Abstract
A reagent carrying tape is captured between the soil and the outer wall of penetrometer. As the penetrometer moves with respect to the soil, the tape is pressed against an optical window in the penetrometer. Contaminants in the soil reacting with the reagents cause an optically sensible reaction in the tape to occur which is optically detected at the optical port as the penetrometer moves with respect to the tape and the soil sample. The optically sensible reaction occurring in the tape is optically isolated from the masking effects of the soil. A method is also disclosed.
