Full title and description

Standard Practice for Sampling of Liquids in Waste Management Activities Using a Peristaltic Pump (ASTM D7353-21). This practice provides field-oriented procedures for using a peristaltic pump to collect liquid samples from drums, tanks, monitoring and waste wells (including small-diameter wells) and from multiple depths, for a wide range of fluids including high-viscosity, aggressive/corrosive, high-purity, and abrasive fluids.

Abstract

ASTM D7353-21 describes methods to determine sample depth, set up and connect a peristaltic pump sampling train, and collect representative liquid samples for laboratory analysis. The practice highlights advantages of peristaltic pumps (isolation of fluid from pump, disposable tubing, self-priming) and notes limitations such as potential degassing and loss of volatile organic compounds (VOCs) when a vacuum is used. It is intended for field personnel; it does not specify or endorse particular pump models.

Scope

This practice covers use of peristaltic pumps to sample liquids from multiple depths in drums, tanks, monitoring and waste wells (including small-diameter wells). It addresses determining sample depth, pump setup and connections, and sample collection and handling for subsequent analysis. The practice is applicable to a broad range of fluids (high-viscosity, corrosive, high-purity, abrasive) but does not provide manufacturer-specific pump operation instructions or purchase recommendations. It also notes that peristaltic-pump sampling may cause degassing and loss of VOCs, and thus should not be used when precise VOC/dissolved gas quantitation is required.

Key topics and requirements

• Applicability: sampling from drums, tanks, monitoring and waste wells including small-diameter wells.
• Determination of sample depth and procedures for sampling at multiple depths.
• Pump setup and connections: recommended field practices for connecting intake/discharge tubing and isolating sample stream.
• Material compatibility and selection of tubing (disposable tubing, easy replacement, isolation benefits).
• Quality considerations: potential for degassing and VOC loss when vacuum is used; when to avoid peristaltic pumps (for precise VOC/dissolved-gas analysis).
• References to related sampling design, representativeness, heterogeneity, and data quality objectives (DQOs) in companion ASTM practices and guides.

Typical use and users

Used by environmental and waste-management field sampling personnel, environmental consultants, site remediators, industrial hygienists, regulatory compliance teams, and laboratories that receive field-collected liquid samples. Typical applications include site characterization, monitoring-well sampling, waste drum/tank sampling, and field screening where pump isolation is important but precise VOC quantitation is not required. The practice is developed under ASTM Committee D34 (Waste Management).
