Thanks for the question. One of the slides I didn't get to really spoke to the issue. There are a couple hundred thousand water wells drilled in Alberta. The data from Alberta Environment's records show that at least 26,000 of those wells have been drilled through. The coal seams have encountered them. The data further indicates that there are probably 900 gassy--as they call them--water wells shown in their records that are indicative of the challenge of the geology that Mr. Schwartz spoke about. The gases there are naturally occurring. The fact that they are occurring and that you're seeing the fires, or the explosions as they're reported, in some of these wells is a result of the naturally occurring gas migrating into those water wells.
