When assessing a site for a septic system, the depth at which soil shows wetness tells you how much of the soil profile remains usable for effluent disposal. If wetness is found at a depth of 36 to 48 inches, there is still a decent unsaturated zone above it, but the presence of moisture at that depth indicates potential seasonal or perched groundwater that could affect drainage and performance. That combination is not ideal, yet it isn’t a disqualifier, so the site is classified as provisionally suitable. It signals that the site can be used for a system, but with restrictions or design adjustments and possibly additional testing to ensure that the wetness conditions stay within that range and won’t impair functioning.
