Name one environmental concern associated with septic systems.

Contamination of groundwater is a significant environmental concern associated with septic systems. When septic systems are not properly designed, installed, or maintained, they can leach harmful bacteria, pathogens, and nutrients into the groundwater. This contamination can occur if the septic tank or leach field fails, if there are cracks in the tank or lines, or if the system is overloaded with wastewater. Groundwater is a critical source of drinking water for many communities, and contamination can pose serious health risks, lead to the degradation of water quality, and impact ecosystems that rely on clean water sources. Proper maintenance and adherence to regulations are vital to prevent such contamination and protect both public health and the environment.
