520 ▼a Excessive amounts of chemicals and ions flowing into water sources, which are mainly due to efflux from agricultural lands, cause serious environmental and human-health related concerns. The lack of affordable and real-time monitoring systems fo
520 ▼a In this work, the measured dielectric spectra were fitted with a Debye model using a non-linear, weighted, least-squares analysis. Uncertainties due to random and systematic errors, that contribute to the measured dielectric spectra and become c
520 ▼a Next, the fitting parameters for the Debye model, which include static permittivity, relaxation time, and specific conductivity, have been extracted as potential indicators of ion concentration and type. A method of judiciously exploiting these
520 ▼a In addition, for separate ionic aqueous solutions of NaCl, NaNO 3, and Na2SO4, concentration- and temperature-dependent parametric models of static permittivity, relaxation time, and specific conductivity that account for physical chemistry and
