All Clear Septic and Wastewater Services All Clear Septic and Wastewater Services often has calls relating not just to septic tanks but also leach fields or drain fields which are a necessary part of your septic system.  A leach field is the area through which effluent from the septic tank is dispersed into the soil to be filtered.   In the leach field, the effluent moves through the pipes and seeps into the surrounding soil.  The soil filters out suspended solids and organic matter.  Bacteria in the soil then decomposes harmful microorganisms and other organic components.  Clay particles trap viruses which eventually die.  Treated effluent continues downward as it percolates through the layers of soil.  Leach fields are not always built the same way or the same size.  Things like soil types, topography, trees, and nearby wells can all dictate the size and design specifics of a leach field.  Failure of a leach field is often caused by plugging caused by a failed septic tank.  Particles of nondecomposed septic material escape the septic tank outlet baffle and decrease the permeability of the leach field soil.  Over time the effluent water, often containing dangerous bacteria, may seek relief by bubbling up to the surface since it no longer can be absorbed properly downward into the ground.  Offensive odors usually accompany this event.  If you have puddling on your leach field or very green and lush growth over it, these are indications that you may have a problem that should be looked at.  All Clear Septic and Wastewater Services has experience with septic system repairs including leach field repairs.  We have septic repair appointments today in Hingham, Scituate, Marshfield, East Bridgewater, Plymouth, Carver, and Middleboro, MA.  If you need to make an appointment or if you have any questions please do contact our office at 508-763-4431 or visit
