APPENDIX A<br />

4.3.3 Ambient Field Blank<br />

An ambient blank is Type II Reagent Grade Water that is poured into a sample container at a sampling<br />

site. It will be handled like a sample and transported to a laboratory for analysis.<br />

4.3.4 Field Duplicate<br />

A field duplicate is an additional sample collected independently at a sampling location so that two sets<br />

of samples are collected during a single act of sampling. Field duplicates will be identified such that<br />

laboratory personnel are unable to distinguish them from normal field samples unless otherwise specified<br />

in the project-specific plan.<br />

4.3.5 Equipment Blank<br />

An equipment blank is Type II Reagent Grade Water that is poured into or pumped through the sampling<br />

device, transferred to a sample bottle, and transported to a laboratory for analysis.<br />

4.4 Equipment Decontamination<br />

The methods for the proper decontamination of all field sampling equipment are detailed in Appendix B,<br />

SOP B1.10. Procedures differ according to the type and the intended use of the sampling equipment, as<br />

well as guidelines specified by government agencies. All equipment that may directly or indirectly<br />

contact samples will be decontaminated in a designated decontamination area. This includes casing, drill<br />

bits, auger flights, the portions of drill rigs that stand above boreholes, sampling devices, and<br />

instruments, such as slugs and sounders, and buckets of excavators. Care will be taken to prevent the<br />

sample device from coming into contact with potentially contaminating substances, such as tape, oil,<br />

engine exhaust, corroded surfaces, and dirt.<br />

4.5 Field Measurements<br />

This section identifies the elements to be considered during field measurements and outlines the SOPs to<br />

be used when collecting specific types of data. Generally, field measurements include, but are not<br />

limited to: temperature, pH, oxidation reduction potential, conductivity, turbidity, dissolved oxygen,<br />

width, depth, and flow rate of streams; water levels; and well depth. Field screening techniques such as<br />

soil gas, field gas chromatography, and x-ray fluorescence also fall under this category. The Base-Wide<br />

Health and Safety Plan (BWHSP), Appendix F of this BWP, project-specific addenda, and the<br />

Contractor‟s Site-Specific Safety and Health Plan (SSHP) will be used as guidance when measurements<br />

are made for health and safety monitoring.<br />

The following elements should be considered when developing project-specific addenda:<br />

Parameters to be measured in the field and the type of equipment to be used<br />

Intended use of these measurements<br />

Rationale for selecting a particular equipment or technique<br />

Detection limits and QA/QC requirements for each piece of equipment<br />

Calibration and preventive maintenance requirements<br />
