Quality of rivers vis-à-vis pesticides in Brittany - Health impact

Interannual summary on the evolution of the quality of the stations monitored for pesticides, with regard to compliance with the regulatory limits set for the supply of drinking water. Available series: samples - sum of concentrations> 0.5 μg/l (frequency), compliance with EPA thresholds, compliance with EPA thresholds - maximum concentration, compliance with EPA thresholds - sum of concentrations, quantified active substances >0.1 (frequency), quantified active substances >2 (frequency), sampling - sum of concentrations>5 μg/l (frequency) and maximum concentration per substance.
