Sample Bags
Preparing sample bags before entering the field has proven to be the best way to
avoid collection errors.
Keeping it simple avoids mistakes that can, in the worst case, require an
additional field trip. Having enough sample bags pre numbered and organized
prior to collection avoids duplicate and skipped sample numbers. Writing a
number on a map or marking the sample number on a GPS unit is far easier than
writing on a bag while checking the map for a arbitrary sample number. Let the
collector assign the bag number to the collection point. This provides the collector
the freedom to collect in the most efficient manner and avoid mistakes.

Use Ziploc or other resealable plastic bags.
Using a Sharpie permanent
marker, write the number on
the upper right hand corner of
both sides of the bag.

Thousands of sample bags can be prepared and organized in this manner.
In the Field
1. Open each group of bags as needed securing the ten lose bags in a clip board.
2. As each sample is collected check each bag number and record it on the field
map.
3. Many GPS systems will provide a sequential numbering "mark" function that can
be used to record the bag number.
