Control of Odors from Construction and Demolition Debris
Landfills
Project Description:
Construction and demolition (C&D) debris landfills sometimes
experience odor problems as a result of reduced sulfur compounds
produced in the landfill. The most notable reduced sulfur
compound is hydrogen sulfide (H2S). The
production of H2S and other reduced sulfur compounds
has been linked to the disposal of gypsum wall-board. Previous
research efforts have explored the occurrence of H2S
at C&D debris landfills and in simulated laboratory
experiments. Recent laboratory work has also examined the
use of different types of cover soil to "filter" H2S
from the gas before it leaves the landfill. This project
expands this research to the field. The emissions of H2S
from actual C&D debris landfills will be measured using a
flux chamber. At one field site, different cover soil
types will be used to assess the ability of various materials to
attenuate H2S emissions.
Project Status:
The final report is currently being drafted.
All of the field flux measurements at the multiple sites have
been completed. Work continues on the field plot
monitoring.
