Standard Practice for Sampling Liquids Using Bailers
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This practice covers the procedure for sampling stratified or un-stratified waters and liquid waste using bailers.
1.2 Three specific bailers are discussed in this practice. The bailers are the single and double check valve and differential pressure.
1.3 This standard does not cover all of the bailing devices available to the user. The bailers chosen for this practice are typical of those commercially available.
1.4 This practice should be used in conjunction with Guide D 4687, Practice D 5088, and Practice D 5283.
1.5 This standard does not purport to address all of the safety concerns, if any, 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.
Significance and Use
A bailer is a device for obtaining a sample from stratified or un-stratified waters and liquid wastes. The most common use of a bailer is for sampling ground water from single-screened wells (Fig. 1) and well clusters (see Guide D 4448
This practice is applicable to sampling water and liquid wastes. The sampling procedure will depend on sampling plan and the data quality objectives (DQOs) (Practice D 5792
Bailers may be used to purge ground water wells prior to sampling, but bailers are poor devices for removing large volumes of water.
Bailers may be used to sample waters and liquid wastes in underground and above ground tanks and surface impoundments. However, the design of the unit and associated piping should be well understood so that the bailer can access the desired compartment and depth. Any stratification of the liquid should be identified prior to sampling.
Note 1—Viscous liquids and suspended solids may interfere with a bailer’designed operation.
Bailers do not subject the sample to pressure extremes. Bailing does disturb the water column and may cause changes to the parameters to be measured (for example, turbidity, gases, etc.).
