TCE in Ground Water
By Linlin Wang

2. Trichloroethylene (TCE)
What is Trichloroethylene?
What happens to trichloroethylene when it enters the environment?
How might we be exposed to trichloroethylene?
How can trichloroethylene affect our health?

3. TCE Concentration Distribution

4. EPA Defined Groundwater Contamination
EPA Limit: >17ppm is contamination

5. Where Exceeds EPA’s Drinking Water Limit?

6. Public Use Groundwater Source
-Drinking water
-Recreation

7. Identify Public Use Groundwater that Exceeds EPA Limit

8. Where the most terrible thing happens?

9. Possibility Study of Cancer Rate Related to TCE Distribution in Groundwater

10. Conclusions Conclusion: Future Work -Large Range from 0~240 ppm
-Central and East Problem
-Possibility of Cause of Cancer
Future Work
-Find out Source of TCE
-Investigate the Possible Route of TCE Transport
