Algal Growth with Nutrient LimitationCompared to Light-Limiting Conditions in Ozark Streams
Andrea LudwigMarty Matlock, PhD, PE, CSEBrian Haggard, PhDBob Morgan, PE
EPA use attainability study
Research Goals
Identify a nutrient, periphytic chlorophyll-a relationship in Ozark streamsInvestigate circumstances of light-limitation to native algaePredict response of algal growth to differentiating canopy covers in the presence of variable nutrients
MethodologyMatlock periphytometers deployed at all sites
Chlorophyll-a used as indicator of abundance of algae
• Chlorophyll-a analysis done using trichromatic methods
Grab samples collected at each site and analyzed for nutrient concentrations
Light meters attached to Matlock periphytometers at selected sitesSite Selection
Coupled sites according to locations of WWTPs
