Question

how can drinking water become contaminated with wastewater? leaks from septic tanks into groundwater the release of treated water from industries using treated water from city water storage using water from wells dug on private land

Explanation:

To determine how drinking water gets contaminated with wastewater, we analyze each option:

• "Leaks from septic tanks into groundwater": Septic tanks hold wastewater, and if they leak, this wastewater can enter groundwater (a source of drinking water), causing contamination.
• "The release of treated water from industries": Treated water from industries is typically not wastewater (it's treated to be safe) and is released in a controlled, non - contaminating way for drinking water sources.
• "Using treated water from city water storage": City water storage's treated water is for drinking, so this doesn't contaminate drinking water with wastewater.
• "Using water from wells dug on private land": Well water, if properly maintained, is a clean drinking water source and doesn't involve wastewater contamination.

So the correct option is the one about septic tank leaks.

Answer:

Leaks from septic tanks into groundwater
