Sara is working on making her house more eco-friendly. She has a number of upgrades she wants to make such as replacing her toilet that uses 5 gallons per flush with a new toilet that uses 1.2 gallons per flush. She also wants to replace a leaky faucet in her kitchen. Finally, she would like to replace her old washing machine that uses 35 gallons of water per load with a new high-efficiency model that only uses 10 gallons per load.

If you can Answer using the answers to answer
Also I’ll give my answers if some aren’t here when I do mine GL
1. One human activity that has increased the amount of light in drinking water is urbanization and the construction of artificial light sources near water bodies. The water filtration method best suited to remove lead from the drinking water supply is activated carbon filtration. Activated carbon filters are capable of trapping and removing lead contaminants from the water by adsorption.
2. Benefits of an aquaponics system:
- Higher productivities per square foot compared to conventional farming.
- Potential failure points are reduced as the system operates in a closed-loop, minimizing external factors.
Drawbacks of an aquaponics system:
- Initial set-up costs tend to be higher due to the need for specialized equipment.
- Total water usage can be higher compared to conventional farming.
3. The two best courses for a student to take in order to become a hydrologist are statistics and physical science. Statistics will provide the necessary skills for data analysis and interpretation, which are crucial in hydrology. Physical science courses will provide a solid foundation in understanding the fundamental principles of hydrology.
4. Graywater refers to household wastewater that does not contain wastewater from toilets.
5. Raising livestock affects water resources negatively. Livestock generate significant amounts of manure, which can contribute to water pollution through nutrient runoff and contamination of water sources. The excess nutrients, such as nitrogen and phosphorus, can lead to eutrophication in water bodies, causing harmful algal blooms and oxygen depletion.
6. The Clean Water Act is considered to have had the greatest impact on water quality in the United States. It established regulatory standards and provided funding for the development of wastewater treatment plants, aiming to reduce water pollution. The Act has led to significant improvements in water quality, including the reduction of industrial and municipal discharge of pollutants into water bodies.
7. Cause of water pollution: effluent from factories and soil erosion.
Effect of water pollution: storage of drinking water and algae bloom.
8. The statement that supports the idea that aquaponics helps reduce the impact of human activities on the environment is "Reuse of fish waste reduces the use of fertilizers." In aquaponics, fish waste serves as a natural fertilizer for plant growth, minimizing the need for synthetic fertilizers that can leach into water bodies and cause pollution.
9. Reverse osmosis is a water filtration method that requires the use of a membrane or filter. It works by applying pressure to force water through a semipermeable membrane, effectively removing contaminants.
10. Regulates pollutants discharged into surface waters: Clean Water Act.
Covers both surface and ground waters: Clean Water Act.
Authorizes EPA to establish minimum standards for tap water: Safe Drinking Water Act.
Funds sewage treatment plants: Clean Water Act.
11. The change in water quality in Flint, Michigan was caused by city officials deciding to stop fully treating the water to save money. This decision led to corrosive water leaching lead from aging pipes into the drinking water supply, resulting in widespread lead contamination.
12. The two occurrences that happened because of Flint's water crisis are: General Motors stopped using Flint's water due to corrosion of their machinery, and dozens of people contracted a form of pneumonia known as Legionnaires' disease, which was linked to the contaminated water supply.
13. The two types of data that help hydrologists predict floods are snowpack and impermeable land area. Snowpack data provides information about the water content in snow, which contributes to spring runoff. Impermeable land areas, such as concrete or asphalt-covered surfaces, prevent water infiltration and increase surface runoff during heavy rain events.
14. Sara should replace the leaky faucet in her kitchen first. A leaky faucet can waste a significant amount of water over time, contributing to water waste and increased utility bills. By replacing the leaky faucet, Sara can immediately reduce her water consumption and decrease her environmental impact.
15. The Clean Water Act funded the creation of sewage treatment plants. The Act provided financial support for the construction and improvement of sewage treatment infrastructure, aiming to reduce pollution discharges into water bodies and improve water quality.
