The Kerr Investigation - Where Can We Go From Here?
When some Canadian landowners noticed changes in their property, they suspected that CO2 being stored deep underground had begun to leak to the surface. After two different investigations reached opposite conclusions, IPAC-CO2 asked experts from The University of Texas at Austin to undertake an independent investigation. These are the results.
