Scientists use microorganisms to clean up Moravian river
Scientists in the country’s Olomouc region have poured around 400 kilogrammes of microorganisms into the River Blata in a deliberate effort to reverse the impact of a recent contamination, which has so far killed hundreds of fish. The effort, costing around 140,000 crowns, is viewed as a viable alternative to using chemicals, with the microscopic organisms expected to eat their way through the human and animal sewage, which leaked into the river from a farm in nearby Seničce in early June. Police are currently investigating the circumstances surrounding the leak; locals have already removed 700 kilogrammes of dead fish from the waters. The cleanup effort is set to take several weeks, while scientists warn that it may take several years for the river to fully recover.
