Resumo: | Water resources are essential elements for life and environmental modifiers processes, therefore be aware of the current situation can ensure efficient management that makes possible a more sustained use. Groundwaters have a great importance for the development of human activities. They play a crucial role in supplying the cities and as well as in the private sector, with the most different uses, both in urban centers and rural communities, as well as in private residential autonomous systems, industries, services, agricultural irrigation and recreation. This study aimed to the analysis of groundwater quality distributed to the population of the urban area of Mossoro-RN. The samples were collected in 16 active wells that are part of the water supply system in the urban area of the city of Mossoro and the analyzes were performed in the quality lab of water of Rio Grande do Norte's Water and Sewerage Company – CAERN in Natal city. The wells with lower dynamic levels are the PT - 02 PT - 23 PT - 20. These are located on the left riverbank and have previous drilling dates to 1980, since the wells with higher turbidity values were PT - 8 PT - 11 and PT - 14. We found a very strong and positive correlation between the EC with chloride, sulphates and STD. All the values found in the physical-chemical analyzes of water from 16 wells were below the maximum allowed by Ordinance No. 2,194 / 2011 of the Health Ministry classified as suitable for human consumption. The aid of geotechnology facilitated in data interpretation to show quickly the spatial variables through interpolation and maps, and may help in decision making. A Geographic Information System – GIS can improve the interpretation of the analyzes behavior of water quality in wells, in addition to decreasing the time spent and storage space, since the paper sheets would be replaced by a database |
