Methane WE&M.jpg

C & EN has reported (Methane Fouls Well Water, May 16, 2011) the results of a study linking the hydraulic fracturing of organic-rich shale deposits to the contamination of residential well water supplies.

 

Although unrelated to the current controversy over fracking, some of the issues raised brought to mind the decades-long series of studies that have been conducted with respect to the treatment of methane-bearing ground water supplies in Illinois. A review of this work was presented in Water Engineering and Management in 1999.
