Sunshine powers water pumps in Africa (adapted fromhttp://www.waterforall.org/stories)-

Marta Njamsa is 18 and like so many women and girls in developing countries, Marta was tasked withthe time-consuming chore of collecting water. In January, Water For All donated a solar water pump totheir village.

Marta said, "Before the Sun Pump, we had to walk eight kilometres to the nearest village to get waterand used a hand pump. It was always breaking. Now Marta obtains clean drinking water with thesimple turn of a tap.

The Sun Pump uses the power of the sun to drive a pump that is capable of producing between 8,000-30,000 litres of water a day. Each pump is powered by three solar panels.


14/30

Mbu, a teacher at the school where the Sun Pump was installed said, "Water has made the school intothe center of the community. People in the community used to have to collect water from far away butnow, we not only have water for the school but people come on weekends to wash clothes as well."

4.1 Generally, people tend to consider boys to be physically stronger than girls. Why do youthink it is that women and girls instead of the men and boys in Martas village weretasked with the difficult task of collecting water? (2)

4.2 One litre of water weighs one kilogram. If the Sun Pump produced 8000 litres a day andeach female could only manage to carry a maximum load of 15 kg, how many femaleswould be needed to collect the 8000 litres of water? (2)

4.3 The water is pumped up from below the ground. Explain how the water got to beunderground in the first place. (2)

4.4 Will this underground source of water ever run dry? Explain. (2)

4.5 Are you able to suggest other ways in which the community could collect rain water. (2)

4.6 The Water For All Project wants to ensure that the pumped water is clean anddrinkable. They instructed the science students at school that they must regularly testfor impurities such as carbonates, nitrates and nitrites. They must also test the pH of thewater, making sure it is not too acid, nor too alkaline. Explain how you would go abouttesting for (a) carbonates, (b) nitrates and (d) nitrites. Also explain how you would testthe (e) acidity level of the water. (8)

4.7 Mention one way in which you would make acidic water drinkable. (2)

4.8 How do you think the lives of the people and the plant life of the village would change

now that they are able to get water from a tap close by to their homes instead of havingto walk kilometers to collect it. (4)

4.9 Almost all civilization started close to a river (or clean water source).Why is water soimportant for life? How would we survive without it? (4)

4.10 What is Fracking? Give a pro and a con of implementing this in rural communities. (5)

QUESTION 4

4.1 Traditionally males were hunters and they often had to leave home for days in the hunt for meat.

Women tended to stay at home nurturing babies and children. Their traditional jobs included

collecting wood and water. Water was required daily for cooking, cleaning and drinking. (2)

4.2 15 kg water 15 L of water. Therefore 8000 L / 15 L = 533.33 people. But since we cant ever

have 0.33 people, we need 534 women to carry a load of 8000 L. (2)

4.3 Water collects on the ground and seeps through to find its way into water below the

ground. (2)

4.4 No. The total amount of water in the hydrosphere is fixed, but water moves readily between

various compartments through the processes of evaporation, precipitation, and surface and

subsurface flows. There may be imbalances of input and output in particular areas, which will

manifest as drought or flooding. (2)

4.5 Build dams (large scale). Erect rain water retaining tanks that are fed by downpipes of

houses (small scale). (2)

4.6 Impurities, how to identify and treat

a. Carbonates:

To identify a carbonate, you mix it with an acid and pass any gas evolved through lime

water. A milky precipitate indicates CO2is released.

b. Nitrates:

Devarda's alloy (Cu/Al/Zn) is a reducing agent. When reacted with nitrate in sodium

hydroxide solution, ammonia is liberated. The ammonia formed may be detected by its

characteristic odor, and by moist red litmus.

c. Nitrites:

Use a urine test kit (purchase at local pharmacy) to check for presence of nitrite is the

water. Any pink discoloration of the test pad indicates a positive reaction which means

nitrites are present.

d. pH determination:

Use litmus paper. If it turns red water is acidic. If it turns blue, water is alkaline.

(8)

4.7 Calcium Carbonate, another name for precipitated chalk can be used to reduce excessacids. We

call this process neutralization. (2)

4.8 Having access to a water source that is only a tap turn away would allow people to grow flowers

and plants successfully. They would save hours in their day that before would have been

spent on water collection. (4)


29/30

4.9The human body is more than 80% water. All our bodily systems and functions require water to

operate normally. We also need water is cleanse our outside bodies as well as the clothes that we

wear. Water is also required for cooking, nurturing vegetable gardens and watering of plants. We

use water for recreation (swimming pools, boating, catching fish in dams etc). We could not

survive long without water. (4)

4.10 Fracking is a process where a strong jet of water, containing a cocktail mixture of chemicals, is

pumped underground in order to fracture rocks (shale) apart. These broken rocks then release gas

that was trapped inside it. The gas is caught and used to make oil and petrol. Pro: Fracking creates

many jobs in impoverished rural communities. Con: Fracking runs the risk of contaminating the

groundwater. (5)
