RE: COLLECTION AND DISPOSAL OF LEACHATE AT THE PCB LANDFILL
Several modifications in the leachate collection and disposal
system are necessary in order to determine the amount of leachate
being generated, the recharge rate, and the levels of PCB in the
treated leachate prior to disposal. There is a need for some
immediate measures to be taken as soon as possible and also a need
for some more permanent measures to be made as a long range solution.
IMMEDIATE MEASURES NEEDED:
1. A water level indicator and accessory equipment should be
purchased and installed in the leachate collection system in
order to determine the water level in the system and
calculate the recharge rate.
2. Several 55 gallon drums should be purchased to collect and
store leachate until samples can be analyzed in order to
decide the proper method of leachate disposal.
3. The outfall pipe from the leachate treatment system should be
extended in order to allow the use of the storage drums.
PERMANENT MEASURES NEEDED:
1. A larger leachate collection and storage container should be
purchased and installed to store larger quantities of
leachate until it can be properly disposed.
2. The fence around the landfill should be extended around the
leachate storage container and/or the leachate lagoon in
order .to inhibit public access to this area.
The above measures are recommended in order to enable the Solid
Waste Section to better assess the effectiveness of the leachate
collection, treatment, and disposal system. Further modifications to
the system may become necessary after leachate levels and recharge
rates are determined.
