Groundwater plays a key role in the maintenance of aquatic systems, in support of various economic activities, in addition to being used for human consumption. Due to the great use of water from wells in several cities of Ceará, the objective of the present work is to analyze some physico - chemical parameters based on CONAMA Resolution 396 of 2008 that is related to groundwater, verifying if that the waters of ten wells, chosen at random, located in the municipality of Piquet Carneiro - CE comply or not with the legislation in force for human consumption. Data were analyzed for the years 2014 and 2018, in the months of march and november, seeking to follow the variations of the results for the parameters under study. Chlorides, total hardness, nitrates, pH, total dissolved solids and turbidity were evaluated. The results of the samples showed for the chlorides, in general, much higher values in the months of november than in march. In relation to total hardness, the values under analysis followed a pattern very similar to the results of chlorides, where in november, except in a single well, the values were much higher than in the months of march. Nitrates, in both 2014 and 2018, presented quite varied results for the ten wells, without maintaining a standard as in the parameters mentioned above. For the pH, it presented small variations in the ten wells under study, always presenting values close to each other. For the total solids dissolved, in the majority of the wells, there were lower values in the month of march in relation to the month of november. Finally, the turbidity brought values well above that allowed for a single well in the year 2014, for the other wells, the results were fulfilled by the legislation. Still in relation to turbidity, in the year 2018, the same well with high values in the year 2014 continued presenting a high value in the month of march, reducing it in the month of november. With the presentation of the results, we observed that for the ten wells studied in this municipality, and taking into account only the analyzed parameters, it was verified according to the current legislation that the waters of the same are unfit for human consumption. At the same time it was not possible to establish a pattern of influence of rainfall for the results, since several other factors can alter the values of the parameters, such as anthropic activities, making a detailed study of the surroundings of the wells necessary.
