The use of wells to obtain underground water resources has become a complementary alternative for human supply. However, over the years, high consumption and anthropic action have contributed to the scarcity of groundwater and its contamination, have contributed to the contamination of groundwater, making it an agent that transmits diseases caused by pathogenic microorganisms from percolation of domestic sewage and/or chemical matter in concentrations that exceed the standards authorized by the Ministry of Health and CONAMA 357/2005, of the Ministry of the Environment. The aim of this study was to analyze the physical-chemical parameters: pH, dissolved oxygen, electrical conductivity, total dissolved solids, salinity, color and turbidity and to evaluate water quality by the Most Likely Number (NMP.100 mL-1) of total coliforms and thermotolerant, based on current legislations. In −1 total, 120 samples were analyzed for physical-chemical characterization and 6 for microbiological, from three wells in the community of Itapuama, located in the city of Cabo de Santo Agostinho - PE. Of the evaluated wells, two did not comply with the quality standard established by Brazilian legislation. The results showed a high concentration of electrical conductivity, low dissolved oxygen and high levels of microbial contamination. These non-conformities can originate from the inefficiency of the neighborhood's sewage system. The third well, since it is a phreatic tubular well, presented good quality water in the studied parameters, being above the limit only in the electrical conductivity parameter.

The use of groundwater is quite widespread in Brazil. Through artesian wells it is possible to find a regular and economically viable supply alternative. However, these waters are not inert to human actions, since in many studies pathogenic agents were found in these water bodies. The objective of this study was to correlate the quality of water from artesian wells to the socioeconomic profile of the population in the community of Itapuama, Cabo de Santo Agostinho, Pernambuco. To evaluate the water quality, seven shallow and deep water wells named A, B, C, D, E, F and G were selected, according to the probable susceptibility to contamination. Physicochemical analyzes of pH, electrical conductivity, dissolved oxygen, colorimetry, salinity, total solids, turbidity were carried out and for the microbiological analyzes were total and thermotolerant coliforms. The assessment of the socioeconomic profile was carried out with relevant public and non-governmental bodies in the municipality. In these meetings, parameters of occupation, family income, education level and selective garbage collection were analyzed. The results showed a direct correlation between the water quality and the socioeconomic factors of the sub-regions of the community of Itapuama, being evidenced in the Map of water quality x socioeconomic profile.
