Bioremediation for Fire Affected Sonoma County

West Marin Compost is constructing free wattles (for fire relief), which have been inoculated with mycelium to provide bioremediation for the fire affected lands in Sonoma County.  The wattles, long 8″ diameter socks that are filled with straw, compost and mulch, will be placed in areas where the risk of run-off of water contaminated with oil, gas, pesticides, leaded paints, chemicals, etc. is a risk to the environment, particularly our water resources.

The Lafranchi Family have donated all of the straw bales from the Nicasio Pumpkin Patch.  Chip StrawGourmet Mushroom, Inc. is providing the fungi.  Clean River Alliance transports the fungi substrate to our facility. Many volunteers are chipping in providing labor to put the whole package together with West Marin Compost providing compost, mulch, wattle socks, equipment, labor, coordination and transportation.

Volunteering is on hold.  Stay tuned

 

How does it work?  The wattles will provide erosion control by slowing down the water, allowing sediment to settle out and reducing the energy of the water.  Compost in the wattles has the ability to immobilize heavy metals, thereby removing them from the environment.  The microbes in the wattles see hydrocarbons (gas, oil, many pesticides) as a food source and will break them down.  The added fungi are vey good in filtering out heavy metals, chemicals and hydrocarbons.  We are building bioreactors, where nature can do its work to clean up.

What about noxious weeds?

Does West Marin Compost accept noxious weeds, and what happens to weeds in the composting process?

WMC does accept almost all “weeds.”  Except for Tim.

In all seriousness, most weeds and weed seeds are destroyed by the high

temperatures of the thermophilic composting process.  One notable exception is

the seeds of common garden morning glory (Convolvulus arvensis), which have

 been shown to survive temperatures of up to 180 F.  Consequently, we do not

accept this material at the drop off site.   

Most other plant material is accepted.

How is the compost made?

Dairy manure separator solids are combined with approximately equal volumes of green and equestrian materials, formed into windrows on the composting pad and watered as needed. Any runoff from the compost area flows to the dairy’s liquid waste storage ponds. Windrows are managed in accordance with CAL Recycle and USDA National Organic Program (NOP) guidelines to reduce pathogens and weed viability to negligible levels.  A mechanical screen is used to separate coarse from fine material at the end of the process.

How is compost better than liquid manure?

Because finished compost is a dry material (typically less than 50% moisture at maturity, it is less costly to spread than wet manure (typically 75-95% water). Finished compost is odorless and the nutrients it contains are much less mobile under rainfall conditions than manure.  In fact, compost is often used as an erosion control material to help prevent soil movement on disturbed sites. Properly composted material does not contain viable weed seeds, which liquid manure often does, so spreading compost does not spread thistles or other weeds.
