1.1 This practice describes general and specific procedures, methods and considerations to be used and observed when cleaning and decontaminating sampling equipment during the course of investigations at waste sites. 1.2 This practice is intended to be followed when field decontaminating sampling equipment that will be reused in the field or returned from the field. 1.3 When the project work plan and proposed analytical methodology permit, it is preferable to use reagents that will not generate hazardous waste. The basic decontamination procedure detail here consists of cleaning the equipment with phosphate- free laboratory detergent and tap water. Management of Investigative Derived Waste (IDW) generated during the decontamination operations of a field investigation should be specified in the investigations project plan and in accordance with all applicable or relevant and appropriate requirements. 1.4 Guidance is provided for construction of decontamination pads for larger equipment.
This practice discusses procedures for decontaminating and cleaning sample equipment used at waste sites. Guidance is given for the reagents that should be used and for construction of decontamination pads for larger equipment. Specific procedures are provided for decontaminating equipment used to collect samples for both trace organic or inorganic constituent analyses and classical parameters.
