Water and Young People – Linked to the Future

The international Stockholm Junior Water
Prize contest aims to encourage young
people’s interest in issues concerning
water and the environment.
The award is given annually for an outstanding
water project by a young person or a small groupof young people. With this, the competition
seeks to inspire young people to a continued
engagement for water and the environment.
While the global water environment remains
in peril, the future depends on our ability to
manage this life-sustaining resource. Today’s
youth are indeed tomorrow’s leaders and must
be encouraged to pursue water-related careers
or risk further erosion of our scarce supply. In
Stockholm, the young finalists experience a busy and full week that will include meeting top world water experts, participating in seminars, visiting research and technicalfacilities and attending cultural and social events.
The finalists at the international Stockholm Junior Water Prize are the winners ofnational SJWP contests. The national and international competitions are open to
young people up to the age of 20 who have conducted water-related projects focusing on local, regional, national or global topics of environmental, scientific, social or
technological importance.

Hydrocarbon-degrading Microorganisms in
the Port of Mar del Plata and an Applicationof Bioremediation

Water Treatment With Free-floating Aquatic Plants

By José Agustín Ares, Mayra Lagarde, Eva de Migueland Laura de Rosa

Increased phosphate levels in natural water bodies have a large
impact on the environment. Humans are one of the main contributors to the increased amount of phosphate in waterways
through the release of partially treated wastewater. The wastewater often has large quantities of nutrients, including phosphates.
Nilmini tested and compared the ability of Salvinia auriculata and Azolla filiculoides to absorb phosphates from waterof two different phosphate concentrations and volumes. The
plants were placed in separate nutrient-enriched solutions,and the phosphate concentrations of the solutions were tested every day. Both plants significantly reduced the amountof phosphate in the water, but the Azolla was generally more
effective. A promising value of the free-floating aquatic plants
is that they may be composted and used as fertilisers.
The results of this study show that free-floating aquaticplants could be utilised as an effective, environmentallyfriendly and inexpensive tool for reducing the effects of phosphate overload in the water environment.

The economy of Mar del Plata, a seaside city, depends largely
on tourism, the fishing industry and the functioning of thecity’s port. Due to diesel oil leakage and cleaning of the ships,
the port’s water is highly contaminated.
The group has studied the contamination of diesel oil,which is a mixture of hydrocarbons, e.g. policyclic aromatichydrocarbons (PAH), and a possible method to ameliorate itin the water. After having determined the amount of PAH in
two places of the port, they compared the results to a zone
considered free of contamination. The group proved theexistence of hydrocarbon-degrading bacteria (HDB) in orderto determine if the technique called bioremediation could
be applied. Bioremediation uses the metabolic potential of
microorganisms to degrade hydrocarbons.
The group was able to measure the amounts of phosphates and ammonium, which is necessary in order to use
the bioremediation technique. They concluded that the application of the bioremediation technique could be the solution
to the problem of pollution in the port of Mar del Plata.

Household Wastewater:
A Second Life is Always Possible

By Fabrice Fanou-Ziaka, Ariel Francis Lawson andAdonis Megnizoun
Water is critical to life, but water supplies are unfortunately distributed unequally and water scarcity is a big problem in many
parts of the world.
The group emphasise the importance for nations ofstressing the consequences of excessive use of water, andthe benefit of recovering wastewater. The project focuses on
African countries, with a particular focus on Benin. The group
found that it was necessary to put in place water purification
plants and encourage households to be equipped with sumps
where wastewater can be collected, treated and reused.
Besides the practical benefits from water purification
plants, the expected results from the project are that new
behaviours regarding water are adopted, a research and action
programme is functioning and the project participates in environmental protection actions and wastewater treatment.

Water Education and Awareness Promotion
in Cameroon: A Youth Audience Approach

By Majorie Andzongo, Elizabeth Atang and Ferdie Musenja
The overall objective of this group’s project is to generateawareness, understanding and appreciation of water issues in
Cameroon, identify gaps in establishing adequate clean andsafe water, and reduce the recent outbreak of water-borne
diseases in the country.
The group, in starting a project to create awareness aboutbiodiversity conservation in Cameroon, observed that water
could not be neglected. Therefore, they introduced theWater and Education Promotion campaign. With its focus
on children and youth, the campaign was seen as a methodfor developing a sustainable diversity within the region. The
planned actions of the group included the use of songs,
poems, stories and games to carry out water education andawareness in schools and communities in the region. The
group visited several stakeholder groups, interviewed staff
and collected resource materials.
Some of the achievements of this campaign thus far are theestablishment of a Nature’s Club, participation at workshops
and seminars for children and teachers, and the production ofbooks, audio cassettes, radio and television programmes.

The Bioremediation of Phenol Using
the Pseudomonas Putida Bacteria

Control of Eutrophication of Coastal Waters by Using
the Clam Gari Solida (Gray, 1828) ( Mollusca Bivalvia ):A Natural Filtration Technique

By Keira Hodkinson and Christina Norris
Phenol is a highly corrosive and moderately toxic chemical.
It is used in pesticides, air fresheners and in the petrochemical industry. It is one of the most common pollutants in theaquatic environment. The Pseudomonas putida is a genetically modified bacteria which convert phenol to carbon dioxide and water.
Christina and Keira have investigated under which conditions the bacteria are most effective. They tested how thebacteria would react to the different temperatures of 26°C,
30°C and 34°C. They also experimented with different kindsof second layers in the sample containers. Christina and Keirafound that at 26°C the population of bacteria grew the fastest.
The use of rubber beads as a second layer also proved to
be an effective way to increase the bacteria population. The
beads could also be washed and reused, while a liquid could
only be used once.
This method of bioremediation was shown to be an effective way to clean aquatic environments from phenol and isprobably useful also on a large scale.

Experiment and Research of “Black and Grey Water
Separating” Treatment of Household Sewage and
Mid-Water Regeneration

By Chen Haobin, Wu Jiawei and Pan Jingyi
Household sewage is mainly composed of “black water” –resulting from urine and faeces – and “grey water” – resulting
from bathing and domestic washing. With their project, Chen,
Wu and Pan proposed separating, at the household level, theblack and grey water and treating it via a counter culture andacclimatisation of bio-film. They explored how to optimise thetreatment of household sewage, both so that the ultimate
impact on the environment would be minimised, and so that
beneficial components could be reused.
As part of their project, they also conducted an overview ofwater and sewage treatment in small and medium-sized cities
in the Zhujiang River Delta and learned that it is either inadequate or rarely practiced. Their black and grey water separation treatment process could be an efficient, energy saving
and easily applicable form of household sewage treatment.

By Sergio Danilo Julio Galleguillos andRodolfo Lazaro Poblete Villalobos
Aquaculture enterprises are increasing rapidly at both local
and global levels. Sergio and Rodolfo have concentrated on
one of the consequences of aquaculture in Chile. As a resultof the intrinsic processes of the cultures, organic matter (OM)
is produced and accumulated in the marine sediments.
This can lead to environmental problems such as eutrophication. Eutrophication is the process by which a body of water
becomes enriched in dissolved nutrients that stimulate thegrowth of aquatic plant life, usually resulting in the depletionof dissolved oxygen.
Sergio and Rodolfo proposed the use of a mollusc called
Gari solida as a filtering tool at the industrial level to reduce
the OM discharge in order to avoid eutrophication of thecoastal waters. Through practical experimentation and a statistical analysis of the results, they determined the amount of
OM deposited in samples of marine silt, with the presence
and absence of clams, in order to determine the feasibility ofusing Gari solida as a filtration tool.
They showed that it can be used in both closed and open
aquaculture systems that could be favoured by the naturalfeatures of the mollusc.

The Level of Nitrate in the Subsoil Waterof a Danish Island

By Jesper Roed Sørensen
Clean drinking water is essential for a healthy population.
Although everyone in Denmark has access to clean water,
the need to drill deeper into the ground to access it reveals
a big problem: pollution by fertilisers and pesticides. When it
rains, these infiltrate the surface and gain access to the subsoil
water, or groundwater.
Jesper has studied the increasing level of nitrate in the Danish subsoil water as a side effect of the enormous increase in
the level of fertiliser used on the Danish fields since the 1950s.
By using a spectrophotometer, he has measured the concentration of nitrate in the subsoil water belonging to a small
farm which has been polluted for many years. The results
showed that the level of nitrate was over the standards set by
the national Danish health and environmental institute, andshould therefore be monitored closely. One possible solution
is to plant trees around the wells so that they can absorb thenitrate with the roots over the years.

Specific Properties of Waves From High-speed Ferries
in the Coastal Area of Tallinn Bay:An Application of the Cnoidal Wave Theory

By Reio Põder
The Baltic Sea is the largest brackish water body in the worldand has a particularly vulnerable marine environment. Wakes
from large high-speed ferries can cause serious environmental problems to the sea, such as severe shoreline erosion,
harm to the aquatic wildlife and damage to structures andarchaeological sites. The fast ferry traffic may even adversely
impact the marine ecosystem.
The main purpose of Reio’s project is to identify the possible differences between waves from high-speed ferries andwind waves, and to establish possible excessive influences ofship waves on the local environment. The recorded profilesof leading waves of wakes from high-speed ships were compared to theoretical profiles of cnoidal and linear (sine) waves.
Maximum velocities of water particles in cnoidal waves arelarger than in sine waves with the same height and length.
Results showed that specific features of cnoidal waves andtheir possible dangerous influence on the marine environment
become evident when waves are very long. Both the lengthand height of waves generally increase with the ship speed and
it is therefore necessary to impose speed restrictions to prevent
adverse environmental impacts of fast ferry traffic.

1,2,3 – Processor-supported Drinking Water Analysis

By Stefan Bartlewski
How can chloride, sulphates and calcium in beverages be
determined fast and simply? Stefan developed a method, asimple titration, for which he only needs measuring flasks,
pipettes and a conductivity measuring instrument.
In his project, Stefan aimed to test his Three-Point-Conductivity-Analysis method thoroughly in order to improve it
and examine whether the procedure is applicable to determine quantities of other substances. He adds twice a surplusof titration to a sample solution. The results are calculated bythree values: the conductivity of the origin solution and the twovalues after the precipitation. By this he shows that it is possible to establish proof of quantitatively hydrogen carbonate(HCO3), chloride (Cl-), sulphate (SO42 -) and calcium (CA2+).
Series of measurements with commercial mineral water
showed that the results of this simple method come very nearto the declaration on the label. This analysis can also function
in strongly sugary beverages such as soft drinks as well as be
automated easily.

IsraelFluorescent Microbial Sensors for
Toxicity Monitoring in Water

Italy

By Ron NeumanIn the Jungle of Mineral Waters

Many water use systems in the world today suffer from thethreat of possible chemical contamination. In his study, Ron
examined the available methods for identification of suchcontaminations and then worked to improve some of thesemethods.
Today two types of microbial sensors are in use, either
using a global response of an organism, or highly specificreactions. The former sensors suffer from inappropriate sensitivity, while the latter have excess specificity. Ron has worked
at developing a sensor that avoids these two extremes. The
goal was to find engineered bacteria with differential sensitivity that is readily available and cheap. These two elements
make it relevant for less developed countries with deficiencies
in laboratory infrastructure to use the method.

By Stefania Caputo, Federica Moretti and Monica Salvadori
The consumption of bottled mineral water has increased inrecent years. Stefania, Federica and Monica wanted to examine whether the current trend of switching from tap water tobottled water can be justified by a higher quality and safety ofmineral waters. They aimed to provide information about thecharacteristics of water and analyse the provisions and makea chemical-physical and bacteriological analysis in order todefine the quality and safety of mineral waters in commerce.
They have also studied the legibility of the labels on thebottles and concluded that only 25% of the bottles attained“good” or “sufficient” with regard to information given anddimension and space on the labels. The analyses made, showthat the microbiological and organoleptic quality depends onconservation conditions and on the time passed from bottling.
They determined that the quality of the examined mineralwaters is close to the chemical composition of normal drinking water picked up in stratum (65% of tap waters). A guidefo the purchase of mineral waters has also been elaborated
by them.

For Protecting the Life Sustaining Groundwaterof Miyako Island: The Development of an
Environmentally Friendly Organic Fertiliser Utilising
Phosphorus Accumulated in the Soil

By Tsutomu Kawahira, Daisuke Sunakawa
and Kaori Yamaguchi
The island Miyakojima does not have surface water resources
and relies solely on groundwater for its freshwater needs.
About 65% of its land area is used for agriculture, and thegroundwater supply is therefore polluted with nitrate nitrogen resulting from the commercial fertiliser used in farming.
The group decided to investigate and develop an environmentally friendly organic fertiliser, with the ability to recycle thehigh density of non-soluble phosphorus accumulated in thesoil by using bagasse (the dry, fibrous residue remaining after
the extraction of juice from the crushed stalks of sugar cane),a biomass resource.
The group selected and isolated a microorganism that could
produce, from a soil consisting of weathered Ryukyu Limestone,organic acid to be used as a phosphorus dissolving bacterium.
The group concluded that by using the organic fertiliser developed for the soil of Miyakojima Island, it is possible to recycle
soil-accumulated phosphorus and reduce the nitrate contamination of the groundwater from the use of chemical fertiliser.

Studying of the Level of Contaminationof the River Suderve’s Basin and Estimationof its Environmental Conditions

By Jelena Bazar and Natalya Buko
The study of river basins is a holistic approach to the study ofwater and environmental problems. It has the advantage ofincluding everything that influences the river both upstream
and downstream.
Jelena and Natalya have done a study of the ecologicalstate of the basin of the river Suderve. They used bioindicatory methods and chemical analysis to determine the ecologicalstate of the river. Water samples were takenfrom five different sites, and the results
show levels of nitrate and phosphateconcentrations that exceed thepermissible levels. The concentrations of organic substances also
showed a higher level then thepermissible.
Besides the chemical andbiological analysis, the study also
focused on investigating anthropogenic influences in the basin andnature-protective actions.

LatviaDo Not Believe Your Eyes! (ColorimetricMeasurement of Phosphates’ Content in Water as a
Method for Identifying Point Sources of Pollution)

By Maija Gutke and Ž anete Sproge
The first impression of a water body may be deceiving. What
seems to be clean and safe water could be polluted. One canjudge the presence of sewage in a water body from the concentration of phosphates, since synthetic detergents found inwastewater are composed of them.
Maija and Žanete took water samples from visible sewage
discharge points and measured the concentration of phosphates. They used the colorimetric method – a quantitative
chemical analysis by colour – to measure the phosphate,
which they found to be high. Using this method, they thus
made it possible to monitor natural water bodies and establish other point sources of pollution in a nearby lake.
They found out that the concentration of phosphateions in the lake was also high and was caused by a previously unknown sewage discharge. Maija and Žanete further
investigated the sewage impact on the eutrophication of thelake, and concluded that the lake’s self-purification abilities
prevented eutrophication even where the concentration ofphosphate ions and organic matter was increased.

MexicoWater Silos: An Alternative to Save Wateron Agriculture

By Miguel Oscar Chan Dzul
Large amounts of water can be saved in agriculture. Miguelhas studied the characteristics of radishes in a community
near Valladolid in Mexico.
To satisfy the water needs and to compensate for the lossof water due to evaporation throughout the day, an averageof 110 litres of water is used for every 10 m2 of cultivated land.
This water volume increases the more the crops grow.
In order to demonstrate the savings that can be achievedin agriculture, Miguel created two soil beds after a techniquecalled ka’anche’. He used them with soil from the same bankand cultivated radishes in both of them, using equal amountsof horse manure as fertiliser. One of the soil beds was also
equipped with cylinders of newspaper to reduce the loss ofwater through filtration and evaporation.
Test results showed that from the use of newspaper, a
50% water savings was achieved even though radish production was the same in comparison to the traditional farming.

The Effects of a Water Passage on the Habitabilityof Stagnated Lakes

Environmental Quality and Public Health Implicationsof Sources of Water Supplies at Awka Area of Nigeria

By Aaron Oostdijk and Stephan de Regt

By Chioma Maryann Agbasi and Adaobi Ukamaka Okeke

Het Veerse Meer is a lake which used to be directly connected to the sea, but due to a major flood it was cut off fromthe sea by two big dikes in order to control the water level.
This caused the lake to stagnate and the number of species todecrease dramatically. When a saltwater area is cut off fromthe sea, the water becomes still and the chloride concentration will drop, giving the animals that live there a lessenedchance of survival. This has happened to Het Veerse Meer.
The project of Aaron and Stephan is about the effects ofa recent structure developed to create a controlled flow ofwater between the lake and the open sea, on the salinity andits fluctuations and by that the habitability of the water. The
salinity should ideally be 13 grams of salt per litre chloride.
That is not achieved according to Aaron and Stephan’s measurements, although the number of species has increased andthe concentration of salinity is stable.
The structure has thus improved the habitability of thewater of Het Veerse Meer and is recommended for application in other countries. The major problem for the animals
in the water was thus not only the level of salinity but its
fluctuations.

In Awka area in Anambra State, Nigeria, the lack of clean water
for domestic use is a problem.
In this study Maryann and Adaobi collected water samples
from these sources and analysed it for physical, chemicaland biological parameters. Some data indicate threats topublic health and are a result of pollution or contaminationfrom floods, erosion and waste disposal. Faecal coliforms
and Escherichia coli bacteria were present in the samples at
objectionable levels.
To avoid the negative effects on human health, Maryann
and Adaobi recommend all water be treated before drinking
and that personal hygiene becomes better when handling foodand water. They urge everyone in the community to take there
responsibility when handling water. Hopefully this will lead to asafer use of the common water resources.

NorwayBugårdsdammen

By Petter Nord, Per Christian Olsen and Kim Anders PetterssonBugårdsdammen is a 125 -year-old artificial pond in Sandefjord, Norway that is used for recreational purposes. During
winter, the ice layer on top of the water hinders oxygen fromentering the pond and result in fish kills.
Petter, Per and Kim Anders wanted to find out whether
there is a way of getting oxygen into the pond and thereby
improving the living conditions of the fish. The pond is also
threatened by the overgrowth of algae due to people feeding
ducks; both the food and the duck excrement are full of nitrogen, phosphorus and other nutrients. To measure the oxygenat several depths and locations in the pond, the group usedan oximeter. For evaluation, analytical and reference purposes, the group used a report about classification of freshwaterproduced by Norwegian Environment Agency (SFT).
The group concluded that it was possible to provide oxygen to the pond with the help of a compressor. By placing thecompressor under ground level with a cover on the top to let
air out, big temperature fluctuations would be avoided.

PolandInfluence of the Waste-dumping Site in the Village ofSiedliska on the Quality of Water in the Local Wells

By Izabela Dowolnia and Agnieszka Pukszta
Waste-dumping sites do often have a large impact on thelocal environment and can be a severe hazard to groundwater
resources if not managed correctly.
Izabela and Agnieszka have investigated how a wastedumping site in the vicinity of the villages Siedliska and Chrzanowo in Poland may have affected the groundwater usedby inhabitants of the two villages.
This was done by analysing local wells in the area to test
if the water is suitable for drinking. Both physiochemical andbacteriological properties of the water from six wells in thearea were examined. They concluded that the water fromthe wells in the area is not suitable for drinking. As a result,the students urged the inhabitants to switch to the available
water supply system. The study also included a survey concerning the awareness of the water quality and its impact on
the environment and health. This resulted in an appeal to theauthorities to continue with the campaign to raise awarenessfor water-related issues in the villages.

Some Features of Formation of Groundwater
Used for Drinking Water Supply in Turukhansk Village

By Natasha Chutova
Throughout the history of the Turukhansk region, no hydrogeological or geo-ecological studies were conducted to investigate the groundwater used for drinking water supply.
The aim of Natasha’s project was to study formationsof groundwater used for drinking water supply, determine
human-induced impacts on the hydrosphere, and analysenatural processes to protect groundwater against pollution bysurface runoff. Her test results and analyses described somefeatures of the formation of groundwater used for drinking
water, located the aquifer feed zone and identified environmental pollutant impact on groundwater. The chemical
analysis showed that the groundwater content in Turukhansk
village remained unchanged throughout the period of its use
for drinking water supply. It is not polluted by municipal waste
thanks to the screening role of a clay confining bed.

The Eurasian Otter, a Bioindicator Species?

By Raquel Cano Domingo and Yolanda Carcía Moreno
Many ecological problems can be foreseen by studying indicator species which are sensitive to changes in their naturalenvironment.
Raquel and Yolanda have investigated whether the Eurasian otter can be used as a bioindicator of the water quality inrivers. Over a long period, the otter population had decreased
but is now coming back to the rivers in Catalonia.
To see if it is possible to determine a relationship between
the recovery of the otter and improved water quality, they
made several water quality analyses on different sites along
the river Cardener. The water quality turned out to be very
poor, which made them look for other explanations for theincrease in otters.
During recent years the introduction of immigrant species,
which are capable of living in degraded habitats, have become
the otter’s stable diet. This lead them to the conclusion that theotter is not in itself an indicator of poor water quality. Instead
its population decrease indicated a limiting of the food supply.
A diminishing fish population in the rivers can be caused bypoor water quality, but can also have other causes.

8South Africa
Alien Buster 1,2,3

By Jacques Deacon
Trees of the Prosopis species are among the most widespreadinvasive trees in arid and semi arid zones of the world. The
current Prosopis invasion covers 1.8 million hectares of South
Africa and causes myriad environmental problems. Prosopis
invasions closely track underground water aquifers and have anegative impact on the scarce groundwater resources.
Current eradication strategies usually cost more than theland itself. The purpose of Jacques’ project was to develop an
economical and effective apparatus suitable for mechanical,
biological and chemical control methods.
Alien Buster 1 was found to be effective to gather seedpods that then could be destroyed through exposure tobiological agents in the form of beetles (Algarobius prosopis/Neltimius arizonensis), or used as fodder. Alien Buster 2
releases seed feeding beetles into the canopy of the tree
where the seedlings are. Application of herbicides revealed
Alien Buster 3 to be effective for foliar herbicide application,
cut stump and stem injection and basal bark methods usedat present on Prosopis.
This project revealed great potential for income generation from the good qualities of invasive species, economicaland safe eradication operations and job creation in poor
communities.

SwedenDrip, Drop, Splish, Splash – a World Water Book

By Ulrika Andersson, Sandra Johansson, Charlotte Nauclér
and Agnes Willén
The importance of water-related problems is indisputable,
and though the young generation will have to deal with manyof them, they often lack knowledge about water.
Ulrika, Sandra, Charlotte and Agnes decided to developed
a book about water for children between the ages 6–11. After
studying different aspects of water-related environmental
problems, they started with the book. To find out what children know about water and what kind of material is alreadyavailable, they sent out a questionnaire to primary schools.
From this they decided to focus the book on five different
areas: acidification of lakes (which is a big problem in the
Scandinavian countries), water conservation, water abroad,
unequally distributed water resources and the water cycle.
During the writing process the text was read to focus groupsof children to make sure it was comprehensible. Ulrika, Charlotte, Sandra and Agnes also sought guidance from authors,illustrators and scientists.

The Environmental Impact of Aluminum Sulfate andSalicylic Acid Treated Poultry Litters on Forage
Production and Watersheds

Water Contamination Reduction by Flora (primarily
by knotweed) in La Duong Village, Hatay Province,
Vietnam

By Brandon Fimple

By Trieu Tien Chuan

Eutrophication resulting from phosphate pollution is one of
the most costly water quality problems in North America
today. It causes algae overgrowth, which affects drinking water
quality among other problems.
Brandon has in his research evaluated the effects of treated poultry litter fertilisers on forage production, runoff water
phosphate levels and Closterium algae growth in an effort tofind an environmentally protective litter treatment with effective algaecide properties.
Five poultry litter treatments were tested in each of thethree procedures of the experiment. The results showed thatthe salicylic acid treatments increased forage production anddecreased the algae production, but did not decrease the phosphate levels in the runoff water. The data indicated that thesalicylic acid might have had a direct effect on the algae cells.
Overall, the data indicated that the 10 % alum treated litter
was the most effective litter treatment as it did not adversely
affect forage production, significantly reduced runoff phosphate levels and adversely affected algae growth.

The development of new businesses and economic activities
is often positive for the livelihoods of local people because
it creates new jobs and income possibilities. Unfortunately, it
often also creates local or even global environmental degradation.
In the village of La Duong, water resources are experiencing increasingly serious pollution. This can be attributed to therapid expansion of animal husbandry (about 4900 pigs), local
liquor distillation, and additionally, ten enterprises that operatearound the village.
Trieu Tien investigated possible solutions to the problemof water pollution in the village, where industrial pollution
contaminates the underground aquifers on which the villagers are dependent for drinking water.
The most important measure, he suggests, is the use ofplanted knotweed. As an activity, planting knotweed together
can help raise the public awareness of water issues and joint
participation in activities which help to save the village water
resources.
