The Explosive Compound RDX May Be the Greatest Threat to the US’s Health

RDX is increasingly turning up in drinking water supplies near military sites.

The United States has built the most powerful military in the world. That fact has come at a largely unknown cost. The testing and disposal of the nation’s weapons here in the US have poisoned drinking water supplies, rendered millions of acres of land unsafe or unusable, and jeopardized the health of often unwitting Americans.

ProPublica months ago began investigating the scope of the environmental problems caused by the US military on domestic soil. What we found was arresting. The Pentagon has catalogued more than 40,000 contaminated sites across US states and territories, and it has so far spent more than $40 billion attempting to clean them up. We have found no other single entity — corporation, government agency or individual — responsible for so much environmental degradation. The total amount of land contaminated by the military is larger than the state of Florida. Thousands of sites remain dangerously polluted and fenced off, awaiting the government’s attention. Thousands of others have already been returned to public use — for parks, housing and schools — in some instances without thorough cleanups.

Faced with these liabilities, the Pentagon has routinely sought to minimize its responsibility for fixing its environmental problems. It burns hazardous waste and explosives because it’s the cheapest way to dispose of them, even though the burning process has been outlawed for most American industries since the 1980s. It employs contractors to dispose of hazardous waste and clean up toxic sites, then claims it is not responsible when some of those contractors commit fraud, improperly handle toxic material, or cut corners on cleanups. It has in some cases explicitly refused to cooperate with the US Environmental Protection Agency and let dangerous sites linger unaddressed.

But perhaps nothing better exemplifies the Pentagon’s approach to its pollution problem than the story of RDX, one of the world’s most powerful conventional explosives. RDX was developed by the US military during World War II. It is now believed by many to cause cancer, and is increasingly turning up in drinking water supplies near military sites across the country. As the human health and environmental dangers of RDX have become known, ProPublica’s investigation found that the Pentagon has resisted scientific evidence that it causes cancer, interfered with federal and state efforts to clean up RDX-contaminated lands, and even pressed Congress to re-write American environmental laws so as to not apply to RDX contamination.

Our most important fundraising appeal of the year

December is the most critical time of year for Truthout, because our nonprofit news is funded almost entirely by individual donations from readers like you. So before you navigate away, we ask that you take just a second to support Truthout with a tax-deductible donation.

This year is a little different. We are up against a far-reaching, wide-scale attack on press freedom coming from the Trump administration. 2025 was a year of frightening censorship, news industry corporate consolidation, and worsening financial conditions for progressive nonprofits across the board.

We can only resist Trump’s agenda by cultivating a strong base of support. The right-wing mediasphere is funded comfortably by billionaire owners and venture capitalist philanthropists. At Truthout, we have you.

We’ve set an ambitious target for our year-end campaign — a goal of $250,000 to keep up our fight against authoritarianism in 2026. Please take a meaningful action in this fight: make a one-time or monthly donation to Truthout before December 31. If you have the means, please dig deep.
