1. Scope and Application
1.1 This is a general purpose method that provides procedures for determination of
organic compounds in finished drinking water, raw source water, or drinking water
in any treatment stage. The method is applicable to a wide range of organic
compounds that are efficiently partitioned from the water sample onto a Cis organic
hase chemically bonded to a solid silica matrix in a cartridge or disk, and sufficient
volatile and thermally stable for gas chromatography. Single-laboratory accuracy and
precision data have been determined at two concentrations with two instrument
systems for the following compounds

A laboratory may use this method to identify and measure additional analytes after
the laboratory obtains acceptable( defined in Section 10)accuracy and precision data
for each added analyte
1.2 Method detection Iimit(MDL)is defined as the statistically calculated minimum
