Article Synopsis
- The study employed multivariate statistical techniques, specifically cluster analysis (CA) and principal component analysis (PCA), to assess variations in water quality and contamination sources in an aquifer fed by the Trussu River in Ceará, Brazil.
- Groundwater samples from four shallow wells were collected over a period from October 2002 to February 2004 and analyzed for 13 water quality parameters.
- Cluster analysis revealed two distinct zones related to geographic and temporal differences, with the upland region influenced by agricultural activities and the downland region affected by human settlements, while PCA identified key factors affecting water quality in each zone, primarily linked to natural processes and anthropogenic impacts.
