SOIL GAS SAMPLING PROCEDURE

L Probe Placement

A) A clean probe (pipe) is removed from the "clean" storage tube on top of the van.

B) The soil gas probe is placed in the jaws of hydrauUc pusher/puller mechanism.

C) A sampling point is put on the bottom of the probe.

D) The hydraulic pushing mechanism is used to push the probe mto the ground.

E) If the pusher mechanism will not push the probe into the ground a sufficient

depth for sampling, the hydrauhc hammer is used to pound the probe into the

ground.

n. Sample Extraction

A) An adaptor (Figure 1) is put onto the top of the soil gas probe.

B) The vacuum pump is hooked onto the adaptor.

C) The vacuum pump is turned on and used to evacuate soil gas.

D) Evacuation will be at least 30 seconds but never more than 5 minutes for

samples having evacuation pressures less than 15 inches of mercury.

Evacuation times will be at least 1 minute, but no more than 5 minutes for

probes reading greater than 15 inches of mercury.

E) Gauges on the vacuum pump are checked for inches of mercury.

1. Gauge must read at least 2 inches of mercury less than

maximum vacuum to be extracting sufficient soil gas to collect

a vahd sample.

in. Sample Collection

A) With vacuum pump running, a hypodermic syringe needle is inserted

through the silicone rubber and down into the metal tubing of adaptor

T r a c e r Resea rch C o r p o r a c i o n

UL

(Figure 1).

B) Gas samples should only contact metal surfaces and never contact

potentially sorbing materials (i.e., mbing, hose, pump diaphragm).

C) The syringe is purged with soil gas then, without removing syringe needle

from adaptor, a 2-10 mL soil gas sample is collected.

D) The syringe and needle are removed from the adaptor and the end of the

needle is capped.

E) If necessary, a second 10 mL sample is collected using the same

procedure.

IV. Deactivation of Sampling Apparatus

A) The vacuum pump is turned off and unhooked from the adaptor.

B) The adaptor is removed and stored with equipment to be cleaned.

C) Using the hydrauhc puller mechanism, the probe is removed from the ground.

D) The probe is stored in the "dirty" probe tube on top of the van.

E) The probe hole is backfilled, if required.

V. Log Book and U.S. EPA Field Sheet Notations For Sampling (Figures 2A-2D)

consultation with TRC persoimel) prior to start of job.

B) Remaining sample locations may be detennined by:

1) CUent

a) Entire job sampling locations set up on grid system.

b) Client decides location of remaining sample

locations based on results of initial study, or

2) Client and TRC Personnel

a) Client and TRC persoimel decide location of

remaining sample locations based on results of

initial sample locations.

ANALYTICAL PROCEDURES

I. Varian 3300 Gas Chromatograph

A) Equipped with Electron Capture Detectors (ECD), Flame Ionization

Detectors (FID), Photo Ionization Detectors (PID) and/or Thermal

Conductivity (TC) Detectors.

B) The chromatographic column used by TRC for the analysis of halocarbons

is a 1/8" diameter packed column containing Alltech OV-101. This nicely

separates most of the tri-chloro and tetra-chloro compoimds that are

encountered in soil gas investigations. The di-chloro compounds tend to elute

ahead of the tri-chloro and tetra-chloro compounds, thus creating no

interference. In the event that assurance of the identity of a compound in

any particular sample is needed, it will be analyzed on a SP-1000 column

after the OV-101 analysis.

n. Two Spectra Physics SP4270 Computing Integrators.

The integrators are used to plot the chromatogram and measure the size of

the chromatographic peaks. The integrators compute and record the area of

each peak. The peak areas are used directly in calculation of contaminant

concentration.

m. Chemical Standards From ChemServices, Inc. of Westchester, Pennsylvania.

A) TRC uses analytical standards that are preanalyzed, of certified purities

and lot numbered for quality control assurance. Each vial is marked with

an expiration date. All analytical standards are the highest grade available.

Certified purities are typically 99%.

B) The Quality Assurance procedures used by ChemService were described

by the Laboratory Supervisor, Dr. Lyle Phipher:

T r a c e r R e s e a r c h C o r p o r a c i o n

1) The primary measurement equipment at ChemServices, the

analytical balance, is serviced by the Mettler Balance Company

on an annual basis and recalibrated with NBS traceable weights.

2) All chemicals purchased for use in making the standards are

checked for purity by means of gas chromatography using a

thermal conductivity detector. Their chemicals are purified as

needed.

3) The information on the purification and analysis of the

standards is made available upon request for any item they ship

when the item is identified by lot number. All standards and

chemicals are shipped with their lot numbers printed on them.

The standards used by TRC are made up in a two step dilution

ot the pure chemical furnished by ChemServices.

rv. Analytical Supplies

1. Sufficient 2 and 10 cc glass and Hamilton syringes so that none have to

be reused without first being cleaned.

2. Disposable lab supplies, where appropriate.

3. Glassware to prepare aqueous standards.

4. Miscellaneous laboratory suppUes.

QA/QC PROCEDURES

L Standards

A) A fresh standard is prepared each day. The standards are made by serial

dilution.

1) First, a stock solution containing the standard in methanol

is prepared at TRC offices in Tucson. The stock solution is

prepared by pipetting the pure chemical into 250 mL of

methanol in a volumetric flask at room temperature. The

absolute mass is determined from the product of volume and

density calculated at room temperature. Hamilton microUter

syringes, with a manufacturer's stated accuracy of + or - 1%,

are used for pipetting. Informafion on.density is obtained from

the CRC Handbook of Physics and Chemistry. Once the stock

solution is prepared, typically in concentrafion range of 50-1000

mg/L, a working standard is prepared in water each day. The

solute in the stock solution has a strong affinity to remain in

methanol so there is no need to refrigerate the stock solution.

Additionally, the solute tends not to biodegrade or volatilize out

of the stock solution.

2) The working standards are prepared in 40 mL VOA sepmm

vials by diluting the appropriate ug/L quantity of the standard

solution into 40 mL of water.

B) The standard water is analyzed for contamination before making the

aqueous standard each day.

C) The aqueous standard is prepared in a clean vial using the same syringe

each day. The syringe should only be used for that standard.

T r a c e r Research C o r p o r a c i o n

D) Final dilution of the calibration standards are made in water in a VOA

vial having a Teflon coated septum cap instead of in a volumetric flask in

order to have the standard in a container with no air exposure. The VOA

bottie pennits mixing of the standard solution and subsequent syringe

sampUng all day long without opening the bottle or exposing it to air. The

measurement uncertainty inherent in the use of a VOA bottle instead of a

volumetric flask is approximately -t- or - 1%.

E) The aqueous standard will contain the compounds of interest in the range

of 5 to 100 ug/L depending on the detectability of the individual components.

The standard will be analyzed at least three times at the begirming of each

day to determine the mean response factor (RF) for each component (Figure

3). The standard wiU be injected again after every fifth sample to check

detector response and chromatographic performance of the instnunent

throughout the day.

F) The RF allows conversion of peak areas into concentrations for the

contaminants of interest. The RF used is changed if the standard response

varies 25%. If the standard injections vary by more than 25% the standard

injections are repeated. If the mean of the two standard injections represents

greater than 25% difference then a third standard is injected and a new RF

is calculated from the three standard injections. A new data sheet is started

with the new RF's and calibration data.

% difference = A area - B area

A area

Where ; A = mean peak area of standard injection from first caUbration

B = peak area of subsequent standard injection

G) The low ug/L aqueous standards that are made fresh daily need not be

refrigerated during the day because they do not change significantly in a 24

T r a c e r Reaearch C o r p o r a c i o n

hour period. On numerous occasions the unrefrigerated 24 hour old

standards have been compared with fresh standards and no difference has

been measurable. If the standards were made at high ppm levels in water,

the problem of volatilization would probably be more pronounced in the

absence of refrigeration.

H) Primary standards are kept in the hotel room when on a project.

I) A client may provide analytical standards for additional calibration and

verification.

n. Syringe Blanks

A) Each uL syringe is blanked before use.

B) 2 cc (glass) syringes wiU each be blanked if ambient air concentrations are

elevated (greater than or equal to 0.01 ug/L) for components of interest.

C) If ambient air concentrations are < 0.01 ug/L for components of interest,

a representative sample of at least two syringes are blanked at the beginmng

of each day. If representative syringes have no detectable contamination

remaining syringes need not be blanked. If any of representative syringes

show contamination, all 2 cc syringes must be blanked prior to use.

D) Syringe blanks are run with air or nitrogen.

E) If it is necessary for any syringe to be used again before cleaning, it is

blanked prior to its second use.

in. System Blanks

A) System blanks are ambient air drawn through the probe and complete

sampling apparatus (probe adaptor and 10 cc syringe) and analyzed by the

same procedure as a soil gas sample. The probe is above the ground.

B) One system blank is run at the begirming of each day and compared to

a concurrently sampled air analyses.

_

Tracer Reaearch Corporacion

C) A system blank is run before reusing any sampUng system component.

rv. Ambient Air Samples

A) Ambient air samples are coUected and analyzed a minimimi of two times

daily to monitor safety of the work environment and to estabUsh site

background concentrations, if any, for contaminants of interest.

B) All ambient air samples shall be documented (Figure 3).

V. Samples

A) All unknown samples wfll be analyzed at least twice.

B) More unknown samples will be run until reproducibility is within 25%,

computed as follows:

Difference = A - B (A + B)/2

Where; A is first measurement result

B is second measurement result

If the difference is greater than .25, a subsequent sample wiU be run until two

measurements are made that have a difference of .25 or less. Those two

measurements will be used in the final calculation for that sample.

C) The injection volume should be adjusted so that mass of analyte is as near

as possible to that which is contained in the standard, at least within a factor

of ten.

D) Whenever possible the attenuation for unknown samples is kept constant

through the day (so as to provide a visual check of integrations).

E) A water plug is used as a ga^ seal in uL syringes

F) A seal is established between syringes when subsampling

G) At very high concentrations air dilutions are acceptable once

concentration of contaminants in air have been estabUshed.

T r a c e r Researeh C o r p o r a c i o n

H) AU sample analysis are documented (Figure 3).

I) Separate data sheets are used if chromatographic conditions change

J) Everything is labeled in ug/L, mg/L, etc. PPM and PPB notations are to

be avoided.

A) Integrators parameters are initialized

1. Pt. evaluation

2. Attenuation

3. Peak markers

4. Auto zero

5. Baseline offset (min. 10% of fuU scale)

B) The baseUne is checked for drift, noise, etc.

C) System parameters are set.

1. Gas flows (Note: Nj, air, H^ tank pressure on Page 1 of

chromatograms).

2. Temperatures

a) Injector

b) Colunm

c) Detector

D) After last analysis of the day conditioned septa are rotated into injection

ports used during the day and replaced with fresh septa.

E) Column and injector temperatures are run up to bake out residual

contamination.

F) Syringes are cleaned each day

1. 2 and 10 cc syringes are cleaned with Alconox or equivalent

detergent and brush

10

T r a c e r Research C o r p o r a c i o n

2. uL syringes are cleaned daily with IPA or MeOH and

purged with Nj. Syringe Kleen is used to remove metal

deposits in the barrel.

3. Syringes are baked out overnight in the oven of the gas

chromatograph at a minimum temperature of 60''C.

v n . Sample SpUts

If desired, TRC's clients or any party, with the approval of TRC's cUent,

may use sample splits to verify TRC's soil gas or groundwater sampling

results.

A) Sample splits may be coUected in two valve, flow through-type all-glass

or intemally electroplated stainless steel containers for analysis within 10

days of colleaion.

1. Row through sample collection botties should be cleaned by

purging with nitrogen at 100°C for at least 30 minutes. Once clean, the

bottles should be stored filled with nitrogen at ambient pressure.

2. Sample bottles are fiUed by placing them in the sample

stream between the probe and the vacuum pump. Five sample

bottle volumes should be drawn through the container before

the final sample is collected. The sample should be at ambient

pressure.

B) Sample spUts can be provided in 10 cc glass syringes for immediate

analysis in the field by the party requesting the sample splits.

C) Splits of the aqueous standards or the methanol standards used by TRC

for instrument calibration may be analyzed by the party requesting sample

spUts.
