Pathogen and Pathogen Indicator Removal Characteristics in Treatment Wetlands Systems

Abstract

This paper reports the performance of two horizontal subsurface flow constructed wetland systems in the removal of pathogen and pathogen indicators under variable loading and operating conditions. The two constructed wetland systems evaluated under this project are located near Lincoln, Nebr. Firethorn is located in a small housing community and Rogers Farm at a rural single-family dwelling. Samples at Firethorn were collected at the wetland cell influent, effluent, and sand filter effluent (system effluent) from June 1996 through April 2000 and at the influent and effluent points from Rogers Farm from June 1999 through April 2000. The main monitoring parameters were fecal coliform at both sites and
