Problem
• There is benzene in Wellmont’s only water source.
• PFA is a suspected polluter
![Page 3: PIG FARMERS OF AMERICA Members Jessie, Elena, Kyle, and Nick](https://reader035.fdocuments.us/reader035/viewer/2022081513/568135d2550346895d9d3922/html5/thumbnails/3.jpg)
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 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
![Page 15: PIG FARMERS OF AMERICA Members Jessie, Elena, Kyle, and Nick](https://reader035.fdocuments.us/reader035/viewer/2022081513/568135d2550346895d9d3922/html5/thumbnails/15.jpg)
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.
