Abstract
The study on private waste disposal systems (septic tank-tile fields, cesspools, etc) was carried out as a part of the efforts of Activity 3 in the Canadian Task C investigations under the IJC/PLUARG Program(International Joint Commission/ Pollution From Land Use Activities Reference Group). This study consisted of two parts: (I) field investigations of some existing private waste disposal systems, and (II) estimation of pollutant loadings from systems in watersheds adjacent to the Great Lakes. This report covers the part on field investigations. The objectives of the field investigations were: (i) to study the quality of the ground water adjacent to private waste disposal systems. (ii) to estimate the attenuation of chemical pollutants by various soils, and (iii) on the basis of the findings obtained in the field, to review the guidelines set by the Ontario Ministry of the Environment pertaining to the design and construction of septic tank-tile field systems.
