Week ending November 14, 2005
APAC/Reno continues to treat the lower (east) pond with sodium hydroxide and hydrogen
peroxide to control the hydrogen sulfide production.
APAC/Reno has ordered materials to construct the landfill gas wells and gas collection
system. The purpose of this system will be to trap the gases and incinerate them, so
they no longer are emitted into the atmosphere.
Based on the results of the preliminary hydrogeologic study mentioned in the
previous update, it was decided a more extensive hydrogeological study was needed.
APAC/Reno has submitted a revised work plan for the study. Well drilling may start
November 28. When wells are drilled, there may be transient hydrogen sulfide odors,
but the wells will be capped to limit odor release during the project.
APAC/Reno continues to add intermediate cover on the south area of the landfill
to comply with KDHE’s regulations.
The County continues with hydrogen sulfide measurements on the north and east
side of the landfill on a continuous reading meter. The meters show next to no
detectable levels of hydrogen sulfide. The Department also continues with daily
checks in the mornings by "sniffing the air" and has periodically detected
hydrogen sulfide odors, but not at levels measureable with our electronic detection
equipment.
The Agency for Toxic Substances and Disease Registry (ATSDR) agreed to do
additional monitoring in some neighborhood locations near the landfill. Due to
other demands on ATSDR’s resources, this monitoring may not begin for a few months.
