Therefore, experts recommend conducting water quality studies at least once a year, preferably twice in spring and fall.
Where are the dangers?
“Although our groundwater is protected from external contamination, it still requires constant and continuous monitoring of drinking water. Throughout Vilnius, tap water is safe and suitable for consumption, so city residents using centrally supplied water can rest easy thanks to its quality control. However, those who use the water from their own wells or wells should not forget to check it periodically, ”says Aurelija Baronienė, director of the Vilnius Water Laboratory.
According to her, the main risks to the quality of drinking water are for the owners of the wells. Water enters wells from groundwater, where environmental pollutants easily run off along with rainwater. The open construction of wells presents an additional risk, posing a risk of direct water contamination.
The report states that drinking water contaminated with pathogenic microorganisms (bacteria or protozoa) can lead to fever, nausea, vomiting, and diarrhea. Microbes are killed by boiling water, but if well water is contaminated with chemical contamination, neither boiling nor household filtration removes the chemicals from the water.
Surveys are paid
The company shares in the press release that when investigating the quality of well water, it is recommended to perform tests for the determination of iron, nitrites, nitrates, ammonia, manganese content and pH of the water, specific electrical conductivity.
For the study of well water it is advisable to carry out a microbiological test of water, nitrites, determination of nitrates and pH of the water, specific tests of electrical conductivity. Additional testing should be done immediately if changes are observed in the taste, odor, color, or water level of drinking water.
“Nitrogen compounds (nitrites and nitrates) released into water as a result of human economic activity do not give water a specific taste and odor, so it may appear safe for consumption. Unfortunately, such water is not uncommon in wells of the population, and these substances are dangerous for everyone, the most vulnerable group are babies and pregnant women ”, warns A. Baronienė.
The company’s website indicates that after the customer service is provided, a VAT invoice is issued and sent for payment of the service at the applicable rates.
A microbiological test of tap water, as published on the company’s website, will cost € 16.50. At that time, well water testing, including microbiological and chemical testing, will cost € 32.50.
The water can be brought to the laboratory by the residents themselves, but it will probably be necessary to call in specialists to carry out the investigation of the well, so in addition, according to the rate established by the company, it will be necessary to pay for its arrival. .
Renata Saulytė-Smalskė, communication manager for Vilniaus Vandenai, clarifies that specialists do not visit residents during quarantine, but residents can always bring a water sample to the company’s laboratory and perform the desired test.
“People sometimes have questions about taste or smell, which is why they study the water in various ways – usually they study how much iron or manganese there is, how many other elements. Here, just like in a blood test You can choose what you want to find out, ”adds R. Saulytė-Smalskė.
The company adds in a press release that residents who use water supplied by Vilniaus Vandenys can check the water quality themselves on an interactive well map located on the company’s website. By entering the residence address, each user can see from which well the water is supplied and what its microbiological, chemical and sensory parameters are.
Residents with their own wells can study water quality in Vilniaus Vandenai’s laboratory. Water samples can be delivered in the company’s laboratory to all natural or legal persons, regardless of whether they are Vilniaus Vandenai customers. The service can be requested by phone 1889 or by request free of charge by email. by mail [email protected]
Vilniaus Vandenys continuously monitors the quality of drinking water, conducts microbiological, physical and chemical tests of drinking water. 2020 A total of 20,005 tests were carried out in the company’s laboratory, which studies the water quality of the city of Vilnius and the districts of Šalčininkai, Švenčionys and Vilnius, which is 32 percent. more than in 2019.
