Influência dos níveis de serviço de saneamento para a qualidade de água de poços rasos residenciais nos bairros 5º congresso e Alto macassa na vila sede de Vilankulo

Abstract

The present work had as a general objective to evaluate the parameters of water quality water in residential wells in the neighborhoods 5th Congress and Alto Macassa, to obtain knowledge of the actual situation of the quality of water captured and the conditions of levels of sanitation service, subdivided by the specifics in which were, identify the levels of service levels of the households with wells, analyze the physical and organoleptic parameters organoleptic parameters (color, smell, conductivity, taste, pH and turbidity), microbiological (fecal coliforms and total coliforms), chemical (Iron, Copper, Manganese, Total Dissolved Solids and Solids and Dissolved Oxygen). Meanwhile, 40 shallow wells were qualitatively analyzed in the the town of Vilankulo precisely in the neighborhoods 5th Congress and Alto-Macassa (in which the same the same analyses were performed in two phases), for the microbiological analyses the used was the membrane filtration method for the determination of the Most Probable Number (MPN) (MPN), for the physical and chemical analyses direct measurements were made using specialized (pH meter, colorimeter, turbidimeter). In terms of sanitation service levels sanitation service levels, a survey was conducted with 40 households, 20 in each neighborhood, where purposive of the same was used non-probabilistic purposive sampling to obtain data and direct observation on site, where it was found that all residences have at least one latrine, in general in terms of latrine, in general in terms of provision of services can be said that most have limited sanitation services and the most common form of disposal of solid and liquid waste is liquid waste is direct disposal on the ground without treatment, which increases the risk of contamination the water since the location of most wells does not meet the standards of minimum distance between between latrines and gutters allied to the weak use of the practice of water treatment for However, the biggest problem lies in the water quality, where according to all water quality parameters water quality parameters analyzed only 5% of the sample in the 5th Congress District and 15% of the sample in the Alto-Macassa neighborhood have potable water, that is, they present all parameters within the potability standards.
