In 1988, there were four complete alluvial well field tests taken at the Bear Number Tnree hlinesite. These tests were taken on the following dates: March 31, 1988; May 10, 1988; September 14, 1988; and December 13, 1988. The • May 10, 1988 field test was taken in the presence of Cathy Begej and Tun King with CMLRD. Copies of the results of these tests are enclosed for your information. In addition to the field tests, bottle samples were taken from both wells on December 13, 1988. These samples were subrnitted to ACZ, Inc., Ccnmercial lab Division for analysis. Copies of the results of these analy- ses are enclosed with this report. On July 13, 1987, we received a letter from Ct,'L,RG dated July 8, 1987. In this letter, Bear was instructed to "investigate the integrity and viability of well AA-1". In order to comply with this request we took twu bottle samples from each well and submtit±ed them to ACZ, Inc., for analysis; and requested their recommendations concerning well AA-1. On March 8, 1988, ACZ recamiended that we obtain a different well bailing mechanism and m;dify our sampling procedures so that the results of our sampling would more ac- curately reflect the quality of the water in the alluvium. This was done, and the N,ay 10, 1988 sampling was the first in which we utilized our ne.~ equipment and procedures. As can be seen fran the results of this sa;;ple and ones taken subsequent to it, our efforts have been successful in that the conductivity levels in the samples taken from AA-1 have stabilized. Based upon this information, we do not believe that it will be necessary to replace this well.
