ANÁLISE FÍSICO-QUÍMICA DA ÁGUA DE TRÊS POÇOS SUBTERRÂNEOS DO MUNICÍPIO DE MOSSORÓ-RN

Resumo

Water is a key resource for life. But population growth combined with intensive and mismanagement have caused prejuiÌsos water quality, generating economic and environmental problems. One problem is the pollution of groundwater that focuses more on urban areas, where large volumes of pollution sources such as untreated sewage and garbage dumps for example. The city of Mossoro-RN located in the northeastern semi-arid region, located in western Rio Grande do Norte state, according to the IBGE Census 2010 has a population of 259. 886 inhabitants with 70% of its population supplied by water from underground wells. The consumption of water contaminated by biological or physical-chemical agents has been associated with various health problems. Therefore, the aim of this work was to analyze the groundwater samples collected in three different points of the city of Mossoro-RN and compare the values obtained at each point between themselves and with the legislation in force, evaluating their quality and the influences anthropogenic local these characteristics. The results showed that the water fall in class 3. Some characteristics such as dissolved solids, and sulfate nitrite meet the standards Conama No. 396/2008, others as nitrate and specifically the chloride of sample 2 shown above permitted values, showing that points 2 and 3 have a low sewage service and population density, which contributes to increasing pollution in these places.
