Equipment for FieldFluorometric Method• Fluorometer attached to a sonde• Technician• The sonde will read out the concentration• This method is not reliable when algae physically floats in mats.
Summary• <strong>Chlorophyll</strong> A levels• Give us a snapshot of the algal biomass in the water• This correlates with the nutrient load• <strong>Chlorophyll</strong> A is only half of the story• The types of algae can tell us if our system is potentiallytoxic• If there is too much P or N• Not all strains of cyanobacteria are toxic• With minimal training, anyone that canmicroscopically analyze a sludge sample can analyzealgae in a water sample.
