What is one negative consequence of a failing septic system?

A failing septic system can lead to environmental contamination, which is a significant concern. When a septic system malfunctions, it can cause untreated sewage to leak into the surrounding soil and groundwater. This contamination can harm ecosystems, pollute drinking water sources, and pose health risks to humans and animals. Contaminated water can lead to the spread of diseases and negatively affect local flora and fauna.

Improved water quality, an increase in property value, and enhanced drainage are not plausible outcomes of a failing septic system. In fact, these would be indicators of a properly functioning system or related improvements. Thus, environmental contamination is the clear and direct negative consequence associated with septic system failures.
