What is the minimum land area requirement for public water supply with Soil Type 6?

The minimum land area requirement for a public water supply using Soil Type 6 is established at 18,000 square feet. This criterion is based on the specific characteristics of Soil Type 6, which typically has limitations regarding its ability to effectively filter and manage wastewater. These limitations necessitate a larger area to ensure adequate treatment and absorption of effluents.

For public water supplies, having sufficient land area is crucial not only for the water source itself but also for the surrounding infrastructure and environmental protection. This helps mitigate contamination risks and supports sustainable management practices. The other provided options suggest larger land areas, which may be relevant for other soil types or different conditions, but they exceed the specific requirement set for Soil Type 6, which has been determined through regulatory standards and environmental assessments. Thus, 18,000 square feet is the correct minimum area necessary for effective and safe public water supply management in this context.
