Abstract
This investigation reports the results of a study realized in an area related to the
development of sand mining activities, which belongs to Sibelco Mineração Ltd.
The site is located around Analândia municipality, nearly in the center of São
Paulo State, Brazil. Hydrochemical analyses of groundwater were realized under
different periods of time, with the aim of evaluating the possibility of release of
several constituents to the liquid phase, which may be a source of pollution of
the surface hydrological resources and of the deeper Guarani aquifer. This is
because the site is located at the recharge area of Guarani aquifer and some
tributaries from Corumbataí river may also be suffering contamination, implying
on the impoverishment of the water quality that are very important resources in
the region, as they are extensively used for drinking purposes, among others.
Keywords: sand mining activities, water quality, groundwater, elemental
concentrations, trace and heavy metals, São Paulo State.
