Field Sampling Methods

To perform analytical tests, field samples must be collected according to standard protocols. This section

defines the field sampling methods that apply to this ESTCP DP. These protocols describe appropriate

procedures to collect field samples for the purpose of (1) determining physical characteristics and (2)

measuring chemical constituents. The field protocols for this study were selected to ensure that

sampling procedures meet the requirements for the intended use of the data. Field sampling activities will

be led by Dr. Dennis Smithenry. All general field information, including field location, field activities,

type of equipment, and weather, will be recorded on the Field Daily Log Form, and maintained in a

paginated and bound field logbook (see Section A.2.7.3). Field SOPs can be found in Attachment 2.

The sampling area will be scanned for radioactivity by Tetra Tech ECI field personnel prior to the survey.

This scanning will be conducted at HPS due to the historical disposal of radium dials in the landfill in

Parcel E. The scanners will notify the HSO, and Radiation Safety Officer (RSO) of any samples with

greater than two sigma background readings. The HASP describes the procedures for sample segregation

and disposal, decontamination, and the procedures for the release of materials for unrestricted use. The

Tetra Tech ECI project HASP details the scanning procedures.
