June 2007
No odor complaints received by APAC, Johnson County or KDHE.
- No detectable readings at the ambient air monitors.
- Average landfill gas concentration in June: Methane 12.7%; hydrogen
sulfide 37 parts per million (ppm).
- An estimated 1,944,000 cubic feet of landfill gas was removed and treated in
June.
- An estimated 2,817,391 gallons of contact water (water that has
seeped through the landfill and accumulated underneath the
landfill) and 210,679 gallons of well water (installed in April,
2007 in the southwest corner of landfill) were removed and
treated in June.
July 2007
No odor complaints received by APAC, Johnson County or KDHE.
- No detectable readings at the ambient air monitors.
- Heavy rains at the end of June and beginning of July amounted to more than 10
inches at the APAC site causing high water at the lower pond. The
telemetry system at the West Seep location was impacted by water.
The hydrogen sulfide monitor was cleaned and checked and continued
to log data. The telemetry system that transmits data from the
monitor to the safety building was removed, rebuilt, and
reinstalled. During the time that the system was being rebuilt the
remaining seven monitors and two telemetry systems continued to
operate properly. The monitor at the West Seep was checked
regularly by Stinson Environmental Group personnel and no hydrogen
sulfide was recorded.
- Average landfill gas concentration in July: Methane 35.5%; hydrogen sulfide 35-40
parts per million (ppm).
- An estimated 2,008,800 cubic feet of landfill gas was removed and treated in
July.
- An estimated 2,688,000 gallons of contact water (water that has
seeped through the landfill and accumulated underneath the landfill)
and 188,866 gallons of well water (installed in April, 2007 in the
southwest corner of landfill) were removed and treated in July.

August 2007
- Between August 16th and 28th, during the
moving of a compost pile located near the southern property line,
hydrogen sulfide released during this activity was detected at the
perimeter monitors. The peak reading was 0.3 ppm at the southeast
monitor between 10:30 am and 11:00 am on August 20th. The next
highest reading was 0.12 ppm at the same monitor detected between
8:00 am and 8:30 am on August 16th. Additional readings from 0.01
to 0.1 ppm were detected at the north, northeast, east and southeast
monitors on 8/16, 8/20, 8/21, 8/23, 8/27 and 8/28.
- Average landfill gas concentration in August: Methane 37.5%;
hydrogen sulfide 35-40 parts per million (ppm).
- An estimated 2,008,800 cubic feet of landfill gas was removed and
treated in August.
- An estimated 3,501,051 gallons of contact water (water that has
seeped through the landfill and accumulated underneath the landfill)
and well water were removed and treated in August.
September 2007
- No odor complaint received by KDHE, JCED or APAC-Reno. No
detectable readings of hydrogen sulfide on the monitors.
- An estimated 1,944,000 cubic feet of landfill gas was removed
and treated in September.
- An estimated 3.444,218 gallons of contact water (water that has
seeped through the landfill and accumulated underneath the landfill)
and well water were removed and treated in September.
