SOIL BORING LOG GUIDELINE

SOIL BORING LOG POLICY

This soil boring guideline will be used for all CH2M HILLprojects in which soil boring techniques are used duringgeotechnical field exploration. The purpose of the guide-line is to assist CH2M HILL staff in accurately recordingand presenting all field data that are necessary to suffi-ciently describe, label, and package recovered soil samplesin a consistent manner. The guideline establishes theminimum kinds of information that must be recorded in thefield to adequately characterize recovered soil samples.

Because each of our projects is unique and because job re-quirements can vary widely, the minimum standards presentedin this guideline may need to be supplemented with addi-tional technical descriptions or field test results. How-ever, all soil boring field logs, regardless of specialproject circumstances, must include information addressed inthis guideline to achieve minimum acceptable standards re-quired by CH2M HILL,

All CH2M HILL staff members are encouraged to present theirsuggestions for clarification or improvements to this guide-line. Please submit all suggestions or comments in writingto the Geotechnical Discipline Group Director.

RECORDING SOIL BORING FIELD DATA

CH2M HILL Standard Form D1586, the Soil Boring Log form,will be used on all CH2M HILL projects for field logging(see Figure 1). Adherence to a standard format for record-ing data will help streamline our project efforts and ensurea consistent presentation of factual subsurface data. Allheading information must be completely filled out on eachlog sheet used, and all technical items in each column mustbe addressed in the field.

The boring log should be completed in the field according tothe attached instructions. Forms should be filled out neatlyand completely. Laboratory testing, if required, should beinitiated immediately after completion of the field work.Field classifications of samples should be checked againstthe laboratory test results, and corrections should be noted,initialed, and dated on the field log.

INSTRUCTIONS FOR COMPLETING SOIL BORING LOG, FORM D1586

Form D1586 is a standard CH2M HILL form that is available inweatherproof paper from all regional form distributors.

Following are instructions for completing the log forms inthe field. See Figure 2 for an example of a field log com-pleted according to the instructions.

Field personnel should review logs on completion for accu-racy, clarity, and thoroughness of detail. Samples shouldalso be checked to see that information is correctly re-corded on both jar lids and labels and on the log sheets.

If any changes to the soil classification are made on thelog forms after completion of the field work, they should bedone in red, then initialed, and dated.

Heading Information

Project Number. Use standard region code, contract I.D.(5-digit), and point number designated for field explorationor geotechnical services.

Boring Number. Enter the boring number. A numbering systemshould be chosen that does not conflict with informationrecorded for previous exploratory work done at the site.Number the sheets consecutively for each boring. If rockcore log sheets are also used, continue the consecutive num-bering.

Project. Fill in the name of the project or client.

Location. If stationing, coordinates, mileposts, or similarproject layout information is available, indicate the posi-tion of the boring with respect to that system, using modi-fiers such as "approximate1* or "estimated" as appropriate.If this information is not available, identify the clientfacility (e.g., Richland STP, center of Clarifier No. 2site) or the town and state.

Elevation. Enter the elevation. If it is estimated from atopographic map, or if it is roughly determined using a handlevel, use the modifier "approximate." If the elevationsare to be surveyed later, or if the elevation is unknown,enter this information.

Drilling Contractor, Enter the name of the drilling companyand the city and state where the company is based.

Drilling Method and Equipment. Identify the bit size andtype, drilling fluid(e.g./ mud, Revert), and method ofdrilling (e.g., rotary, hollow-stem auger, air track).Information on the drilling equipment (e.g., CME 55, MobileB61) should also be entered here.

Water Level and Date. Enter the depth at which groundwateris first encountered. If frequent water measurements aretaken, the information should be recorded in the Comments

PD253.016.3

column. If water is not encountered during drilling, orcould not be detected because 01 the drilling method, thisinformation should be noted. Generally, water levels shouldbe measured each morning before resuming drilling and at thecompletion of each boring. Record date and time of day (fortides, river stage, etc.) of each water level measurement.

pate of Start and Finish. Enter the dates the boring wasbegun and completed.Time of day may be added if severalborings are performed on the same day.

Logger. Enter the first initial and full last name.

Technical Data

Depth Below Surface. Use a depth scale that is appropriatefor the sample spacing and for the complexity of subsurfaceconditions.

Sample Interval. Draw horizontal lines at the top and bot-tom depth of each sample interval. These lines shouldextend to the soil description column. For a very shortsample interval, the bottom line can be lowered after theinterval column to provide room for writing the information(see Figure 2). Enter the depth at the top and bottom ofthe sample interval.

Sample Type and Number. Enter the sample type and number.For instance/ SI = split spoon, first sample. Number sam-ples consecutively regardless of type. Enter a samplenumber even if no material was recovered in the sampler.

Sample Recovery. Enter the length to the nearest tenth of afoot of soil sample recovered from the sampler.

Standard Penetration Test Results. In this column enter thenumber of blows required for each 6 inches of sampler pene-tration and the "N" value, which is the sum of the blows inthe last two 6-inch penetration intervals. A typical stan-dard penetration test involving successive blow counts of 2,3, and 4 would be recorded as 2-3-4 and (7). The standardpenetration test will be terminated if the sampler encoun-ters refusal. Refusal is a penetration of more than6 inches but less than 12 inches with a blow count of 100,or a penetration of less than 6 inches with a blow count of50. A partial penetration of 50 blows for 4 inches is re-corded as 50/4".

Soil Description. The soil classification should follow theformat described in the section below entitled "Field Class-ification of Soil."

Symbolic Log. This column is usually omitted during field-work.

PD253.016.5

Comments. Include all pertinent observations {e.g./ changesin drilling fluid color, rod drops, drilling chatter, rodbounce as in driving on a cobble, damaged Shelby tubes, andequipment malfunctions). Also note if casing was used, thesizes and depths installed, and if drilling fluid was addedor changed. You should instruct the driller to alert you toany significant changes in drilling (e.g., changes in mate-rial, occurrence of boulders, and loss of drilling fluid).Such information should be attributed to the driller andrecorded in this column.

Specific information might include:

• The date and the time drilling began and endedeach day

• The depth and size of casing and the method ofinstallation

• Depth of rod chatter

• Depth and percentage of drilling fluid loss

• Depth of hole caving or heaving

• Depth of change in material

• Drilling interval through a boulder

• The results of pocket penetrometer or torvane testreported as:respectively

'PP TSF" or "TV TSF,"

The depth of piezometers and the results of in situ testsshould be noted in the Comments column.

FIELD CLASSIFICATION OF SOIL

This section presents the format for the field classifica-tion of soil. All descriptions of soil will be done inaccordance with the Unified Soil Classification System(USCS), ASTM D 2487-85 (Figures 3 and 4). The approach andformat for classifying soils should conform, in general, toASTM D 2488-84, Visual-Manual Procedure for Description andIdentification of Soils.

The Unified Soil Classification System is based on numericalvalues of certain soil properties, which are measured bylaboratory tests. It is possible, however, to estimatethese values in the field with reasonable accuracy usingvisual-manual procedures. Also, some elements or a completesoil description, such as the presence of cobbles or boul-ders, changes in strata, and the relative proportions of

soil types in a bedded deposit, can be obtained only in thefield. Corrections and additions to the field classifica-tion can be provided, when necessary, by laboratory testingof the soil samples.

Soil descriptions should be precise and comprehensive with-out being verbose. The correct overall impression of thesoil should not be distorted by excessive emphasis on in-signiticant details. In general, similarities between con-secutive samples should be stressed rather than differences.

Soil descriptions shall be recorded in the Soil Descriptioncolumn for every soil sample collected. The format and orderfor soil descriptions should be:

1. Soil name (synonymous with ASTM D 2487-85 GroupName) with appropriate modifiers

2. Color

3. Moisture content

4. Relative density or consistency

5. Soil structure or mineralogy

6. Group symbol

This order follows, in general, the format described in ASTMD 2488-84. Examples of soil descriptions are provided inTable 1.

Soil Name

The basic name of a soil shall be identical to the ASTMD 2487-85 Group Name based on visual estimates of gradationand plasticity. The soil name should be capitalized. Theonly acceptable soil names are those listed in Figures 3 and4, which are trom ASTM D 2487-85.

Examples of acceptable soil names are illustrated by thefollowing:

A soil sample is visually estimated to contain 15percent gravel, 5b percent sand, 30 percent fines(passing No. 200 sieve). The tines are estimated aseither low or highly plastic silt. This sample isSILTY SAND WITH GRAVEL, with a Group Symbol of (SM).

Another soil sample has the following visual estimate:10 percent gravel, 30 percent sand, and 60 percentfines (passing the No. 200 sieve). The fines areestimated as low plastic silt. This sample is SANDYSILT. The gravel portion is not included in the soil

PD253.016.9

Table 1EXAMPLE SOIL DESCRIPTIONS

POORLY GRADED SAND, fine, well-rounded, light brown, moist, loose (SP)

FAT CLAY, dark gray, moist, stiff (CH)

WELL-GRADED SAND WITH GRAVEL, subangular gravel to 0.6 inches max,reddish brown, moist, dense, (SW)

POORLY GRADED SAND WITH SILT, white, wet, medium dense (SP-SM)

PDP253.021.1 10

name because the gravel portion was estimated as lessthan 15 percent. The Group Symbol is (ML).

The gradation of coarse-grained soil (more than 50 percentretained on No. 200 sieve) is included in the specific soilname in accordance with ASTM D 2487-85. There is no need tofurther document the gradation. However, the maximum sizeand angularity or roundedness of gravel and sand-sizedparticles should be recorded. For fine-grained soil (50percent or more passing the No. 200 sieve), the name ismodified by the appropriate plasticity/elasticity term inaccordance with ASTM D 2487-85.

Interlayered soil should each be described starting with thepredominant type. An introductory name should be used suchas "Interlayered Sand and Silt." Also, the relativeproportion of each soil type should be indicated (seeTable 1 for example).

Where helpful, the evaluation of plasticity/elasticity canbe justified by describing results from any of the visual-manual procedures for identitying fine-grained soils, suchas reaction to shaking, toughness of a soil thread, or drystrength as described in ASTM D 2488*84.

Color

The basic color of a soil, such as brown, gray, or red,shall be given. The color term can be modified, if neces-sary, by adjectives such as light, dark, or mottled. Thecolor description should be kept simple and should notemphasize unimportant color aspects or shades.

Moisture Content

The degree of moisture present in a soil sample should bedefined as dry, moist, or wet. Moisture content can beestimated as follows:

Dry Requires addition of considerable moisture toobtain optimum moisture content

Moist Near optimum moisture content

Wet Requires drying to obtain optimum moisturecontent

Relative Density or Consistency

Relative density of a coarse-grained (cohesionless) soil isbased on N-values (ASTM D 1586-84). If the presence oflarge gravel or disturbance of the sample makes determina-tion of the in situ relative density or consistency

PD253.016.10 11

difficult, then this item should be left out of the descrip-tion and explained in the Comments column of the soil boringlog.

Consistency of fine-grained (cohesive) soil is properlybased on results of pocket penetrometer or torvane results.In the absence of this information, consistency can be esti-mated from N-values. Relationships for determining relativedensity or consistency of soil samples are given in Tables 2and 3.

Soil Structure or Mineralogy

Discontinuities and inclusions are important and should bedescribed. Such features include joints or fissures, slick-ensides, bedding or laminations, veins, root holes, and wooddebris.

Significant mineralogical information should be noted. Ce-mentation, abundant mica, or unusual mineralogy should bedescribed, as well as other information such as organicdebris or odor.

Residual soils have characteristics of both rock and soiland can be difficult to classify. Relict rock structureshould be described and the parent rock identified if pos-sible.

Group Symbol

Each soil description is concluded with the appropriategroup symbol trom ASTM D 2487-85 (see Figures 3 and 4). Thegroup symbol should be placed in parentheses at the end ofthe description to indicate that the classification has beenestimated.

In accordance with ASTM D 2488-84, dual symbols (e.g., GP-GMor SW-SC) can be used to indicate that a soil is estimatedto have between 5 and 12 percent fines. Borderline symbols(e.g., GM/SM or SW/SP) can be used to indicate that a soilsample has been identified as having properties that do notdistinctly place the soil into a specific group. Generally,the group name assigned to a soil with a borderline symbolshould be the group name for the first symbol. The use of aborderline symbol should not be used indiscriminately. Everyeffort should be made to first place the soil into a singlegroup.

STANDARD PENETRATION TEST PROCEDURES

Standard Penetration Tests (SPT) are conducted to obtain ameasure of the resistance of the soil to penetration of thesampler and to recover a disturbed soil sample. StandardPenetration Tests should be conducted in accordance withASTM D 1586-84, Penetration Test and Split Barrel Samplingof Soils.

Equipment and Calibration

Before starting the testing, the necessary equipment shouldbe inspected for compliance with the requirements of ASTMD 1586-84. The split-barrel sampler should measure 2 inchesO.D., with 1-3/8 inches I.D., and should have a split tubeat least 18 inches long. The dimensions should conform withthose indicated on Figure 1 of ASTM D 1586-84. The minimumsize sampler rod allowed is "A" rod (1-5/8 inches O.D.). Astiffer rod, such as "N" rod (2-5/8 inches O.D.), isrequired for depths greater than 50 feet. The drive weightassembly should consist of a 140-pound hammer weight, adrive head, and a hammer guide that permits a tree fall of30 inches.

Procedures

Standard Penetration Tests should be conducted at everychange of strata or, within a continuous stratum, at inter-vals not exceeding 5 feet. Betore driving the split-barrelsampler, all loose and foreign material should be removedfrom the bottom of the borehole. It may be helpful to mea-sure the rod "stickup" to ensure that the sampler is beingdriven from the bottom of the borehole. The Standard Pene-tration Test should be performed by driving a standardsplit-barrel sampler 18 inches into undisturbed soil at thebottom of the borehole by a 140-pound guided hammer or ram,falling freely from a height of 30 inches.

The number of blows required to drive the sampler for three6-inch intervals, for a total of 18 inches, should be ob-served and recorded on the soil boring log. The sum of thenumber of blows required to drive the sampler the second andthird 6-inch intervals is considered the Standard Penetra-tion Resistance (N) or the "blow-count." It the sampler isdriven less than 18 inches, but more than 1 foot, thepenetration resistance (N) is that for the last 1 foot ofpenetration. If less than 1 foot is penetrated, the logshall state the number of blows and the traction of 1 footpenetrated. If possible, the field logger should observethe sampler being driven and count the blows for each sampleattempt.

General Considerations

The following comments and suggestions should be consideredwhen performing Standard Penetration Testing:

1. The borehole should be cleaned out before every sampleattempt. Because a minor amount ot caving can beexpected, the borehole can be considered to be ade-quately cleaned if no more than 4 inches of loose orforeign material has collected at the bottom of theborehole. A greater amount of caving is sufficientcause to require the hole to be cleaned again.

PD253.016.14 14

2. The ball check valve in the split-barrel sampler shouldbe cleaned and working properly for each sample. Bent,chipped, or damaged shoes should be replaced. The split'barrel halves should not be warped. In case of zerosample recovery (i.e., if the sample is lost duringfirst attempt), a spring catcher should be used duringsubsequent attempts to facilitate recovery.

3. During SPT sampling, it is important that all rodconnections be tight and that the hammer guide be con-nected securely to the drill rods. If the hammer guideconnection becomes loose, much of the hammer energy maybe lost because of deflection of the hammer coupling.The lifting rope should not rub against the mast. Eachhammer fall should be 30 inches.

4. During SPT sampling, it is important that the drillrods be positioned at the center of the drill hole.This is necessary to preclude the development of fric-tion between drill rods and the walls of the boreholeor casing.

5. If the hammer weight is raised by means ot a cathead,generally two wraps on the cathead should be used. Theoptimum number of wraps will vary with the condition ofthe rope and cathead and the weather. Most impor-tantly, the driller should exercise care to preventfriction of the rope on the cathead during the fall ofthe hammer.

6. Occasionally, nonstandard procedures or equipment areused for obtaining samples (such as 3-inch O.D. split-barrel samplers, or 300-pound hammers). Any nonstan-dard practice should be described on the boring logform. Also, the blow counts should be clearly markedas not conforming to SPT values.

SAMPLE LABELING AND PACKAGING

The samples recovered from the borehole are an importantpart of the boring record and must be properly packagedand labeled. Samples that are improperly or inadequatelylabeled are useless. The following description outlines theminimum requirements for packaging and labeling of samples.

Disturbed samples should be placed in jars that are markedboth on the jar lid and on a label on the side of the jar.Standard CH2M HILL jar labels are available (Form No. 131,Soil Sample Labels) for this purpose. The following infor-mation should be clearly marked on the jars: job number,boring number, sample number/ sample depth, blow counts,sample recovery, and date. Use an indelible marker or ametal scriber on the jar lid. If moisture content tests areanticipated, jar samples should be tightly sealed, then sent

PD253.016.15 15

to the laboratory and the testing initiated as soon aspossible (within one week). See Figure 5 for labelingdetails.

Boxes containing the jars should be labeled on top and onone end with the following information: job name, jobnumber, boring number, sample numbers and sample depths,date, and name. It is helpful to start a new box for eachnew boring if the boxes are at least one-half full.

Shelby tubes should be cleaned of mud and moisture. Whendry, use an indelible marker to label them with the follow-ing information: an arrow indicating which way is up, }obnumber, boring number, sample number and depth, amount ofrecovery, and date. The top and bottom of the sample can becircumscribed on the outside of the tube with a marker.

Waxing of Shelby tubes is essential if sample testing willnot occur within a few days. In all cases, lids should beplaced on the ends and taped with airtight tape. Makecertain that the holes in the top of the tube are sealed.The open portion of the tube, above the sample, should bepacked to prevent shifting of the soil. Dampened newspaperis generally adequate for this purpose, but it should beseparated from the soil sample by a wax seal or an invertedcap. See Figure 5 for labeling and packing details.

measurement procedures

general measurement techniquetemperature: All samples and buffers should be at the same temperature, assmall variations In temperature can cause errors In measurement. The slope ofthe pH electrode, the potential of the reference electrode, and the pH of the buf-fer are temperature-dependent.cleaning electrodes: Electrode should be rinsed and shaken between measure-ments to remove drops and to prevent solution carryover.stirring: Stir measured solutions moderately to obtain good contact betweenthe glass bulb and the solution. Insert electrode to a depth ol about 3 cm.

pH measurementssingle-butter standardization(where maximum precision is not required)NOTE: For maximum accuracy It is recommended that a Iwo-bulfer calibrationbe performed once at the beginning of each day (see page 7), This procedure en-sures the correct setting of the slope control. Subsequent measurements duringihe day may be made using a single point calibration.

1. Place the electrode In a butler solution whose pH Is near Ihe expected pH ofthe sample. Insert electrode to a depth ol about 3 cm and stir moderately.

2. Set Ihe temperature Indicator control to the temperature of the butter.3. Set the function control to ON and allow the bulfer reading to stabilize. Ad-

just the CALIB so that Ihe display indicates Ihe pH of the buffer at the solution temperature. See Table 1.

4. Remove the electrode from the buller solution and rinse by stirringmoderately in distilled water. Shake off excess drops ol waler.

5. Place electrode in the sample lo a depth ol about 3 cm and stir moderately.Set the function control lo ON and allow Ihe reading lo stabilize Record Ihesteady pH leading.

two-buffer standardization(where maximum precision is required)

1. Select two buffers to bracket Ihe expected pHol the sample, with one bulfer having a pH ol 7.

2. Place Ihe electrode in the pH 7 bulfer lo a depth of about 3cm and stirmoderately. Set Ihe temperature Indicator control to the temperature ol thebutler. Set Ihe function control lo ON and allow the reading lo stabilizeTurn CALIB until ihe display indicates Ihe pH ol Ihe buller at Ihe solutiontemperature. See table 1.

3. Remove electrode from Ihe lirsl buller and rinse by stirring moderately indistilled water. Shake off excess drops of waler.

4. Place the electrode In the second buller lo a depth ol about 3 cm and slirmoderately. Set the function control lo ON and adjust the slope control un-til Ihe pH at Ihe solution temperature is displayed. See Table 1.

5. Remove Ihe electrode and rinse by stirring moderately in distilled waterShake off excess drops ol waler.

6. Place Ihe electrode in Ihe sample lo a depth of about 3 cm and slirmoderately. Set Ihe function control to ON and allow the reading tostabilize. Record Ihe steady pH reading.

SPECIAL SAMPLE PREPARATION FOR SOIL SAMPLES

(CH2M HILL Method VWF-1)

1. SCOPE AND APPLICATION

1.1 This sample preparation method is presented as a

means to prepare composite soil samples in associa-

tion with the Remedial Investigation/Feasibility

Study (RI/FS) phase of the Verona Well Field

project.

1.2 The intent of the special sample preparation method

described herein is to maintain sample integrity

by minimizing loss of volatile constituents from

the soil.

2. SUMMARY OF METHOD VWF-1

2.1 The method has been designed to accommodate col-

lection of a representative aliquot of soil from

approximately 270 brass liners while minimizing

loss of volatile constituents. Soil samples will

be received by the laboratory in a brass liner and

preserved on ice. The samples will be prepared

and analyzed within 14 days of the time of collec-

tion.

2.2 Composite samples are prepared by extracting an

aliquot of soil from the entire length of each

brass liner by using a coring utensil similar to a

conventional laboratory cork boring tool. The

soil will be allowed to thaw and the boring device

cored through the center of the soil plug. Ali-

quots of soil obtained from each sample liner are

immediately placed into methanol to effect a sol-

vent extraction of the soil. Soil cores from

three designated brass liners are composited to

form each analytical sample destined for analysis.

A portion of the methanol extract is recovered for

analysis in accordance with the U.S. EPA Contract

Laboratory Program (CLP) Statement of Work for

GC/MS analysis of VOCs by the medium level method

for soil samples.

SAFETY

3.1 Samples are contaminated with constituents that

are either identified as, or suspected of being,

carcinogens. All samples are considered to be

hazardous. As such, they are to handled with the

utmost care and following established laboratory

technique in order to avoid harmful exposure.

3.2 Sample liners will have been stored on ice prior

to arrival at the lab. They should be handled

with hands covered first by surgical gloves and

then insulated gloves,

3.3 Samples shall be prepared in a fume hood. This

includes all subsampling and compositing activ-

ities.

4. APPARATUS AND MATERIALS

4.1 Sample coring utensil, similar to a laboratory

cork boring tool suitable for collecting a repre-

sentative aliquot of sample from the entire length

of a brass liner.

4.2 Bottles, 4-ounce (120 mis), wide-mouth amber glass

jars with teflon-lined caps, for use in extraction

of soil.

4.3 Analytical top loading balance, used to determine

the weight of sample aliquots to the nearest

0.01 grams.

4.4 Labware, pipettes, and glassware, as needed for

preparation of samples.

5. CHEMICALS AND REAGENTS

5.1 Methanol, spectrographic grade suitable for use in

accordance with CLP SOW for GC/MS analysis of VOCs.

5.2 Refrigeration, as required to keep samples at 4°C

prior to and after sample preparation.

6. SAMPLE PREPARATION STEPS

For Composites of Soil Samples Collected During the

Soil Boring Phase of RI/FS sampling.

6.1 Allow the sealed brass liner containing the sample

to thaw out such that the soil can be sampled in

the manner described in this section. It is rec-

ommended that a set of practice samples be pre-

pared from soil similar to that of the samples.

These can be used for perfecting the coring tech-

nique .

6.2 Remove the teflon-lined cap from one end of brass

liner to expose the end of the soil sample.

6.3 Using a preweighed coring utensil, immediately

collect an appropriate aliquot of sample by pushing

the utensil downward into the length of the liner.

Withdraw the coring utensil and reweigh to verify

that an adequate aliquot (i.e., 15 grams) of sample

has been obtained. This aliquot and aliquots from

other samples that make up a particular composite

should be of approximately equal weight (plus or

minus 10 percent). Record the weight of the sample

aliquot and all other soil aliquots used in the

makeup of the composite sample.

6.4 Immediately extrude the contents of the coring

utensil into a 4-ounce brown glass bottle that

contains an appropriate volume (i.e., 45 mis) of

methanol to accommodate the aliquots of each sample

to be composited. Soil cores from three designated

brass liners will be composited in the same bottle

to form each analytical sample. It is important

that approximately a 1:1 ratio of methanol volume

(mis) and total composite sample weight (gms) be

maintained to preserve the detection limit of the

analytical method. Record the volume of methanol

used in the extraction.

6.5 After addition of the sample aliquots to the meth-

anol, cap the bottle and extract the sample by

vigorous shaking for 2 minutes.

6.6 Recover a portion of the methanol extract for

analysis by U.S. EPA CLP SOW for GC/MS analysis of

VOCs by the medium level method for soil samples.

6.7 In accordance with the analytical method, the

amount of sample extract added to the sparging

cell of the purge and trap concentrator shall not

exceed 2.0 percent of the volume of water also

added to the sparging cell. However, it is impor-

tant for detection limit determinations that this

2.0-percent methanol/water relationship be ap-

proached in the analysis.

6.8 Should any delay occur between the extraction of

composite samples and the analysis, the sample

extracts shall be sealed in extract vials and

refrigerated.

6.9 All sample liners shall be recapped and placed in

the refrigerator after the sample aliquots have

been taken.

7.0 QUALITY ASSURANCE

7.1 Quality assurance associated with this special

sample preparation method is described in the

Quality Assurance Project Plan (QAPP) for this

project. QA/QC steps prescribed in the QAPP will

assess the precision and accuracy of the sample

preparation techniques.
