As requested, we have sampled the surface soil on the subject lot to determine the soluble sulfate
content as it relates to selecting appropriate concrete mix designs. Testing indicates that the site
soil is generally considered non -corrosive with respect to concrete. The testing indicated a
soluble sulfate content of 350. ppm (0.035 percent) that corresponds with the "negligible"
exposure category in accordance with Table 3 of ACI 318-08 Chapter 9. In accordance with ACI
318-08, special sulfate related concrete mix designs are not required.
If you have questions regarding this letter, please contact the undersigned.
