Colorado KO?U?-3615 <br />3D3 ^J3 710n Tel <br />jli3 '7479u1 Fas <br />This letter summarizes analytical testing results for environmental samples collected during <br />Dames & Moore's preliminary site assessment of the Montgomery Pit Facility. The Montgomery <br />Pit facility is operated by B&B Excavating, Inc. (B&B). The facility is located approximately 2 <br />miles west of Eagle, Colorado. <br />Dames & Moore collected environmental samples at the Montgomery Pit facility on November <br />12, 1998. These samples were submitted to Evergreen Analytical Laboratories, Inc. in Wheat <br />Ridge, Colorado, on November 13, 1998. Evergreen analyzed the samples for chlorinated <br />herbicides (weed killers), volatile organic compounds (VOCs), total recoverable petroleum <br />hydrocarbons (TRPH), and oil and grease. The purpose of collecting and analyzing these <br />samples was to identify chemical substances released at the facility and provide data supporting <br />the preparation of a more comprehensive sampling and analysis plan (SAP). This sampling <br />was not intended to fully characterize the nature or extent of contamination at the site. <br />The results of the analytical tests are summarized in Table 1. This table presents the sample <br />names, descriptions, and analytical test results for the samples collected on November 12. The <br />complete laboratory test report is attached to this letter. The test results presented in Table 1 <br />are summarized, as follows: <br />The -% inch road base sample, MPSP- A60, contained 2,4-D (1.1 mg/kg), TRPH (240 <br />mg/kg), and oil and grease (30 mg/kg). MPSP-A60 contained no VOCs in concentrations <br />above the method detection limits. While 2,4-D was present in this sample, the weed killers <br />concentration was below the limits established under RCRA land disposal restrictions <br />(LDRs). Test results for sample MPSP-A60 also show that virtually all the TRPH detected in <br />the sample consisted of diesel-range organic compounds. <br />• Both the -'/. inch road base and the washed sand samples contained no 2,4-D or other <br />contaminants that would indicate they were impacted by any chemical releases that may <br />have occurred on the site. <br />1\DEN1 \VOL 7 W ROJ\BBBV'ANTGMRVLLETTERSW H ILIP3.DOC <br />Olfces Worldwide <br /> <br />
