RE: PCB Landfill, Warren County
Dear Mr. Meyer:
In response to your letter of June 12, I have reviewed the provided information on the referenced
facility. Particular attention was given to evaluating the head of water currently observed in the
upper leachate collector system. While the landfill predates conventional design, it is fortunately
a fairly easy system to analyze.
The interplay of measured precipitation, ground water elevations observed, and the head acting
within the upper leachate collector system are shown on Figure 1. Without leachate withdrawal,
the head within the leachate collector system is increasing at approximately 0.32 ft per year and
shows seasonal cycles. The seasonal head increases in late spring and decreases in late winter.
Both of the annual and seasonal trends are easily duplicated using HELP (Ver. 3.01) to model the
water-balance of the landfill system. Figure 2 shows the predicted height of leachate in the upper
collector during the initial five years of operation. Note that HELP easily replicates both the
linear increase and seasonal increase of head. As with field measure data, HELP indicates the
seasonal low will occur in late spring through early summer. The complete output of this
evaluation is provided as Attachment 1.
The HELP analysis was performed for only a 5 year period of time but does demonstrate several
important trends:
• The leakage out of the landfill ( 1st year -1.02", 2nd year -1.22", 3rd year - 1.31 ",
4th year -1.40", 5th year -1.50") increases with increasing head in the collector.
The leakage is very close to that predicted using a unit vertical gradient and a soil
liner permeability of= 1 x 10-7 cm/sec as was assumed in the analysis. This
indicates a loss of liquid from the landfill of approximately 40,000
gallons/year/acre.
• The increase in seasonal average peak heads on the clay liner ( 1st year -.64", 2nd
year -2:98", 3rd year -6.62", 4th year -11.8", 5th year -16.7") reflect cover leakage
being only slightly greater than losses through the liner. The measured

fluctuations in head, Figure 1 LMW-1 and Vent) were used to calibrate the
relative permeability of the two systems (liner vs. Cover). Figure 3 shows the rise
in head and seasonal effects obtained if the effective permeability of each system
is reduced one order of magnitude. While the rate of head rise remains
reasonable, the seasonal effects are shifted in time and reduced in magnitude
compared to those actually observed.
My feeling is that the leakage to date is lost in the partially saturated soils that lay between the
bottom of the liner and the ground water table, i.e., the storage potential of these soils exceeds
past leakage from the landfill.
An additional HELP analysis was performed to evaluate what would occur if the leachate
collection system were maintained, that is pumped to limit head build up. Attachment 2 provides
the HELP model that clearly indicates that this would be sufficient to limit head buildup and
would achieve a steady-state leakage of approximately 35,000 gallons/acre/year. The continued
lack of use of the leachate collection system (LCRS) is placing an unnecessary additional
quantity of leachate in the ground. The required withdrawal rate is very small, so that even the
very limited capacity of the existing LCRS system can be beneficial.
It is also obvious that the performance of the landfill can be dramatically improved as follows:
• Leachate should be continually pumped from the leachate collection system using
a low capacity pump ( ::::0.15 gpm) that will not over-pump the collector system
but will reduce the head acting on the liner. This is a very slow rate.
• By upgrading the final cover using components that were not available in 1982,
the already low leakage through the final cover can be dramatically reduced ( see
Attachment 3). These components include a geocomposite drainage layer over a
40-mil PVC or LLDPE geomembrane.
Current Cover
1st year -2.43"
2nd year -2.72"
3rd year -2.05"
4th year -2.21"
5th year -2.74"
Current Cover w/ New GM & Drainage Layer
0.0002"
0.0002"
0.0002" ( 0.0002" "' 5.50 gal/acre/yr)
0.0002"
0.0002"
The more than 4 orders of magnitude decrease is obtained by simply replacing the
current PVC geomembrane in the existing cover with a properly CQA installed
40-mil fl_exible geomembrane and the addition of a lateral drainage layer. This
dramatically reduces the head acting on the clay liner system. Once the existing
excess liquid in the landfill is removed, there is also no future need for leakage
Page 2
pumping from the LCRS.
I estimate that the cost to replace the existing cover geomembrane and add a drainage layer is
approximately $120,000 for the roughly 2 acres involved.
I believe the PCB landfill can be economically upgraded to provide a level of performance that
ensures protection of the environment and the citizens of Warren County at less risk that the
alternative of removal of the waste. The upgrade also has the advantage that after the existing
excess head is removed, no future pumping will be required.
Please feel free to contact me if you have any questions regarding my review.
Cordially,
