Evaluation of saprolite for on-site wastewater disposal

Technical Report ·
OSTI ID:6182263
Approximately 55% of the land in North Carolina is located in the Piedmont and Mountain regions, and over 50% of the people living in the state rely on on-site wastewater disposal systems for management of their household wastewater. A common characteristic of the soils in these two regions is the presence of saprolite at or near the surface. At present, certain saprolites are permitted for installation of septic systems. The rules and regulations for the use of saprolite for septic systems, however, are based less on scientific knowledge and more on the personal experience of those involved with the use of septic systems for on-site management of wastewater. A comprehensive study was undertaken to assess various physical, chemical, and morphological properties of twelve different soils and saprolites; and to study the performance of five septic systems in the Piedmont and Mountain regions of the state.
