Natural attenuation – a method for aquifers rehabilitation [articol]

Abstract

Contamination of soil and water by various forms of pollutants is a fact in this industrialized age. Pollutants threaten the health of biotic and environmental receptors so their effect should be minimized or even removed if possible. So far in Romania no one did detailed studies on natural attenuation. Therefore in this paper, we propose to present the phenomena occurring in this process. The natural attenuation process is very complex and includes transport processes of pollutants, degradation processes and reduction of contaminants in soil and aquifers. This paper aims at presenting natural attenuation phenomena and to highlighting the need for monitoring these processes.
