Nutrient Transport in Relation to Redox Transitions Below a Septic System Tile-Bed and in a Sand Aquifer

Abstract

Geochemical and mineralogical measurements were made at a high-capacity tile bed servicing Point Pelee National Park (PPNP). The analyses focus on the transitional redox zone directly below the tile lines and on nutrient transport in relation to changing redox conditions in the groundwater zone. The understanding gained from this study assists in the development of improved wastewater disposal systems and quantifying rates of nutrient loading into surface water bodies.
