Constituent
Comment
Lead
Primary constituent of a projectile
Lead Styphnate/Lead Azide
Primer constituent
Antimony
Increases hardness.
Arsenic
Present in lead. A small amount is
necessary in the production of small shot
since it increases the surface tension of
dropped lead, thereby improving lead
shot roundness.
Copper Bullet Core Alloy
Increases hardness.
Tin
Increases hardness.
Constituent
Comment
Copper
Jacket alloy metal
Zinc
Jacket alloy metal
Iron
Iron tips on penetrator rounds
PAHs (Polycyclic Aromatic
Hydrocarbons)
Concentration of PAHs in clay targets
varies from one manufacturer to the
next, but may be as high as 1,000mg/kg.
Existing studies show that PAHs are
bound within the limestone matrix of the
target and are, therefore, not
bioavailable.

 Lower Cleanup Goals = Higher Costs
Remediation

Disposal
 Off-Range Disposal
 Toxicity Characteristics Leaching Procedure
(TCLP) Testing Warranted to Define Waste Stream
Classification
Hazardous or Non-Hazardous?
 Haz Soil Can be Treated to Become Non-Haz
Physical Separation
Stabilization/Solidification
Soil Washing
Chemical Extraction

Soil Reuse
 No Testing Required: On-Site Use
 Physical Separation of Bullet Fragments
 Berm Reconstruction
 Other Uses within Range Boundary
 Side/Wing Walls
 Off-Site Use
 Testing Required, Treatment Good Probability
 Render and Prove Non-Haz
 Show Totals Meet State Criterias
 Fill Materials

Soil Recycling
 Chemically Treat/Utilize Soils in a Product
 Rendered Inseparable by Physical Means
 Meets Universal Treatment Standards
 Road Base Emulsions/Materials

Physical Separation
 Use for On-Site Management or Off-Site Disposal
 Dry Screening/Sifting
 Bullet Fragment Removal/Recycling
 Lower Limit of ¼ inch

Stabilization/Solidification
 Stabilization
 Phosphates, Sulfates, Hydroxides, and Carbonates
 Solidification
 Portland Cement, Cement Kiln Dust
 Use for On-Site Management
 Lower/Control Solubility, Leaching to
Ground/Surface Water, and Bioavailability/Risk
 Use for Off-Site Disposal
 Render Non-Hazardous to Lower Disposal Costs

Stabilization/Solidification - continued
 Pros:
 Off-Site Disposal of Non-Haz Soils Reduces
Tipping Fees
 Risk Remains with Land Owner and Not
Transferred to a Landfill for Potential Future
Liabilities if Soils Remain On-Site

Stabilization/Solidification - continued
 Cons:
 If Volume is Small, Costs to Perform Option do
not Outweigh Savings from Non-Haz Landfill
 No Reduction in Total Metal Concentrations
 Material is Heavily Bulked
 Land Use Controls Warranted if On-Site
 RCRA Permit May be Needed by State
