U.S. Army Center for Health Promotion and Preventive Medicine

The lineage of the U.S. Army Centerfor Health Promotion and Preventive Medicine (USACHPPM) can be traced back over 50years. This organization began as the U.S. Army Industrial Hygiene Laboratory, established during the industrial buildup for World War II, under the direct supervision of the Army Surgeon General. Its original location was at the Johns Hopkins School of Hygiene and Public Health. Its mission was to conduct occupational health surveys and investigations within the Department of Defense's (DOD's) industrial production base. It was staffed with three personnel and had a limited annual operating budget of three thousand dollars.

Most recently, it became internationally known as the U.S. Army Environmental Hygiene Ageney (AEHA). Its mission expanded to support worldwide preventive medicine programs of the Army, DOD, and other Federal agencies as directed by the Army Medical Command or the Office of The Surgeon General, through consultations, support services, investigations, on-site visits, and training.

On 1 August 1994, AEHA was redesignated the U.S. Army Centerfor Health Promotion and Preventive Medicine with a provisional status and a commanding general officer. On 1 October 1995, the nonprovisional status was approved with a mission of providing preventive medicine and health promotion leadership, direction, and services for America's Army.

The organization's quest has always been one of excellence and the provision of qualitp service. Today, its goal is to be an established world-class center of excellence for achieving and maintaining afit, healthy, and ready force. To achieve that end, the CHPPM holds firmly to its values which are steeped in rich military heritage:

* Integrity is the foundation * Excellence is the standard

* Customer satisfaction is the focus * Its people are the most valued resource

* Continuous quality improvement is the pathway

This organization stands on the threshold of even greater challenges and responsibilities. It has been reorganized and reengineered to support the Army of the future. The CHPPM now has three direct support activities located in Fort Meade, Maryland; Fort McPherson, Georgia; and Fitzsimons Army Medical Center, Aurora, Colorado; to provide responsive regional health promotion and preventive medicine support across the U.S. There are also two CHPPM overseas commands in Landstuhl, Germany and Camp Zama, Japan who contribute to the success of CHPPM's increasing global mission. As CHPPM moves into the 21st Centugy, new programs relating to

fitness, health promotion, wellness, and disease surveillance are being added. As always, CHPPM stands firm in its commitment to Army readiness. It is an organization proud of its fine history, yet equally excited about its challenging future.

EXECUTIVE SUMMARY INDUSTRIAL AND ENVIRONMENTAL RADIATION SURVEY

NO. 27-MH-8260-99 U.S. ARMY JEFFERSON PROVING GROUND

MADISON, INDIANA 26-30 APRIL 1999

I. PURPOSE. This survey was performed to assist in your efforts to implement the Nuclear Regulatory Commission (NRC) approved Environmental Monitoring Program (EMP) in accordance with (IAW) NRC License Number SUB-1435 and its amendments. It requires the examination of the fate and transport of depleted uranium (DU) from the DU impact area at Jefferson Proving Ground.

II. CONCLUSION. A review of the EMP sampling results for April 1999 indicated the following:

A. Subsequent to the identification of a single elevated sample collected in the restricted area along the DU firing line (S8) during the last JPG monitoring trip, five soil samples were collected in the sample grid. The single sample required semiannually in that sample grid was also collected. The five samples were analyzed and the laboratory values were averaged and found to have concentrations of DU in excess of the action level requiring further investigation, but less than that requiring NRC notification. The single annual sample also had concentrations of DU in excess of the action level, but did not require NRC notification.

B. The overall EMP is very sound and is being conducted IAW current regulatory requirements for radiation protection.

III. RECOMMENDATION. Further investigation into the extent of the DU contamination in the area along the DU firing line should be continued. The U.S. Army Test and Evaluation Command Radiation Safety Officer has been notified of the six samples containing elevated levels of DU.

•35 picocurie per gram (pCi/g) - no corrective action.

) 35 pCi/g - collect 5 additional samples in a 1 meter square grid.

If average is still ) 35 pCi/g, decontaminate to levels of 35 pCi/g.

* Sample locations along the lines of fire:

( 100 pCi/g - no corrective action.

100-300 pCi/g - collect 5 additional samples in a 1 meter square grid.

If average is still ) 100 pCi/g, investigate to determine reason for the high level.

) 300 pCi/g is verified, investigate to determine reason

for the high level and notify the NRC.

(2) Surface & Ground Water:

Depleted Uranium [Note: Title 10, Code of Federal Regulations (CFR), Part 20, Appendix B (effluent concentrations for water) limit is 3.0 x 10-1 picocurie per milliliter (pCi/ml)]:

( 1.5 x 10-1 pCi/ml - no corrective action.

) 1.5 x 10-1 pCi/ml - resample: if results are ) 1.5 x i0-1 pCi/ml, investigate to determine reason for the high level and notify the NRC.

3. Basis for Action. When action levels are exceeded, an evaluation of cause will be performed by the TECOM Radiation Protection Officer (RPO). The TECOM RPO will provide a report

of findings to the licensee's Radiation Control Committee. Based on their determination, recommendations to the Commander on corrective action will be made.

D. Records and Reports.

1. Records were available to show previous locations sampled as part of the EMP.

2. Instrumentation used for this project was calibrated at the required frequency.

E. Survey Results.

1. Soil Samples. The USACHPPM used the dry procedure for preparing the samples for analysis. All soil sample locations and exposure results are presented in Appendix D. The soil sample number S8, located directly along the firing line and collected during the October 1998 radiation survey performed by USACHPPM was determined to have DU concentrations between 100-300 pCi/gm. Per the action level criteria for the restricted area, five additional samples were collected within a 1 meter square grid. The samples numbered S8C and S8 (N, S, E and W) were analyzed by the USACHPPM Directorate of Laboratory Sciences (DLS). The gamma spectroscopy laboratory analysis for sample numbers S8C and S8 (N, S, E and W) identified contamination in the samples from a minimum of 140 ± 10 pCi/g to a maximum of 170 pCi/g of thorium-234 (Th-234). Assuming that the radioactive daughter of uranium-238 (U-238), Th-234, is at equilibrium with U-238, the data indicates U-238 is within the criteria requiring an investigation to identify why this condition exists. This condition exists due to the proximity of the sample area to the DU firing line. The firing line lies within the impact area, so access by the general public to this area is restricted. No further action is required. Soil sample Laboratory analysis results are presented in Appendix E.

2. Sediment Samples. All sediment sample locations are presented in Appendix D. Analysis of the sediment samples resulted in no recommended corrective action required. Laboratory analysis of sediment sample results are presented in Appendix E.

water sample results indicated no corrective action required as stated in the EMP. Laboratory analysis of surface water sample results are presented in Appendix E.

4. Ground Water Samples. All ground water sample locations are presented in Appendix D. Analysis of the ground water samples resulted in no corrective action required as stated in the EMP. Laboratory analysis of sediment sample results are presented in Appendix E.

5. External Radiation Monitoring Results. Radiation exposure measurements were taken at each area where soil samples were collected, of nearby areas where ground water samples were collected and in the area where sediment samples were collected. All radiation exposure results are presented in Appendix D. The radiation exposure measurements ranged from a low of 3.5

microroentgen per hour (gR/hr) to a high of 17.1 gR/hr.

VI. DISCUSSION. Five soil samples numbered S8C and S8 (N, S, E and W) and one soil sample required for the semiannual investigation were obtained along the DU firing line approximately 0.5 mile east of the intersection between C-Road and East Recovery Road. The background exposure rate measurements for this area ranged from approximately 10 to 15 gR/hr.

VII. CONCLUSION. A review of the EMP sampling results for April 1999 indicated the following:

A. Six soil samples within a 10 meter square grid in the restricted area exceeded the DU contamination action level for soil as stated in the USACHPPM's SOP for the DU sampling program Appendix C. NRC notification is not required.

B. The overall EMP was very sound and was being conducted IAW current regulatory requirements for radiation protection.

Indust and Env Radn Surv No. 27-MH-8260-99, JPG, Madison, IN, 26-30 Apr 99

6. Sampling media will total 6 soil, 8 sediment, 8 surface water, and 11 ground water samples plus quality control samples. Split, duplicate and/or blank samples will be submitted as appropriate.

a) Impact Area Soil Sample Locations. Six sample locations will be located, four at the corners of the trapezoidal impact field and two near the center along the trajectory axis of the field (see Figure 2). These samples will be used to determine if weathering of expended tank penetrator projectiles is occurring. Samples will be taken semiannually, unless action level is exceeded, and quarterly as long as corrective action is required.

b) Sediment Samples. In each of the two streams (Big Creek & Middle Fork Creek), three sediment samples will be taken downstream and one upstream, as a control, from the impact area for the DU penetrator programs. (see Figure 3). These samples will be taken to determine if any DU particles have entered the stream. Samples will be taken from low spots or bends, when possible. One sample will be at the point where drainage from an impact area initially enters the stream. One sample will be from a point located midway between the initial sample and the installation boundary. The final downstream sample will be taken at the installation boundary. Samples will be taken semiannually, unless the action level is exceeded, and quarterly as long as corrective action is required.

c) Water Samples (See special instructions in section 9.

1) Surface Water. In each of the two streams (Big Creek & Middle Fork Creek), three water samples will be taken downstream and one upstream, as a control, from the impact area for the DU penetrator programs to determine the migration of soluble uranium compounds (see Figure 3). One sample will be at the point where drainage area enters the stream. One sample will be from a point located midway between the initial sample and the installation boundary. The final downstream sample will be taken at the installation boundary. Samples will be taken semiannually, unless the action level is exceeded, and quarterly as long as corrective action is required.

Indust and Env Radn Surv No. 27-MH-8260-99, JPG, Madison, IN, 26-30 May 99

2) Ground Water. Eleven ground monitoring wells have been installed (see Figure 1). Ground monitoring wells are approximately 40 feet deep. If DU migrates to the ground water, it is expected to be detected in the three wells in the impact area first. The two wells located near the south perimeter are considered to be background samples because they are upstream from the impact area. Samples are collected semiannually. If action levels are exceeded, quarterly sampling will be initiated as long as corrective action is required.

7. Methodologies for sampling used for this special project will be following the guidance outlined in USAEHA Technical Guide No. 155, Environmental Sampling Guide, February 1993.

Sample Contamination Management.

a) Disposable gloves and splash protective apparel (i.e., saranex aprons, eye protection) will be worn when applicable. Gloves will be changed between each sample collection.

b) Sample collection equipment will be washed with deionized or distilled water and dried between each sample. All disposable equipment will be used one time only. Equipment washing will be done over the sample collection point prior to moving to the next sample location. Disposal will be IAW the ERM for JPG.

8. Water monitoring wells will be purged using bailers prior to sampling. Purging and sampling operations will comply with the ERM Plan for JPG. Sampling waste will be handled IAW the ERM.

9. Sample analysis of all environmental samples will be performed through the USACHPPM, Radiologic, Classic & Clinical Chemistry Division (RCCCD), Aberdeen Proving Ground, Maryland.

a) Samples will be analyzed IAW USACHPPM, RCCCD protocols and procedures. All environmental samples will be coordinated with the TECOM RPO for disposal instructions.

Indust and Env Radn Surv No. 27-MH-8260-99, JPG, Madison, IN, 26-30 May 99

b) The Quality Assurance for laboratory instruments will be performed by RCCCD, USACHPPM.

10. Inform RCCCD when shipping back of water samples. All collected samples will be placed in self-sealing containers and shipped to USACHPPM via Federal Express. Water samples must arrive back at CHPPM no later than 4 days from sampling time in order for holding time not to be exceeded. No filtering of sample or preservative will be performed in the field. The RCCCD must test for dissolved DU in the water.

11. All laboratory samples will be controlled (chain-ofcustody) IAW USAEHA TG No. 155, Appendix E.

12. Action Levels:

a) Every effort will be made to maintain radiation exposures and releases of radioactive and nonradioactive toxic metals to unrestricted areas as low as is reasonable achievable (ALARA).

b) The following criteria for the restricted area will be used to limit (DU) exposure.

1) Soil:

* Perimeter and background samples:

•35 pCi/g - no corrective action.

) 35 pCi/g - collect 5 additional samples in a 1 meter square grid.

If average is still ) 35 pCi/g, decontaminate to levels of 35 pCi/g.

1. Reference USACHPPM Report 466147, DLS Job ID 9B2076, 27 May 99.

2. This is a corrected copy of the previous report.

3. Provided are results of analyzing twenty-one water and twenty-one sedimentlsoil samples for uranium.

4. aNochainofý-custody shee was provided for soil samples with laboratory numbers B3474 through B3483.

5. The water samples were analyzed for total uranium by fluorometric analysis. Water samples with laboratory numbers B3251 and B3258 were analyzed in duplicate to demonstrate the precision of the procedure. The duplicate results are listed with the suffix dup.

6. The sediment/soil samples were analyzed by gamma spectroscopy for thorium-234 the progeny of uranium-238. Thorium-234 presence is based on the detection of the 63 and 93 keV peaks. Samples with laboratory numbers B3276 and B3479 were analyzed in duplicate to demonstrate the precision of the procedure. The duplicate results are listed with the suffix laboratory dup.

7. After review of results, if additional analysis is required, please contact the laboratory.
