LTAR refers to what?

LTAR refers to what?

• A. The Rate at Which Soil Drains Away Rainfall
• B. The Rate of Evaporation from Soil
• C. The Rate of Groundwater Recharge
• D. The Rate at Which Soil Can Accept Septic Effluent Over the Long Term

Answer: (D)

LTAR is about how much septic effluent the soil can accept over time. It describes the long-term capacity of a soil absorption system to infiltrate and treat wastewater without causing surface ponding or contaminating groundwater. This focus on the sustained loading of effluent distinguishes LTAR from general soil drainage, evaporation, or groundwater recharge, which are different hydrological processes. In practice, LTAR helps determine whether the soil and site can safely handle the anticipated septic system discharge over the long term, guiding how large the infiltration area should be.
