Subsequently,PHS/EHD agreed to the requests to extend this deadline to November 20, 1999,and then to January 7,2000. In a telephone conversation with BSK staff on January 25, 2000, PHS/EHD agreed to performance of the proposed work starting on February 7, 2000. In a telephone conversation on January 28, 2000, BSK informed PHS/EHD that Mrs.Wanda Veldstra, the current resident at the property, refused to give access to the site so the work could not be performed. In a site visit on March 7,2000, members of this office informed Wanda and Albert Veldstra that they would be named as a responsible party since PHS/EHD has confirmed they are the property owners,and that an official Notification of Responsibility (NOR)would be sent to them. PHS/EHD staff explained to Wanda and Albert the purpose of the proposed work was to define the extent of the contamination plume in soil and groundwater and that corrective action would be required. PHS/EHD emphasized the urgency of the investigation and the cleanup of this site because of the close proximity of the domestic well to the plume of contamination which contains benzene,a known carcinogen. The Veldstras were shown a table of the results of the groundwater samples collected from the monitoring wells (MW),and the potential health hazard if the domestic well became impacted was discussed. PHS/EHD informed the Veldstras that they would be included in all future correspondence. In a telephone conversation on March 8,2000 with Mr.Raymond Greer,he expressed his discontent with the additional work PHS/EHD has directed and questioned the validity of the analytical results of the groundwater samples documented in the reports. PHS/EHD explained to Mr. Greer the legitimacy of the analytical results documented in the reports (Soil&Groundwater Investigation Interim Report dated May 18, 1999,Monitoring Report Second Quarter 1999 dated July 16, 1999,Status Report Tbird Quarter 1999 dated November 5, 1999,and Status Report Fourth Quarter 1999 dated February 8,2000 prepared by BSK) since the same petroleum hydrocarbon constituents have been consistently detected in the MW groundwater samples. PHS/EHD explained to Mr. Greer the fluctuation in the concentrations of the hydrocarbons constituents detected in the MW samples can be attributed to many factors such as groundwater movements and the continuously releasing source in the vadose zone leaching into groundwater. PHS/EHD informed Mr. Greer the significance of the high level and A Division of San Joaquin County Health Care Services
