STOCKTON, CA <br /> Vicki, <br /> The results of the Third Quarter of 2006 Monitoring for MW 3 (down gradient well) at the H&H <br /> Engineering and Construction are back. Greg Stahl at Ground Zero is working on the report,. <br /> -but here is the short version. <br /> None of the target compounds (TPHg, or BTEX) were detected. This is is the second <br /> consecutive non detect for Benzene in MW-3 and the other target compounds have not been <br /> detected in MW-3 for over a year now. <br /> I do not know if you have had a chance to look at the Human Health Risk Screening.Evaluation <br /> for Vapor Intrusion of Groundwater that Ground Zero Submitted for the site in June 2005. The <br /> evaluation concluded the average concentrations of residual gasoline and benzene in the <br /> groundwater do not exceed the screening levels for vapor intrusion concerns for commercial or <br /> residential use. <br /> The results of the 3rd quarter monitoring strongly indicate the plume has stabilized and the <br /> results of the Vapor Intrusion Screen indicate the potential hazard from vapor intrusion is <br /> below the screening. levels. The concerns the EHD identified in a letter dated April 4, 2006 <br /> have been addressed and we believe the site is ready for closure. i <br /> i <br /> Do you agree? <br /> Thanks, i <br /> Jan Thompson <br /> Wilbur-Ellis Company <br /> 541 369-3624 <br /> C <br /> 9/7/2006 C <br />
