Explore a timeline of Brownfields and land revitalization programs

Analyzing brownfield cleanup to explain why bioremediation aligns with environmental justice

This designation applies to sites contaminated by industrial or commercial activity and that are either underutilized or abandoned. Common in economically disadvantaged communities of color, brownfields pose risks to human health and can be costly to restore. Bioremediation can be a more affordable solution that creates in-demand employment pathways in environmental science, regenerative agriculture, and ecological restoration for community members.

Known as Superfund sites, these toxic locations undergo long-term cleanup to remove hazardous waste, protect health, and restore land for safe reuse. As of 2025, the EPA lists around 1,300 active Superfund sites on its National Priorities List, with more than 450 cleaned and removed since 1980.

Why bacterial bioremediation may help counter the negative effects of past chemical solutions

Molecules such as DDT, a synthetic insecticide, and PFAS—"forever" chemicals used to make products resistant to heat, water, and grease—have historically been used across various industries but are now known to be harmful. Microbes that can convert some of these substances into nontoxic products, such as water and carbon dioxide, have already been identified, with ongoing research to find others.

The use of fungi to detoxify land and water—a process known as mycoremediation—has been used to clean up natural resources affected by the 2025 California wildfires.

The EPA works directly with Indigenous nations to protect native lands

Through the National EPA-Tribal Science Council, the agency works directly with federally recognized tribes, supporting air and water monitoring, pollution cleanup, and environmental restoration. Special grant programs also exist to enable tribes to develop their own environmental programs and enhance their technical capacity.

The billion-dollar ghost town in Baltimore

As a Rust Belt city looking to revitalize its economic core, Baltimore, Maryland, sought big investments from developers and municipalities. The so-called Baltimore Peninsula is a billion-dollar neighborhood in south Baltimore initially prompted by the investment of Under Armour CEO Kevin Plank. In 2025, the glossy, grand urban neighborhood is still empty, with fully-built condos and retail spaces.

Cleveland's Cuyahoga River caught fire over a dozen times

Between 1868 and 1969, the Cuyahoga River in Cleveland caught fire at least 13 times due to oil and industrial waste. The 1969 blaze garnered national attention, prompting federal action and contributing to the creation of the EPA, which ultimately led to a successful cleanup of the river.

Henry Ford once ran a failed rubber plantation in Brazil's Amazon Rainforest

In 1927, Henry Ford bought 2.5 million acres of land off the Amazon River in Brazil, with the intention of creating an American-style Ford factory to produce the rubber needed for tires. The development, known as Fordlandia, was never able to produce enough rubber, and Fordlandia was officially shut down in 1945.

Climate change skepticism and business interests politicized environmental protection

The EPA was created under a Republican administration with bipartisan support in response to overwhelming public demand during a time of visible pollution and environmental crises. Beginning with President Reagan, the agency was recast as burdensome, and environmental regulations have been gradually rolled back.

Abandoned racetracks can be found via Google Earth

With auto racing a favorite American pastime in the 1900s, tracks both small and large were built across the country. Some were local tracks used for small races, while others were super-speedways used by NASCAR.

Growing EV adoption requires battery management infrastructure

Despite rechargeable batteries' limited life cycle, companies like Spiers New Technologies have developed methods to repair, refurbish, repurpose and recycle these components to minimize environmental waste, lower demand for new critical minerals, and increase electric vehicle lifetimes.

Why are ancient ruins underground?

When cities fall into disrepair, it's often easier to flatten what you can and build on top. This is why modern archaeologists frequently discover ruins underground, revealing generational layers of cities rebuilt over time. This video explores major examples of this principle, from ancient Troy to even modern Seattle.

How house colors can indicate gentrification

Reporters from the Washington Post share an analysis that indicates gray and neutrally toned houses are signs of gentrification in a neighborhood. Visuals of different paint swatches help illustrate which colors are chosen for newly built homes in certain DC districts.

Learn about the applications of radioactivity in medical, academic, and industrial settings

Besides their use for radiometric dating by archaeologists and researchers at museums and universities, radioactive materials are used in sensors that help track ocean currents and analyze pollution, soil, and petroleum products. Radioisotope-based sensors also help measure air in ice cream and prevent spillovers when soda bottles are filled in factories.

Why Kansas is giving away cheap land

In Lincoln, Kansas, a housing renaissance is underway, driven by affordable real estate prices and a lower cost of living, in stark contrast to high-priced urban centers. Bradley Roberts, who previously lived in San Francisco, moved to Lincoln and...

Cities and parks often work to prevent graffiti

Although some call it art, many see it as an eyesore and try to prevent it through prohibitive designs, lighting, and vandal-proofed coatings that make spray paint easier to remove. This guide from the Project for Public Spaces outlines some of those strategies and more.

A 1987 garbage barge that no state would accept accidentally sparked the US recycling movement

In the 1980s, an Alabama businessman loaded 3,168 tons of mafia-controlled New York trash onto a barge. It was rejected by six states and three countries, sparking a media frenzy. This event helped convince Americans that they were running out of landfill space, giving rise to curbside recycling.

Abandoned malls prompt 'liminal' vibes of being stuck in time

Fungi have been used to restore island habitats in the central Pacific

After removing 1.5 million invasive coconut palm trees and eradicating the black rats that fed on them, as well as seabirds and crabs, conservationists working with the US Fish and Wildlife Service identified areas where fungi could be transplanted to provide nutrients to native trees. These trees serve as nesting sites for seabirds whose guano nourishes coral reefs.

A guide to crude oil and natural gas extraction, from rig site preparation to land restoration

Requirements for traffic plans, access roads, and noise barriers vary by state and local laws, but once the rig site is prepared, the rig is assembled and digs a well that is then encased in steel and cement to protect groundwater reservoirs. After drilling and testing the extraction pipe, fracking fluid is injected into the rock to create cracks where crude oil resides, allowing it to be pumped out.
