It should <br />be noted that the analysis was performed on a portion of the original core <br />samples as taken during the investigation of November 8, 1985. The sample <br />ID numbers (i.e., HS -1, 2, and 4), listed as "Client No.," were retained for <br />reference to the original set of analysis as performed by the same lab for <br />metal and organic screening. <br />The results of the testing series indicate the lead levels of the extract <br />are below the detection limit as indicated by the <0.01 mg/l concentration in <br />each of the samples. <br />HFG/cdj <br />Attach. <br />cc: Mr. Richard G. Azevedo <br />Mr. Hugh McGrade <br />Mr. Renaldo Crooks <br />Mr. Louis R. Garcia <br />Sincerely, <br />Harold F. Grinde <br />Director of Energy and <br />Environmental Affairs <br />s <br />
