Are current regulations for an on-site disposal system aimed at ensuring all wastewater is absorbed into the soil?

The current regulations for on-site disposal systems, commonly referred to as on-site sewage facilities (OSSFs), are designed to ensure that wastewater is treated effectively before it is released into the environment. While absorption into the soil is an important aspect of many OSSF designs, regulations do not solely focus on this one method. Instead, they encompass a variety of treatment methods that can include mechanical, biological, and chemical processes, depending on site-specific conditions and local requirements.

In many cases, the effectiveness of the system is evaluated based on its ability to protect public health and the environment, which might require that wastewater undergo certain treatment processes before it can safely contribute to soil or groundwater. This highlights a broader goal than just absorption—it includes ensuring that any potential risks associated with wastewater are managed appropriately.

Regulatory frameworks take into account different environmental factors such as soil type, drainage capabilities, and proximity to water sources, which can influence the appropriateness of soil absorption in a given location. Therefore, while soil absorption is a goal for many systems, it is not the only regulatory focus, making the statement that regulations aim solely at ensuring absorption into the soil false.
