Another great day in the Valley – the Killbuck Valley. After examining soils cores at the no-till field the group migrated to the South Wellfield for the rundown on the Wooster water supply.

Starting out at the OARDC after a brief encounter with a glacial erratic, we moved on to the Secrest Arboretum to appreciate the history of growing trees there and the ongoing experiments (including the Triplett-Van Doren no-till experiment.

Next at the South Wellfield – the family of wells included, water supply, monitoring and interceptor wells.

Professor Current, who is a contaminant hydrogeologist, fills us in the evolution of a contaminant plume.

Air stripper tower – one good way to remove VOCs.
