|Significance and Use|
5.1This practice is intended to assist field personnel in obtaining samples from tanks for laboratory analysis.

Incorrect sampling can invalidate resulting data.
5.2This practice provides guidance in choosing the sampling technique and equipment suitable for specific situations. It is recommended that this guide be used as a supplement to a written field sampling plan.
5.3The procedures for sampling tanks using a COLIWASA, liquid profiler sampler, bacon bomb sampler, and peristaltic pump and tubing are delineated.
