* Water samples with residual chloride present must be preserved with 10% sodium thiosulfate. Please contact the laboratory for information on how much to add.

NOTES:

All information within this list is based on minimal requirements of standard methods; some samples should be analyzed as soon as possible after sample collection.
If both BTEX/TpgH and extractable analysis (eg. TEH, PAH etc.) is needed for water, samples must be submitted in separate containers for each analysis.
To determine how much sample is required for multiple analyses or for packages, add up minimum sample size requirements and use the bottle that will ensure that you have at least the minimum sample volume required for analysis. If you require assistance in determining minimum sample volume, please contact your customer service representative.
