Equipment Decontamination SOP grade solvent,typically acetone, allow the solvent to evaporate, and then rinse the equipment with deionized water. If acetone is a constituent of concern, substitute methanol as the rinse agent. Collect solvent waste in a separate container and allow to evaporate. 4. Rinse the equipment with copious quantities of distilled or deionizedwater. 5. Allow the equipment to air dry on a clean surface or rack elevated at least two feet above ground. Notes: If a particular contaminant fraction is not present at the site, the sampling equipment decontamination procedure specified above may be modified for site specificity. For example, the solvent rinse may be eliminated if organics are not of concern at a site. Modifications to the standard procedure shall be documented in the site-specific Work Plan or subsequent report. Post-Decontamination Procedures At the completion of the decontamination activities, all fluids and solid waste shall be containerized and managed in accordance with Waste Management SOP. Document decontamination activities in the field logbook(see Fieldwork Documentation SOP). After equipment has been decontaminated, recontamination should be prevented through the handling of equipment only by personnel wearing clean gloves, as well as by moving the equipment away (preferably upwind) from the decontamination area. If the equipment will not be immediately reused, store the equipment in an area free of contaminants. 10.0 Data and Records Management: To finalize fieldwork documentation in accordance with Antea Group's document control and retention policies: • Recheck all data inputs to prevent errors. • If data were generated from multiple/different sample locations (borings, wells, etc.) at the same site, use appropriate file naming conventions to distinguish one file from another(e.g., year month day-what, 20200408_MW-01_MW-15). • Ensure that any repair work needed, issues to be resolved, and/or any uncompleted fieldwork are noted in the fieldwork documentation and reported to the PM. • During the field effort, send photos of field forms to the PM for review at the end of each day(ultimately at the discretion of the PM). Scan and upload copies of field notes/forms and all health and safety documents (completed JSA and HASP) to the designated project folder in SharePoint in Teams (e.g., "Field Notes and Data/Boring Logs")within 48-72 hours after project completion,unless instructed differently by the PM. 11.0 Quality Control: • All data, observations, calculations must be documented in the field logbook, field forms, and/or any electronic data recording devices (field computers, digital cameras, etc.).
