Worked Solution & Example Answer:Clean water is an essential service to the home - Junior Cycle Home Economics - Question 5 - 2016
Step 1
Name three treatments carried out on water before it enters the mains supply to the home. Give the reason for each treatment named.
Answer
-
Screening: This process involves removing larger objects from the water.
-
Settling: This allows solid particles to settle at the bottom, thereby clarifying the water.
-
Filtration: This step removes smaller particles like grit and stones from the water, ensuring better quality.
-
Chlorination: Chlorine is added to destroy harmful bacteria present in the water, ensuring it is safe to consume.
-
Fluoridation: This treatment prevents tooth decay by adding fluoride to the water supply, thus promoting dental health.
Step 2
Suggest ways in which water can be conserved in the home.
Answer
-
Repair Leaks: Fixing leaks in taps and pipes can save a significant amount of water.
-
Avoid Wasting Water: Avoid using running water unnecessarily, such as when brushing teeth or washing dishes.
-
Use Appliances Wisely: Utilize economy or half-load settings in washing machines and dishwashers to minimize water use.
-
Short Showers: Taking shorter showers conserves more water compared to baths.
-
Flush Wisely: Use less water per flush and be mindful of toilet usage.
Step 3
Name two different causes of water pollution and state how each one affects the environment.
Answer
-
Oil Spills: Oil spills can result in severe contamination of water bodies, leading to the deaths of aquatic life and disrupting ecosystems.
-
Animal Slurry: Runoff from farms containing animal waste can lead to eutrophication, resulting in bad smells and illness in both humans and animals.
Step 4
Describe the procedure to follow when water pipes burst in the home.
Answer
-
Turn off the Water at the Mains: This stops the flow of water, preventing further flooding.
-
Call a Plumber: It is important to seek professional help to assess and repair the damage.
-
Drain the System: Completely drain the affected water pipes to avoid water accumulating.
