The chemistry composition of underground water is a reflection of the means where it percolates, being influenced by the types of drained rocks and also by adjacent human activities. The exploitation of these resources should follow the norms in force in order to provide drinking water and meet population demand. The reality faced by Fe em Deus community, located in Presidente Figueiredo City/AM, is the need to a plan for monitoring the subsurface water quality available to the population. The sampling plan consisted in periodic collection of wells output following the region seasonal cycle, analysis on situ and laboratory of physical and chemical parameters. The results were compared with published data about the chemical composition of the study area soil. For systematization and analysis of monitoring data, some tools of descriptive statistics were applied and checked for compliance with the limits established by current legislation.
