1. A method for determining a value for a water treatment parameter of a water sample implemented by a computer having a processor in communication with a non-transitory computer readable storage medium having stored instructions that, when executed by the processor, cause the computer to perform the method, comprising:
controlling an instrument, by the computer, to obtain measurements of fluorescence emission spectra of the sample including a first peak emission wavelength and a second peak emission wavelength, respectively, emitted in response to an excitation wavelength of 254 nm, the second peak emission wavelength being different from the first peak emission wavelength;
determining, using the computer, a first component value relating to the water treatment parameter associated with the first peak emission wavelength and a second component value relating to the water treatment parameter associated with the second peak emission wavelength;
calculating, by the computer, at least one coefficient, each coefficient calculated based on a correlation between a respective one of the fluorescence emission spectra peaks and a corresponding one of the components; and
calculating, using the computer, the value for the water treatment parameter based on the first and second component values and the at least one coefficient.
