RESUMOO município de Crateús está localizado na região semiárida do Nordeste do Brasil, onde as condições climáticas provocam escassez hídrica e baixa qualidade nas águas disponíveis. Este trabalho teve por objetivo estudar, durante um ano, o comportamento do pH e das concentrações dos íons carbonato (CO 3 2-) e bicarbonato (HCO 3 -) nas águas de oito poços utilizadas para irrigação de pequenas culturas e consumo doméstico. Os resultados mostraram que nenhuma das amostras apresentou valor de pH que comprometesse sua qualidade, tanto para uso na irrigação, quanto para consumo humano. No entanto, os íons bicarbonato e carbonato apresentaram grau de restrição que varia de leve a severo. Portanto, seu uso na agricultura demanda monitoramento e cuidados rigorosos para amenizar os efeitos negativos na produtividade e no solo.Palavras-chave: parâmetros, poços amazonas, recursos hídricos, técnicas de manejo. Hydrochemistry of carbonate and bicarbonate: effect on groundwater quality in Crateús, Ceará, Brazil ABSTRACTThe city of Crateús is located in the semi-arid region of northeastern Brazil, where climatic conditions cause water scarcity and low quality of available water. This work was a one year study of the behavior of pH and concentrations of carbonate (CO 3 2-) and bicarbonate (HCO 3 -) ions in the waters of eight wells used for irrigation of small crops and domestic consumption. The results showed that none of the samples had pH values that compromised their quality, both for use in irrigation and for human consumption. However, carbonate and bicarbonate ions presented restrictions that varied from mild to severe. Therefore, its use in agriculture requires rigorous monitoring and care to mitigate the negative effects on productivity and soil.
