Order kits from suppliers (www.environmentalexpress.com Part #M3015) or contact Paradigm for containers and sampling apparatus ($15/kit). For EACH location, you will be given:
3 tared 40 ml VOA vials (two empty with stir bars for low-level and one empty amber vial without stir bar for high-level analysis (if needed)
1 empty VOA vial (for moisture determination, labeled “evaporative loss”)
1 disposable soil coring tool, for nominal 5 gm sample collection
For each sampling location, fill the coring tool with the sample and push one core into each 40ml VOA vial (for a total of four per sample location). Clean and close each vial securely with a Teflon-lined cap.
(NOTE: if an MS/MSD is needed, use one additional kit for that location).
All VOA vials have been coded, pre-labeled and PRE-WEIGHED. DO NOT ADD A LABEL or any tape, or we will not be able to determine the sample weight.
Dispose of the coring tool. Do not re-use for any other locations.
Bring the samples on ice to the lab ASAP, but NOT TO EXCEED 48 Hours from time of sampling, otherwise holding times will be violated. The lab will freeze the samples upon log-in, and has up to a total of 14 days from sampling to analysis.
