In the context of an OSSF, what is typically assessed during a site evaluation?

The assessment of soil conditions and proximity to water sources during a site evaluation for an On-Site Sewage Facility (OSSF) is crucial for ensuring the effective functioning and safety of the system. Soil conditions are examined to determine the type, percolation rate, and overall suitability for the installation of a sewage system. For instance, different soil types have varying capacities to treat effluent, which affects how well the system can function without causing environmental contamination.

Proximity to water sources such as rivers, lakes, or groundwater is also assessed to prevent contamination. By ensuring a safe distance between the OSSF and these water sources, the evaluation helps in protecting public health and the environment from the potential discharge of pathogens or pollutants. Overall, these factors play a foundational role in determining whether a site is appropriate for an OSSF and how it should be designed and constructed.
