The soil does however, fall within the bounds of the CalTrans model for Normal-Acidic backfill. The use of the CalTrans model will result in larger wire sizes (W7) and/or require heavier galvanization (2 oz/ft.2). The electrochemical characteristics indicated by the test results, while creating the potential for higher corrosion rates than initially predicted do not preclude the use of the onsite material for wall backfill. A copy of the CalTrans model is enclosed for your reference. If you have any questions or require additional information, please feel free to contact me at your earliest convenience.
