Aspects of contamination produced by domestic waste landfills of receiving waters in Madrid province

Abstract

This study describes some aspects of the anion content in surface waters and ground waters as well as ín the soils affected by three landfills in the Province of Madrid. The anions concerned are chlorides, fluorides, sulfates, phosphates and nitrates. The pH and conductivity were also determíned. These parameters may constitute abiotic índicators to observe the alterations produced in the water and soil by the leachates from the landfills. The results show that the concentrations of the parameters analyzed increased considerably in some water and soil samples from the surroundings of the landfill. It is important to determine the effects of theses anions on the water and soil and to create predictable patterns in order to protect or restore them.
