Niko Putkinen sipping the hand illustration from the pipe gushes water discipline cash the fields surrounded by the aquifer.
Yes, this is it Finnish clean up the groundwater! Geological research center special researcher, working Tubes of whoop is.
in Kurikka the soil is exceptional, what has caused the problem, inter alia, Kurikka centre of the buildings. The cliff-top is a thick clay-silt layer, which is not very position, and it is a lot, up to thirty meters.
the Clay-silt layer is however good, because it does not pass water. Hazardous materials are therefore not transported for example from the fields under the location of the ground water.
Special researcher Niko Putkinen praises Kurikka groundwater, perhaps Finland’s cleaner.Pasi I/Yle
Tubes mentions that groundwater clean picture of it, too, that in Kurikka city need it Kuusisto nook and cranny in the environment of the well with little cleaning before its transition to the use of water kurikka types of homes.
in These regions, the country’s depths, hiding in the exceptionally large aquifers.
the Deep aquifers found a bit like accidentally 2010. The geological survey of finland GTK started exploration drilling kuusisto hole in Kurikka water supply and already in the first drilling, it was discovered that this is not quite the usual groundwater area.
It was clear, in fact, already in the first deep hole.
an Estimated 1.5 billion years ago resulting in a huge gorge in the are assumed to be so much water, that it will be covered in the future, Vaasa and Kurikka urban water needs.
Where will the water come?
Kakkurin sources kyrö river in the discipline fund water gushes from the groundwater observation tube from the surface of the earth, so to speak, freely, ie, the Tubes according to the talk at the time arteesisia of groundwater.
When clay and moraine through the drilled hole, the water is discharged there naturally on their own pressure, he describes the phenomenon.

the corresponding types of the groundwater observation tubes have been drilled in Kurikka into the environment of about 130 pieces. Drilling and pumping is intended to determine, inter alia, the extent of deep aquifers in reality is and how much there can be water sustainable in the future, consume and utilize.
– let’s just Say that five years from now we have an idea of what this body contains.
currently, the issues will also cause it, where the water transported into the deep groundwater. Because the clay layer is impermeable to water, directly on earth it rains water does not accumulate to perform normally.

One of the study target are areas that are more than a hundred meters from the sea level. One of these is the journal of the mountain area, where water is assumed to descend into the valley in the fertile soil of contribute by.
– This [groundwater deposits] can already be called a geologist for a miracle. Clay comes under his old deep worn bedrock ruhjesysteemi, which must have been the ice age at the time of suitable sediment. And specifically ground water to think of suitable sediment, i.e. there is sand and gravel, where water can be stored, Tubes of describes.
Where does the water go?
Vaasa Water has been involved in Kurikka study of the GTK, the South Ostrobothnia Ely centre, and in Kurikka water supply with the year 2014. Vaasa dreams cover its future water needs, in particular, that the same of ground water occurrence.
the Water has been found now about half of the amount required, namely, more work is still ahead.
in Utah take currently raw water kyrö river surface water. Water purification is expensive, because the river water quality is uneven. Cloud pond in the Vaasa Water is in addition to approximately two months of operating stocks.

We have to find an alternative, because Vaasa is not a water, if these two above mentioned happens. Discipline dip should be therefore our main source of our future, said the Vaasa Water network in the master Jari Jantunen .
the Original dream was that kurikka law of water would be received to Vaasa until already in 2025. However, it seems that goal a little late, because licensing set out in his own time.
studies continue all the time and next summer in the area move koepumppaus and groundwater flow modelling. Senior researcher Niko Putkinen told me she had to get help in the modeling phase, inter alia, the canadian colleagues, who have expertise and similar instances of the study.
Why is water interesting?
Another identical or equally extensive bedrock depressions resulting ground water deposits in Finland is not elsewhere met. Although Kurikka under the resting body of the scope is still as a whole the secret the water of the soil strata is much.
At the moment the test area size is about 10 x 15 miles. Illustration from the pipes reach the fullest almost 110 meters until the cliff assurance with.
the Big maaperäkairalla machines and their users have done their own work discipline cash for two years. Each hole will be installed groundwater observation pipe, which is outfitted groundwater level monitoring by the sensor and ”jar”, which manages the measuring arrangement, the information recording and upload wirelessly to databases.

discipline cash used in GTK’s innovation is based on the technique of bottom water surface of the track – in the future, anyone can follow the website from the ground water situation in the region almost in real time.
Cooperation with Finnish geologists make the technical terms of british colleagues, and therefore, for example, the BBC visited Kurikka situation (switch to another service) a year ago.
Niko Putkinen enthusiasm for the geology of the point does not go unnoticed. He commends their work also its social side and the local people.

– I think I know who the only host in these areas, when people here the pihoillakin really drilled. Here, the oral word is the oral word and the fact kurikka types are allowed to be proud of, to convince the Tubes.
