This slide presentation outlines a study with the objectives of: evaluating the potential of naturally present and addedchemicals as fluencemeters;focusing on germicidal fluences (~ 100 - 2000 J m<sup>-2</sup>);testing both low- and medium-pressure Hg lamps; and,examining the effect of water qualitye.g., pH, TOC. Experimental procedures included:low- and medium pressure Hg lamps for Fe<sup>3+</sup>and BA/H<sub>2</sub>O<sub>2</sub>, medium pressure for NO<sub>3</sub>-;collimated beam experiments, radiometricfluence determination;shallow solution depth (< 1 cm);NO<sub>2</sub>- and Fe<sup>2+</sup> analyzed by colorimetry; and,Hydroxy-BA analyzed by reversed phase HPLC. Includes figures.
