1. A system configured for monitoring water from a water facility, the system comprising:
a sampling unit comprising a water sample, sampled from the water facility;
at least two light sources, each configured to emit light of a different wavelength (WL) peak, for illuminating the water sample in the sampling unit;
at least one spectral detector, configured and positioned to detect spectral characteristics of light exiting from the sampling unit, when illuminated by each of the at least two light sources, and output updated detector data indicative of updated spectral characteristics of light detected thereby; and
a processing unit configured to receive and analyze:
(i) updated detector data from the at least one spectral detector associated at least with updated spectral measurement of the water sample obtained when the water sample therein was illuminated by the at least two light sources, and
(ii) assumed WL peaks of each of the at least two light sources, and perform spectral analysis of the received updated detector data, using an analysis model, to determine, one or more updated characteristics of the sampled water,
wherein the processing unit is further configured to determine spectral shifts between assumed WL peaks of the at least two light sources and measured WL peaks of the at least two light sources, measured by the at least one spectral detector, for adjusting spectral analysis of the updated detector data arriving from the at least one spectral detector, used for determination of one or more characteristics of the water sample, based on determined spectral shifts.
