Supplemental Information
Concentrations of chemical constituents in water are given either in milligrams per liter (mg/L) or micrograms per liter (µg/L)
Frequency is given in hertz (Hz), equivalent to cycles per second.
Conductivity is given in siemens per meter (S/m).
Light-emitting diode (LED) wavelength is given in nanometers (nm; 1/1,000,000,000 meter).
