New York Times: Superfund meet Super Plants
An hour’s drive south of San Francisco, a stand of several hundred poplars grows in a Y-shape — a rather unusual sight wedged between two baseball fields. The trees were planted in 2013 to suck carcinogens out of a 1,500-acre Superfund site contaminated by...
NASA Field Tests Microbes that Help Trees Clean Up Pollution
NASA explores outer space, but it’s also owner and steward of hundreds of square miles of planet Earth. The scientists and engineers at the space agency’s field centers have tried various methods to preserve the land they work on, and several of these have found use around the rest of the planet.
Arbor Day Foundation and Intrinsyx Environmental offer natural solution to clean up industrial contamination in cities and towns
Intrinsyx Environmental is excited to announce a new partnership with The Arbor Day Foundation. Founded in 1972, the Arbor Day Foundation has grown to become the largest nonprofit membership organization dedicated to planting trees, with more than one million members, supporters, and valued partners. Since 1972, more than 400 million Arbor Day Foundation trees have been planted in neighborhoods, communities, cities, and forests throughout the world...
Intrinsyx Environmental and The Arbor Day Foundation's new partnership
In 1980, a federal law identified the most hazardous sites around the United States, those that contained toxic contaminants in urgent need of cleanup. These “Superfund sites,” named for the initial funding allotted to the cleanups, are chiefly old industrial sites...

Phytoremediation is the use of plants to extract a wide range of heavy metals and organic pollutants from the soil. Phytoremediation removes metals and volatile organic compounds from soils through strategic installation of plants. These plants uptake pollutants into their biomass to store or degrade them. 3 Chlorinated compounds as environmental contaminants occur in many forms, from solvents to industrial chemicals to pesticides. Many of our phytoremediation installation sites contain shallow...
Trees with a probiotic boost clean up a carcinogen
Panting poplar trees that harbor a secret weapon—pollutant-busting microbes—could help clean up sites contaminated with the carcinogen trichloroethylene, a new study shows. In the first field trial of this approach at a Superfund hazardous waste site, poplar trees boosted by bacteria within their tissues brought groundwater concentrations of TCE to below the maximum contaminant level for drinking water set by the U.S. Environmental Protection Agency.
Arbor Day Foundation and Intrinsyx Environmental offer natural solution to clean up industrial contamination in cities and towns
Scientists using a microbe that occurs naturally in eastern cottonwood trees have boosted the ability of two other plants – willow and lawn grass – to withstand the withering effects of the nasty industrial pollutant phenanthrene and take up 25 to 40 percent more of the pollutant than untreated plants.
Probiotics help poplar trees clean up Superfund sites
Trees have the ability to capture and remove pollutants from the soil and degrade them through natural processes in the plant. It’s a feat of nature companies have used to help clean up polluted sites, though only in small-scale projects.
Now, a probiotic bacteria for trees can boost the speed and effectiveness of this natural cycle, providing a microbial partner to help protect trees from the toxic effects of the pollutants and break down the toxic
