Dear Mr. Taylor:
I enjoyed talking with your about your club's deer hunting interest in Warren County. I will
attempt to respond to your concerns with respect to the potential affect of the Warren County
PCB Landfill on the deer population in the vicinity of the landfill. In addition, you should be
aware that a group of citizens from Warren County, grass roots environmental representative and
State personnel are members of a Joint Warren County State PCB Landfill Working Group that
is currently working together to detoxify the landfill . This Working Group will be made aware
of your concerns. ? •
,
The PCB Landfill contains approximate~OO cubic yards (54,750 tons) of soils
contaminated with an average of350pp • CB parts per billion levels of chlorobenzenes, and
parts per quadrillion levels of dioxins. e chemicals are associated with electrical
transformer fluids removed from State road shoulders in 1983 . The landfill containment system
includes compacted clay liners from 2 to S feet thick and a plastic liner of 30 mills thickness on
the bottom and sides and 10 mils on top. A leachate collection and removal system is in place to
remove water from he landifll. A sand filter and carbon filter treatment system is utilized to
treat any water removed from the landfill. The treated water then can be irrigated to the grassed
surface of the landfill cap. The landfill contains water from several rainfall events that occurred
which the contaminated soils were being placed in the landfill. A cross section of the landfill
design is enclosed .
The containment systems for the landifll is monitored by a sand layer below the bottom liner and
beneath the entire floor of the landfill. The sand layer is connected to a riser pipe to the surface
for evaluating moisture that may leak through the bottom liner. In addition there are four
groundwater monitoring wells located north, south, east and west of the landfill. Surf ace water
is monitored upstream and downstream of the landifll on Richneck Creek and an unnamed
tributary of the creek. There is a single air vent in the center of the landfill for air quality
monitoring. The leachate collection and detection system, filter systems, sedimentation pond

and surface soils are also monitored. A map indicating the location of the external monitoring system is enclosed.
P. 3
The State has sampled and analyzed all the monitoring stations multiple times per year for the past 12 years. AU the data generated indicates that there has been no measured releases of PCB from the landfill. Recently the State and the Science Advisor for.the Working Group
implemented a dioxin analysis of some of the sampling stations. The dioxin analytical method used by the State was the most sensitive detection method available for dioxin. Some low levels of dioxin (parts per quadrillion) were apparently indicated in some of the groundwater
monitoring wells and a stream water sample. I have stated the term "apparently" very deliberately. The State's perspective is that dioxins are ubiquitous in nature and the potential for analytical error, at the sensitivity and detection level utilized, is such that no clear scientific
con~lusion can be made from the limited data. The State believes that additional testing for dioxins are needed for a better scientific evaluation of dioxins. Members of the Working Group have a different perspective of the dioxin data, which includes the view that the data indicates dioxin releases from the landfill since it is the only apparent source of dioxins. This issue represents a strong but honest difference of perspective and I want to bring this to your clubs attention in fairness to the Working Group.
It is the State's perspective that the Warren County Landfill is a s~re facility that is not releasing contamination to the environment. The containment systems including the surface cap and chain link fence around the landfill are sufficient to preclude any exposure of contaminants to deer population in the area. Deer in the area may be consumed by the public without concerns
that body burdens of any contamination result from the PCB Landfill.
If the hunting club would like a more formal presentation of data and/or a site visit to the PCB Landfill, please let me know and I will arrange them for you. If I can be of further assistance, please contact me at [phone].
