Each sample bottle must be correctly labeled with the station identification number, date, time, and sample designation. Sample designation is established by the laboratory. Laboratory codes that are added or deleted from the analytical schedule requested should be recorded on the ASR forms that accompany the samples--not on the sample bottles.

1. Label each bottle with a permanent, waterproof marker, or use preprinted labels that will remain securely attached to the bottles, even if they become wet.
2. Write legibly and include as a minimum the following information:

Station identification number.

  Date and time of sample collection.
  Sample designation code (Appendixes A5-A through A5-C).


A bottle with an unreadable label or no label is a wasted sample.
