Which LTAR range is associated with Soil Group II (Sandy Loam/Loam)?

Explanation:
Long-term absorption rate (LTAR) is the soil’s sustained ability to infiltrate septic effluent, stated in gallons per day per square foot. For Soil Group II, which includes Sandy Loam/Loam textures, the infiltration capacity is moderate. That places its LTAR in the mid-range, specifically about 0.6 to 0.8 gpd/ft^2. So the LTAR range associated with this soil group is 0.8 to 0.6 gpd/ft^2. In design terms, a higher LTAR means less area is needed to handle a given daily flow, while a lower LTAR means more area is required. The other ranges correspond to soils with different infiltration rates—faster, slower, or much slower infiltration—so they don’t match the moderate capacity of Sandy Loam/Loam.
