Article 1
Evaluation Criteria for Subsurface Soil Absorption Systems

Soil evaluation for a subsurface soil absorption system shall follow a systematic approach including consideration of physiographic province, topography, available area, degree of slope, and soil profile (thickness of each horizon, color, permeability, and texture). The evaluation is intended to document sufficient information to conclude whether or not the site can accommodate an onsite sewage treatment and dispersal system listed in Part IV (12VAC5-610-591 et seq.) of this chapter. The topography, available area, seasonal water table, drinking water supplies, bodies of water, shellfish growing areas, soil horizon, depth, rate of absorption, or combination of any of the above shall be considered in such evaluation. A percolation test may be required as a prerequisite to the issuance of a permit. When the district or local health department questions the estimated percolation rate, the district or local health department may require a percolation test. Percolation tests shall be analyzed as only one of many criteria in determining soil suitability for absorption of treated sewage.
