Systems and methods for measuring properties of water at site

A method for measuring properties of water at site, the method comprising:

• emitting a broadband source signal comprising a particular bandwidth for use in measuring a range of particular properties of water;
• splitting the source signal into a measurement signal, and a corresponding reference signal;
• communicating the measurement signal through water;
• receiving both the measurement signal, having been communicated through water, and the reference signal, and separating the measurement signal and reference signal into common component wavelengths, the common component wavelengths being associated with expected properties of water;
• and
• using respective ones of the component wavelengths of the measurement signal together with those of the reference signal to determine one or more particular properties of measured water.

A system for measuring properties of water at site, the system comprising:

• a light source configured to emit a broadband source signal comprising a particular bandwidth for use in measuring a range of particular properties of water;
• a sensor unit configured to receive via a communication fiber, from the light source, a measurement signal and communicate the measurement signal through water at the sensor unit, wherein the sensor unit is configured to reflect the measurement signal back across water for receipt and further transmission using the communication fiber;
• and
• a spectrometer configured to receive a measurement signal from the sensor unit, and to separate that measurement signal into component wavelengths, the component wavelengths being associated with expected properties of water;
• wherein the system is further configured to use the component wavelengths of the measurement signal to determine one or more particular properties of measured water.
