Okay, somebody has to say it....

"Google search"

Also check university libraries and make use of the helpful professionals there.

www.nemi.gov is a good source for U.S. EPA methods.

Dave,

Accustandard has EPA methods for many of those constituents as PDF files. You have to slog through both the extraction methods and the analysis methods but they are the norm in the industry (in the US.)

Best regards.

As an FYI the detector list is definately not complete but those are the most common detectors in environmental labs for those analytes of interest in my experience.
