At least 2 soil excavations must be performed on the site, at opposite ends of the proposed disposal area. Locations of soil boring or dug pits must be shown on the location drawing. For subsurface disposal, soil evaluations must be performed to a depth of at least two feet below the proposed disposal field excavation depth. For surface disposal, the surface horizon must be evaluated. Describe each soil horizon and identify any restrictive features on this way. Indicate depths where options appear.

How to browse a Soil Boring Report: The soil investigation report is a very important piece of knowledge. It describes the soil kind, soil group, depth to bedrock, depth to seasonal wetness, similarly as the depth, color, and texture of the various soil layers. The soil investigator will perform 5 or six soil boring in the proposed septic drainfield area. The soil cluster, depth to bedrock, and depth to seasonal wetness are the foremost important factors in determining if a standard drainfield is installed. Modifications to the standard drainfield embrace a field with shallow trenches or raised trenches. Where a conventional drainfield can't be put in, a sandfilter is needed. The soil boring report is valid as long because the land described in the report has not been modified by cutting away the soil or by adding fill soil. The report only describes the highest five feet of soil.
