The groundwaters generally present good quality because it is naturally filtered by
the porosity of the geological formations. It can reach the subsoil saturated zones
and be stored in aquifers. As water is a very reactive substance, while infiltrating the
soil it can dissolve constituents that are presented in geological formations, thus,
groundwater are often considered rich in minerals. Among other advantages, such
as good availability, the use of groundwater is an important alternative to sanitation
and water supply demands. In the city of Londrina – PR and its metropolitan area, it
is predominated the uptake of groundwater from the Serra Geral Aquifer System
(SGAS), followed by the Guarani Aquifer System (GAS), which is confined in the
area. In order to determine the hydrochemical pattern related to the ionic
compounds dissolved in the groundwater that supply the municipalities of Cambé,
Ibiporã, Londrina and Tamarana, a database of wells which capture water from the
SGAS and GAS, used to supply water for those municipalities, was created. From
the information obtained, it elaborated Piper and Stiff Diagrams, which allow the
hydrochemical classification of water. It was found that in the study area, the waters
are divided into classes ofcalcic/magnesian bicarbonate, characteristic of SGAS
waters and sodic bicarbonate characteristic of GAS water. It was verified that in the
study area, waters from wells of GAS presented characteristics from SGAS waters
and also the contrary, which may point interconnection of aquifers in the resulting
localities. After performing spatial analysis on the concentration of ionic compounds
that were predominant in the analysis, it was found that sodium concentration and
total alkalinity increased from South to North and from East to West, where there is
a higher level of containment, which is proportional to the dissolution and ion
exchange occurring in the aquifer. |
