 Considering the current importance watercourses quality conservation, it is important to establish relationships between parameters that enable evaluation of the origins of changes in water quality, allowing actions to mitigate them. However, it is important to improve the association of different variables and to take sufficient samples. This study associates usual techniques and parameters to analyse the water quality of an urban river from Paraná State, Brazil. For this, we used biological indicators (aquatic macroinvertebrates), physical-chemical (temperature, turbidity, true colour, pH, DO and BOD5,20) indicators and microbiological (faecal and total coliforms) indicators. These indicators were related to land use and occupation classes obtained from high resolution QuickBird 2 images. For this association, the surroundings (450 meters buffer) of three distinct points of the river were considered: I. Near the spring; II. In the downtown city; and III. In a residential neighbourhood. Different values of physical, chemical and microbiological variables were detected along the river, showing evident relationships between them and with the use and occupation of the urban and peri-urban space in the characterization of surface waters. The association design was able to detect the landscape effect on water quality in a coherent way and that these connections were mainly related to suppression of the riparian forest present in the surroundings, further demonstrating the importance of this vegetation for the maintenance of watercourse quality.

The aim of this research was to study the ciliated protozoa community at three sampling stations that receive different levels of domestic sewage along the São Pedro Stream in the municipality of Juiz de Fora, Minas Gerais, Brazil, in order to determine the influence of organic pollution on this community and to assess the feasibility of using ciliates as water quality indicators. Four physical-chemical parameters of the water samples were evaluated: dissolved oxygen concentration, electrical conductivity, pH and temperature. The sediment was obtained manually, using dredges with capacity of 300 mL, at each collection point. Point 1 was located in a rural region that receives a low sewage load, while Points 2 and 3 were located in populated regions receiving high sewage loads. We found 22 ciliate species, of which 18 are included in the saprobic system and are considered bioindicators. These showed beta-mesosaprobic environments at Point 1 and alfa-mesosaprobic to polisaprobic environments at Points 2 and 3. The low levels of dissolved oxygen and the high electrical conductivity values at Points 2 and 3, together with the strong similarity between the ciliate taxocenoses of these points and the weak similarity between Point 1 and the other two, confirm the high sewage loads received at the latter two points. The combination of the biological indicators and physical-chemical analyses therefore proved itself to be an efficient method of evaluating water quality, and has excellent potential to support decisions on the conservation of headwaters and recuperation of degraded environments in lotic systems.

Measurements of DO indicate that in lake waters oxygen consumption is higher, whereas BOD5 results show that waters Situ Lebak Wangi already contaminated by organic material easily explained (BOD5). The electrical conductivity values range from 112.0 - 118.0 μhos / cm. The result of Situ Lebak Wangi water quality analysis as a whole shows that the water is not feasible to serve as raw water, because it contains Salmonella-Shigella pathogen bacteria which is the cause of thypus and cholera.</strong></p><p><strong> </strong></p><p><strong><em>Keywords</em></strong><strong> - </strong><em>physical quality, chemistry and biology, </em><em>Situ Lebak Wangi, </em><em>Waters, Water quality standards</em><strong><em></em></strong></p>

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

The aim of this work was to be traced during the summer and autumn of 2009 the level and dynamics of changes in the waters of the port the port Świnoujście general parameters pools water quality. In the work of the General indicators of water temperature, were numbered: pH, BOD5, COD-Cr, Cl-. All the markings and the calculation was performed according to the methods recommended by Polish Standards, applying analytical procedures described in. by Dojlido, Elbanowską, Hermanowicz. Port of Świnoujście is a sea port located on the Gulf of Pomorską, on the southern coast of the Baltic Sea, on the islands of Usedom and Wolin. The Port is located at the Świna, in Świnoujście, West Pomeranian Voivodeship. The port can be placed on ships with a maximum length of 42.0 m and width 260,0 m, draught 12.8 m. The tides in the Harbor, but the water level fluctuations are possible with sudden currents entering and outgoing, which depending on the direction of prevailing winds and reaching speeds of up to 1.5 knots. At the entrance to the port at the West breakwater, It is Western. The primary function of the port of Świnoujście is the transshipment of cereals, ores, oil, paper, cellulose, general cargo, coal, iron. Trying to test water were collected by PN/C-04632.03 with a depth of about. 2 m below the water surface. The temperature at the place of sampling were numbered, pH. Collected water samples were fixed in accordance with the recommendations in the Polish Standard-PN/C-04632.04. Other indicators for the quality of the waters have been tagged within 24 hours from the moment of download attempts. The quality objectives was evaluated according to the criteria recommended to evaluate inland surface waters referred to in regulation of the Minister of the environment of 11 February 2004 on the classification for the present status of surface water and groundwater, how to conduct monitoring and how to interpret the results and presentation of these waters. Due to the exposure of the docks the port Świnoujście on the pollution associated with cross-what are the cereals, ores, oil, cellulose, carbon, iron, general research evaluation of the water quality of these pools, you can assess the status of water in order to keep these waters.

Characterization of Environmentally friendly materials used as wastewater treatment material has been studied in order to compare the quality of wastewater in Chiang Mai, Thailand on two types of treatment materials, which are cow bone char (CBC) made from Thai cow bone char cleaned and calcined at 850๐C and the a mineral called “zeolite” (ZLT) bought from Kamthiang market, Chiang Mai. The physical characteristics of both types of materials indicate that the CBC has a higher density than the ZLT but has lower pore volume than the ZLT. The effect of density on the water quality improvement was showed that CBC was a suitable type of wastewater treatment material because their high density can fix them in the batch system.
