The Netherlands has developed an efficient water quality monitoring system utilizing high-performance liquid chromatography with diode array detection (HPLC-DAD). This innovative approach acts as an early warning network for detecting pollutants, crucial for protecting surface waters. Researchers from KWR Water Research Institute detail the evolution of the method from a simple analytical technique to a national platform, emphasizing harmonization, shared databases, and swift responses to contamination incidents, like the pyrazole case. Such strategies may serve as a model for other nations.
