ASTM D5088-15a

1.1This practice covers the decontamination of field equipment used in the sampling of soils, soil gas, sludges, surface water, and groundwater at waste sites which are to undergo both physical and chemical analyses.

1.2This practice is applicable only at sites where chemical (organic and inorganic) wastes are a concern. It is not intended for use at radiological, mixed (chemical and radiological), or biohazard sites. This practice does not address regulatory requirements for the handling, labeling, shipping, or storing of wastes or samples.

1.3Practices are included for the decontamination of equipment which comes into contact with the sample matrix (sample contacting equipment) and for ancillary equipment that has not contacted the portion of sample to be analyzed (non-sample contacting equipment), but which must be cleaned to avoid spreading of contamination.

1.4This practice is intended for use when field equipment used for sampling will be decontaminated in the field or returned from the field. Information on the construction of field decontamination facilities and non-sample contacting equipment decontamination is also provided.

1.5This practice is based on commonly recognized methods by which equipment may be decontaminated. The practices described for sample contacting equipment are commonly prescribed. Background studies are included in the References at the end of this standard (12345). The user is reminded of the importance of proper decontamination planning to minimize the amount of decontamination wastes generated and to reduce or eliminate the use of cleaning agents that are themselves hazardous. Quality Assurance/Quality Control (QA/QC) samples that document decontamination effectiveness can be used to modify or enhance decontamination techniques. Decontamination at radiologically contaminated sites should refer to Practice D5608.

1.6This practice is applicable to most conventional sampling equipment constructed of metallic and synthetic materials. The manufacturer of a specific sampling apparatus should be contacted or the manufacturer’s manuals reviewed if there is concern regarding the reactivity of a decontamination rinsing agent or the temperatures that could affect the equipment. Plastic components and gasket materials could be damaged by some of the stronger reagents or high temperatures.

1.7The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.8This practice offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.

1.9This standard does not purport to address the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
