Mushrooms soak up fire debris toxics in stormwater

Stett Holbrook, NORTH BAY BOHEMIAN

The disaster of October’s wildfires didn’t stop once the flames were finally extinguished. The toxic ash left by the firestorms—incinerated plastics, hydrocarbons, solvents, pesticides, heavy metals—lay like a ticking bomb on home sites, awaiting a rain storm to wash the deadly debris into drains and creeks. Once in waterways, the lethal plume could infiltrate watersheds and imperil drinking water and aquatic life. But thanks to an unprecedented public-private partnership, protection from that environmental hazard in hard-hit areas like Coffey Park, Larkfield-Wikiup and Fountain Grove has come from an unlikely source: mushrooms.

Erik Ohlsen, a landscape architect and permaculture educator, saw that second wave of disaster coming and acted quickly to rally a diverse team of volunteers, environmental groups, landowners and public agencies to deploy cutting-edge bioremediation techniques using mushrooms and compost to absorb and neutralize the deadly runoff. He created the Fire Remediation Action Coalition on Facebook to help organize the effort and spread the word.

And word spread quickly. The project took off as another example of the volunteerism and generosity that have characterized local efforts after the fire. Sebastopol’s Gourmet Mushrooms donated thousands of pounds of substrate used to grow mushrooms. Sonoma Compost and West Marin Compost donated compost. Petaluma’s Wattle Guy provided, you guessed it, wattles—barriers and fences made from natural materials like rice straw and sticks. And groups like Russian Riverkeepers and the Clean River Alliance marshaled volunteers to make, fill and install the wattles and monitor water flow during and after the recent rains.
