Laboratory Testing Of Select Geotextiles As Biointrusion Barriers And Sediment Filters, David R. Beck
Laboratory Testing Of Select Geotextiles As Biointrusion Barriers And Sediment Filters, David R. Beck
Masters Theses
It has been proposed that placing a geotextile over sediments with adsorbed contaminants can prevent bioaccumulation of the contaminants in larger animals by isolating the benthic organisms living within these sediments from fish. In conjunction with a field study carried out at Gull Creek, a laboratory study testing two geotextiles as biointrusion barriers and sediment filters was conducted.
Constant-head permeameters were run for seven days using cores from the field study area with a geotextile placed over the cores. For biointrusion barrier tests, medium sand was placed over the geotextile and spiked with nutrients. Following each trial, benthic organisms in …
