• summary of the clean water act, environmental protection agency

what is the best way to use the clean water act to address the issue of dirty water and diseases that plague a small community?
o to report the number of cases of people who have cholera symptoms
o to provide health guidelines about effects from waterborne diseases
o to enforce standards that focus on chemical discharge into bodies of water
o to carry out research that investigates how dirty water affects human health

Explanation:

The Clean Water Act (CWA) is about regulating pollutant discharges. Reporting cholera cases (first option) is more about disease tracking. Providing health guidelines (second option) and researching water - health effects (fourth option) are not the main focus of the CWA as per its summary. The CWA's main structure is regulating discharges, so enforcing standards on chemical discharge (third option) aligns with its purpose.

Answer:

to enforce standards that focus on chemical discharge into bodies of water
