What is one of the primary risks of not conducting a site evaluation before septic system installation?

Not conducting a site evaluation before the installation of a septic system significantly increases the risk of potential groundwater contamination. A site evaluation assesses the soil's composition, drainage capacity, and topography, which are crucial for ensuring that the septic system functions correctly and safely. If a proper evaluation is skipped, there may be inadequate information about how effluent from the septic system will be treated and absorbed by the soil.

Without this assessment, there is a considerable chance that the septic system could fail to operate effectively, leading to the improper disposal of waste. This can cause contaminants to leach into the groundwater, posing serious health risks to both the environment and any nearby water sources used for drinking or irrigation. Protecting groundwater quality is essential, as it supports not only local ecosystems but also human health, making this risk a primary concern when planning for septic system installation.
