It curr two pump islands three UST's (one diesel). Superseded UST's may also remain on the property. This property is listed on San Joaquin County's Underground Storage Tank's and Site mitigation information list. It appears that they did have gas contamination on site. County file information indicates there were repairs performed to the Diesel tank piping on 8/14/86. ETS Environmental was contracted with to drill six borings and samples were taken at 5', 10', 15' and composited. Groundwater was encountered at 10'. They did find limited heavily weathered gasoline present near the surface in the vicinity of boring 6 below reportable limits. According to the chain of custody, analysis did not include BTX for Borings 1-5 at depths of 5, 10,1.5, feet.The county did not agree with the composite procedure. A letter from the County indicated that the composited samples were unacceptable and questioned the lab methodology used to determine a small amount of weathered hvdrocarbon contamination found in boring n6. The County also questioned .rhy soil samples were not collected at 5' in boring ri6. Diane Hinson requested additional sampling under the waste oil tank. She requested a 30o angle at 4' and 6'. There were limited contaminates found beneath the waste oil tank and the Consultant argued that the contamination posed no threat and that in-situ remediation would not be cost effective. The County required further investigation and they included this parcel in the Pilot Program, October 3, 1989. Therefore, should we decide to purchase this property, we would first have to wait until the owner addresses the concerns of the county. When the investigation is complete evaluate the data and determine if we want to purchase the property based on the results of the investigation.
