The efficiency of a peat biofilter treatment system and the impacts on groundwater quality

This paper describes the performance of the peat biofilter system in Virginia from July of 1997 to January of 1998. The performance of the systems has been monitored by the Civil and Environmental Engineering Department of Old Dominion University in accordance with the guidelines recommended by the Virginia Department of Health. The monitoring results from 123 systems installed in four different soil types operating under various climatic conditions are discussed. The effects of the systems on the groundwater in the various soil types are documented.
