The soil classification and description, grain size, size grading, subordinate constituents, color, density, moisture content, and organic vapor readings, will be recorded on a field boring log. Soil samples will be examined in the field for observable signs of petroleum hydrocarbons and screened for hydrocarbon vapors using a photoionization detector. Soil samples will be submitted under chain of custody procedures to TestAmerica Laboratories for analysis. Soil generated from the borings will be placed in 55-gallon drums and sealed upon completion of the work activities. The soil cuttings will remain in the drums on site until they can be properly disposed.
