Turbidity vs salinity <br /> <br /> As the EPA has permitted the Hawaii Department of Health to utilize Clostridium perfringens as <br /> a secondary bacteria indicator in an attempt to eliminate the confounding factor of sediment <br /> inputs, I also examined Clostridium densities when Emeroeoccus densities were in violation (7 <br /> efull00 ml) versus when they were not (K7 cfh/100 ml). Clostridium densities are much higher <br /> on average when E'nterococcus was above the violation threshold versus not (2.7 cfu versus 0.3 <br /> cfu, respectively. Figure 4). 'fixesc results suggest that when Enterocomus is at high densities, it <br /> is likely that Clostridium will be as well. As buth bacteria are indicators of waste water, waste <br /> water appears to be the likely source for both bacteria. <br /> 6 <br /> <br /> 5 <br /> <br /> 4 <br /> <br /> 3 <br /> <br /> <br /> y II <br /> U 9 <br /> 0 <br /> YM no <br /> 6aWacem m In vipl?Npn4 <br /> <br /> Fipur? 4.
