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.
