Optical emission spectroscopy techniques have been adopted for the measurements of plasma parameters of arcs immersed into water spoiled by waste aqueous solution for the water decontamination. Such plasmas are extremely unstable and inhomogeneous, so instead of common OES techniques based on evaluation of the plasma emission coefficients, which here do not give reliable results, a modified approach has been applied relying upon relative intensity of lines in the plasma total emission spectra and some general data on the plasma behaviour. The approach has been tested at diagnostics of argon-water plasma produced by a non-transferred arc. The measurement results give a rather realistic picture of plasma parameters and spatial distributions of active species in the plasma jet with an admixture of water.
