The study evaluates surface water quality and health risks in Mohammedia Prefecture, Morocco, analyzing physicochemical parameters, heavy metals, and associated risks from 22 water samples. Results highlight high pollution levels at certain sites (e.g., S3, S4, S5) due to anthropogenic activities, with lead and ammonia as key contributors. While non-carcinogenic health risks were minimal, carcinogenic risks at some locations exceeded acceptable limits. Could the authors clarify the methodology used for spatial interpolation of heavy metals in Figures 2 and 3, and why no additional heavy metals were analyzed given the high pollution indices?
