Why is natural spring water better than processed water from a bored well?
Industrially processed drinking water and that of the water supply system do not entirely comply with the needs of the body since the water is cleaned via several procedures and often enriched with synthetic minerals. The human body is adjusted to drinking fresh living water that is purified by nature itself and has retained its organic structure. Processed water protects the tubing of the water system, household gadgets and against bacterial contamination, but does not support the microbiota nor provide essential natural minerals. Long-term consumption of industrial water may enhance diseases and chronic infections because processed water is not inherent to the body.
Spring water differs from the water of deeper layers by its chemical content. In the near-surface layers of groundwater with aerobic conditions and fast water exchange, the content of microelements is moderate. There are no such harmful or excessive elements that may be present in deeper layers (barium, ferrous iron, hydrogen sulfide, radionuclides, ammonium ions, methane, boron, excessive fluoride, and dissolved solids); in the upper layers, the content of fluoride is optimal. Regular overconsumption of highly-mineralised water can cause different health issues due to high salinity and certain microelements accumulating in the body.
In order to use the deeper layers of groundwater as a source of drinking water, the water is treated with methods such as aeration, filtration, and chemical processing. In certain cases, the aeration is followed by applying strong chemical oxidizing agents such as ozone (O3), chlorine (Cl2), or potassium permanganate (KMnO4) to ensure the final oxidation. In case of spring water, none of it is necessary.
Where does Lavi spring water come from?
The springs of Lavi village are located in Vinni Municipality, Lääne-Viru County, in the eastern part of the Pandivere Upland. Lavi springs border on the kames of Männikvälja with rheocrenes opening on the sides. Depending on the season and the amount of precipitation, the total discharge of the Lavi springs is 108–441 L/s. The resurgence of our spring is 20 to 30 litres per second. The relatively uniform temperature remains around 6 °C throughout the year.
The Pandivere Upland in the Northern Estonia spreads over 1,100 square kilometres and is located 80–130 metres above sea level. The area differs from the rest of Estonia for its terrain features and climate. The Pandivere Upland is a preglacial erosional upland that is clearly distinguishable from the hilly accumulative uplands of Estonia, formed during the Ice Age.
Autumn arrives earlier and spring later, and winter is longer than elsewhere in Estonia. Therefore, both the amount of precipitation and groundwater recharge from snowfall are bigger. There are no permanent rivers and creeks in the central part of Pandivere Upland: the water is absorbed into the ground where it is cleaned and mineralised when reaching the aquifer laying in the subsurface. The central part of the upland is surrounded by a circle of Estonia’s largest springs. Groundwater forces itself into the springs, many of which form the sources of our most significant rivers. Beneath the surface, there are several karst aquifers – groundwater reservoirs that feed the springs.
Water is filtered through the glacial moraine cover and the sedimentary rock formed in a shallow marine environment 0.5 billion years ago. The limestone bedrock which is situated 50–60 m higher than the surrounding lowlands consists of Ordovician and Silurian carbonate skeletons, that is, biogenic limestone. Biogenic limestone, together with the fossils, contains all the essential minerals.
One of the springs in Pandivere Upland are the Lavi springs, famous since ancient times as a source of good clean drinking water.
Lavi springs are located above vertical tectonic fractures, through which spring water rises to the surface in the Pakerort Stage and Tiskre Formation, two rock layers mainly consisting of sandstone and aleurolite. There, the rising water mixes with the upper part of the water horizon. The water of those systems, now intermixed and forced to the surface, has the best features of both groundwater and surface water: it is not as vulnerable to human activity as surface water, yet it contains no harmful substances like the deeper layers of groundwater.
Lavi spring water is a good source of minerals! Filtered by free-flowing through limestone and sandstone, Lavi spring water contains a considerable amount of calcium carbonate (also known as lime) and other natural minerals crucial for the human body. Calcium is especially beneficial for the 50+ age group in avoiding bone density loss.
Natural spring water that contains calcium bicarbonate may not help with the appearance of the coffee machine because of the build-up of limescale, but it protects your health. Ask yourself, which is more important?
