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 aTIFF (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
• Kem Kleen- a• Corn and Soybean Farm- b• Town Landfill- c• Gas/Service Station- d• Excon- e• Coal Mine- g• Factory Pig Farm- h• Storm Water Runoff- i• Sewage Treatment Plant- f
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 CulpritWe 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.
