Mon-visible pollutant monitoring is triggered by the potential for non-visible pollutants to be discharged from any project site.

Mon-visible pollutant monitoring is triggered by the potential for non-visible pollutants to be discharged from any project site.

• A. True
• B. False
• C. Only during rainfall
• D. Only for large sites

Answer: (A)

Non-visible pollutant monitoring focuses on substances you can’t see in the runoff, so the need to monitor is driven by the potential for those contaminants to be discharged from the site. It isn’t limited to rainfall events or to large sites; if there’s any potential for non-visible pollutants to enter the stormwater, monitoring is triggered. This is why the statement is true: the monitoring is tied to the potential for non-visible pollutants to be discharged from any project site, not dependent on rainfall or site size.
