Reference: PVC LANDFILL LINER DEGRADATION
Dear Mr. Musslen:
It was a pleasure to talk with you yesterday, July 2, 1997, regarding the PVC liner at the
Warren County PCB Landfill. As you are aware earlier this year, S&ME's Singleton
Laboratory conducted a number of tests on the liner material including thickness, density
and tear resistance. The results of these tests were reported in late March.
I wanted to take this opportunity to go over several of the testing capabilities now
available at S&ME. One such capability we spoke of yesterday was our ability to
weather/age materials to see how they will respond over the course oftime. Additionally
we can take a sample of liner material, weather it, and back in results to determine how
the material has responded up to the present. Other testing capabilities for landfill liners
include:
• Moisture Content
• Thickness Measurements
• Density (Unit Weight)
• Specific Gravity
• Dimensional Stability
• Seam Shear
• Seam Peel
• Tensile Property
• Tear Resistance
• Carbon Black Content
• Melt Index
• Hydraulic Burst Strength

• Puncture Strength
• Grab Tensile Strength
• Trapezoid Tear Strength
• Water Permeability
• UV Weathering
S&ME still has sufficient material from previous testing of the Warren County PCB
Landfill liner to conduct some weather testing should you decide to do so.
I am enclosing a Statement of Qualifications for S&ME's Singleton Laboratory. If you
have any questions, or we can be of further assistance please contact either Don Carter in
our Raleigh office or me at [phone]. Thank you for your time.
Sincerely:
S&ME, Inc.
