Is wastewater a metal?
Untreated wastewater, especially from industrial sources, is often contaminated with various metals. In small amounts, these metals are not harmful, but they are usually heavily concentrated in wastewater. If the water is not properly treated, then the metals will be deposited in the soil and consumed by plants. Many farms and croplands are irrigated primarily by treated wastewater. Over time, these crops will take up larger concentrations of metals, which ultimately contaminates the food supply. Worse, this contamination is extremely difficult to detect.
