What should an inspector do if they observe surfacing effluent?

When an inspector observes surfacing effluent, it is a clear indicator of potential system failure. This condition suggests that wastewater is not being adequately treated and is reaching the surface of the ground, which can pose serious environmental and health risks. This could indicate issues such as a clogged drain field, an overloaded system, or even design flaws. Recognizing surfacing effluent as a sign of potential failure is crucial for determining the appropriate actions needed to address the issue and ensure compliance with regulatory standards.

The other options might lead to improper handling of the situation. Continuing with the inspection process without addressing the surfacing effluent could overlook a significant potential hazard. Immediately recommending system replacement would be premature without further evaluation and diagnosis of the specific issue causing the surfacing effluent. Documenting it for future reference only would not adequately address the immediate risks associated with the condition. Hence, considering it a sign of potential system failure is the most responsible and appropriate course of action.
