Soil Analytical Chemical Test Results Soil samples for analytical testing were retrieved from the depths referenced below, in Table 2. The attached Soil Analysis Report illustrates the test results. Analyzed constituents relating to nitrate loading include the organic matter content of the soil,pH, Cation Exchange Capacity (CEC), and the nitrate-nitrogen content. The organic matter is low throughout the shallow soil profile, indicating a low contribution of nitrogen release. The pH is alkaline at each tested depth. This alkalinity can inhibit nitrification and promote denitrification. The CEC indicates the soil potential to retain ammonium molecules that are in the septic system effluent. Therefore, the CEC has a high potential to inhibit nitrification, and is high in the soil profile. Of significance are the nitrate-nitrogen concentrations at each depth, revealing a low concentrations throughout the soil profile down to 8.75 ft.
