Methods for detecting the concentration of one or more target organisms in a water sample. The methods involve adding a tagged reagent to a water sample, wherein the tagged reagent is water soluble; and determining a concentration of at least one bacteria in the water sample based on an intensity of an emission emitted from the water sample in response to exposure to light having a known wavelength. An apparatus including a reaction chamber; a reversible pump, a reagent source comprising a fluorophore-tagged reagent, a light source, an optical detector disposed to detect fluorescence emitted from the reaction chamber in response to light emitted from the light source; a processor configured to communicate with the reversible pump, the reagent source, the light source, and the optical detector, the processor being configured to determine the concentration of one or more target organisms in a water sample, and optionally transmit the resulting data to a remote location.
