Week ending December 12, 2005
APAC-Reno continues dewatering the waste fill area with the
construction of a drainage collection system on the south side
of the lower pond area. The contact water in the waste fill area
flows into the lower east pond which is then chemically treated
to improve water quality. APAC-Reno is discussing plans for disposal
of the treated pond water with the Kansas Bureau of Water and the
County Wastewater Department.
APAC-Reno is drilling and completing about one landfill gas
collection well per week during this cold winter period.
APAC-Reno will complete the well drilling operation for
the hydrogeologic investigation during the next week when they
drill one additional groundwater well located near the lower
pond area. Groundwater well sampling is also expected to
begin next week.
Intermediate soil cover over the south waste fill area continues,
but was very slow during the week due to the weather.
APAC-Reno and KDHE are finalizing the details of an extensive
air monitoring program covering the landfill perimeter areas and
on-site locations. The air monitoring will include new low level
detection hydrogen sulfide monitoring units, continuous monitoring,
and transmittal of the monitoring data to KDHE, JCED, and the ATDSR.
Air monitoring continues with APAC-Reno and the County conducting
daily monitoring. Hydrogen sulfide odors in the atmosphere have been
noticed on some days at the perimeter roads but have not been detected
with the current hydrogen sulfide monitors. The ATDSR is routinely updated
on the air monitoring results.
