Work undertaken during this quarter included testing various solvents for their ability to desorb the antigenic material of sample C and D from activated carbon. Both samples were eluted successfully with 60 acetone. This is the first solvent found that desorbs any appreciable amount of either antigen from carbon. This procedure is useful for both column and batch-wise operations and was more effective for sample D than C. It has been possible to recover sample D that has been diluted approximately 110,000 with Little Miami River water. Plans should be made to test the column procedure at a field site. A column should be installed above and below the outfall of a known source of these antigens. Author
