Can evidence of groundwater be present within 2 feet of excavation?

Groundwater can indeed influence the design and installation of on-site sewage facilities; however, the presence of groundwater within 2 feet of excavation is typically not acceptable for several reasons. One important consideration is that the effluent from the septic system needs adequate treatment before it reaches the groundwater. If groundwater is present too close to the installation site, it can lead to premature failure of the system due to inadequate filtration and potential contamination of the groundwater.

Keeping excavation free of groundwater helps ensure that the soil has the capacity to adequately treat the effluent through natural processes. It also allows for proper installation and functioning of the system components, such as the drain field, reducing the risk of surface water pollution and maintaining public health standards.

This standard practice emphasizes the importance of site evaluation and preparation prior to system installation to ensure compliance with health and safety regulations concerning wastewater management.
