Impact of oil spills on trout development
By Riina Kilpeläinen and Sanni Nieminen

Alonso and Marcos present an effective and natural way toremove boron pollution from water. Their research showsthat high concentrations of the aquatic plant algae Nostoc
sp., Chlorophita sp. and Lemna minor are able to remove
the boron from the water, which can then be extracted
for commercial use as an agricultural fertiliser.

Riina and Sanni's research demonstrated the destructive impact of oil spills on the development of Salmo
trutta (trout). They sought to learn whether the trout
could survive and spawn after an oil spill and foundmortality rates among oil exposed eggs to be very high.
Their observations showed that speed of oil exposure
significantly increases mortality rates, making fast oil spills
more dangerous to trout survival.

Wat...er you drinking?
By Omar Pappalardo, Angelica Mammoliti and Lara Miccoli

Fabian and Simon developed a low-cost, applicable andexpandable modular system of floating concrete pontoons that can help vulnerable areas protect themselvesfrom floods. Their design features hexagonal pontoons
made with highly stable thin walls produced from fibrereinforced concrete and a load-bearing structure forbuildings that can be used in flood-prone areas or on
an open expanse of water. The modular system can beassembled quickly and easily transported to the site.

Omar, Angelica and Lara investigated how individuals
consume, use and waste water. Through chemical,
physical and microbiological analysis and an algorithm tocalculate the daily water requirements per person, they
concluded that alternative water sources, such as rainwater for irrigation or household use, should be used.
They also researched the difference between tap andbottled water and found that, from a health perspective,
there was no difference between the two.

Innovative rooftop gardening to cool down theheat island effectBy Tetsuo Ogawa, Nao Wakisaka and Yuka Ishida

Chemical contamination of water systems is a major threat
to human health. Early identification and quick response to

The urban heat island effect makes life hotter and harderin many cities. Rooftop gardening can cool urban centres
down but is slow to catch on as the plants used canbe heavy, costly, and water intensive. Tetsuo, Nao, andYuka developed innovative, lightweight and water-saving
rooftop gardens using drought and climate resistant Zoysia
japonica plants. They also developed a soil-free system,
which uses recycled polystyrene and biodegradable
materials to insulate heat flux from rooftops.

Water treating with use of coagulation
By Margarita Dervine
The Latvian project applied laser analysis in an innovative
new way to evaluate water quality. The research showedthat the quality of water treatment is impacted by theconcentration of coagulation in the water. She concluded
that lower levels of coagulation concentration worsen thequality of water that undergoes treatment. Margarita’s
findings can be applied in future evaluations on water
quality treatment and can potentially be used to improvethe modelling of natural wastewater processes.

Pollution by Løkken Verk: How does pond waterpollution influence cell division in onions?
By Marianne Blikø and Katinka Kummeneje

In Mineral de la Reforma, Mexico, dirty wastewater flows
down from the river everyday. The wastewater is contaminated and needs to be treated in order to be reused.
The Mexican project innovated a new, cost-effective
and low-energy consuming alternative for domestic
wastewater treatment using natural and locally available
materials. The treated water produced in their projectpassed national quality standards.

The ponds of Fagerlivatn and Bjørnlivatn lay near an
abandoned mine. Marianne and Katinka performed theAllium test by cultivating onions in water samples fromthe polluted ponds for one week. The onions short, discolored roots and further disfigurement was observed.
Their research reveals metals from the mines have likely

Yangjae Stream, Seoul: A water quality
investigation
By Hee Ku Kang and Yong Kun Ko

AquaLibra is a new, purely natural water barrier design thatis controlled, activated and determined by the movementof the water body it is located in. It functions like a balance:
when seawater levels rises above a critical level, the surplus
water lifts up the barrier and a floodgate stops the seawaterfrom flowing into rivers or harbors. The mechanism does
not depend on complicated computer systems or humandecision-making. Possible applications range from small
tidal harbors to large cities in delta regions.

The Korean team investigated the Yangjae Stream withanalysis of both its physical condition and local perception of its health. Their tests show that the stream water
passed legal standards of pH and nitrate levels but
contained hazardous levels of bacteria, which made thewater no longer potable. Though public sentiment towards
the water quality, facility and ecosystems of the Yangjae
were positive, the students recommend further researchon the bacteria present in the stream.

Suitable substrates for sulphate-reducing bacterial
pollution from acid mine drainage treatment
By Jozef Molnár
Jozef Molnár investigated effective options to remove
dangerous heavy metals and sulphates from water
resulting from acid mine drainage (the outflow of acidic
water from mines). His research confirmed that glycerol,saccharose, glucose and whey are all suitable alternative
substrates of sodium lactate that can reduce bacterial
sulphate. Calcium lactate was found as the most efficient
option. Application of these findings can reduce costs andnegative environmental impacts to water globally.

Restoring water quality in the Segre River
By Guillem Pascual Pastó
Guillem Pascual Pastó investigated the sources of Segre
river pollution. He found dumping, run-off and excessive
irrigation withdrawals from agriculture to be the maincauses. The project concluded that more modern irrigation techniques, strict regulation of fertilisers, reduced useof hydropower and implementation of urban wastewater
treatment plan could restore water quality in the riverand its tributaries.

Tap water vs. bottled water in Sweden
By Åsa Omstedt, Anthony Abdulahad and Lisa Chung
Sweden may have the best tap water in the world. Yet,bottled water sales increase every year. Why? Does it taste
better than tap water? Is it healthier? Åsa, Anthony, andLisa examined bottled water in Sweden and determinedthat there is no difference in taste and health impact.
After measuring the carbon dioxide emissions associatedwith bottled water transport, they concluded that bottled
water in Sweden is unnecessary and negatively impacts
the environment.

Tapping freshwater from submarine sources
By Feride Ibraimova
The coastal area of Crimea needs freshwater. Feride
Ibraimova proposes that submarine freshwater sources inthe sea can be transmitted to the reservoir. She proposed
the construction of a large concrete tool (that looks likea big cup placed faced-down) would be placed above
the submarine freshwater source. A pipe for freshwater
would rise under its own pressure and transmit the water
to the reservoir. The proposed solution is economicallyefficient, environmentally friendly and requires minimal
power expenses.
