Every day, we drink, use and bathe in water. Yet water contamination is on the rise, another example of our vulnerability to environmental degradation, so dramatically highlighted by the COVID-19 pandemic. The good news is that it’s easy to check water quality, and so avert the danger by ourselves.
When we started preparing for an experiment, we asked ourselves the following question: if we could check the water for just a few minutes, could we control its quality? And the answer was “Yes”.
You can buy rapid test kits on the Internet in just a few clicks (they cost from 200-500 hryvnias – €6-15). They are also sold at pet stores.
24 Channel’s website journalists also reached out to the State Agency for Water Resources of Ukraine and the Interregional Office of Protective Arrays of Dnipro Reservoirs to test water under their experts’ surveillance.
Anton Biriukov, a leading chemist of the State Agency for Water Resources of Ukraine, explained that this rapid test kit can identify nitrate and nitrite indicators. However, the concentration of nitrates and nitrites, as well as other compounds, needs to be measured more precisely at a laboratory through a fully-fledged analysis.
Soil and surface and groundwater always contain nitrates and nitrites. This is caused by both natural nitrogen cycles and anthropogenic environmental impact.
Biriukov noted that you have to take water samples with preserved properties to check water quality at a laboratory. This means the water has to be fresh.
According to leading chemists, as a rule, the concentration of different compounds in water is low. However, if a quick test shows a bright colour, it means that water is contaminated.
What are the results?
The water taken from the three experiment sites in general turned out to be suitable for use and drinking. The concentration of nitrates and nitrites in the water bodies is within normal limits – up to 10 mg/L.
However, it should be noted that if nitrate and nitrite levels exceed 10 mg/L, water is not recommended for drinking and using in hygiene procedures.
The experts warned that rapid test kits should not be compared with professional equipment, because using test strips is a portable method that has large margins of error and uncertainty.
“The test strips measure six indicators, and our laboratory identifies approximately 15-18 indicators,” explained Biriukov.
According to Biriukov, fertilisers used in agriculture, as well as enterprises that discharge different substances into water bodies, are key sources of water pollution with nitrates and nitrites.
“Soils are treated with fertilisers. Then it rains, and related substances get into the groundwater. They then migrate and come into surface water, in particular to human wells. Moreover, enterprises use various substances for their needs and illegally discharge them into the surface water. And all these activities are not regulated. There are a lot of substances, but mainly these are pesticides used by the agricultural sector,” added the expert.
Is water in Ukraine safe?
Oksana Konovalenko, a representative of the European Union Water Initiative Plus for the Eastern Partnership Countries (EUWI+ 4 EaP), said that in Ukraine, approaches to water resource management have been changed. To date, the Dnipro River Basin Management Plan has been developed.
Konovalenko identified untreated wastewater from public utility companies and the agricultural sector as major causes of water pollution. In particular, pesticides are toxic for animals and microorganisms present in the water.
“If we take certain measures, the situation will not change immediately, but sooner or later, everything will start working. The key objective is to avoid the entry of pollutants into natural water. The best and the most expensive actions that should be carried out include the improvement of all the treatment facilities – public utility facilities and those involved in production processes. Moreover, the amounts of substances used for treating soils have to be established. This will decrease the amount of harmful substances that get into water bodies. Our experts develop agricultural practices and regulations that we have to follow,” added Konovalenko.
How the situation could be improved
The European Union Water Initiative Plus for the Eastern Partnership Countries (EUWI+ 4 EaP) promotes water policy reforms in the six Eastern partner countries: Armenia, Azerbaijan, Belarus, Georgia, Moldova, and Ukraine. One of its key objectives is to support Ukraine in the development of the Dnipro River Basin Management Plan. More specifically, the project aims to support partner countries in bringing their national policies and legislation into line with the EU Water Framework Directive and other multilateral environmental agreements.
