Which activity is commonly associated with sending soap and other pollutants into storm drains?

• A. Car Washing in Driveway
• B. Washing Vehicles at a Commercial Car Wash
• C. Power Washing Buildings
• D. Boat Cleaning at a Marina

Answer: (A)

The main idea is how polluted water from everyday activities can flow untreated into storm drains. Washing a car in a driveway often uses soap and dirty water that runs off pavement and directly into street gutters, eventually reaching storm drains. Those drains usually discharge straight into nearby rivers or lakes without treatment, so detergents, oils, and metals hitch a ride to the water body. Washing vehicles at a commercial car wash is designed so the wash water is collected and treated before entering the sewer system, reducing the chance it reaches storm drains. Power washing buildings and boat cleaning at a marina can also involve runoff, but their systems are typically more controlled or routed away from storm drains, making direct, untreated discharge less common.
