Why does a leach field fail?
JSA: The main reason for failure of a leach field is plugging caused by a failed septic tank. Particles of non-decomposed septic material escape the septic tank outlet baffle and decrease the porous nature of the leach field earth. Over time the effluent water may seek relief by bubbling up to the surface since it no longer can be absorbed properly downward into the ground. Offensive odors and dangerous bacteria in the surface water can be identified. Solving the problem of the failed septic tank is the first way to correct this problem. Extending the leach field without addressing the septic tanks problem will only result in extending the problem which will eventually happen again. The best way find the extent of the failure is to ask a trained professional.
