Dynamics and interaction of organic carbon, turbidity and bacteria in a karst aquifer system 

 -  Hydrogeology Journal, 14(4), p.473-484, 2006 .
<br/><br/> The dynamics of organic carbon (OC), turbidity, faecal indicator bacteria and physicochemical parameters was studied in a karst system near Yverdon, Switzerland. Online measurements and sampling were done at a swallow hole draining an agricultural surface (the input), and two groups of springs (the outputs)that often show bacterial contamination. A fluorescent tracer that was injected into the swallow hole during low-flow conditions first arrived at the springs 10-12 days after injection; the total recovery rate was 29
