PIG FARMERS OF AMERICA
Members Jessie, Elena, Kyle, and Nick
Problem
• There is benzene in Wellmont’s only
water source.
• PFA is a suspected polluter
Mission
• To find the true contaminator
• Prove PFA innocent
• Keep Wellmont’s only water source safe
•Benzene
•
•
•
•
•
Colorless
Flammable
Toxic
Gas
Sweet Smelling
Benzene Levels
•High- Lots of benzene over .004
•Low- Some benzene under .004
•Negligible- So little benzene that it doesn’t make
a difference
Wells
• Test- tests water
• Production- gives
water used
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.
Groundwater Flow
•Found under surface
•Comes from precipitation and surface
water
•Aquifer-readily available ground water
•Groundwater flows downhill
•Flows perpendicular to contour lines
on a topographic map

Suspects We Eliminated
• 6 suspects’ runoff water doesn’t flow into any of
the test wells.
The six suspects are:
• Kem Kleen
• Corn and Soybean Farm
• Town Landfill
• Gas/Service Station
• Storm Water Runoff
• Sewage Treatment Plant
• Flow from coal mine through test wells showed
negligible levels of benzene.
Test Wells
• Jessie will show
you on the screen
where we put our
test wells
PFA Not Guilty
The test well results for benzene
were:
PFA: Negligible
EXCON: High 0.008mg/L
The Culprit
We came to the conclusion that Excon is the
culprit.
•The test well directly in front of Excon had a
high level of benzene.
•The other wells it flowed through had a high
or low level of benzene and no negligible
levels.
