How Not to Design and Regulate Onlot Residential Sewage Systems - Someone Might Be Paying Attention

James A. Schmid

Schmid & Co. Inc., Consulting Ecologists

Abstract:  Onlot septic tanks with drainfields are common in Pennsylvania (1.2 million in 1990; 25% of homes) and nationwide.  More than a century of experience proves that they often treat domestic sewage effectively, with little maintenance and no moving parts or expenditure of energy.  But we now know that they seldom reduce nitrogen wastes sufficiently to protect our streams and estuaries.

James A. Schmid is a biogeographer and plant ecologist.  Before he finished his Ph. D. at the University of Chicago, he was asked to teach ecology and environmental science in the Department of Biological Sciences at Columbia.  After several years of teaching he unexpectedly took a job in environmental consulting.  For a year he ran an office in Manhattan for the late Jack McCormick, working on the NJ Sports Complex and Hartz Mountain development in the Hackensack Meadowlands and Fire Island National Seashore for the National Park Service.  Then he moved into McCormick's main office in Devon, where he became his vice president.  

For 35 years he has had his own firm focused on wetlands, environmental impact statements, and regulatory analysis. Examples of his work can be found at
