VOCs

	Hold Time	Sample Volume	Container	Preservative
AQUEOUS
VOC	14 days	2x40 mL	VOC vials	HCl/Cool 4 ± 2°C
MA DEP VPH	14 days	2x40 mL	VOC vials	HCl/Cool 4 ± 2°C
ME GRO	14 days	2x40 mL	VOC vials	HCl/Cool 4 ± 2°C
GRO(8015)	14 days	2x40 mL	VOC vials	HCl/Cool 4 ± 2°C
Methane	14 days	2x40 mL	VOC vials	H2SO4/Cool 4 ± 2°C
1,4 Dioxane VOC	14 days	2x40 mL	VOC vials	Unpreserved /Cool 4 ± 2°C
Ethylene dibromide (EDB) and/or Dibromochloropropane (DBCP)	7 days	2x40 mL	VOC vials	Sodium Thiosulfate/Cool 4 ± 2°C
Samples should be collected in triplicate for any combination of VOC and GRO, MEGRO, or VPH. No headspace.
SOIL
VOC	14 days	2 oz	2 oz Glass
VOC Method 5035 **	14 days	5g	20 ml preweighed MEOH vial, 5 ml syringe, 4 oz glass jar
MA DEP VPH	28 days	5g	20 ml preweighed MEOH vial, 5 ml syringe, 4 oz glass jar
ME GRO	14 days	5g	20 ml preweighed MEOH vial, 5 ml syringe, 4 oz glass jar
GRO(8015)	14 days	5g	20 ml preweighed MEOH vial, 5 ml syringe, 4 oz glass jar
Organics must be collected in glass, not plastic! **VOC Method 5035 is a Federal Requirement. As a minimum in New England, samples need a soil jar, a MeOH vial, and duplicate Sodium Bisulfate Vials. The soil jar is for samples that contain calcareous material that effervesces in the MeOH. In the event Low Level is needed, Sodium Bisulfate vials are required. To date, MA and ME require MeOH and the Sodium Bisulfate vials.
