Assessment of the Takla Landing contour trench wastewater disposal system / NovaTec Consultants Inc. : NH18-1/370-1989E-PDF
"A two year monitoring study of a community contour trench wastewater disposal system was carried out at Takla Landing B.C. The principal objective of the study was evaluate the effect of the following three trench bottom surface infiltrative media with regard to their ability of enhancing the formation of a biomat, or biological/organic material layer. The three media were: synthetic geotextile; the insitu material (a moderate to highly permeable sand/gravel); and a specified sand. Wastewater samples were collected using sampling devices located directly underneath the trench bottom and analyzed for BOD/COD, nutrients and bacterial quality. In addition, groundwater samples were collected from monitoring wells positioned downslope of the test section of the contour trench and the analytical data compared with the background groundwater quality with respect to nutrient and bacterial concentrations. Biomat samples were collected and analyzed for microbial activity and subjected to scanning electron microscopy (SEM)"--Summary, p. [4]. of cov.
