The purpose of this student-led research was to evaluate the use of subsurface wetlands constructed with an organic medium for the denitrification of domestic wastewater. Nitrate removal performance and the effects of concentration, temperature, length of operation, and aquatic plants were assessed. Six different subsurface wetlands were constructed to study the effect that media type, time of operation, and aquatic plants have on the removal of nitrate.
