Estimation of Susceptibility to the Contamination of the Serra Geral Aquifer System in Aratiba-RS by Different Methods
The water supply in urban and rural areas is a problem faced by many countries. In southern Brazil, the Brazilian Southern Plateau, the city of Aratiba, is the reality of the small towns of the Rio Grande do Sul state, where both areas are supplied almost entirely by groundwater.

| description | The water supply in urban and rural areas is a problem faced by many countries. In southern Brazil, the Brazilian Southern Plateau, the city of Aratiba, is the reality of the small towns of the Rio Grande do Sul state, where both areas are supplied almost entirely by groundwater. This region presents some problems that threaten the quality of their groundwater, such as wastewater discharge waste from pigs and broilers without treatment, and the indiscriminate use of agrochemicals. In this context, this study aimed to estimate the susceptibility of the Serra Geral Aquifer System at the municipal level, through the Susceptibility Index and Groundwater hydraulic confinement, Overlaying Strata, Deph to groundwater table. For this we used information on land use, groundwater depth, aquifer material, recharge and topography. The results showed that the Aquifer System Serra Geral an IS ranging from low (27,09% of the municipal area) to high (2,29% of the area), with a predominance of moderate class low (47,24%). But the GOD system showed a vulnerability ranging from insignificant (13,54%) average (86,46%), with predominance of the middle class of vulnerability. The results for both methods were similar, indicating that the aquifer has natural conditions of protection due to the presence of volcanic rocks. However, the importance of environmental preservation is emphasized, either locally or regionally, thus reducing the risks of impacts to the environment, whether underground or surface. |

O abastecimento de água em zonas urbanas e rurais é um problema enfrentado por diversos países. No sul do Brasil, a cidade de Aratiba, representa a realidade dos municípios de pequeno porte do estado do Rio Grande do Sul, em que são abastecidos, quase por completo, por águas subterrâneas. Esta região apresenta alguns problemas que ameaçam a qualidade de suas águas subterrâneas, como o lançamento de efluentes dejetos de suínos e aves de corte sem tratamento, e o uso indiscriminado de agroquímicos. Neste contexto, essa pesquisa teve por objetivo estimar a susceptibilidade do Sistema Aquífero Serra Geral em escala municipal, por meio dos métodos do Índice de Susceptibilidade e Groundwater hydraulic confinement, Overlaying Strata e Deph to groundwater table. Para isso foram utilizadas informações do uso do solo, profundidade da água subterrânea, material do meio aquífero, recarga e topografia. Os resultados apresentaram que o município, tem um IS variando de baixa (27,09% da área municipal) a elevada (2,29 % da área), com predomínio da classe moderada a baixa (47,24 %). Já o método GOD demostrou uma vulnerabilidade variando de insignificante (13,54 %) a média (86,46 %). As metodologias aplicadas apresentaram resultados semelhantes, indicando que o aquífero apresenta condições naturais de proteção, devido a presença de rochas vulcânicas. Contudo, ressalta-se a importância da preservação ambiental, seja em escala local e/ou regional, assim reduzindo os riscos de impactos ao meio, seja ele subterrâneo ou superficial.
