APPENDIX E<br />

soil piles will be bermed to prevent runoff. At the end of the work shift and at the end of the excavation<br />

activity, until waste disposition is determined, the soil stockpiles must be secured to prevent tampering<br />

and potential runoff.<br />

Containers of soil cuttings will be identified with a particular boring, well, or pit. However, to minimize<br />

the number of drums generated during an investigation, it may be necessary to mix soils from several<br />

sources, provided those sources are from the same general location. Documentation will be maintained<br />

to identify the source of the soils (including depths) containerized in a particular drum. The<br />

documentation will specify which samples sent for laboratory analysis correspond to the drum contents.<br />

The description of the waste/soil, boring location, and general observations will also be noted in the field<br />

log book. The logbook control number and page where the drum waste is described will be noted in a<br />

dedicated drum log sheet.<br />

4.1.2 Drilling Mud<br />

Drilling muds are defined as those materials/additives required during the reaming of boreholes to maintain<br />

the integrity of the borehole wall and/or to expedite the drilling of the borehole. Though generally fluid in<br />

nature, these muds will be referred to as solids in this document. Drilling mud will be isolated from soil<br />

cuttings. In limited instances, it may be acceptable to combine drilling mud with soil cuttings to reduce the<br />

number of drums. In either case, careful documentation will be made in the field log book and the drum log<br />

sheet indicating which wells the drilling mud came from. If samples of the mud are collected and sent for<br />

analysis, documentation will indicate which samples correspond to the contents of the drum and adequate<br />

information will be included in the drum log sheet.<br />

4.1.3 Purge and Development Water<br />

Monitoring wells will be purged during development and prior to sampling as described in the projectspecific<br />

addenda, the FSP (Appendix A of the BWP), and the standard operating procedures (Appendix B<br />

of the BWP).<br />

Well purge and development water will be containerized separately from soil cuttings, drilling mud, PPE,<br />

and other solid waste. Documentation will be maintained to correlate representative environmental or<br />

drum samples sent for analyses with waste contained in a particular drum. It will be acceptable to mix<br />

water from different wells, provided that proper documentation is maintained and that non-hazardous<br />

materials are not mixed with hazardous materials.<br />

4.1.4 Decontamination Fluids<br />

Equipment will be decontaminated as described in the project-specific addenda, the FSP (Appendix A of<br />

the BWP), and the standard operating procedures (Appendix B of the BWP). Decontamination water,<br />

which includes decontamination fluids or solvents such as acetone or nitric acid, will not be<br />

containerized with well purge/development water because of their different waste classifications. The<br />

former liquid waste will be collected and disposed of, as necessary, in a drum dedicated for this type of<br />

waste. Excess sample preservatives must be stored separately from decontamination fluids and disposed<br />

of properly. Notations on preservative type will be made in the log book and on the drum.<br />
