What should be avoided when considering the installation of an OSSF?

Placing the system near a water well or surface water body is critical to avoid due to the potential for contamination of drinking water sources and ecological harm. On-site sewage facilities (OSSFs) rely on the proper treatment and disposal of wastewater. When these systems are too close to a water well, there is a risk that pathogens or pollutants from the sewage system could migrate into the well, jeopardizing public health. Additionally, proximity to surface water bodies can lead to untreated effluent entering these waters, causing pollution and harming aquatic environments. The guidelines for OSSF installations emphasize maintaining appropriate distances to ensure that groundwater and surface water are protected from contamination.

Other choices present considerations that may not directly impact health or environmental safety in the same crucial way. For instance, while installing an OSSF in shaded areas might not be optimal for optimal evaporation rates, it does not inherently pose the same level of risk as proximity to water sources. High-quality materials are essential for longevity and efficiency, and having multiple systems is manageable under certain conditions, provided they meet regulatory standards. However, the crucial element is ensuring that the installation location minimizes contamination risks to vital water sources.
