  • Alkalinity Concentration of calcium carbonate (in mg/L)

  • pH Acidity

  • Calcium Amount of calcium in water

  • Chlorophyll Amount of chlorophyll in water

  • AvgMercury Average mercury level for a sample of fish (large mouth bass) from each lake

  • NumSamples Number of fish sampled at each lake

  • MinMercury Minimum mercury level in a sampled fish
