Current regulation prohibiting the co-mingling of groundwater may conflict with CBM/NGC development objectives • The need to protect current water users who obtain the water from coal zones that may be targeted for CBM/NGC development • The anticipated need, in some cases, for de-watering coal zones for CBM/NGC development, verses protection (sustainability) of the aquifers
Overall conclusion from Alberta Research Council review of Lauridsen Water well Complaint: Dec 20, 2007 • The Alberta research Council’s overall conclusion of the evidence from the review of the AENV and AEUB files, along with a new review and evaluation of additional data and aspects, is that energy development projects in the area most likely have not adversely affected Ms. Lauridsen’s water well. energy development projects in the area most likely have notadversely affected Ms. Lauridsen’s water well.
