In the area constituted by the municipalities of Barbalha, Crato and Juazeiro do Norte, south of Ceará State, groundwater resources are the only source of public and private water supply, and overexploitation is already evident in the intermittency of the old perennial drainage network, now perpetuated by sewage launches. The chemical evolution of groundwater was studied by identifying of similarities between physicochemical variables, discriminating the most significant ones, through the methodology of multivariate statistical analysis to explain possible processes responsible for water quality in the area. The factorial analysis identified three components responsible for approximately 85% of the total variance; the first one as an indica...
