The concept of entropy as a state function is employed in this paper within a radiation system designed to address the role of atomic disturbance in determining the levels of physical permeability changes in the studied states, comparing the results with those of a clean phase. This investigation begins with samples prepared for characterization tests using a unique technique for electromagnetic irradiation. The samples included: (1) a rainwater sample carefully collected during the first week of February 2024, serving as a high-quality natural reference in its aqueous phase; (2) a sample from a 42-meter-deep drinking water well (GW) in Ghout al-Dees, west of Tripoli, Libya; and (3) a bottled water sample (AA-WS3) commonly available in the Libyan market. The test results focused on the values of the physical property (τC), identified from the relationship between the entropy operator and time, as a physical fingerprint that accurately detects disturbed material permeability. The study concludes with a section linking the properties of the natural reference phase to the fingerprint characteristics of the studied samples, providing an approach to assess the quality of the tested water samples against the ideal chemophysical quality of rainwater. This led to findings that (1) the groundwater quality (QAA-WS2) was 76.92%, and (2) the quality of bottled water available in the Libyan market (QAA-WS3) was 74.57%, highlighting the role of the polymer composition in plastic container packaging as an additional factor, alongside the structures enclosing water sources, as in the case of the groundwater well exposed to contamination...............
