Range-Land Stewardship Starts at the Berm: How Outdoor Ranges Are Reclaiming Lead-Contaminated Soil

When Lincoln Gun Range in Placer County dug into their pistol berms for a routine rebuild, they found twelve tons of pure lead and enough contaminated soil to fill 400 dump trucks. Pennsylvania Game Commission pulled 100,000 pounds of lead from 47 state ranges, using chemical conversion to make soils non-hazardous for berm replacement. Nobody had a gun to their heads. The EPA wasn't knocking. These were clubs that saw what was coming and decided to deal with it on their own terms.

The numbers tell the story your members don't want to hear. Lead is the primary soil contaminant at outdoor shooting ranges, with concentrations often reaching tens of thousands of parts per million in soils behind targets and impact berms. If your range has been running for fifteen years, odds are your berm soils are holding more than 1,000 mg/kg, well past the EPA's 400 mg/kg threshold. Some U.S. sites have tested as high as 233,142 mg/kg. A single.30-30 round—approximately 8.1 grams of lead—can contaminate approximately 370 cubic feet of soil to Superfund levels. Run that math over twenty years and you're sitting on contamination roughly 9.6 times what triggers federal cleanup action.

Most clubs find out they have a problem during routine testing before an expansion, after a neighbor complains, or when the berms need rebuilding and ignorance stops being a defense. If your berms are sand or gravel, lead migrates faster and increases the potential to contaminate water supplies. Clay holds it more densely but makes removal harder. As bullets and pellets dissolve over time, rain leaches lead through the soil, potentially creating a contamination plume in groundwater that can poison wells and other water sources. When soil leaches more than 5 mg/L under the TCLP test, it becomes hazardous waste under RCRA, and your disposal costs go through the roof. Lead from shooting ranges is more bioavailable than lead from most industrial contamination, meaning it poses greater health risks than concentration numbers alone suggest.

Berm remediation typically runs $30,000 to $50,000 for excavation and treatment, money most clubs don't have sitting in reserve. Strathcona Shooting Range in Edmonton completed $3.4 million in remediation—versus an estimated $7 to $9 million—through thorough pre-planning, removing 58,861 tons of non-hazardous soil and meeting Tier 1 residential guidelines. Without proper treatment, untreated soil classified as hazardous waste dramatically increases costs and liability.

The standard process involves excavating lead-impacted soil, mechanically separating lead bullets via density and size-based systems, treating soil with stabilization agents, performing confirmatory TCLP testing, and reconstructing the berms. Mechanical screening pulls out large bullet fragments but can introduce metallic lead into fine soil particles if not managed carefully. Combined approaches using heavy particle concentrators with orbital screening and secondary concrete treatment have achieved 91% lead removal rates. Stabilization technologies like ECOBOND or Blastox 215 can reduce disposal costs by 50% by rendering soil non-hazardous. Adding lime and phosphate during treatment can stabilize lead and reduce its migration to groundwater. Some ranges have replaced soil berms with limed sand berms, which significantly reduced total soil lead content from 277 to 57 mg/kg over 11 months. Munitions fragments recovered during sifting are recyclable and exempt from hazardous waste reporting. Lead recovery companies guarantee 60 to 80 percent of the Lead Market Exchange price for recovered lead, providing some revenue offset but never enough to break even. Bucket-based bullet traps like Bullet Bank reduce lead removal to minutes with minimal human contact, concentrating lead in buckets and avoiding dispersed soil contamination. Willow Slough Wildlife Area range in Indiana, managed by the state DNR, focused on berm reconstruction and lead removal to prevent safety and environmental issues while restoring operational configuration.

The most critical step in preventing lead migration is shielding berms from rainfall, as ordinary rain saturates and erodes berms, carrying lead into groundwater. Maintaining soil pH between 6.5 and 8.5—mildly alkaline—helps limit lead migration, as both acidic and alkaline extremes increase chemical activity and migration rates.

Some clubs looked at the economics and switched to non-toxic shot or bullets—copper, steel, frangible—to prevent future accumulation rather than face repeated remediation cycles. Lead exposure at ranges originates not only from projectiles but also from primers, which contain approximately 35 percent lead styphnate and lead peroxide. California requires non-lead ammunition when taking any wildlife with a firearm anywhere in the state, effective July 2019, following Assembly Bill 711 in 2013, and has passed legislation to ban all lead ammunition at indoor and outdoor gun ranges statewide.

Getting member buy-in is often harder than the remediation work itself—and where most range officers lose sleep. Resistance stems from legitimate concerns: non-toxic ammo can cost significantly more, performance differences are real, and availability is limited for certain calibers or shotgun bores. The clubs that built consensus used voucher and ammunition swap programs, transparent education on environmental benefits, and open communication rather than mandates. Leadership framed stewardship as protecting the club's long-term access and autonomy, not as compliance with external pressure. The transition requires either strong advocacy from conservation-minded members with political capital, or sustained policy engagement combined with user education to overcome entrenched resistance. Clubs that actively recover lead or switch to non-toxic ammunition have the lowest risk of environmental litigation.

The regulatory and legal landscape is waiting for clubs to slip. The EPA published Best Management Practices for Lead at Outdoor Shooting Ranges guidance in 2001, revised in 2005, and can require investigation and remediation under CERCLA authority if contamination poses unacceptable risk to human health or the environment. Outdoor firing ranges are exempt from EPA's new lead reporting requirements and many federal pollution control laws, but exemptions don't prevent lawsuits or state action—they just mean you won't see it coming. In a Maryland case, a facility settled a citizen lawsuit by agreeing to remove lead from soil and wetlands and redirect shooting stations away from wetlands. OSHA or EPA fines for firing range violations typically range from $250,000 to $500,000. The driving force for most remediation projects is avoidance of these severe consequences: regulatory fines, citizen lawsuits under RCRA, and multi-million dollar cleanup costs associated with abandoned lead.

Clubs that address contamination proactively—before the EPA, neighbors, or litigation forces their hand—earn credibility with local zoning boards, neighbors, and conservation groups, and negotiate from strength when pressure does arrive rather than responding defensively from a position of violation. Nearly all measured blood lead levels in recreational shooters exceed the CDC/NIOSH reference level of 5 micrograms per deciliter, with women and children among those at special risk. Outdoor firing ranges are estimated to put more lead into the environment than any other U.S. industry except metals mining and manufacturing.

The clubs that treat lead management as part of the job—not a crisis or a political fight—are the ones building resilience for the next generation of shooters. Stewardship isn't virtue signaling; it's the operational cost of keeping land open for shooting when neighbors, regulators, and litigation are all watching. The clubs making hard decisions now—spending money, educating members, changing practices—are the ones who'll still have ranges in twenty years.
