Subsurface disposal of domestic septic effluent in a haploxeralf soil in Southwestern Oregon

Creator:

Silvernale, Alexandra

Abstract:

Experimental Drainfields: Standard subsurface sewage disposal systems, gravity loaded and 60 cm deep on slopes above 15% did not show signs of effluent surfacing after 14 months of operation. However, subsurface signs of failure were found on both the experimental sites and on older drainfields established in identical soils. Evidence...

A soil property model for evaluating pesticide movement potential

Creator:

Vogue, Margaret A.

Abstract:

Prevention of groundwater contamination by agricultural chemicals requires an understanding of the complex processes that control pesticide movement below the soil surface. Through this understanding it is possible to try to predict which areas may be most vulnerable to contamination. The many models that have been developed to characterize pesticide...
