The invention pertains to a method for reducing the leaching of lead from lead projectile impact area acting to collect or stop such projectiles. The method includes contacting the lead projectile impact area with a seed of dry granular lead stabilizing agents. The seeding or coating of lead stabilizing agents provides a means to stabilize lead in the bullet/shot impact area while also allowing for future lead bullets, fragments, or lead shot fired into the soil to be stabilized upon contact with the lead stabilizing agent seeds or contact with rainwater leaching through the lead stabilizing agent seeds produced from the projectile coating, or excess seed from the lead shell projectiles. This method eliminates the need to remove or re-treat range soils and greatly reduces the environmental and health risks associated with the use of lead as projectiles in the open environment as well as at control trap ranges.
A method of stabilizing lead in a lead projectile impact area, comprising incorporating at least one dry granular lead stabilizing agent within and/or upon the surface of a projectile impact area in an amount effective in reducing the leaching of lead from lead projectile to a level no more than 5.0 ppm lead as determined in an EPA TCLP test performed on the projectile impact area soils or material receiving the projectile as set forth in the Federal Register, vol. 55, no. 126, pp. 26985-26998 (Jun. 29, 1990).
A method for preventing lead contamination from a material receiving a lead projectile, comprising stabilizing the projectile impact material prior to its use, such that the lead does not leach therefrom upon contact with the projectile.
