Which of the following is a common sign of septic system overflow?

Foul odors and pooling water are indicative signs of septic system overflow. When a septic system is functioning properly, wastewater is effectively treated and absorbed into the soil. However, if the system becomes overloaded or if there are blockages, it can lead to excess effluent surfacing in the yard. This effluent can produce unpleasant odors, which are a clear sign of malfunction. The presence of pooling or standing water in areas where it should not typically be present further confirms that the system is struggling to handle the wastewater, leading to overflow.

In contrast, healthy grass growth typically suggests that the septic system is functioning properly, as the grass receives nutrients from the treated effluent. Similarly, dry soil around the drain field indicates that the system is functioning effectively, as it should be allowing for proper absorption of water. Barriers preventing water from draining can obstruct flow but are not a common symptom of overflow; they may contribute to other issues instead. Understanding these signs helps in the timely identification and remediation of septic system problems.
