DMMP Users Manual

The 2009 Edition of the Users Manual is undergoing a major revision.  Until that revision is complete, the 2009 version is provided here with markups denoting urgent updates.  Click HERE for the 2009/2013 markup. 

Contact the DMMP for any clarifications or questions.

Some Important Updates

Don't Forget:

  • Applicants must submit a Sampling & Analysis Plan for approval by the DMMP before sampling and chemical analysis. 
    • If you don't get your SAP approved, you risk having to resample and/or retest before a suitability determination can be made.  See Chapters 2, 3 & 4 of the Users Manual for more information. 
    • As always, call or e-mail if you have any questions at all!
