    Avaliação da potabilidade de água bruta no município de Bandeirantes-PR

    Even if our planet is filled with water, the potable portion is very small in comparison to all existing water, besides an irregular distribution among the population, and suffering more and more degradation by man, due to industrialization, agriculture, for example. Several parameters are analyzed for this to be accomplished, and based on this, this work analyzed the physical, chemical and microbiological parameters of the treatment plant (ETA) of the municipality of Bandeirantes – PR at its six catchment points (Rio das Cinzas – RC, four points of the Guarani Aquifer – AG1, AG2, AG3 and AG4 and Poço Artesiano Sertãozinho – PAS), comparing the seasons of the year in three consecutive years. pH, turbidity, organic matter, color, heterotrophic bacteria, total and fecal coliforms were evaluated. The results demonstrated, for example, that the RC point presented pH close to neutrality, while in the PAS point it had a range of 6.9 to 8.0 and in the aquifers values with higher pH between 8.0 and 9.6, that is, also higher in comparison to the RC point. Alkalinity was higher in the aquifers with intervals of 75–163 mg/L CaCO₃ between them, and PAS ranged from 109–130 mg/L CaCO₃ compared to RC, which had values of 46–55 mg/L CaCO₃, which is related to the higher pH and the high alkalinity of the aquifers. In the same way, dissolved oxygen with values at the RC point obtained higher values ranging from 5.45–16.2 mg/L, while in aquifers AG1, AG2, AG3 and AG4 obtained smaller values with intervals between 0.56–8.50 mg/L, and PAS ranged from 4.39–14.9 mg/L, due to the depth and high temperatures of these sites. In addition, data from the analysis of pesticides in water proved to be satisfactory under the legislation. It is concluded with this study that the RC point needs a more complex treatment for its use destined to the consumption of the population of the municipality in question.

    Potencial poluidor de cemitério

    Cemeteries are potential sources of enviromental impacts, principally for the risk of contamination of groundwater and surface water by microorganisms proliferate during decomposition process of bodies and chemical substances released. Contamined water may be used by neighborhood population. Major contaminant from cemiteries is leachate. With the objective to evaluate pollution potential of municipal cemetery of Bandeirantes/PR in groundwater and soil, samples wells were drilled in cemetery area and in an external area 30 meters away. Soil samples were collected during the samples wells drilling in three differents depths and water for analysis. Water samples were evaluated in SAAE laboratory in Bandeirantes/PR, according to the water potability standarts from ordinance 2.914/2011 of Ministery of Health and soil samples were sent to the soil laboratory to quantify heavy metal levels. Water samples had microbiological parameters above potability standards and soil samples had copper, chrome and nickel values above the references standards in differents depths.
