Land Application of Wastes: An Educational Program. Pathogens - Module 9.
Clarkson, W. W.; And Others
This module is intended to help engineers evaluate the relative health risks from pathogens at land treatment sites versus conventional waste treatment systems. Among the topics considered are the following: (1) the relationship between survival time of pathogens and the chance of disease transmission to humans; (2) the factors that favor survival of pathogens in the soil; (3) survival of pathogens on vegetation; (4) factors which affect the movement of pathogens through the soil and their uptake and retention on soil particles; (5) the possibility of pathogens moving to the groundwater and how long they live in groundwater; (6) the risks of crop contamination and how to minimize them; (7) the effects of various conventional treatment processes on pathogen removal; (8) factors that affect efficiency of chlorination on pathogen removal; (9) ways to minimize disease risks to animals grazing on wastewater-irrigated pasture; (10) insect control at the land site; (11) specific pathogens contained in wastewater; (12) infective doses; and (13) ways to reduce pathogens in aerosols.
