What does polluting mean?
Polluting means making something dirty, contaminated, or harmful to people, wildlife, or the environment. The word commonly appears in discussions of air pollution, water contamination, waste disposal, industrial activity, and the degradation of natural habitats. For example, a factory may be described as polluting a river when its discharges introduce harmful substances into the water. As a participial adjective, “polluting” usually modifies a noun such as “emissions,” “industries,” or “practices” and carries a strongly negative evaluative meaning. The term is not restricted to visible or chemical waste: noise, light, radioactive material, and other forms of contamination may also be described as polluting. Distinguishing “polluting” from “polluted” is useful in formal writing, since the former identifies the harmful action or source, while the latter describes the resulting contaminated condition. Together, the two forms make it possible to discuss both responsibility for environmental damage and its consequences.
To make a place, substance, or environment dirty, contaminated, or harmful.
"Runoff from farms is polluting nearby streams."
The form is both a present participle and a gerund. In a gerund construction, it normally takes “of,” as in “the polluting of public waterways.”
Causing pollution or contamination; characterized by harmful environmental effects.
"The company was ordered to reduce its polluting emissions."
This is a participial adjective and is normally used before a noun.
A single polluted stream can carry harmful contamination far beyond the place where the pollution began.

Where does polluting come from?
Polluting is the present participle of pollute, a word inherited into Middle English from Old French. Old French polluer came from Latin polluere, meaning “to defile” or “to soil,” which was derived from polmus, an ancient Latin word for mud. English later formed related words including pollution, polluter, and pollutant from this same root.
How polluting is actually used
When used attributively, as in “polluting practices,” the word normally has a negative, often judicial or environmental, connotation. The related adjective “polluted” more often describes the affected substance or place.
