l. Introduction l The 1998 Big Rock' Point Annual Radiological Environmental Operating Report I provides a summary and data interpretation of the Big Rock Point Radiological Environmental Monitoring Program as conducted during the 1998 reporting period. Reporting requirements are detailed in Technical Specifications 6.7.2, and ODCM Section Ill item 2.0.'

There are no remaining 1998 laboratory sample analyses pending completion for inclusion into this report. Detailed sample station identification and location information can be found in Attachment 2 of Health Physics Procedure HP 10.9 (Enclosure D). The results of all environmental samples collected were evaluated as follows: ,

A.- Air iodine and particulate, TLDs (monthly and quarterly), were statistically evaluated at the 95% confidence level by the methodology detailed in Health Physics Procedure HP 10.2. The data was compared against two criteria: the first criterion is the statistical difference which indicates whether -

the sample results from near sites are greater than those from control sites, and whether or not the difference is significant. The second criterion is the evaluation level (twice the statistical difference) which is the minimum population mean difference for which the sample mean difference will exceed the statistical difference with 95% confidence. If the evaluation level is exceeded, then correlation of the results with effluent releases is done.

B. Well water, lake water intake / discharge, sediment, fish and other aquatic biota samples were evaluated using data means comparisons against an appropriate control location (if available) and BRP Technical Specification limits.

II.- ' Discussion and Interoretation of Results A. Air Samoles Comparison of the airborne particulate sample data between near-site and control locations resulted in no data exceeding the statistical difference level and no data exceeding the statistical evaluation level. In many instances, control location sample values were greater. There was no lodine-131 activity reported above minimum detectable levels.

A total of 312 air samples were collected during 1998. For the gross beta analysis four sample results were not included in the statistical evaluation.

Two due to the filter being bypassed, and two with low sample volumes due

l l

2 to wintery conditions - wet filters. Refer to Enclosure A for all sample collection anomaly evaluations. Technical Specification sensitivities were met on all samples other than those already noted. l Comparison of the airborne particulate sample data between near-site and control locations did not exceed the statistical difference. The means of gross beta results for indicator and control locations were 0.016 pCl/m' and 8

0.017 pCi/m respectively. No sample analysis identified 1-131 activity i above minimum detectable levels.

The air iodine / particulate samples are collected on a weekly basis from six air sampling locations. A seventh station, located on the Big Rock Point Plant site, is used for plant trending purposes only and is not part of the Radiological Environmental Monitoring Program. Air is metered through the sampling units at a continuous one cubic foot per minute flow rate through a Gelman 47mm air filter (air particulate) and a Scott air iodine cartridge. Both filters are in-line with each other and housed within the swne filter holder.

The 1998 air sample results are consistent with actual effluent releases and 1 site-specific meteorology.

B. TLDs - Gamma Dose There were a total of 144 monthly,48 quarterly and 12 annual TLDs collected for the Radiological Environmental Monitoring Program during 1998. Sixty additional on-site TLDs are used for individual reference and are not evaluated as part of the Radiological Environmental Monitoring i Program.

The Big Rock Point gamma assessment program consists of eighteen TLD locations: five on-site TLDs (locations 1-ST,14-G,15-H,17-K,18-L), six inner ring TLDs at the site boundary (locations 9-A,10-B,11-C,12-D,13-F, 16-J), three outer ring TLDs, 3 to 4.5 miles out, (locations 2-NM,3-CH,4-SL), three control TLDs,10.5 to 50 miles out, (locations 5-PT,6-BC,7-TR),

and 1 TLD control placed in a lead storage cave used for in-transit dose measurement. For 1998 the average monthly gamma readings were: 3.4 mR for the inner ring (site boundary) TLDs; 3.6 mR for the outer ring (3 to

- 4.5 miles out) TLDs; and 3.7 mR for the control TLD locations. The average quarterly gamma readings were: 11.0 mR for the inner ring (site boundary)

TLDs; 11.4 mR for the outer ring (3 to 4.5 miles out) TLDs; and 11.6 mR for the control TLD locations. . The average of the annual gamma readings were: 45.2 mR for the inner ring; 46.1 mR for the outer ring TLD; and 47.3

- mR for the control TLD locations. These results are consistent with historical data. The five on-site TLD locations serve as individual references only and are not included in this evaluation.

z 3

The monthly and quarterly statistical TLD data evaluations were accomplished by comparing the inner ring TLDs and the outer ring TLDs against the control TLD locations. The annual TLD data evaluation was done by a direct comparison of data points only.

In comparing the inner ring TLDs to the control TLDs, station 12-E (0.9 mi SSE site boundary) had the greatest monthly mean, quarterly mean, and annual mean. In comparing the outer ring TLDs to the control TLDs, station 4-SL (Susan Lake, 3.5 mi SE) had the greatest monthly, mean, quarterly mean, and annual mean.

Background and in-transit gamma exposure levels were accounted for and subtracted from the TLD data prior to statistical evaluation. No statistical or evaluating levels were exceeded, and in many instances, cordrol location TLD data was greater than indicator TLD data. BRP Technical specification sensitivities were met.

Environmental gamma doses are measured monthly, quarterly and annually by placement of three TLD badges per designated location. Each Teledyne TLD badge contains a 4-zone CaSO4 phosphor wafer (the wafer also includes an additional backup / reserve read-out zone). Sensitivity for the multi-zone TLDs are 1.0 millirem with a linear response of 0.1 millirem to

.1000 rem.

C. Milk

'A total of 47 individual monthly milk samples were collected from five different dairy farms during 1998. Dairy farms 20-JG or 20-LF,21-DK, and 22-DS serve as indicator locations; and dairy farm 23-BB serves as the control location. In July of 1998, the JGolovich Farm sold his remaining dairy herd. Beginning in August 1998, the LFoltz Farm, (8.0 mi E) was selected as the replacement milk sample station. No samples were collected from either farm in July. The replacement farm was located / identified in August, and sample collection resumed within the thirty day requirement. There were no other problems associated with the quantity or quality of milk samples for the 1998 reporting year.

All analysis results listed in Table 10.2-2 were below LLD. No special or supplemental analysis were required, nor were any Big Rock Technical Specification limits exceeded.

Milk samples are required monthly from each designated collection location (4 total). A two-gallon quantity of raw milk (grab sai,yle) is obtained per ;

collection location in order to meet analytical requirements. Samples are !

. treated with a sodium bisulfite (40 grams per gallon) preservative prior to !

I being sent to Teledyne Brown Engineering for analysis.

D. Lake Water A total of 36 individual monthly lake water composite samples were collected from 3 locations during 1998. Lake water samples from the Lake-in (plant intake) and the Lake-out (plant discharge) are collected daily and composited into monthly samples. Monthly lake water sample composites from Ludington are collected as a control sample.

Evaluation of the monthly lake water analytical results was based on a data means comparison between the samples collected from Lake-in and Lake-out (indicator locations) and the Ludington control location (115 miles SSW of the Plant). The lake water results were also evaluated against BRP Technical Specification reporting limits.

i Tritium and gross beta analyses are required for all lake water samples. l One of the twenty-four indicator location lake water samples had detectable tritium levels with a result of 160 pCi/L. One control lake water samples had detectable tritium levels with a result of 185 pCi/L. The means for gross ,

beta indicator and control locations were 2.6 pCi/L and 2.4 pCi/L, j respectively. I Sr89, Sr90, and gross alpha are required analyses for Lake-out (plant discharge). During 1998 gross alpha was detected in five samples with a mean result of 0.70 pCi/l. Sr89 was not detected in any sample, and Sr90 was detected in four of twelve samples with a mean of 0.80 pCi/L. No BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses required during 1998.

Ludington lake-in, BRP lake-in and BRP discharge samples are collected .

daily for composite into a monthly sample. A one-gallon quantity of sample is sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is necessary.

E. WellWater A total of 24 individual monthly well water samples were collected from the BRP site well (indicator) and the Ludington well (control) during 1998. One control sample was not analyzed as contents leaked out during transit to the Laboratory. Refer to Enclosure A for all sample collection anomaly evaluations. Tritium and gross beta analyses are required for each monthly sample.

Evaluation of the monthly well water analytical results was based on a data means comparison between the BRP site well and the Ludington well samples. No indicator or control well water samples had any detectable tritium. The gross beta means for the indicator and control location were 1.9

o 5

pCi/L and 1.0 pCi/L, respectively. No BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses required during 1998.

A one-gallon grab sample is sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is necessary.

-F. Drinkina Water A total of 24 monthly samples were collected from the Charlevoix Municipal Water System (indicator) and the Ludington lake intake (control) during 1998. Tritium and gross beta analyses are required for each monthly sample.

Evaluation of the monthly drinking water analytical results was based on a data means comparison between the Charlevoix Municipal Water System location and the Ludington lake samples. One control location detected tritium, with a sample analysis result of 165 pCi/L, no indicator samples !

contained detectable tritium. The gross beta means for the indicator and control location were 1.9 pCi/L and 2.4 pCi/L, respectively. No BRP Technical Specification reporting limits were exceeded nor were any

- special/ supplemental analyses required during 1998.

~

The drinking water samples are collected daily for composite into a monthly sample at Charlevoix and monthly grab samples are obtained from the Ludington well. A one-gallon quantity of sample is sent to Teledyne Brown Engineering for analysis. No treatment of the water samples with a preservative is necessary.

G. Crops The collection of food crops / vegetation samples is not required by the BRP Radiological Environmental Monitoring Program Technical Specifications. i There are no regular select locations where food crop samples are i collected, however, several crop samples are usually obtained when in season if available. Cabbage leaves, squash greens, and mustard greens were collected September 01,1998 from DHaklin Farm (2.5 mi ESE).

Evaluation of the crop sample analytical results was direct. All data was combined and reported.- No control location was used.

Only gross beta analyses resulted in any detectable activity. All other results were below LLD. The mean gross beta activity was 6.1 pCi/g in 1998, whicn is comparable to 5.0 pCi/g in 1997 and 4.7 pCi/g in 1996. No l

l J

6 BRP Technical Specification reporting limits were exceeded nor were any special/ supplemental analyses required during 1998.

Food crop samples are obtained seasonally, usually from the E, SE, ESE or SSE meteorological sectors and when specifically requested. When collected, approximately.1 kg of sample is placed in a sealable plastic bag for shipment to Teledyne Brown Engineering. No special treatment of the food crop samples with a preservative is necessary.

H. Sediment .

A total of 12 individual sediment samples were collected from six locations during 1998. Two sediment samples were obtained each from near the BRP discharge channel (1-ST); from Nine Mile Point (2-NM, 3 mi ENE); from the Ludington control station (26-LP,115 mi SSW); from 1/4 mi south of discharge (24-STS); from Mt. McSauba (19-MS, 3 mi W); and from 1/4 mi north of discharge (25-STN).

Evaluation of the sediment analytical results was based on data means comparisons between the BRP samples and the Ludington control samples and the BRP Technical Specification reporting limits. Gross beta was detected in all indicator and control samples. Gross beta means for indicators and control stations were 7.8 pCi/g and 9.0 pCi/g, respectively, Cs-137 was detected in all indicator and control samples. Cs-137 mean for indicator and control locations was 0.17 pCi/g and 0.031 pCi/g respectively.

Mn-54 was detected in four indicator samples with a mean of 0.039 pCi/g.

Co-60 was detected in five indicator samples at 0.12 pCl/g. Mn-54 and Co-

- 60 were not detected in control samples. These results were consistent with lresults from 1996 and 1997 I No BRP Technical Specification reporting levels or action levels were exceeded nor were any other special or supplemental analyses required during 1998.

Sediment samplea are collected semi-annually from designated locations. A one liter quantity grab sample is usually obtained a few yards off-shore. No treatment of the samples with a preservative is necessary prior to shipment j to Teledyne Brown Engineering. l 1 Einh i A total of ten individual fish samples were collected from three locations during 1998. _ Four samples were obtained from BRP site area: 1-ST discharge, and 24-STS 1/4 mile south boundary, and six samples from the Ludington control station (26-LP).

Evaluation of the fish analytical results was based on data means comparisons between the BRP indicator samp!es and the Ludington control samples and the BRP Technical Specification reporting limits. Only gross beta and Cs-137 measurements resulted in any detectable activity. The gross beta means for the indicator and control locations were 2.1 pCi/g and 1.9 pCi/g, respectively. The Cs-137 means for the indicator and control locations were 0.043 pCi/g and 0.015 pCi/g, respectively. Comparison of results between similar species at the different locations resulted in no significant differences.

. No BRP Technical Specification reporting levels were exceeded, nor were any special analyses required during 1998.

Fish samples are collected semi-annually. If possible, at least two different

. fish species (i.e., forage, sport fish, etc.) are sampled semi-annually at designated sample locations. When caught, a one liter quantity of fish sample is prepared for shipment to Teledyne Brown Engineering. Each sample is treated with 10 ml of a 10% formaldehyde solution for preservation.

J. Cravfish A total of three crayfish samples were collected from two different locations during 1998 ST discharge, and 25-STN 1/4 mile north boundary. No l control samples were taken. Evaluation of the crayfish analytical results was based on a data means comparison with the BRP Technical Specification reporting limits.

Radionuclide analyses results are listed in Table HP 10.2-2 for crayfish.

Gross beta was detected in all samples with a mean of 1.56 pCi/g.' No other i isotopes were detected.

No BRP Technical Specification reporting levels were exceeded nor were any special or supplenantal analyses required during 1998.

Crayfish samples are' collected semi-annually at designated locations, however, lack of sample media, inclement weather or rough water

- conditions can either make collecting sufficient sample quantities impossible or wash biota populations out of the immediate sampling vicinity. One liter

. quantities of crayfish are sent to Teledyne Brown Engineering for analysis.

Each sample is treated with 10 ml of a 10% formaldehyde solution for preservation.

)

8 K. Aauatic Biota The aquatic biota category consists of algae and periphyton. A total of ten individual samples were collected from three locations during 1998. Sample ,

types and locations are as follows:

i Algae: Five indicator location samples were obtained, two each from BRP 1-ST discharge, and from 24-STS 1/4 mile south boundary and one from 25-STN 1/4 mile north boundary in 1998. No samples were obtained (not '

available) from other indicator locations or from the Ludington Control Location (26-LP).

Periphyton: Five indicator samples were obtained, two each from BRP (1-ST discharge,25-STN 1/4 mile north boundary and one from 24-STS 1/4 mile -

south boundary)in 1998.

Evaluation of the biota analytical results was based on a data means comparison with the BRP Technical Specification reporting limits.

Analyses are listed in Table HP 10.2-2 for algae. Gamma emitting radionuclides were detectable in all samples. Activity levels were greatest in the samples from the discharge canal area. All other detectable measurements at the 1/4 mile North and 1/4 mile South stations were at levels comparable to the stated lower limit of detection levels. All sample location results are comparable to 1996 and 1997, 1 l

Analyses are listed in Table HP 10.2-2 for oeriohvton. Gamma emitting radionuclides were detectable in all samples. Activity levels were greatest in the samples from the discharge canal area, ST-1, the licensed plant radioactive discharge point. The July 1998 results in the discharge canal area for gross beta,' Mn-54 and Co-60 were higher than previous years, but j lower than pre-operational data, in support of decommissioning activities, '

l there was an increase in batch release activity during the first and second quarters of 1998. Periphyton samples collected in the discharge canal in )

October 1998 indicated gross beta activity returned to nominal levels, concurrent with the decreased batch release activity. All other detectable measurements at the 1/4 mile North and 1/4 mile South stations were at levels comparable to the stated lower limit of detection levels, and comparable to 1996 and 1997 results.

Algae and Periphyton samples / analysis are not required by BRP Technical Specification, there are no reporting or action levels associated with these samples. ' Aquatic biota samples (algae and periphyton) are collected semi-annually at designated locations, however, lack of sample media, inclement weather or rough water conditions can either make collecting sufficient sample quantities impossible or wash biota populations out of the immediate sampling vicinity. One liter quantities of biota are sent to Teledyne Brown

r 9

Engineering for analysis. ' Each sample is treated with 10 ml of a 10%

' formaldehyde solution for preservation.

L. Broad Leaf Veaetation No broad leaf vegetation samples were collected from the surrounding BRP environs during 1998. The collection of broad leaf vegetation samples serves as a backup and/or alternative sampling media in case any milk sampling location (s) become(s) unavailable. One of the milk samples was not collected in July as the supplier went out of business on short notice.

Broad leaf vegetation samples were not collected because the replacement dairy farm was located within the thirty day requirement.

M'.'Gaseous and Liould Radwaste Effluent Comoosite Samoles Although not a direct reporting component in the BRP Annual Radiological Environmental Monitoring Report, results of the gaseous and liquid monthly radwaste effluent composite samples are evaluated against overall environmental trending data. This evaluation is the basis for determining isotopic dispersion and deposition patterns within the surrounding environs of BRP. All isotopic values are compared to BRP Technical Specification reporting levels.

Both the gaseous and liquid radwaste effluent composite samples are collected monthly and sent to Teledyne Brown Engineering for analysis.

The liquid effluent composite sample is based on a specific volume amount of sample collected per total batch volume released. As noted in Enclosure A, for months in which there were no liquid batch effluent releases no sample is sent to Teledyne Brown Engineering. The gaseous radwaste effluent monthly composite sample results are based on analyzing four or five weekly stack gas filters. No special sample treatment with a preservative is required prior to laboratory analysis.

Ill. Assessment of Bia Rock Point's Operational Environmental Imoact I In reviewing the 1998 Big Rock Point radiological environmental monitoring data and comparing it to previous operational and pre-operational data, all trending parameters continue to indicate that the operation of Big Rock Point has minimal environmental impact. Most radionuclide activity is at environmental" background" levels. Evidence of an overall environmental isotopic build-up (attributable to Plant effluent) remains negligible as well. In most instances, sample analytical results were below previously established environmental background levels. Station ST-1 is the licensed plant radioactive

n.

r 10 discharge point, and as expected, this station is normally the indicator location with the highest annual mean when comparing analytical results.

1998 LAND USE CENSUS TPNeal, Palisades MLG98*019 CC TGoble, Big Rock DCC:740/72*10*03/LP The attached tables are the results of the Big Rock Point Land Use Census conducted by MLGrogan and TRSchlueter on September 16,1998. Table 10.11-1 references the distance from Big Rock Point to the nearest residence, garden, beef / dairy cattle and goat per meteorological sector within a (5) five mile radius of the plant. Table 10.11-2 identifies the locations of the nearest residence, of all gardens (greater than 500 square feet) within a three (3) mile radius of the plant, and all beef / dairy animals within a five (5) mile radius of the plant. Table 10.11-3 lists the critical receptor locations used in .

calculation of offsite doses by the GASPAR computer program.

The 1998 land use survey was performed to meet current Big Rock Technical Specification Requiremets (13.2.2). The Decommissioning Tech Specs no longer require a land use survey, but have not gone into effect to date in 1998.

There were no changes to critical receptor locations from the 1997 Land Use Survey.

The propo' sed Table 1.4 in Section 2 of the new ODCM is correct, new Tables 1.4 and 1.4a were not revised and are not included.

This land use census is more detailed than required. Big Rock Point Technical Specification 13.2.3 requires the identification within a distance of (5) five miles the location in each of the (9) nine overland meteorological sectors of the nearest milk animal, the nearest residence and the nearest garden greater than 500 square feet producing broad leaf vegetation. The land use census shall also identify within a distance of 3 miles the locations in each of the overland sectors of d milk animals and

. d gardens of greater than 500 square feet producing broad leaf vegetation.

Prior to conducting the Big Rock Point 1998 Land Use Census the Charlevoix County

Agricultural Extension Office was contacted as required by Procedure HP 10.11. If you have any questions, please contact me.

1.0 INTRODUCTION

The following constitutes the final,1998 Monthly Progress Report for the Radiological Environmental Monitoring Program conducted at the Consumers Energy Company, Big Rock Nuclear Generating Plant. Results of completed analyses are presented in the attached tables.-

. For gamma isotopic analyses, a spectrum is collected covering an energy range from 80 to 2048 kev.

Specifically included are Mn-54, Fe-59, Co-58, Co-60, Zn-65, Zr-95, Nb-95, I-131, Ba-La-140, Cs-134 and Cs-137. Naturally-occuring gamma-emitters, such as K-40 and Ra daughters, are frequently detected but not listed here. Data listed as "<" are at the 4.66 sigma level, others are 2 sigma.

All concentrations, except gross beta, are decay corrected the time of collection.

All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples.

l APPENDIX A INTERLABORATORY COMPARISON PROGRAM RESULTS NOTE: Teledyne's Midwest Laboratory participates in intercomparison studies administered by U.S. EPA

- Environmental Monitoring Systems Laboratory, Las Vegas, Nevada. The results are reported in Appendix A.~Also reported are results of International Intercomparison and Teledyne testing of

'IT.D's, as well as, in-house spikes, blanks, duplicates and mixed analyte performance evaluation

. program results. Appendix A is updated four times a year; the complete Appendix is included in March, June, September and December monthly progress reports only.

1 January,1998 through December,1998

Annendix A Interlaboratory Comparison Proeram Results I

Teledyne Brown. Engineering Environmental. Services Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of it's quality control program in December 1971. These programs are operated by agencies which supply environmental type samples (e.g., milk or water) containing concentrations of radionuclides j

known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent check on the laboratory's analytical procedures and to alert it to any possible problems.

Participant laboratories measure the concentration of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values to the participant laboratories and specifies control limits. ' Results consistently higher or lower than the known values or outside the controllimits indicate a need to check the instruments or procedures used.-

The results in Table A-1 were obtained through participation in the environmental sample crosscheck program for milk, water and air filters during the past twelve months. Data for previous years is available upon request.

This program is conducted by the U.S. Environmental Protection Agency Office of Research and Developement National Exposure Research Laboratory Characterization Research Division-Las Vegas, Nevada.

The results in Table A-2 were obtained for Thermoluminescent Dosimeters (TLDs), via various i InternationalIntercomparisons of Environmental Dosimeters under the sponsorships listed in Table A-2.

Also Teledyne testing results are listed.

~

Table A-3 lists results of the analyses on in-house " spiked" samples for the past twelve months. All -

samples are prepared using NIST traceable sources. Data for previous years available upon request. l

)

Table A 4 lists results of the analyses on in-house " blank" samples for the past twelve months. Data for l

previous years available upon request.

' Table A-5 list results of the in-house " duplicate" program for the past twelve months. Acceptance is based Lon the difference of the results being less than the sum of the errors. Data for previous years available uPon request.

The results in Table A-6 were obtained through participation in the mixed analyte performance evaluation program.:

The results in Table A-7 were obtained through participation in the Environmental Measurement Laboratory Quality Assessment Program.

Attachment A lists acceptance criteria for " spiked" samples.

Out-of-limit results are explained directly below the result.

The Environmental Measurements Laboratory provides the following nuclear species : Air Filters, Soil, Tissue, Vegetation and Water. Teledyne does not participate in the Tissue program.

Results are reported in Bq/L with the following exceptions: Air Filter results are reported in Bq/ Filter', Soil results are reported in Bq/Kg, Vegetation results are reported in Bq/Kg The results of elemental Uranium are reported in ug/filtef', g, or ml.

i

Teledyne results are reported as the mean of three determinations

standard deviation.

d 'Ihe EML result listed is the mean of replicate determinations for each nuclide*the standard error of the mean. l

' The control limits are reported by EML and are established from percentiles of historic data distributions l (1982-1992). The evaluation of this historic data and the development of the controllimits is presented in DOE l

report EML-564.

APPENDIX B I

l DATA REPORTING CONVENTIONS l l

f B-1

Data Reporting Conventions 1.0. l All activities except gross alpha and gross beta are decay corrected to collection time or

. the end of the collection period.

2.0. Single Manaurements Each single measurement is reported as follows:

xis where x = value of the measurement; s = 2e counting uncertainty (corresponding to the 95% confidence level).

In cases where the activity is found to be below the lower limit of detection L it is reported as

<L where L = the lower limit of detection based on 4.660 uncertainty for a background sample.

3.0. - Duplicate analyses 3.1 Individual results: xi i s1 x2

s2 Reoorted result: x s where x = (1/2) (xi + x2) s =_ (1/2) k sf + s!

3.2. Individual results: <Li

<L2 Reoorted result: <L where L = lower of Liand L2 3.3. Individual results: x

s

<L Reoorted result:- x i s .if x L;

<L otherwise B. 2

4.0. Comoutation of Averaces and Standard Deviations l

4.1 Averages and standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average i and standard deviation s of a set of n numbers x3, x2. . . xn are defined as follows:

i= x-(x- x)2

)

s= n-1 4.2 Values below the highest lower limit of detection are not included in the average. )

4.3 If all of the values in the averaging group are less than the highest LLD, the highest LLD is reported.

1 I

4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported.

4.5 In rounding off, the following rules are followed:

4.5.1. If the figure following those to be retained is less than 5, the figure is dropped, and the retained figures are kept unchanged. As an example,11.443 is rounded off to 11.44.

l 4.5.2. If the figure following those to be retained is equal to or greater than 5, the figure is dropped and the last retained figure is raised by 1. As an example,11.445 is rounded off to l 11.45. l I
