Leachate collected from the lined cells is currently piped to a
leachate collection pond, and then pumped into trucks and taken by road
back to the water filtration plant in Charlottesville.
|
There are currently three plumes of highly contaminated ground
water from the unlined cells in the three main drainage areas of the site.
The contaminated water is sinking down to the aquifer and progressing
into the surrounding area.
|
The current management of overland runoff through a handful of
sedimentation ponds is insufficient to stop the flow of potential contaminants
into the surrounding streams feeding into Mechum's River.
|
Currently the occupation of Ivy landfill is limited to employees
of the landfill and infrequent visits by citizens dropping off waste.
|
|
We propose to connect the existing leachate collection pipes into
a sewer line which ties into the existing sanitary sewer systems of the
county and city. The leachate will be treated along with standard waste
at the sewage treatment plant. This sewer line will service the site
as a sanitary sewer when occupation is reintroduced to the site for large
scale events, and/or when the leachate production eventually ends.
|
The flow of the plumes will be stopped with the introduction of
slurry walls in the plume areas at the edge of the site. Contaminated
ground water will be pumped from wells into the sewer line; monitoring
wells will test the water downhill from the slurry walls.
|
We propose to control storm water through planting which will slow
the flow of water, stabilize the soil to control erosion, and filter the
contaminants from the water before they reach the surrounding streams.
|
The perimeter is a charged area between the active dump and the
surrounding neighbors which can accomodate occupation now. This perimeter
occupation will provide an audience for the winding down and closing of
the landfill cells and the construction of the remediation infrastructure.
