Soil Type 7 is considered suitable for treatment or dispersal?

Soil Type 7 is categorized as unsuitable for treatment or dispersal of septic effluent due to its poor drainage and high likelihood of waterlogging. This classification typically includes soils that have a high clay content or are otherwise compacted, leading to ineffective filtration and potential surface runoff of contaminants.

Effective soil types for septic treatment generally exhibit good drainage characteristics, allowing for the proper absorption and treatment of effluent. When soil cannot effectively perform these functions, it increases the risk of environmental contamination, making it critical to identify and understand soil classifications when designing septic systems. Thus, the statement regarding Soil Type 7's suitability is considered false.
