Rumbula is a bathing area on the Daugava River in Riga, Latvia. It is one of 58 official bathing sites in Latvia designated under Cabinet Regulation No. 692 of 28 November 2017. Water quality is monitored and assessed according to European Directive 2006/7/EK requirements. The bathing site's water quality classification is based on microbiological indicators including E. coli and intestinal enterococci, as well as observation of blue-green algae blooms.

Water

The Daugava River, an inland water body. Physical and hydrological characteristics are described in the document but specific quantitative measurements of area, depth, and flow rate are not provided in the extracted text.

Location

Rumbula, Daugava River, Riga, Latvia.

Water Quality

Water quality is classified on a four-class scale: excellent, good, sufficient, or poor. Classification is based on four years of monitoring data using statistical analysis. Microbiological quality is assessed using E. coli and intestinal enterococci as faecal pollution indicators. Excellent quality: E. coli ≤500 CFU/100 ml, intestinal enterococci ≤200 CFU/100 ml. Good quality: E. coli ≤1000 CFU/100 ml, intestinal enterococci ≤400 CFU/100 ml. Sufficient quality: E. coli ≤900 CFU/100 ml, intestinal enterococci ≤330 CFU/100 ml. Swimming is not recommended if E. coli exceeds 1000 but does not exceed 3000 CFU/100 ml, or if intestinal enterococci exceed 300 but do not exceed 500 CFU/100 ml. Swimming is prohibited if E. coli exceeds 3000 CFU/100 ml or if intestinal enterococci exceed 500 CFU/100 ml.

Risks

Blue-green algae (cyanobacteria) blooms may occur. Excessive algal blooms prohibit swimming. Pollution sources include faecal contamination from wastewater and diffuse pollution from urbanised areas, traffic, atmospheric pollution, and agricultural land use. Pollutant loads are influenced by land use types in the catchment area and from populations not connected to centralised wastewater collection and treatment systems.
