In 1989, there were four complete alluvial well field tests taken at the Bear Number Three Minesite. These tests were taken on the following dates: March 21, 1989; July 7, 1989; August 16, 1989; and October 26, 1989. Copies of the results of these field tests are enclosed herewith. In addition to the field tests, bottle samples were taken from both wells on October 24, 1989. These samples were submitted to ACZ Laboratories, Inc., for analysis. Copies of the results of these analyses are enclosed with this report. In response to our submittal of the 1986 Annual Hydrology Report, we received a letter from you on March 21, 1989. This letter outlined the suspi- cion on the part of the Division that alluvial well AA1 had been contaminated by surface water and that as a result the conductivity levels of the well were not representative of the level contained within the alluvium. The letter also requested that Bear submit a schedule for the drilling of a new well to replace AA1. This request was complied with and on July 7, 1989, the new well was completed. In 1989, there were no discharges from either of the sediment ponds at the Bear Number Two Mine or the Bear Number Three Mine. For the year 1989 we estimate that the entire operation at the Bear Number Three Mine consumed a total of 672,000 gallons of water. There were no outflows from the mine during the year.
