1.3 This practice provides instructions on the use of these samplers.

1.4 This practice does not address sampling devices for collecting ground water.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
