This project contemplates the groundwater studies in alluvial aquifer that deposits have records that show records of river dynamics, the subaquatic environment and the conditions of periodic floodings and aquifer recharge (through rain water or superficial waters). The present proposal aims to study groundwater of these alluvial plains, identifying typical characteristic features and understanding the subaquatic waters their interrelationships. The alluvial plain of the Atibaia river is in Barão Geraldo, peri urban portion of Campinas (SP), where there is still no basic sanitation network. The characteristics of hand dug wells, cesspool and their water quality impact will also be evaluated, in two different seasons. The pedological, sedimentological, hydrodynamical studies combined to hydrochemistry and isotope hydrology shall contribute to the better understanding of groundwater in alluvial plains as well as recharge and discharge conditions in shallow aquifers. The project includes the determination of the concentrations of rare earth elements dissolved in groundwater with the objective of increasing knowledge of the water-rock interactions and verify the presence of anthropic gadolinium, an emerging contaminant from the use as a contrast in diagnostic medicine. The investigation of the presence of drugs (omeprazole and metformin hydrochloride) aims to verify the influence of domestic sewage in the areas of in situ sanitation. The development of groundwater drug analysis method is unprecedented in the country and will contribute to the activities and processes that occur in groundwater and the relationships between hand dug wells and cesspool.
