Naktonggang Chilseo Point Algae Warning Issued at 'Caution' Level

Elevation to Alert Level Following Interest Stage Declaration on the 8th

The Nakdong River Basin Environmental Office announced on the 22nd at 3 PM that it has issued an algal bloom alert at the Chilseo point of the Nakdong River at the ‘Warning’ level.

The alert was issued because the harmful cyanobacteria cell count at the Chilseo point exceeded the criteria for issuing an algal bloom alert at the ‘Warning’ level (10,000 harmful cyanobacteria cells/ml for two consecutive measurements).

This is analyzed to be due to the continuous rise in water temperature at the Chilseo point caused by abnormal high temperatures (28.0℃, an increase of 1.9℃ compared to the previous week) and the inflow of nutrients from intermittent rainfall, creating an environment favorable for algal growth.

The Nakdong River Office has communicated the algal bloom alert at the ‘Warning’ level to related agencies and urged local residents to refrain from water-related activities such as fishing and swimming, as well as from harvesting and consuming fish and shellfish, due to the escalation of the alert level.

Algae monitoring, which was originally conducted once a week on Mondays, will be increased to twice a week on Mondays and Thursdays starting today. The office will disclose the status of algal occurrences and response measures, strengthen guidance and inspections of water pollution sources such as open-air compost and wastewater discharge facilities, and increase patrols along the main river to reduce the inflow of pollutants into the water system.

Each water purification plant plans to shorten the activated carbon replacement cycle and strengthen the operation of advanced water treatment facilities (ozone + granular activated carbon) to ensure the supply of safe tap water to local residents.
