Before commencing field work, the HSP will be reviewed by CDIM personnel at the Site. Since minimal exposure to personnel is expected during the sampling process, required personal protective equipment will be Level D, which is described as a work uniform affording minimal protection, and used for nuisance contamination only. 4.6 Decontamination Single-use items (e.g., gloves, sampling scoops, direct push liners)will be utilized to the extent possible to avoid cross-contamination between samples. In addition, the driller will clean drilling and other reusable downhole equipment between borings. 4.7Investigation Derived Waste All investigation derived waste, including soil cuttings, will be contained in Department of Transportation- approved 55-gallon drums.
