What describes the particle size of Soil Type 6?

Soil Type 6 is characterized by coarse gravel, which consists of larger particles compared to other soil types. Coarse gravel typically includes particles that are larger than 2 mm in diameter and can range from roughly 2 mm to 64 mm. This larger particle size affects the soil's drainage properties, demonstrating high permeability and relatively low water retention.

Coarse gravel also provides a different structural support for septic systems compared to finer soils. The size of the particles allows for good aeration and can help prevent clogging in septic systems, making it a suitable choice for certain applications. Understanding particle size classification helps in determining the suitability of a soil type for various uses, including construction and waste management systems, such as septic tanks.
