163 Not for Export: Contaminant Issues In Agricultural Drainage: I

Oral Session
S11 Soils & Environmental Quality The continued expansion of agricultural drainage has strong implications for agricultural management to protect water quality. In this topical session, we will review recent developments to assess and reduce contaminant transport via drainage. The session will include discussion of changes in local hydrology effected by artificial drainage and the export of a variety of potential contaminants (nutrients, pathogens, pharmaceuticals, pesticides, salts, etc.) from agricultural land. Trade-offs and risks/benefits of agricultural drainage will be discussed. This session will be useful to those interested in reducing contaminant transport to improve water quality and preserve agricultural productivity.
