F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 5055311Rivers are a means of rapid and long-distance transmission of pathogenic microorganisms (including fecal indicator bacteria and human enteric viruses) from non-point and point sources, posing a direct risk for human health. Pathogens are exchanged from the surface water to underlying sediments via hyporheic exchange, which delays downstream transmission and allows for immobilization via reversible filtration in the sediments to occur. Furthermore, accumulation and persistence of pathogens may be exacerbated in intermittent streams due to the extreme hydrologic regime of these ecosystems. Although pathogens are expected to accumulate within streambed sediments, especially downstream of a point source such as a waste water treatment plant (WWTP), direct measurements are rare. Moreover, it is unknown if pathogen persistence is a local phenomenon close to the point source or if the continuous deposition and resuspension of pathogens in streams results in net pathogen accumulation further downstream of the source.
