrastruktur sumber daya air berbahan semen atau mortar dengan fc’ atau dengan nilai kuat tekan ≤ 30 MPa pada 9 waduk di Indonesia, sehingga akan diketahui rekomendasi yang tepat untuk pencegahan dan pengendalian korosivitas air terhadap infrastruktur sumber daya air berbahan semen atau mortar dengan fc’ atau dengan nilai kuat tekan ≤ 30 MPa, karena semen merupakan salah satu material yang paling banyak digunakan saat ini. Studi ini menggunakan data-data primer kualitas air. Metode pengambilan, penyimpanan, dan pengawetan sampel air dilakukan dengan mengikuti ketentuan dari Standar Nasional Indonesia Nomor 6989.57:2008. Pengujian kualitas air dilakukan oleh laboratorium yang terakreditasi.

Hasil perhitungan LSI A, B, C, D, dan SI Standard Method APHA-AWWA-WEF menunjukkan bahwa tingkat korosivitas air di 9 waduk berpotensi menyebabkan korosi terhadap infrastruktur sumber daya air berbahan semen atau mortar dengan fc’ atau dengan nilai kuat tekan ≤ 30MPa. Kata kunci: infrastruktur sumber daya air, Langelier Saturation Index, Saturation Index, tingkat korosivitas air. Abstract. Water Corrosivity Level Againts the Water Resources Infrastructure Made of Cement or Mortar with fc' ≤ 30 MPa in 9 Reservoirs in Indonesia. Corrosion or damage that occurs in the infrastructure of water resources, especially those made of cement or mortar with fc' or with a compressive strength value of ≤ 30 MPa will be able to engender losses. Losses incurred, in the form of losses materially because of corrosion gnaw off all infrastructure assets and of course in losses terms of security, because it can threaten the safety of a human. Corrosion is a very important problem and will not be endless, as corrosion events occur continuously and sustainably. Corrosion events cannot occur by themselves, but because of certain factors that may cause corrosion. The purpose of this study is to determine the level of water corrosivity to the infrastructure of water resources made from cement or mortar with fc' or with a compressive strength value of ≤ 30 MPa in 9 reservoirs in Indonesia, to develop appropriate recommendations for the prevention and control of the water corrosivity to the infrastructure of water resources made from cement or mortar with fc' or with a compressive strength value of ≤ 30 MPa because cement is one of the most used materials today. This study uses water quality primary data. The methods of capturing, storing, and preserving water samples are carried out following the provisions of Indonesian national standard number 6989.57:2008. Water quality testing is done by accredited laboratories. The method of calculation uses the Langelier Saturation Index (LSI) A, B, C, D, and the formula Saturation Index (SI) of the Standard Method APHA-AWWA-WEF. Calculation results of LSI A, B, C, D, and SI Standard Method APHA-AWWA-WEF show that the level of water corrosivity in 9 reservoirs has the potential to cause corrosion of water resources infrastructure made of cement or mortar with fc' or with a compressive strength value of ≤ 30 MPa. Keywords: Langelier Saturation Index, Saturation Index, water corrosivity level, water resource infrastructure.

Physical, chemical, and biological parameters of the Kole (Open type) and Suguna (Closed type) wetlands have been investigated from January 2011 to December 2013. These lakes are locally called as Baur.The work has been carried out for one and half year period from nov 2011- May2013 in different seasons viz. monsoon, post monsoon and premonsoon respectively in order to assess water quality parameters and diversity of biotic communities. The present article attempts to investigate the possible interrelationship among the physicochemical parameters and biotic communities of both the beels. During the investigation, zooplankton diversity was observed high in the wetland. Rotifers were the most dominant group followed by Cladocera, Copepoda, Protozoa and Ostracoda during the investigation. There is a high density of zooplankton in monsoon than compare to other seasons indicate good water quality and less pollution load in both beels. These investigations will be the basic guidelines for the researcher in the field of ecology of beels. The comparison of the ecological parameters of these two lakes is attempted in the present investigation. The study aim to investigate the diversity of biotic communities in relation to physico-chemical parameters of surface water in gangetic plain. Physico-chemical parameters of both the beels revealed well marked fluctuations with maxima and minima values of each parameter during specific months and analysis of biotic communities revealed seasonal variations with an increase during summer and a fall during winter and monsoon seasons.
