EPA Method 551.1:
DETERMINATION OF CHLORINATION DISINFECTION BYPRODUCTS, CHLORINATED SOLVENTS, AND HALOGENATED PESTICIDES/HERBICIDES IN DRINKING WATER BY LIQUID-LIQUID EXTRACTION AND GAS CHROMATOGRAPHY WITH ELECTRON-CAPTURE DETECTION

Summary:
A 50 mL sample aliquot is extracted with 3 mL of MTBE or 5 mL of pentane. Two ?L of the extract is then injected into a GC equipped with a fused silica capillary column and linearized electron capture detector for separation and analysis. Procedural standard calibration is used to quantitate method analytes.

Scope:
This method1-9 is applicable to the determination of the following analytes in finished drinking water, drinking water during intermediate stages of treatment, and raw source water. The particular choice of analytes from this list should be a function of the specific project requirements.
