Impact of the ambient air quality due to the dispersion of non-methane organic compounds from Barka Landfill
Abdul-Wahab, S. A.; Hajri, A. Al- & Yetilmezsoy, K.
Abstract
This study used the CALPUFF modeling system
to study the impact of an area’s geophysical and
meteorological conditions on the dispersion of non-methane
organic compounds (NMOCs) into the atmosphere
from the 17-year-old Barka Landfill. Barka Landfill
is located in Barka, Batinah, in the north of the Sultanate of
Oman. It receives waste from nearby regions such as
Nakhal, Seeb, and Wadi Al-Maawel, affecting the town of
Barka with landfill gas (LFG) pollution. The present study
was conducted to evaluate the impact of the air dispersion
of one group of NMOC gases on Barka and the region
around it. The top five values of the concentrations with
different average time periods, namely 1, 3 and 23 h, were
compared with the allowable emission rate defined by the
US Environmental Protection Agency (EPA). The results
demonstrated that the present integrated modeling system
(consisting of a 3D diagnostic CALMET model and
Lagrangian puff dispersion CALPUFF model) could be
utilized as a useful tool for evaluating the top five peak
values of the NMOC emissions of the different time
periods.
