Below are resources which detail the scientific evidence justifying concerns about fracking.
- Cracks in the Facade – Water Contamination – Fractures can extend for 2500 ft and frequently to 1000ft, and can spread to neighbouring wells.
- Methane contamination of water, April 2011 – Shows very large increase of Methane up to 1km from active wells with concentrations high enough to be an explosive hazard. Heightened methane levels also found up to 4.5km from inactive wells.
- Fracking contribution to truck traffic – Trucking stats suggest that transportation related to fracking could account for 4.5% of US truck loads and 26% of tank loads
- Air samples reveals high emissions from fracking – Air samples near Denver suggest as much as 4% of methane may be leaking from fracking sites.
- Frac Focus – Chemical disclosure registry – Texas drilling operators will have to provide this site with details of chemicals and water used (starting Feb 2012)
- Greenhouse gas footprint of shale gas – Shows that shale gas has from 20% to 100% greater contribution to GHG than coal over a 20 year period, and similar effectover 100 year period. Methane leakage during production is 30% to 100% more than conventional gas.

- A first look at EU shale gas prospects. Deutsche Bank Oct 2011 – Assessment suggests more limiting factors and higher cost in Europe than in USA so will not have nearly as significant in impact on gas prices. UK break-even costs approx twice that of US European Gas.
