Texture-by-Feel Analysis

Texture-by-Feel Analysis. Texture-by-Feel Analysis shall be performed in accordance with United States Department of Agriculture, Natural Resource Conservation Service standards: 1. The soil determination will be made based on soil borings to a depth up to 5 feet or to a depth sufficient to reach a restrictive Soil Horizon. Restrictive soil or site conditions may preclude the use of any Individual On-site Wastewater Disposal System. 2. The soil information such as texture, structure, landscape position, color and seasonal high water table depths, will determine the treatment and disposal system to be installed, constructed and approved by the Department. 3. The Soil Profile is recorded in inches on the Soil Profile Sheet by indicating the following: a. Natural Ground Surface (0 inches). b. Depth of each Soil Horizon with: i. The Soil Texture. [See Figure 4: Texture-by-Feel Analysis.] ii. The Munsell Soil Color Chart (moist soil conditions). iii. Seasonal High Water Table indicator, if applicable: (1) Seasonal High Water Table indicators may be determined by the presence of colors of chroma 2 or less (Munsell Soil Color Chart) at ≥2 percent of soil volume in mottles or matrix of a Soil Horizon. (2) Seasonal High Water Table indicator may be determined by the indication of redoximorphic features at ≥2 percent of soil volume of a Soil Horizon in accordance with methods in the Field Book for Describing and Sampling Soils, NRCS, USDA. This procedure shall take precedence over Sub-item (1) of this Section. The Field Book is hereby incorporated by reference, including any subsequent amendments and editions. (3) Another method to determine Seasonal Water Table indicators is outlined in Section 104.03. iv. Restrictive Horizon depth, if applicable. Source: Miss. Code Ann. § 41-67-3.
