APPENDIX A
WORK SCOPE AND BUDGET
FAYETTEVILLE PILOT PLANT STUDY
INTRODUCTION
Background
This work plan outlines a proposed pilot plant program for
the Fayetteville, Arkansas, Wastewater Treatment Plant
(WWTP). The pilot plant is requested by the EPA on the basis
that the treatment process selected, while innovative,
includes enough risk to warrant a pilot plant to demonstrate
that the selected treatment process will work under
anticipated environmental conditions. The selected treatment
process includes biological nitrification and phosphorus
removal in a single activated sludge system using a variation
of the A/O process currently marketed by Air Products and
Chemicals, Inc. (APCI), Allentown, Pennsylvania.
Communications with the EPA and State of Arkansas Department
of Pollution Control and Ecology (ADPCE) officials indicate
the following list of potential objectives for the pilot
plant study:
1. To demonstrate the ability to obtain simultaneous
nitrification and biological phosphorus removal
during wintertime (cold temperature) operation.
2. To demonstrate the impact of nitrified mixed liquor
from the oxic to anoxic stage for denitrification
with special emphasis on optimizing the effects of
alkalinity.
3. To determine the impact of all side streams from
the solids processing area on process performance.
4. To determine chemical requirements to remove the
remaining phosphorus in the biological process ef-
fluent and the impacts of these chemical additions
on the operation of the tertiary filters and sludge
disposal, as well as the impact of sludge recycle
to the anaerobic basin.
Alternatives
Two alternatives were investigated to accomplish the four
potential objectives listed above:
1. Construction of a specially designed 15-gpm pilot
plant and operation for a 12 -month period. Both
A-1
-1.
cold -weather operation and warm -weather operation
would be simulated. A 4-ft2 pilot filter would
also be operated periodically to assess the perfor-
mance and impacts of filter operation.
2. Use of a one-gpm mobile pilot plant which can be
modified to be-ava7able from APCI for a period of
12 months to simulate both cold -weather and
warm -weather operating conditions. Jar testing
would be used to estimate the chemical requirements
for polishingthe effluent phosphorus concentration
and to evaluate the need for a continuous
pilot -scale filter and, if found to be required,
determine the effects of sludge recycle to the
anaerobic basin.
These two alternatives were reviewed internally and a deci-
sion was made to use the one-gpm mobile pilot plant. Reasons
for this selection include:
1. The 15-gpm specially designed pilot plant would
take longer to design and construct than the time
required to modify, move in, and set up the one-gpm
mobile unit. Since construction of the full-scale
plant will be occurring concurrently with this
pilot plant study, it is crucial that data be
collected during the cold weather in the 1984-1985
winter season. The longer time required for the
15-gpm unit could jeopardize the possibility of
obtaining cold -weather data during the winter of
1984-1985.
2. Examination of the design of the full-scale plant
indicates that recycle streams should have only a
negligible impact on the biological treatment
process. The principle recycles include gravity
thickener (primary sludge only) overflow, dissolved
air flotation thickener (waste activate sludge
only) subnatant, and effluent filter backwash. Of
these, gravity thickenerr overflow and dissolved air
flotation subnatant are not expected to contain any
more soluble BOD or phosphorus than primary efflu-
ent, and consequently, should not adversely affect
the biological system. Effluent filter backwash
will be returned ahead of primary treatment, where
some of the solids will be removed in the primary
clarifiers for discharge directly to the aerobic
digesters. The aerobic digesters will not be
decanted, and all digested sludge will be
land -applied.
3 Discussions with EPA Cincinnati indicated that the
EPA is primarily concerned about Objectives 1 and 2
A-2
•
•
listed above and that the one-gpm pilot plant
should be adequate to address these primary objec-
tives.
4. The 15-gpm alternative is estimated to cost about
$210,000 more than the cost of the one-gpm alterna-
tive.
OBJECTIVES
Based on the considerations listed above, the following
specific pilot plant study objectives are:
1. To operate a one-gpm pilot plant in a fashion which
simulates the design loading and operating con-
ditions for the Fayetteville variation of the A/O
process to determine the effluent ammonia, soluble
phosphorus, BOD, and CBOD concentrations which can
be achieved.
2. To demonstrate the feasibility of nitrified mixed
liquor recycle (for denitrification and alkalinity
recapture) and its impact on nitrification.
3. To conduct jar tests to determine the supplemental
chemical. requirements and to select the best chemi-
cal injection point to polish the biological
process effluent to meet effluent total phosphorus
standards (Table 1). Pilot -scale filtration may be
conducted based on future requirements of ADPC&E
following data review. Filtration studies are not
included in this work scope and budget.
4. If pilot -scale filtration studies are conducted,
recycle stream will be piloted and a determination
made on all aspects of the process.
APPROACH
Perspective
The new Fayetteville WWTP will have a design capacity of
17 mgd (11,800 gpm), while the pilot plant will have a design
capacity of about one gpm for a scale -down factor about
12,000:1. The number of stages per train will be identical.
Description
A listing of the unit sizes and design factors for the
full-scale facilities is shown in Table 2. Unit sizes and
design factors for the pilot plant are shown in Appendix C.
A simplified flow diagram showing the number of process
units, their arrangement, and recycle streams is shown in

Procedures
The pilot plant will be operated continuously during the
start-up, acclimation, and demonstration operation period.
Seed sludge will be added to the system from an operation AO
plant pilot to speed up the acclimation.
The feed to the pilot plant will be full-scale primary
clarifier effluent with existing recycle streams diverted
downstream of the take -off point. Recycle stream flows have
been accounted for in the pilot plant design and operation.
AP personnel will be involved in pilot plant start-up and
acclimation. During the actual operation period the pilot
plant will be attended 5 days a week by CH2M HILL and
McClelland Engineers staff. The planned staffing is for 40
hours a week by CH2M HILL's process engineers and 20 hours a
week by McClelland's technician. Weekend coverage will be
the minimum necessary to ensure continued operation of the
facilities.
Composite samples will be collected at selected sample points
with 24-hour composite samplers and will be collected on a
preselected flow proportional basis (to simulate actual
diurnal loadings). Additional information on the sampling,
testing, and influent flow rate variation is included in
Appendix B, Experimental Work Plan.
CH2M HILL will analyze data as it is collected and will make
process adjustment determinations. An independent consultant
will be retained by the City of Fayetteville to visit the
pilot plant and to provide an independent review of the
operating data and the pilot plant summary report. The
independent consultant will be retained during the start-up
period to advise on QA/QC procedures and to review planned
operations.

PROJECT PHASES
The project is divided into the following five phases;
planning, installation, acclimation, operation, and final
report. Each of these phases is discussed below.
Planning Phase
The initial project phase is a planning phase in which
project scope and activities are defined. Tasks in this work
phase include:
1. Development for project work plan
2. Development of project budget as scheduled
3. Provision for local pilot plant arrangements
including electrical and plumbing service
4. Development of subcontractor working agreements
5. Attendance of client, EPA, and ADPC&E meetings to
review and further define work scope and project
work plan
6. Development of independent consultant procurement
7. Development of lab procedures and protocols
Installation and Acclimation Phase
APIC will have primary responsibility to install the pilot
plant at the Fayetteville Wastewater Treatment Plant (WWTP)..
It is anticipated that this effort will take 14-21 days after
the pilot plant arrives onsite.
The pilot plant will receive primary clarifier effluent from
the existing facility. Vacuum filter filtrate will be
removed from the primary effluent so that this waste stream
will be compatible with the proposed full-scale primary
effluent stream. Modification to remove the filtrate line
and replacement of the filtrate pumps will be undertaken
during this phase of the work.
Specific tasks to be completed under this phase include:
1. Rerouting of vacuum filter filtrate line
2. Electrical hookup to pilot trailer
3. Field hookup of pilot components including inter-
connecting piping, unit leveling, electrical
4. Instrumentation calibration and checkout
5. Hydraulic testing of units
6. Sampler setup
A-7
•
Acclimation Phase
Following hydraulic checkout of the pilot plant, approximate-
ly one-month acclimation period will begin. The purpose of
this phase is to develop microorganisms suited for biological
removal of nitrogen and phosphorus and to begin to adjust
plant operation to goal conditions (solids retention time,
hydraulic retention time, aeration requirements, solids
recycle rates, etc.). Approximately 2-3 sludge ages are
required to acclimate the plant to the point where useable
data can be taken.
Activities planned for this work phase include:
1. Introduction of primary clarifier effluent to
system
2. Establish flows, recycled rates, solids wasting
rate
3. Establish sampling procedures
4 Initial data collection to assess progress of
acclimation
5. Training of operators
APCI will have a technician/operator onsite full-time during
the acclimation period. This period is critical to the
establishment of a biomass to accomplish phosphate and
nitrogen removal. APCI's familiarity with the process and
their equipment will greatly facilitate this process.
Active biological solids from an operating A/0 system will be
used to seed the pilot plant to expedite acclimation.
The Engineer's and Subcontractor's personnel will also be
involved in this phase. Their primary tasks will be to
become familiar with pilot plant equipment, process op-
erations, and control systems and to assist APCI staff in the
pilot plant operation.
Operation Phase
This phase of the project will begin following biological
acclimation, hopefully prior to January 1, 1985. The Engi-
neer will be fully responsible for this phase of the project,
assisted by the Subcontractor.
A total of six months of pilot plant operations are budgeted
and planned for. The anticipated schedule is as follows:
Winter Operation January 1 - May 1
A-8
•
Interim Operation
Summer Operation
Interim Operation
May 1 - July 1
July 1 - September 1
September 1 - December 30 (by
City forces)
The pilot plant will be operated by a process engineer and
technician during the operation phase. Each will work a five
day, 40 hour week with schedules developed to maximize
coverage of the pilot plant during the week, based on opera-
tional requirements.
During the interim operation period, May 1 through July 1,
the pilot plant will be operated only to maintain biological
activity with only the technician working 1/2 time, assisted
by WWTP staff as needed.
Sampling during this period is anticipated to be reduced 50%
from the operational period schedule.
A decision may made to adjust this schedule based on
reaching critical temperature, however, full pilot plant
operation beyond a total of six months will constitute a
change in work scope.
Monthly summary reports and data review will be prepared
during the course of the study. These will allow ongoing
process evaluation and assist in establishing process modi-
fications required for further study.
Report Phase
Two interim reports are planned. The first report will be in
mid-April after approximately 3 months of operation. The
second summary report will be presented in mid-October 1985
summarizing the second 3 months of operation. A final report
will be presented by January 30, 1986, summarizing the entire
pilot study
General Project Tasks
Over the course of the project study, several tasks will
occur. These include project management, senior process
review, client, EPA, and ADPC&E meeting, and data management.

SECTION 3. QUALITY ASSURANCE OBJECTIVES IN TERMS OF PRECISION
ACCURACY, COMPLETENESS, REPRESENTATIVENESS AND COMPARABILITY
Representativeness
The project Work Plan provides the sampling locations and frequencies.
All sampling sites have been selected on the basis of being those
necessary to obtain representative samples and to obtain necessary data
for process control and performance evaluation.
Comparability
All analytical procedures used are listed in Guidelines Establishing Test
Procedures for the Analysis of Pollutants; Proposed Regulations,
40 CFR, Part 136, Monday, December 3, 1979. All data is reported in
units required by STORET.
Precision
The precision of all analysis will be documented by the analysis of
duplicate samples. All field personnel must take at least one set of
duplicate samples with each group of samples taken. The frequency of
duplicate samples should be approximately one in ten samples.
The control limits for precision will be determined from past sets of
duplicate data. Data judged to be out of control will be discarded
before calculations are made. A series of control limits will be
determined for different concentration ranges for each parameter. The
control limits will be based on the arithmetic mean of the ranges, R, for
a concentration range. The range R for duplicate analyses is equal to
the difference between them. The upper control limit for each
concentration range will be calculated from the Shewhart Factor D4 for
duplicate analyses of 3.27 and the mean range.
UCL = 3.27 R
The upper control limit will be rounded to the appropriate units for each
concentration range.
When duplicate values are in different concentration ranges, the
appropriate concentration range will be determined from the arithmetic
mean of the values.
Section No. 3
Revision No.
Date
Page 2 of
The analysis will be in control when the range for the duplicates is less
than or equal to the upper control limit. When any difference between
duplicate analyses exceeds the upper control limit, the analyses must be
stopped until the problem is identified and resolved. After resolution,
the problem and its solution must be documented and all analyses since
the last -in control check must be repeated or invalidated.
The results of duplicate analyses must be recorded on the duplicate
sample worksheet and the values plotted on a control chart.
Accuracy
The accuracy of all analyses will be assured by the analysis of spiked
samples.
The spiked samples will be prepared by adding a known amount to an
aliquot of the duplicate sample taken by the field personnel. The
frequency of spiked sample analyses should be approximately one in every
ten samples.
Accuracy control limits and charts will be maintained for each parameter.
The control limits will be developed from actual data and will be based
upon the percent recovery of the spike.
The percent recovery P in natural water spikes is defined as:
P = 100 Final concentration - Initial concentration
Spike
The initial concentration is the average of the two duplicate values.
The average percent recovery for each parameter must be calculated from a
large number of spiked samples which have been judged to be in control
using:
- N
''
D.
P = i:1
N
Section No. 3
Revision No.
Date
Page 3 of
The standard deviation for percent recovery must be calculated using:
N N 2
S = P.2 - (E pi) IN
p i=1 1 i=1
N-1
The upper control limit is defined as:
UCL = P + 3 Sp
and the lower control limit is defined as:
LCL = P - 3S
The data used to prepare the control chart should be checked to be sure
that none of the values exceeds the new control limits. To check for
proper distribution, at least 50% of the data should fall within the
interval:
P ± Sp
The analysis will be considered out -of -control if either of the following
two conditions applies:
a. Any point beyond the control limits
b. Seven successive points on the same side of the value p of the
central line.
Precision, accuracy and completeness objectives are presented in Table
3.1.

CONTAINERS, PRESERVATION AND HOLDING TIMES
Table 4.1 lists the parameters and their recommended sampling containers,
their preservation times and procedures, and their maximum holding times.
The table is -based- on EPA 40 CFR part 136, Guidelines Establishing Test
Procedures for the Analysis of Pollutants, December 3, 1979. In general,
all samples will be iced immediately following collection and transported
to the laboratory within 1 hour.
SAMPLE SIZE
Adequate sample size is important to establish estimates of population
parameters to a prescribed accuracy. Determining sample size requires an
estimate of the allowable margin of error and the risk that the estimate
will be in error by that amount or greater.
Methods for determining the choice of sample size are based on the
relationship between the standard error of a statistic and the size of
the sample used to estimate it.
If a sample is selected at random and if it is less than 10% of the
population size, precision depends on the absolute size of the sample
rather than sampling ratio.

SECTION 5. CHAIN OF CUSTODY
The purpose of the chain of custody procedure is to demonstrate the
reliability of evidence by creating an accurate written record of the
possession of the sample from collection to possible introduction into
evidence. This procedure will also insure that the samples are
collected, transferred, stored, analyzed and destroyed only by
authorizing personnel.
CUSTODY
A sample is in custody if it is in anyone of the following states:
a) In actual physical possession
b) In view, after being in physical possession
c) In physical possession and locked up
d) In a secure area, restricted to authorized personnel
SAMPLE COLLECTION
A. All samples must be tagged (see Figure 5.1) or labeled at
the time of collection. The tag must contain as a minimum
the following items; the location; the date and time
taken; the name of the sample collector; analysis
required; and any preservative used.
A bound field notebook must be used. It must contain as a
minimum the same information as the sample tag and any
field measurements and other information necessary to
re -construct the sample collection process. All entries
should be signed and all field notebooks should be stored
in a safe place.
C. The sample collector is responsible for the care and
custody of the samples until they are relinquished. The
sample collector must provide the proper storage
conditions and insure the delivery of the samples within
the permitted holding times. The samples must be in his
physical possession or in his view or stored in a locked
place at all times.
Section No. 5

Date
Page 2 of
SAMPLE SHIPMENT AND TRANSFER OF CUSTODY
A. When samples are shipped by common carrier, a bill of
lading must be obtained. This bill of lading must be
retained as part of the permanent chain of custody.
B. Samples transferred to other personnel for delivery must
be accompanied by a chain of custody record. For
individual samples, this can consist of a relinquished by
signature and a received by signature on the sample tag.
For bulk transfer of a group of samples, a separate chain
of custody record sheet may be used. This sheet must
include the collector's signature, station number and
location, date, and time of collection. The transferrer
and transferree must sign, date, and time the record
sheet.
C. Samples must be delivered to authorized laboratory
personnel and the transfer of custody recorded by
signatures with the date and time of the person
relinquishing and the person receiving the samples.
D. The only persons authorized to receive samples in the
laboratory shall be the laboratory supervisor and an
alternate.
LABORATORY CUSTODY
A. All samples received in the laboratory shall be recorded
in a laboratory log book with the sample description, date
and time collected, name of person collecting sample, the
date and time received, and the person receiving the
sample.
B. The person receiving the sample is responsible for
distributing the samples to the laboratory personnel or
storing the samples under the appropriate conditions.
C. Laboratory
personnel are
responsible for the care and
custody of
a sample once
it is handed to them and
should
be prepared
to testify
that the sample was in
their
possession
and view or secured in the laboratory
at all
times.

SECTION 6. CALIBRATION PROCEDURES
All instruments and equipment will be calibrated according to the
manufacturer's recommended procedures and the guidelines in the Handbook
for Analytical Quality Control in Water and Wastewater Laboratories,
EPA -600/4 - 79 - 019. In addition, the following specific procedures
will be followed:
All analytical balances will be checked each week with a
set of weights. The reading of each weight should be
performed as per instructions given in Figure 6.1. The
reading of each weight should be recorded on the Quality
Control Sheet, Figure 6.2.
All pH meters will be calibrated immediately before use
with two buffer solutions. For best accuracy, the two
buffers should bracket the expected pH range of the
samples. All buffers used must be standardized against
standards of the National Bureau of Standards. The pH
meter must be recalibrated after every four hours of use.
All calibration readings are recorded on Quality Control
Form in Figure 6-.3.
C. All dissolved oxygen meters must be calibrated before each
use by using air calibration and water calibration using
water with a known oxygen concentration and water with
zero dissolved oxygen. The meter must be turned on and
warmed up for at least fifteen minutes before use. Water
for calibration must be prepared by filling two B.0.D.
bottles from well mixed water in B.O.D, dilution
cylinder. The D.O. of one bottle is determined using the
Winkler Azide method. The other bottle is used to
calibrate the meter. This calibration must agree with the
air calibration. The air calibration consists of placing
the electrode into a bottle with a small amount of water
in the bottom. The electrode must be in the air above the
water. Read the temperature after it reaches equilibrium
and determine the oxygen saturation at that temperature
corrected for the altitude.
0. All thermometers will be checked against a thermometer
certified by the National Bureau of Standards before being
used and at least once annually. The check should be
performed at least three temperature settings in the range
of 4°C to 30°C, preferably at 4°, 15°, and 30°C.
Section No. 6

E. All spectrophotometers must be checked for proper
wavelength and spectral transmittance quarterly as given
in Figure 6.4. Results are recorded on Quality Control
Form as seen in Figure 6.5.
FIGURE 6.1
Instrumentation Calibration and Performances
Instrument: Mettler
H 33 single pan analytical balance
Procedure: There
are 3 quality control procedures for evaluating and
maintaining
the performance of an analytical balance. Use
Class S
weights.
1) Correct
optical scale sensitivity as a function of load.
a.
Place a 100 mg. weight on the balance pan, set the weight
control knob to 0.1 g, release the balance and set the
zero point with the optical zero knob.
b.
With the balance released, slowly turn the weight control
knob back to zero. The optical scale should come to rest
exactly at 100 mg., arrest the balance, remove the top
housing cover and adjust the sensitivity weight.
c.
Replace the cover and repeat steps "a" and "b".
d.
Place a 100 mg. and 100g. weights on the balance pan, set
the weight control knobs to 100.1g, release the balance
and set the zero point with the optical zero knob.
e.
With the balance released, slowly turn the weight control
knobs to 100.0g. The optical scale should again come to
rest exactly at 100 mg. If the scale does not come to
100± 0.1 mg for a four -place balance, repeat steps "a" --
If the balance still does not meet this
specification, it should be serviced.
2) Reproducibility
of balance -- loaded and unloaded.
a.
Adjust the sensitivity of the balance as described in
Section 1.
b.
Release the beam of with the pan empty and zero the
balance. Arrest the beam, add a 100 g weight to the pan,
set the weight control knob to 100 g and release the pan.
Record the weight.
c.
Arrest the beam, remove the weight from the pan, re -set
the weight control knob to 0.0 g, release the beam and
record the new zero reading. Do no re -adjust the balance
zero. Record the values.
d.
Repeat steps "a" and "b" four or five times. Calculate
the average and standard deviation of the zero and 100 g
weight. The mean zero reading and standard deviation of
the 100 g weight should not be greater than 0.1 mg or the
balance needs servicing.
3) Internal
consistency of the balance weights.
a.
Place a 50 g weight on the pan, dial 50.0 g on the weight
control knobs, release the beam and record the reading.
Arrest the beam.
b.
Now dial 49.9 g on the weight control knobs, release the
beam, and again record the weight.
c.
Perform this exercise throughout the range 61' nterest,
say at 10 and 100 g. The difference in weights should
not be greater than ± 0.1 mg. If any difference is
larger, the internal weights have corroded.
Necessary frequency: Perform all the checks once a week until a pattern is
established. The zero check should be performed before each use.

Instrumentation Calibration and Performance
Instrument: Bausch & Lomb Spectronic 20 Spectrophotometer
Procedure:
Wavelength Calibration Check --Use 1/2" cuvettes
1. Prepare Cobalt Chloride Stock Solution: Place 22 g cobalt
chloride in a 1 -liter volumetric flask. Dissolve and make to
volume with 1% hydrochloric acid solution.
2. Set Wavelength Control to 500 nm.
3. Adjust Zero Control to zero, with sample compartment empty
--Cover closed.
4. Insert distilled water, set at 100% T.
5. Insert Cobalt Chloride Stock Solution and read %T, and Record.
6. Repeat steps #3-5 at 505, 510, 515, and 520 nm. Record all %T.
The instrument is in proper calibration when minimum
transmittance occurs between 505 and 515 nm.
Photometric Linearity Check --
1. Dilute 2.0 g of CoC1.6 H20 to 100 ml in 0.3 N HC1. Measure the
absorbance of this solution at 510 nm. Dilute an aliquot in
half and measure the absorbance again. Repeat this procedure
six more times. Record the absorbances. Plot the absorbance
vs. cobalt concentration using linear graph paper. Measure the
absorbance of cobalt solution using all of the sample cells.
Set aside all cells with absorbances that do not agree with 1%.
2. Prepare stock solutions of potassium dischromate in perchloric
acid and nickel sulfate in sulfuric acid at pH 2. Repeat the
experiments in part at 350 and 670 nm, respectively.
Stray light check --
1. Prepare a solution of 0.16 g potassium chromate per liter in
0.05 N potassium hydroxide.
2. Set the Wavelength to 374 nm and measure the transmittance of
the solution. Record the %T. The instrument's Specifications
call for stray light of 0.5%. If it is greater, check for
obvious light leaks. Stray light causes deviation from Beer's
Law. Stray light of 0.5 and 5% causes a deviation of 2 and
15%, respectively, at an absorbance of one.
Necessary frequency:
Quarterly. Or after any servicing of instrument (replacing bulbs,
etc.)

SECTION 9. INTERNAL QUALITY CONTROL CHECKS
LABORATORY
Standard Curves
A new standard curve will be established with each batch of new reagents,
using at least seven concentrations.
Quality Control of Analytical Runs
With each batch of analyses, the following tests will be performed:
o One blank on water and reagents
o One midpoint standard
o One spike to determine recovery
o One set of duplicate analyses
Results will be compared with previous in -control data and Quality
Control objectives as discussed in Section 3.
FIELD
Control checks will be performed to evaluate the reliability of sample
collection and handling. The following procedures will be used to
provide a check on some aspect of sampling.
1. Duplicate
samples -
samples
will be duplicated on a random
basis to
provide a
check on
precision.
2. Split samples - samples will be periodically split for
analysis at different laboratories to provide a check on
accuracy.
3. Spiked samples - known amounts of particular constituents
will be added to actual samples or blanks for additional
check on accuracy.
4. Sample preservation blanks - when
used as a
part of
the
sample program, preservatives will
be added
to blanks
in
normally used concentrations.
This will
assist
in
revealing any effects preservatives
may be
exerting
on
results. Any contribution by
preservatives will
be
subtracted from real sample values.

Steps for Field:
A comprehensive quality assurance program should include the following
steps for each parameter.
a. Take independent simultaneous samples A and B at the same
sampling point. Depending on the parameter, this might be
side -by -side grab samples or composite samples in
parallel.
b. Split sample A into equal volume samples Al and A2.
c. Split sample B into equal volumes and add spike T to one
of them; the latter sample becomes sample Bsf. As with
all spikes, the addition of T will be approximately double
the anticipated concentration level.
d. Add the same spike T to a distilled water sample furnished
by the laboratory and designate this sample as Df.
The QA samples
will
be
treated
in the same way as all routine samples;
that is, the
volume,
type of
container, preservation, labeling and
transportation
will
be
the same
for all.

Steps for Laboratory:
a. Analyze the blank and midpoint standard. If results are
unsatisfactory, resolve problems before continuing.
b. Analyze sample Df. If the percent recovery of T is
unsatisfactory (see QA objectives, Section 3) create a
similarly spiked, distilled water sample DI and analyze to
test for a systematic error in the laboratory or problem
with the spike.
c. Analyze samples B and Bsf. If B is below the detection
limit, or if B is greater than lOT or less than 0.11,
disregard the remainder of this step and proceed to Step
d. If the percent recovery of T from Bsf is
unsatisfactory, spike an aliquot of sample B the same way
in the laboratory so that a similar recovery can be
anticipated. Analyze this sample Bsl to test for
immediate sample interferences or a bad background result
B. If percent recovery from B is satisfactory, then the
interference must require a longer delay before analysis,
or other special conditions not present in the laboratory,
in order to have a noticeable effect upon recovery of the
spike.
d. Analyze Al and A2. If absolute difference between these
results exceeds the critical value, then precision is out
of control.
e. Calculate the absolute difference between Al and B. If it
is unsatisfactory the field sampling procedure did not
provide a representative sample.

a. All analytical balances in use will be checked with a set
of Class S weights each week. The reading of each weight
will be recorded on the balance quality assurance check
sheet which will be kept on each balance.
b. The temperature of all B.O.D. incubators should be checked
daily and recorded on the quality assurance check sheet,
Figure 9.1. The temperature will be checked by measuring
the temperature of the container of water kept in the
incubator. The temperature should be measured to the
nearest 0.1°C. The temperature must be 20° ± 1.0°C at all
times. Corrective action, adjustment or repair must be
taken if this temperature range is not met.
c. The temperature of all residue drying ovens must be
checked daily and recorded on the quality assurance check
sheet. The temperature of the non -filterable residue oven
must be 103°-105°C, and the temperature of the filterable
residue oven must be 180°C ± 2°C. Corrective action,
adjustment, or repair must be taken if these temperatures
are not correct.
d. The results of each pH calibration must be recorded on the
quality assurance check sheet. If the electrode response
to two buffers shows differences greater than 0.1 pH unit,
corrective action must be taken. If recalibration,
cleaning the electrodes, or changing the buffers does not
solve the problem, the electrodes may have to be replaced.

month. The laboratory bench sheets will be reviewed by the laboratory
supervisor in a one month block. The quality control charts will be
checked along with the bench sheets. Any changes in the precision and
accuracy of the data will be investigated.
The quality control charts will also be examined every six months and if
changes in the precision or accuracy have occurred, new control limits
must be calculated. These changes will most often occur with equipment
changes and increasing analyst proficiency. New personnel will be given
sufficient training to meet the quality assurance standards before
allowed to perform the analyses on samples.
Statistical procedures applicable to assessing data precision and
accuracy include:
Central tendency and dispersion
o Arithmetic mean
o Range
o Standard deviation
o Relative standard deviation
o Pooled standard deviation
o Geometric mean
Measures of variability
o Accuracy
o Bias
o Precisions; within laboratory and between
laboratories
o Significance test
o u -test
o t -test
o F -test
o Chi-square test

SECTION 13. CORRECTIVE ACTION
Whenever the internal control checks or performance audit indicates an
out -of -control situation, corrective action must be taken.
An analysis will be considered out -of -control any time the control limits
are exceeded. The analyst is responsible for directing out -of -control
situations and initiating the corrective action.
When an out -of -control situation occurs, the analysis must be stopped
until the problem has been identified and resolved. The corrective
action must be approved by the laboratory supervisor and documented. All
analysis since the last in -control point must be repeated or the data
invalidated.

SECTION 14. QUALITY ASSURANCE REPORTS
A monthly quality assurance report will be prepared and submitted to the
ESCOMLAB Project Quality Control Officer. A copy will be sent to CH2M
Hill, the Independent Consultant, and the appropriate QA coordinator for
Arkansas Department of Pollution Control and Ecology. This report will
include all parameters for quality control such as percent samples
duplicated, percent samples piked, samples voided, parameters voided,
scheduled samples not collected, exceptions to holding times and
narrative of any action taken. Also, it will include the results of any
performance audits, system audits and significant QA problems and
recommended solutions. The ESCOMLAB Laboratory Supervisor will be
responsible for preparing the periodic reports.
With the completion of the project, a final QA report will be prepared
which summarizes data quality information contained in the periodic
reports.
