Emerging organic contaminants in aquifers: Sources, transport, fate, and attenuation

Abstract

In this chapter we take a look at the presence of emerging organic compounds (EOCs) in groundwater, with emphasis in sources of pollution, processes affecting the spatial and temporal concentration of these compounds as they move through the aquifer and interact with the soil. Emphasis is placed on the combination of transport mechanisms and physical and biogeochemical processes that combine for natural attenuation and the potential eventual output to the biosphere. Some considerations about risks associated to the presence of such substances are also included.
