Hydrogeological Background Study Proposed Gravel Pit SE W5M Brent Lennox, M.Sc., P.Geol. Waterline Resources Inc. December 10, 2012 Sources of Information Regional geological and hydrogeological mapping (Ozoray and Barnes, 1977; Shetsen, 1987; HCL, 2000; Budney et al., 2004, TGWC, 2012) Water well records from AESRD water well database (AESRD, 2012) Approvals search (AESRD, 2012) Site test pitting Regional geological and hydrogeological mapping (Ozoray and Barnes, 1977; Shetsen, 1987; HCL, 2000; Budney et al., 2004, TGWC, 2012) Water well records from AESRD water well database (AESRD, 2012) Approvals search (AESRD, 2012) Site test pitting Study Area Proposed Development Extent of Aquifer Bearberry Creek Red Deer River Regional Groundwater Flow Direction Distance from Site to: Red Deer River: 2 km south and 6 km east Bearberry Creek: 2.3 km northeast Regional Geology/Hydrogeology Gravel Sandstone/ Shale 0.9 m Ground Overburden/Bedrock Contact: 5 to 29 m regionally, >4.5 m at site, 29 m at water well record within site quarter Average Depth to Water at Site = ~3.2 m = Vertical Gradient Proposed Depth of Excavation Topsoil/Silt Rates of 11 to 273 L/min within 1.6 km radius Water Wells Proposed Development Quarter Section 61 well records within 1.6 km radius, majority use gravel horizon as water source (AESRD, 2012) Closest residences are in NE corner of site quarter section, 550 m NW, 725 m NE, 1.2 km E, numerous >80 m S based on aerial photographs One water well in quarter section installed in bedrock aquifer Whats Next Still in preliminary stages of application process Approval to divert water via evaporation from the end pit lake in process with Alberta Environment Waiting on Alberta Environment to determine if there are additional regulatory requirements Still in preliminary stages of application process Approval to divert water via evaporation from the end pit lake in process with Alberta Environment Waiting on Alberta Environment to determine if there are additional regulatory requirements
