Heavy metals contaminate underground and surface waters from illegally constructed industrial and municipal landfills. Numerous papers on the subject contain undeniable evidence, and they have determined heavy metal migration into nature by measuring concentrations in underground and surface waters near tailings ponds and landfills.

This paper provides an overview of the literature on the subject, with the goal of emphasizing the anthropogenic influence of heavy metal pollution as a critical issue, particularly in developing countries
