vacuum pump, and 55 gallon drums. A loader will pick up ballast from the staging area and <br /> drive to the adjacent decon pad. While the steam is sprayed onto the ballast in the loader bucket, <br /> the loader will mix the ballast. The water will drain onto the decon pad, be vacuumed, and then <br /> transferred into 55-gallon drums. One water sample from a drum will be sampled and analyzed <br /> for TPH hydraulic oil and diesel for disposal. The "clean" ballast will be returned to the staging <br /> area and placed in a separate pile. <br /> 6.0 EQUIPMENT DECONTAMINATION <br /> Five-gallon buckets will be set up to decontaminate the hand auger and sampling equipment. <br /> Equipment is decontaminated by the following procedures: <br /> • Brush off loose dirt with a steel-bristle brush; <br /> • Equipment is washed with a non-phosphate detergent such as Alconox or Liquinox using <br /> plastic scrub brushes; <br /> • Equipment is rinsed with tap water; and <br /> • Equipment is rinsed with distilled water and allowed to air dry. <br /> Decontamination (decon) water will be transferred into a 55-gallon drum for storage prior to <br /> disposal. A Tetra Tech label will be placed on the drum with the date water entered on the drum. <br /> 6.0 FIELD NOTES <br /> Tetra Tech will observe and record information on daily field sheets in a chronological manner. <br /> The observations will include: field conditions, equipment utilized, subcontractors and visitors <br /> on-site, excavation areas, sampling locations, samples collected, depth to water, noticeable soil <br /> discoloration and odor, area of stockpiles, and other pertinent items.
