| Description: | Special Report Abstract: The use of carbon and nitrogen stable isotope measurements from TNT was examined as a possible tool for monitoring the natural attenuation of TNT. Incubation studies of spiked soil samples were conducted. The concentration of TNT and the del (δ) values for 13-C and 15-N of the soil and of TNT were measured with time. Results indicated that no measureable changes in the δ13-C or δ15-N value of the soil or δ13-C values for TNT could be detected as the concentration of TNT decreased. Measureable changes in the δ15-N value of TNT with changing TNT concentration suggested a possible monitoring route. Field studies using both soil and groundwater samples support the laboratory finding that changes in the δ15-N for TNT extracted from groundwater could be detected in samples collected at different points along transects at the Louisiana Army Ammunition Plant and that no measurable change in the δ13-C values for soil or TNT could be seen. |
