Hydrogeochemical Characterization

This paper presents a comparative hydrogeochemical characterization on the predominant ions of the underground water that flow the Cocal vein, in the Mina 3 (Companhia Nitroquímica Brasileira), Fluorine Distritic of Santa Catarina, Morro da Fumaça Co., Santa Catarina, Brazil. Four samples were selected: P1 – underground water to 300 m of depth; P2 –underground water to 150 m of depth; P3 – water of the dam of reject; P4 – treated water of provisioning of Companhia Catarinense de Águas e Saneamento (CASAN). In the water sample collected in the selected sources, quantitative determinations of physical-chemical parameters (pH and electric conductivity) and of cations (Al, Ca, Cl, Li, Mg, Mn, K, Si, Na, and Zn) and anions (sulfate, chloride, bicarbonate, and fluorine) were performed. The results obtained revealed that most of the analyzed ions are related to the representatives that originated from rocks that constitute the pools where the studied water flow. The hydrogeochemical classification was obtained starting from the miliequivalence pattern among the main elements, in the cations and anions form being used the triangular diagram of Piper. The underground water of the point 1 presented a hydrogeochemical characterization compatible with is geological environment occurrence and being perceptible the characterization of an interrelation among the rock and the water that circulate within and they also presented an amount of larger ions than the water of the point 2, in since it flow through a mineralized pool. The underground water of the point 2 presented good potable conditions, with some restrictions. In the water of the point 3 there is a larger ions concentration by due to the washing of the mineral, that allows a larger solubilization of the elements, and the time of permanence of the water in the lake also causes larges concentration. The water collected in P4 point exhibit good water potability parameters and absence of conditions that favor fluorosis.

The present study is about the analysis of sullage collected from Tiruvanchery region, Chennai, Tamil Nadu, India. Sullage is the waste water from households, sinks, bathrooms, kitchen households but except the waste water from toilets. In this project, 6 samples of waste water were collected in 3 different apartments. The apartments are Ruby Grand, Ruby Regency and Green Paradise. The 2 samples of the waste water are the kitchen waste water and washing clothes waste water. Physical, chemical and biological parameters are tested in environmental laboratory. The chemical parameters were tested using titrimetric method. It is found that all samples were safe against pH, Alkalinity, Flouride, Chloride, Iron, Phosphate, and Turbidity which are within the permissible limits of IS3306 (1974)

The physical-chemical parameters characterization of Mindu Reservoir, whose 50% of its waters is being plagued byaquatic weeds, involved the analyses of water and sediment samples that were collected during the dry season. As thenutrients levels of Mindu waters were determined, phosphorous (TP - PO 43- ) levels were found to be high enough forsupporting eutrophication process. Likewise Nitrogen/Phosphorous ratios average of 8.51 ± 4.32 suggested a Redfieldbehavior of nutrients with nitrogen being a limiting one. The dominant clay minerals of the Mindu surficial sedimentswere found to be kaolin and illite, where as the Cation Exchange Capacity values were found to be high enough for thesorption of nutrients and pollutants. Both river inflows, overlay-flows and sediments forms the mode of transport ofnutrient, with the later behaving as sinks of nutrients through out the year. The evaporation, bio-geo-chemical andNitrogen fixation processes along with macrophyte productivity, support the hypotheses that physical-bio-geo-chemicalprocesses influences the spatial distribution of major ion in the Mindu Reservoir. These findings classify Mindu aseutrophic, calcium magnesium bicarbonate type. A detailed multidisciplinary study that involves more than one yearcycle was recommended, to capture inter seasonal variability, and for the modeling of the sequestration of nutrients invarious trophic levels.

The objective of this study was to characterize, through the physical-chemical parameters: pH, density, refractive index, moisture, total acidity, electrical conductivity, Lund test and ash, 20 honey bee samples from some municipalities in the State of Roraima : Cantá, Caroebe, São Luís do Anauá, Pacaraima and Vila Moderna. The results showed that 45% of the total samples studied presented values of moisture and acidity above the limits established by the standards. It is known that these parameters are related to the degree of maturity, processing, conditions of storage, adulteration and freshness of these honeys. As for the 55% of the remaining samples, these presented results within the limits established by the Brazilian standards, however, it is necessary to determine the other parameters required by the legislation to infer about the quality of the honeys produced and marketed in Roraima. In general, the results obtained present new information on the parameters that define the honey quality of bees in the State of Roraima.

In a more and more regulated and socially pressured environment, the durable management of winery effluents must take into account their characteristics and their potential impact on their natural setting. The object of this exploratory study is to establish an inventory of the microbiological composition of winery effluents coming from different treatment systems. We have observed that winery effluents are charged with micro-organisms, by a factor that ranges from 105 to 108 UFC/ml, and that the level of "microbiological pollution" is independent of the type of system. The composition of the flora is closely tied to the time of year and therefore to winery activities, so certain micro-organisms will be favoured in certain periods and others will have a tendency to decrease. We have seen that from one year to another our observations remain identical; the flora equilibrium therefore occurs systematically and naturally. Faecal germs are found in very small quantities in winery effluent treatment systems. They represent minor sanitary risks. Good correlations were observed between some micro-organisms and some physical-chemical parameters (COD). It is, however, difficult to use these "easy-to-measure" parameters as reliable markers of certain microbial populations.
