As the temperatures rise and the summer season kicks in, regional hygiene stations across the Czech Republic have commenced their assessments of water quality in swimming areas. These evaluations provide valuable information to swimmers regarding the safety of the water before they take a dip, ensuring a pleasant and risk-free swimming experience.

Jana Loosová, the director of the Regional Hygiene Station in Liberec, emphasizes the importance of making informed decisions when choosing swimming locations. For unfamiliar bodies of water, individuals are encouraged to observe the surroundings and look out for signs of potential contamination, such as agricultural runoff. Moreover, Loosová suggests conducting simple amateur water analyses, such as observing the movement of green particles in a PET bottle filled with water. The behavior of these particles can indicate the presence of cyanobacteria or algae, which can cause skin irritations, eye inflammation, or more severe health issues if they produce toxins.

To assist swimmers in determining water quality, Loosová recommends consulting the website of the relevant regional hygiene station for information on local swimming areas. For those planning vacations in other regions of the country, the website Koupacivody.cz provides comprehensive information on all bodies of water in the Czech Republic. Additionally, information boards will be available at monitored swimming locations to inform visitors about water quality and any potential risks.

The monitoring process involves collecting water samples from various swimming areas, including popular sites like the Mšeno dam in Jablonec nad Nisou. The samples are analyzed in laboratories to assess the presence of cyanobacteria, viruses, and bacteria associated with fecal contamination. The results, which are compared throughout the swimming season, provide insights into the development of cyanobacteria, algae, and microbial contamination in the water.

Hygiene officers utilize specialized equipment during the sampling process, including funnels for collecting water samples and determining cyanobacteria levels, Secchi’s disks to assess water transparency, and devices to measure pH and water temperature. The comprehensive monitoring efforts aim to ensure that swimmers can enjoy clean and safe swimming environments across the country.

By staying informed about water quality and following the guidance provided by regional hygiene stations, individuals can make informed decisions about where to swim, helping to protect their health and well-being during the summer swimming season.
