Considerações hidroquímicas da água de poços que exploram o Sistema Aquífero Serra Geral (SASG) na região de Londrina-Pr

Abstract

Groundwater from the aquifers in the State of Parana are considered a major source of human and supply for other purposes being the interest in maintaining the quality the focus of the main basin committees and the general public. Groundwater is a right of fundamental importance to life, constituting one of the largest reserves of fresh water available on the planet. These reservoirs formed from rainwater through fissures, and areas of infiltration by outcrops of rocks. 41 samples were selected from Londrina-PR and region, containing all the data necessary for plotting anions and cation in the program Qualigraf and generation of diagrams of Piper, Stiff and the Ionic Balance. These analyses allowed the hydrochemistry classification of waters of SASG as the wells surveyed in the study area. Such characterization was based on results of chemical analyses of water wells in the study area raised using the Groundwater information system (SIAGAS). In these diagrams have been identified that the waters are predominantly Carbonated Calcium or Magnesianas, followed by a few points located in the classification of Sulfated Waters or Bicarbonated with sodium. And adverse points classified as Sulphated Calcic. It also showed high concentrations of chlorides and calcium carbonates.
