Recent information which has come to our attention leads to some modification of the protocol sug-
gested for volatiles in soil and sediment.
1. Use 30 cc of water with mercuric chloride preservative for tared voa vial.
2. Very carefully and quickly transfer a small aliquot of soil (1 gm) from a core sample to the
prepared VOA vial.
3. If analysis is not to be performed in the field using the headspace technique, return the filled
sample vials to the laboratory inverted. This will help preserve volatiles from being lost thru the
septum.
4. The rational for this procedure is that large soil samples will require several volumes of water
to leach out higl], level organics. This is based on work of John Wilson et al at$he Ada Labs.
