Sources and Source Pathways

To effectively minimize environmental contamination it is necessary to understand potential contaminant origins and pathways to the environment.

Emerging contaminants can originate from a variety of animal- and human-waste sources

Emerging contaminants can originate from a variety of animal- and human-waste sources. Pathways to the environment range from rapid and direct discharges of effluent into a water body to the slow leaching of stored waste through soils.

A myriad of sources of emerging contaminants and pathways to enter the environment exist throughout the world (see figure). Sources and Source Pathway research activities address: 1) identification and quantification of the contaminants or groups of contaminants associated with major sources and 2) processes that govern how these contaminants enter the environment (pathways). Research on sources and source pathways includes:

Emerging Chemical Contaminants

Emerging Microbial Contaminants
