Water Well Survey

North Jackson Company 1004 Harbor Hills Dr., Suite 102 Marquette, MI 49855 906.225.6787

Memorandum January 25, 2006 To: Steve Donohue, Foth and Van Dyke From: Dan Wiitala CC: Jon Cherry, Kennecott Minerals Company Dennis Donohue, Warner, Norcross & Judd RE: Eagle Project, Water Well Survey

Water well surveys using state and county databases have been performed as part of the Stage 1 Environmental Baseline Hydrology Study and for the supplemental hydrogeological survey for the groundwater discharge permit. An updated database survey was completed for the comprehensive summary hydrogeologic study report in an area surrounding the Eagle Project. The following databases were searched for this survey:

1. Marquette County Health Department Records

2. Michigan Department of Environmental Quality (MDEQ) Scanned Well Logs 1965-1999 http://www.deq.state.mi.us/well-logs/

3. MDEQ Wellogic database http://www.deq.state.mi.us/wellogic/main.html

The search area encompasses approximately 75 square miles covering the Yellow Dog Plains (Plains) in Marquette County (Figure 1). This area includes the physical limits of the Quaternary alluvial aquifers of the Plains. Within this search area 7 water wells were found in the databases. The locations are shown on Figure 1 and described in Table 1. The logs for each of these wells are attached to this memo.

Inconsistencies have been found in several logs for information describing the well location. Reported locations on the logs using public land survey system grids and, in some cases, latitude and longitude, have also been checked using well owner names reported on the logs cross-referenced to property ownership shown in the 2004 Marquette County Plat Book. Using this method, it appears that some location data reported on some of the well logs are in error. The locations shown on Figure 1 are presented as the best estimate of the actual well locations using all of the information listed above.

Figure 1 also includes the location of the Powell Township Wellhead Protection Area, which lies north of the well survey area.
