To further discuss the issue of records, yes, more data is absolutely needed to precisely match the methane, ethane, propane and butane in the contaminated citizen water wells to "specific resource" wells but it's not more water well data that's required, it's data from Encana's gas wells. The company frac'd about 200 gas wells in the fresh water zones in the area, but Alberta Environment only sampled one of those for isotopic analysis). One of the reasons Ms. Ernst is suing Alberta Environment is negligent investigation - under the Water Act, it's their responsibility to investigate contamination and law violations by oil companies, not Ms. Ernst's.

To determine which resource wells caused the water contamination in the many contaminated water wells at Rosebud, "specific" gas sampling and fingerprinting analysis is required from each Encana gas well in the impacted area. Ernst is not permitted to collect such data, nor should she be required to. She didn't break the law, Encana did.
