Read the following and answer the question below the passage...
The Clean Water Act (CWA), enacted in 1972, is a key U.S. environmental law. Administered by the EPA, it regulates water quality by establishing standards, implementing the National Pollutant Discharge Elimination System (NPDES) for point sources, promoting Best Available Technology, controlling non-point source pollution, protecting wetlands, and enforcing penalties. The CWA aims to ensure clean water for various uses, prevent pollution, and preserve aquatic ecosystems.

Answer 1

Here are the answers to your questions:

1. Benefits of aquaponics systems compared to conventional farming:

   • Productivity per square foot
   • 5 total water usage

2. Support for the idea that aquaponics helps reduce the impact of human activities on the environment:

   • Reuse of fish waste reduces the use of fertilizers.

3. What occurred because of Flint's water crisis:

   • General Motors stopped using Flint's water due to corrosion of their machinery.
   • Dozens of people contracted a form of pneumonia known as Legionnaires' disease.

4. What caused the change in water quality in Flint, Michigan:

   • City officials decided to stop fully treating the water to save money.

5. Data that help hydrologists predict floods:

   • Snowpack
   • Impermeable land area

6. What clean water regulation establishes the basic structure for regulating discharges of pollutants into U.S. waters:

   • Clean Water Act

7. Courses a student should take to become a hydrologist:

   • Statistics
   • Life science

8. Water filtration methods that require the use of a membrane or filter:

   • Reverse osmosis

9. Describe the Clean Water Act and mark TRUE or FALSE:

   • Regulates pollutants discharged into surface waters: TRUE
   • Covers both surface and ground waters: FALSE (that's the Safe Drinking Water Act)
   • Funds sewage treatment plants: TRUE
   • Authorizes the EPA to establish minimum standards for tap water: FALSE (that's the Safe Drinking Water Act)

10. CAUSE of water pollution:

    • Effluent from factories
    • Soil erosion

11. The Clean Water Act funded the creation of which:

    • Sewage treatment plants

12. Agency primarily responsible for administering the Clean Water Act (CWA) in the United States:

    • Environmental Protection Agency (EPA)

13. NOT a component of the Clean Water Act (CWA) aimed at regulating water quality:

    • Clean Air Standards (CAS)

14. Value of t in the investigation:

    • Solve the equations: For Site A: \(15 = 2t + 5 \Rightarrow 2t = 10 \Rightarrow t = 5\) months.

      For Site B: \(17 = 3t + 2 \Rightarrow 3t = 15 \Rightarrow t = 5\) months.

• 5 months
