Best practice

When discussing the "level of contamination", be specific about the type of contaminant and the units of measurement (e.g., parts per million, micrograms per liter) to provide clarity and context.

Common error

Avoid using "level of contamination" without specifying the contaminant. Saying "the level of contamination is high" is less informative than stating "the level of lead contamination is 500 ppm".
