Monthly <br /> equipment inspections and dissolved oxygen readings will be measured in wells MW-4 and <br /> MW-7. <br /> • Quarterly sampling of well MW-7;ground water samples to be analyzed for methyl tertiary- <br /> butyl ether (MTBE) and tertiary butanol (TBA) in accordance with EPA method 8260B. <br /> Depth to ground water will be measured for all wells during the quarterly events. <br /> • Annual sampling of down-gradient wells MW-4 and MW-5 (during the 3rd quarter of a given <br /> year); ground water samples to be analyzed for MTBE and TBA in accordance with EPA <br /> method 8260B. <br /> • Temporary suspension of ground water sampling in remaining wells due to consistent <br /> historical non-detection of constituents in those wells; and <br /> • Preparation of quarterly reports presenting results of field work conducted at the site. <br /> If you have any questions or require additional information, please do not hesitate to contact our <br /> office at (209) 467-1006. <br /> Sincerely, <br /> Advanced GeoEnvironmental, Inc. �oF�S; R. <br /> Ci���% <br /> No. 7473 <br /> Ally Colavita William R.
