Rosebud water is not being affected by coal bed methane, rather by treating bacteria says the EUB (now AER)

Rosebud water is not being affected by coal bed methane by Darren Ridgley, September 26, 2006, Drumheller Valley Times
The advisory was issued and the residents were informed after tests at the hamlet’s new water treatment facility showed that the water supply had a bromodichloromethane level of 19 parts per billion (ppb). The new Canada Health guideline for bromodichloromethane is a maximum level of 16 ppb. Bromodichloromethane is a chemical byproduct created when the chloride used to treat all drinking water reacts with bacteria present in the water. After the response to the situation began, concerns had allegedly been voiced to the Energy and Utilities Board (EUB) as to whether or not the water issue was related to coal bed methane sources around the area. “I had heard that there were some people that were saying it was (coal bed methane) when the report clearly stated that it was not coal bed methane related,” said Darin Barter, a spokesperson for the EUB. “It’s my understanding that Alberta Environment’s investigation was stemmed from concerns about coal bed methane and what really turned up was a water treatment plant issue.” [Emphasis added]
