25
What is Fracking?
- technique, in water, is mixed with SAND and CHEMICALS, and the mixture is injected at high pressure into a well to create small fractures * extracts oil beneath sand
26
What are 3 main concerns with Fracking?
1. Each well requires approximately 5-8 million gallons of fresh water which is then polluted and cannot be cleaned 2. Ground water may be exposed to carciongens and radioactive gas 3. Methane gas produced
