Water Supply and Quality Practice
WATER SUPPLY AND QUALITY
Test PRACTICE TEST
QUESTIONS AND ANSWERS WITH COMPLETE
SOLUTION
1. If a new study indicates that the PDSI is showing severe drought conditions in a region
similar to the Dust Bowl, what actions might local governments take to mitigate the
effects on agriculture and water supply?
Increase water usage for irrigation without restrictions.
Implement water conservation measures and drought-resistant crop
programs.
Ignore the PDSI data as it is outdated.
Focus solely on urban development and ignore agricultural needs.
2. Which impact does prolonged drought have on migration patterns?
Infertility of the soil makes farming impossible, forcing people to migrate to
more hospitable locations.
People's homes fall into disrepair and become uninhabitable, leading them to
find new homes.
The decrease in an area's natural beauty drives people to seek out more
picturesque locations.
Communities attempt to attract new migrants to help bring prosperity back to
the region.
3. Explain how hydrophytes like cattail obtain nutrients from their environment.
They absorb nutrients through their roots from the soil.
They filter nutrients from the air.
They get nutrients directly from the water in which they grow.
They rely on symbiotic relationships with soil bacteria.
4. Creosote bush roots release a chemical that limits the growth of white bursage roots.
,This often results in a desert landscape climax community dominated by regularly-
spaced creosote shrubs. This process is called?
Facilitation
Inhibition
, Priority effect
Tolerance
Allelopathy
5. What were the two main factors that contributed to the Cape Town water crisis as
mentioned in the provided text?
Increased rainfall and population decline
Population growth and decreasing rains
Overuse of water and improved conservation techniques
Climate change and ancient water management practices
6. Explain how drought can indirectly affect mental and behavioral health in
populations.
By improving access to clean water
Through increased food security
Due to stress and anxiety related to resource scarcity
By enhancing community resilience
7. If a region experiences a flood lasting for two weeks, what potential effects could this
have on the local water bodies and human health, considering the information from
the text?
Increased water availability with no health risks.
Contamination of water bodies leading to health issues.
Improved water quality due to natural filtration.
No significant impact on water bodies or human health.
8. Explain how decreased rainfall can lead to groundwater pollution and the types of
microorganisms that may proliferate as a result.
Decreased rainfall reduces water levels, leading to higher concentrations of
pollutants, including viruses, protozoa, and bacteria.
Decreased rainfall increases the flow of surface water into groundwater,
diluting contaminants.
, Decreased rainfall has no effect on groundwater quality, as it only affects
surface water bodies.
Decreased rainfall promotes the growth of plants, which filter out
contaminants from groundwater.
9. Plants that derive moisture from groundwater, more or less not directly dependent on
rainfall:
Hydrophobic
Adiabatic
Vadose
Phreatophytes
Apogeotrophic
10. Explain how the 2012 drought in Ohio affected local utilities and their ability to meet
water demand.
Utilities were able to increase water supply to meet demand.
Utilities like Delco Water struggled to meet the increased demand.
Utilities implemented new technologies to improve water quality.
Utilities experienced no significant changes in water demand.
11. What significant period does the Holocene Climate refer to, and what major
developments occurred during this time?
The last 100 years, marked by industrialization.
The last 10,000 years, characterized by the emergence of agriculture and
civilizations.
The last 5,000 years, focused on urbanization.
The last 50,000 years, dominated by hunter-gatherer societies.
12. What percentage of freshwater is used for industrial purposes according to the
breakdown of freshwater use?
8 percent
22 percent
