A sufficient volume of sample will be taken and placed in a Nalgene® bag, an
equivalent plastic bag or container.

Collect approximately 1000 grams wet sample weight. This may not
always be possible due to vegetation conditions caused by drought etc.

Label the sample bag using an indelible marker with the location, date, and time
the sample was taken, field weight of sample and the SSTF#.

Note pertinent information in the field sampling logbook or equivalent, including
the location, date and time of sample, description of sample location, site
conditions, weight of sample, and any unusual circumstances encountered during
the sampling effort.
