Do I drink clean water?

If you suspect groundwater contamination in your district or home well, the first step is to contact the water company, which often provides basic water quality information on bills or its website, where drinking water monitoring results may be published.

If the water source is managed by the city or municipality, you should contact municipal officials and ask them to publish the drinking water analysis results on the city or town website.

What should a water analysis include?

Regarding contaminants and chemicals commonly analyzed, smaller water sources typically test around 25–26 substances, while larger sources test up to 80. If the municipality uses fertilizers, pesticide testing should also be included.

It is important to realize that at least once a year, residents should request a comprehensive drinking water analysis that covers at least 100 to 300 substances.

What if I have my own well from which I drink water?

People who drink water from their own wells, especially in areas like Žitný Ostrov where many municipalities lack their own water supply and rely on private sources, should be particularly cautious.

In new developments where residents are entirely dependent on their own drinking water source, it’s critically important to recognize the potential vulnerability of that source to contamination. In Žitný Ostrov, residents might have neighbors with cesspools, and many are not connected to the sewage system — all of which are potential sources of drinking water contamination.

People who drink well water should have it tested at least once a year. Although it’s not a cheap process, it may be possible to coordinate with neighbors who have wells at similar depths and test together.

Isn’t the Water Day test enough?

Regional authorities organize one day a year for water sample analysis. It’s important to realize that even though the regional authority or water company may analyze your sample for free, it usually only tests for nitrates — just one out of up to 300 possible substances — to ensure safe water. A free analysis is not comparable to a comprehensive one.

Do I drink clean water?

1. Suspicion of contamination? Check water quality info with your water company or contact local representatives if it’s a municipal source.
2. Water analysis: Smaller sources test 25–26 substances, larger ones up to 80. Pesticide testing recommended when fertilizers are used.
3. Private well: Have your water tested once a year, especially in high-risk areas like Žitný Ostrov.
4. Water Day analysis: Free nitrate tests are limited; more is needed for a full analysis.
