Properly contain all Investigation Derived Waste (IDW) generated during monitoring well installation, well development, well purging, and water sample collection activities. Contain all IDW in approved containers conforming to the requirements of the United States Department of Transportation. The containers must be labeled to include (at a minimum): project name, project location, date, container contents, and emergency contact name and phone number. Store IDW containers in a secure location on the project site, pending receipt of analytical results and eventual disposal. During field activities, record the number of IDW containers and their contents in the field log. Track the IDW containers until acceptance at the final disposal facility. Maintain proper disposal manifests in the project records. Section 5.8 provides additional information and procedures for IDW.
