A biomat is a layer of bacteria that forms in the soil surrounding and underneath effluent dispersal field trenches where wastewater is released.  This biomat layer is vital for processing the fine biological solids and contaminants found in effluent.  Without it, a disposal area cannot adequately treat effluent. Inadequately-treated effluent discharged into the ground poses the risk of polluting nearby bodies of water.
