Collecting and Processing Stream Water Samples

Samples collected for chorophenoxy-acid herbicides and carbamates (NWQL schedules 2050 and 2051) use the high-pressure liquid-chromatography (HPLC) method. These synthetic-organic compounds in stream water interact with sediment particles through sorptive processes; therefore,it is important to separate the solid phase from the sample as soon
