Soil Sampling
General guidelines Field screening Soil analytical sample collection Soil sampling equipment
Excavated Soil Sample Collection Guide
By Volume (cubic yards)
Number of Screening Samples
Associated Number of
Laboratory Samples
0-10 5 111-50 5 251-100 1 per 10 CY 3
More than 100
1 per 10 cy, or as the
department determines necessary
3 samples, plus one (1) sample for each additional 200 cubic yards, or portion thereof or as the department determines necessary.
Previous requirement: Field screening 1 per 10 CY. For untreated stockpile 2 lab samples for 0-50 CY, plus 1 lab sample per additional 50 CY or portion thereof. For treated stockpile 5 lab samples for 101-500 CY, 7 lab for 501-1000 CY, 10 lab for 1001-2000 CY, and 10+1 lab per 500 CY or portion thereof for 2000+ CY (or as the department determines necessary)

Number of Screening Samples
Associated Number of Laboratory
Samples
0-50 5 1 51-124 5 2
125-250 1 per 25 sq ft 2
> 250 10 plus 1 per
additional 100 ft2, or as the department
determines necessary
2 samples, plus one sample for each additional 250 square feet, or portion thereof; or as the department determines necessary.
Excavation sidewalls
For each excavation sidewall, 1 per 10
linear feet, or portion thereof, with field screening sample
collection focused on soil horizons
demonstrated as likely to be
contaminated.
Minimum 1 per 20 linear feet, or portion thereof at the highest field screening reading in all soil strata (i.e. a 20’x20’ excavation [80 linear feet total] would require 4 analytical samples. A 4’x4’ excavation [16 linear feet total] would require 1 analytical sample.)
Previous requirement: At least 1 field screening for every 100 sq ft of excavation bottom. For sidewalls, assess where contamination is most likely present. 2 lab samples for 0-250 sq ft + 1 lab sample for each additional 250 sq ft or portion thereof.
Groundwater Sampling General groundwater sampling

collection (including no purge and passive groundwater sampling for VOCs)

Previous requirement: For any sample, if the sum of the hydrocarbon fractions (i.e. DRO, GRO, RRO) are greater than 500 mg/kg then PAH analysis was required. The other red highlighted areas were only required on a site specific basis previously.
7 For each source area, PAH analysis must be performed on a percentage on the samples with the highest DRO, RRO, GRO, concentrations to determine if PAHs are contaminants of concern. In general 10% are recommended for site characterization. If PAH concentrations are less than applicable cleanup levels, further PAH analysis is generally not required. PAHs should be sampled in groundwater if soil sample concentrations are above applicable cleanup levels and groundwater sampling is required.

Documented affects on VOCs
http://water.usgs.gov/owq/FieldManual/Chapter2/Chapter2_V2uncompressed.pdfSection 2.1.2 A, page 46, loss of dissolved gasses due to vacuum. ASTM D7353- “Peristaltic pumps use a vacuum to transport the samples. This vacuum
may cause some degassing and loss of volatile organic compounds (VOCs) from the sample.”
http://www.epa.gov/region09/qa/pdfs/rcra_gwm92.pdf“Recent research focusing on the comparison of different types of ground-water
sampling equipment demonstrates that significant loss of volatile organic compounds may occur when bailers are used to sample ground water (Pearsall and Eckhardt, 1987; Yeskis et al., 1988; Tai et al., 1991; Pohlmann et al., undated).”
http://www.dnr.state.wi.us/org/water/dwg/gw/dsh_3a.htmAccording to a study conducted by Barker and Dickhout (1988) to evaluate the loss of volatile
organic analytes from groundwater ….”the peristaltic pump provided samples with a significant negative bias (9 to 33 percent lower) relative to the bladder pump and inertial-lift pump methods.”
http://www.state.nj.us/dep//srp/guidance/lowflow/lowflow05.htmRegarding Bailers- …[VOC] …results may be biased low (due to aeration) and metals
analytical results may be biased high (due to turbidity).
