was made to collect samples from as great a depth as possible, however, the <br /> presence of hardpan prevented a thorough evaluation of subsurface contamination <br /> Figure 3 - Soil Vapor Survey Sampling Location Plan of Canonie's report <br /> identifies the location of each sampling point <br /> On September 28, 1992, a site assessment will conducted at the subject property <br /> to assist in defining the lateral and vertical extent of contamination Because <br /> groundwater is not expected to be encountered at depths of less than 100 feet, <br /> the presence of groundwater contamination will not be evaluated unless site <br /> conditions warrant it In any event, monitoring wells will be installed for the <br /> purpose of future in-situ remediation by vapor extraction Figure 3 in Canonie's <br /> report identifies the proposed boring and monitoring well locations <br /> Upon completion of field activities, a report documenting the findings of the <br /> site assessment will be forwarded for your review If you have any questions <br /> regarding this matter, please do not hesitate to contact me at (206) 286-4495 <br /> If I am not available, Kevin Murphy may be able to answer any questions that you <br /> may have <br /> Sincerely, <br /> 14 CcS4'2C, 't <br /> Anastasia E Duarte <br /> Environmental Toxicologist <br /> cc Mr Edwin Crawford <br /> California Regional Water Quality Control Board <br /> Ms Gina Morrison <br /> Canonie Environmental <br /> iaed/sep92/4049 lt4 <br />
