During the course of a Site <br /> visit on April of 2000 conducted by San Joaquin County Environmental Health Division <br /> (SICEM), it was discovered that four dry wells in the evaporation pond were not permitted. <br /> The possibility exists that an unknown substance may have impacted the storm water holding <br /> pond located on the southeastern portion of the subject Property.

The baring will be advanced to a maximum depth of 6-8 inches from the <br /> bottom surface. The laboratory will then be instructed to remove their sample extraction <br /> from the bottom portion of the sampling tube If water is encountered in a dry-well, the water <br /> will be removed using a bailer before the sample is collected. <br /> • The soil sample will be collected using a butterfly vale spoon sampler driven in advance of a <br /> 10-pound hand-operated hammer. AMES staff will remove the tube from the sampler for <br /> analysis. The ends of the soil-filled sample tube will be sealed with Teflon-lined caps and <br /> duct taped. The soil sample will be labeled then stored in a chest cooled with ice and <br /> transported to a state-certified analytical laboratory for analysis under chain-of-ustody. <br /> • A state-certified laboratory will be used to perform chemical analyses on the soil sample <br /> collected. The sample will be analyzed for total petroleum hydrocarbons (TPH) for <br /> 1 of 2 <br /> ASSET MANAGEMENT& ENVIRONMENTAL SERVICES <br /> 62 Avignon euaFoothill <br /> hRanch, 948Fax <br /> 9} 586-7315 <br /> -mameCeairt web page htio .wm. ahlnK.net/- r-*s <br />
