Label all sample bottles with the locations ID, duplicate number (if more than one duplicate), sample date, test parameters, and preservative.

Use pens or markers that are permanent. Write directly on the bottle or use a label that will not fall off when the container gets wet.

Gather five clean prelabeled empty sample bottles (one for each type of analysis) into one gallon size ZipLock Gripper Zipper Freezer Bags.

Prepare one bag for each sampling location, plus triplet of QA/QC samples, plus two spare bags.

Load supplies and chemicals into the transportation boxes.
