     Brief Method Summaries
     The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the US EPA, APHA, AS and NEPM. In house
     developed procedures are employed in the absence of documented standards or by client request. The following report provides brief descriptions of the analytical procedures employed for results reported in the
     Certificate of Analysis. Sources from which ALS methods have been developed are provided within the Method Descriptions.
