treatability study will be met. The Contractor should include
standard test procedures (ASTM, EPA, etc.) with all
recommendations for testing. Procedures should be described for
all tests which do not have formalized procedures. The project

Contractor suggestions. Non-standard test procedures should be
approved by the Government prior to use. These procedures may
require analysis of several samples to determine if the method is
repeatable, precise and accurate.
The SAP must be provided to the contract laboratory as well as
the QA laboratory along with the listing of DQOs. The method of
funding the QA laboratory must be considered at the scope of work
