Treating Stormwater with Mushrooms
Mycoremediation, or the use of fungi to clean water and soil, could be joining the many tools for treating stormwater someday. Although the idea has been floating around for years, mycoremediation has yet to take off. This is due, in part, to the difficulty; the correct fungus species must be matched to the right pollutant. Most of the problem, however, is from a lack of empirical data evidence that it works.
The technique might just be gaining the evidence it needs, depending on the outcomes of two projects in Portland, Oregon. The first is a 90-day trial using mushrooms to treat the motor fuel found in street-cleaning wastewater. The second is a project to treat urban stormwater at a rock quarry and construction landfill turned Zen Center.
