Impactos sobre a qualidade da água nas imediações dos cemitérios municipais de Francisco Beltrão - PR

Abstract

The cemeteries are potentially causing enterprises of impacts to the environment and to the public health. In this context, the present report has the objective to verify the existence of impacts on the water quality in the urban area, on the surroundings of Padre Artur Vangeel cemetery and of the Municipal Airport Cemetery, and in the countryside area, on the proximities of the cemetery Km 8, located in the community with the same name, all in the city of Francisco Beltrão, Paraná. By visiting the studied cemeteries, it was done the collect of geographical coordinates to the map confection of the location of the cemeteries. In the water source of the community and in the Lonqador River were done analysis of the electrical conductivity, turbidity, calcium, hardness, ammoniacal nitrogen, nitrate, nitrite, and pH parameters, besides the microbiological indicators, total coliforms, Escherichia Coli and Clostridium perfingens, being that the first two were not done in the Lonqueador River sample. Besides that, information about the cemeteries were collected by questionnaires applied to the Municipal City hall of Francisco Beltão Sector of Urbanism and one inhabitant of the community Km 8, that indicated unknowledge by the city hall and the community about the existence of pertinent legislations to the cemeteries and its adequations. The characterization of the soil analysis indicated high contents of silte, showing density and porosity values that suggest soils with the capacity of retention of the contaminants. The water sample results of community Km 8 were compared to the maximum allowed values by the ordinance nº 2914 of the Health ministry (Brazil, 2011), while the water of the Lonqueador River were compared to the CONAMA nº 357 resolution (Brazil, 2008), according to the established for sweet water class II. The obtained results to the physical-chemical parameters proposed showed being within the established with the legal parameter of comparison for both samples, except ammoniacal nitrogen. The results obtained to the microbiological indicators showed not being in accordance with the comparing parameters. Although they do not make reference to the Clostriduim perfingens, this was evidenced in the samples. On the results, we can conclude that the studied areas have some remote contamination source, not being able to claim that it is coming from the cemeterial activity.
