Monitoring System at the PCB Landfill, Warren County, North Carolina
Gentlemen,
This memorandum provides information on the monitoring equipment which has been installed
at the PCB landfill in Warren County. The system consists of a battery powered data logger
(computer), and instruments which monitor and record rainfall, ambient temperature, ambient
pressure, and water levels within the landfill. Water levels are being monitored in the two new
borehol s which were put in the landfill in February, 1997.
The instruments take measurements once per hour, and the results are stored in the data logger
(rainfall is cumulative and the hourly total is stored). Periodically, division staff go to the landfill
and download the stored data from the data logger into a laptop computer. Reports can be
generated and the data is available in comma delimited ASCII files for import into most common
data ha e and spreadsheet programs. Currently the data is downloaded every 7-10 days, but the
battery is expected to last for at least 30 days in the winter, more in the summer.
The instruments were installed and the system debugged on September 23 and 24, 1997. Hourly
reading have been recorded since two PM on September 24. Data was last retrieved October 3.
One water level instrument was installed in the south borehole. Additional cable is required to
install the second instrument in the north borehole. The cable has been ordered and it is expected
that it will be installed before the 15th of October.
A summary of the equipment installed at the landfill may be found on the attached specifications
sheet. If there are any further questions, please do not hesitate to contact me.

Specification Sheet
Met One Instruments, Grants Pass, Oregon. Model 457. An enhanced
Campbell Scientific CRl O Data Logger.
Campbell Scientific digital to analog interface. Used to communicate with
the VS Piezometers.
Lowes, 12 volt, 135 amp-hour, rechargeable lawn tractor battery.
Slope Indicator, Vibrating wire strip piezometer. Used to measure
pressure, thus water level elevations and changes in the boreholes. Very
accurate,+/-0.001 feet. The instrument is used to measure water levels in
the landfill. It was zeroed with measurements taken manually with an
electronic water level indicator. The instrument converts water pressure to
a tensional load on a fixed steel strip (similar to a tuning fork). Tension
increases linearly with pressure. A magnetic coil excites the strip, which
vibrates at a known frequency. The vibration excites the strip which
vibrates and generates voltage pulses. These pulses are counted, calibrated,
and converted to an elevation of water for the output.
Custom written. Meteorological portion by Met One, VSP by Slope
Indicator, debugged by division consultant.
Met One, Model 090D-solid state barometer. Provides absolute (site
specific) pressure. Monitors and calibrated for 26-32" of Mercury (Hg)
pressure. Temperature rated for -18 to 50 degrees C (-0.4-122 degrees F).
Accurate to +/-0.04" of Hg.
Met One, tipping bucket. Model 370, 8". Measures 0.01" ofrain. Mercury
switch. Accurate to+/-1 % at 1 "-3" ofrain per hour, at 70 F.
Campbell Scientific. Model 107 with a model 41301 radiation
shield. Mounted on and 8 foot PVC pole. Range -35-50 degrees C.
Sensitivity of<+/-0.4 C within -24-48 degrees C (-11.2-118.4
degrees F).

Re: Preliminary Data From the Monitoring System at the PCB Landfill, Warren County,
North Carolina. September 24-October 9, 1997.
Gentlemen,
Attached you will find several examples of data collected from the monitoring equipment
recently installed at the landfill, as well as similar results of historical data collected from the
landfill vent. For reference the attachments are labeled as follows:
Attachment 1 Example of data logger report-Data from September 25-29, 1997.
Attachment 2 Microsoft Excel spreadsheet summary of data logger data, September 24-
October 9, 1997. Note summary on page 1.
Attachment 3 Graph of Hourly barometric pressure and water levels in south borehole,
September 24-October 9, 1997.
Attachment 4 Microsoft Excel spreadsheet of water elevations measured in the landfill
air vent monitoring point. December 1994 through September 1997. This
spread sheet also contains the monthly and yearly rainfall data for the
Arcola station in Warren county. The average barometric pressure for the
day, as recorded at RDU and adjusted to sea level is also included.
Attachment 5 Air Vent water levels versus RDU(sea level adjusted) barometric pressure
graph. Monthly for 12/94 through 9/97.
Attachment 3 clearly shows that the water level measured in the south borehole fluctuates in
direct correlation with the atmospheric (barometric) pressure. During the period of record, the
water level measured in the borehole fluctuated by 13. 2 inches and the barometric pressure
varied by 0.89 inches of mercury, often showing response hourly. It is important to note that the
change registered by the VSP is in tenths of a foot ( ~ 1.2 inches) The highest reading came during
a spell when the barometric pressure was the lowest, and the lowest water level was recorded
during times when the atmospheric pressure was the highest.
When atmospheric pressure is high it "pushes down" on the water surface, thus lowering the
recorded elevation. When the pressure is "low" there is less force on the water so it "rises"
accordingly. For reference, 12" of water column is equal to 0.883 inches of mercury (Hg).
During this time period only 0.85 inches of rain fell, hardly enough to generate the water level
swing measured, even if it had all entered the landfill, a highly unlikely assumption.
Attachment 5 also clearly shows that there is a relationship between the barometric pressure and
the level of the water that is measured in the landfill air vent. Attachment 4 is a record of the data
collected by the division and used to generate the graph. Attachment 4 provides a statistical
analysis of the air vent data. The data is summarized for the period ofrecord (12/94-9-97) as
well as for each year of record (1995, 1996, 1997 to date). The data clearly shows that the
fluctuation in the measured air vent water level was 9" in 1995 and 13.32" to date in 1997, less
than or equal to measurements of fluctuation collected in ten days with the monitoring
equipment.
The year of 1996 showed a total fluctuation of measured water level in the air vent of 21.6
inches. HOWEVER it must be noted that the spread in the barometric pressure was almost one
inch of Hg (0.98") versus a spread of about 0.5. inches of Hg in 1995 and 1997, to date. It is also
important to note that the yearly rainfall, reported by the Arcola station, was 40.28 " in 1994,
56.85" in 1995 and 60.58" in 1996, well above the NC average of approximately 45 inches per
year.
In an effort to "even out" the air vent information, the data was analyzed for an average (mean) ,
medium, as well as maximum and minimum recorded value for the time period of concern. The
yearly averages were then averaged, and indicated a spread of 9.378 inches, well within the
fluctuation recorded in just 10 days in the south borehole. If one compares the borehole data
(means), there is an indication that water is entering the landfill. This is consistent with the
evaluations of both Barnes and Richardson. The average water level, as measured in the vent,
appears to be slowly increasing. The data for the summer of 1997 records that the water level in
the landfill maybe increasing. However, the rainfall for the summer of 1997 was well below
normal (August 1997 was the second LOWEST recorded rainfall amount, at RDU, in the last 100
years).Ifthe landfill were leaking any measurable amount, then why are the measured water
levels increasing?
The data clearly needs more interpretation. It is clear that the measured water levels in the
landfill fluctuate with the atmospheric pressure. Historical data from the air vent, appears to
show that the water level in the landfill is slowly increasing. In my opinion, there is no indication
that water is leaving the landfill ( as evidenced by an increase in the measured water levels
during a time of minimum rainfall).
In analyzing the data from the landfill, one must be cognizant of the relationship between the
measured water level and the barometric pressure. Analysis to date does not include the behavior
of the landfill system, including the contribution of any internal gas pressure in the landfill.
In summary, the measured level of the water in the landfill rises and falls in good correlation
with the ambient barometric pressure. The hypothesis, as presented by Barnes and Hirschorn
that significant amounts of water are entering the landfill and leaving the landfill is incorrect. The
bottom liner appears to be intact. Observed increases in the water level in the landfill can be
related to barometric pressure swings, and possible, minimal infiltration of water into the landfill.
