    Word(s) Definition Image Caption Link Source
    Alkalinity The ability of a solution to buffer against changes in pH        
    Coliform The general group of bacteria that can be used as an indicator to determine if pathogenic microorganisms are also present        
    Eutrophication An increase in nutrients in a waterbody that promotes excessive algae growth to the point where oxygen levels in the waterbody are depleted and unable to support other aquatic life        
    Imhoff cone Inverted cone-shaped laboratory equipment used to determine the amount of settleable solids        
    Metazoa A multi-celled microorganism        
    Nonpoint source Sources of pollution that cover a wide area of land. A source that is difficult to identify as a single source of pollution into a water body        
    Pathogen A microorganism found in water that can cause disease to a person        
    pH A measure of the acidity or basicity of a solution from a scale of 0 to 14. Zero being the most acidic and 14 being the most basic        
    Point source A single identifiable source where treated wastewater is discharged into a water body        
    Protozoa A single-celled microorganism        
    Settleable solids Solids that will settle to the bottom on an Imhoff cone        
    Total dissolved solids Solids in wastewater that will pass through a filter and are molecularly combined with the water molecules. (TDS)        
    Total suspended solids Solids in wastewater than can be trapped by a filter and measured in mg/L. (TSS)        
    Waste Load Allocation The total amount of a certain pollutant that can be discharged by a point source and still meet the TMDL of a water body
