Salaspils Pilsētas Peldvieta

Latvia River 0 - Not classified

Salaspils pilsētas peldvieta is a bathing site on the Daugava River in Latvia. The site is subject to monitoring and water quality assessment according to European bathing water directives. Water quality is evaluated based on microbiological criteria, including E. coli and intestinal enterococci indicators, as well as consideration of cyanobacterial blooms. The bathing water profile document provides a detailed analysis of factors affecting water quality and management measures to maintain or achieve at least sufficient water quality standards.

Water

The Daugava River, an inland water body. Physical and hydrological characteristics are described in relation to the Daugava River and Riga Hydroelectric Station reservoir.

Location

Salaspils city area on the Daugava River in Latvia.

Season

Water quality monitoring is conducted across four bathing seasons over four years for long-term assessment.

Water Quality

Water quality is classified using a four-class scale: excellent quality, good quality, sufficient quality, and poor quality. Monitoring is based on four-season data. Long-term quality assessment uses statistical analysis of E. coli and intestinal enterococci counts. Excellent quality: intestinal enterococci ≤200 CFU/100 ml, E. coli ≤500 CFU/100 ml (95th percentile). Good quality: intestinal enterococci ≤400 CFU/100 ml, E. coli ≤1000 CFU/100 ml (95th percentile). Sufficient quality: intestinal enterococci ≤330 CFU/100 ml, E. coli ≤900 CFU/100 ml (90th percentile). Swimming is not recommended if E. coli exceeds 1000 but does not exceed 3000 CFU/100 ml and/or intestinal enterococci exceed 300 but do not exceed 500 CFU/100 ml. Swimming is prohibited if E. coli exceeds 3000 CFU/100 ml and/or intestinal enterococci exceed 500 CFU/100 ml.

Risks

Cyanobacterial blooms pose a risk. Excessive cyanobacterial proliferation prohibits swimming. Fecal pollution from point and diffuse sources is a concern. Point sources include wastewater discharges. Diffuse sources relate to land use, untreated wastewater from residents not connected to centralized sewerage systems, urbanization, traffic, and atmospheric pollution.
