Water: Laboratory Certification
Expedited Method Approval Process

EPA can use an expedited process to announce the approval of new drinking water analytical methods in the Federal Register. The process provides laboratories and water systems more timely access to new alternative testing methods than the traditional rulemaking process.

Expedited Method Approval Requirements
There are several requirements that must be met before a new method can be approved using the expedited process.
- Public water systems must be required by federal regulation to monitor for a contaminant that is an analyte in the new method.
- Drinking water regulations must list at least one approved method for the contaminant (i.e., a method that was approved using the rulemaking process).
- A comparison of the new alternative method to the approved method(s) must show the new method to be equally effective in determining the concentration of the contaminant.
New methods may be submitted for evaluation under the Alternate Test Procedure (ATP) program. A new method can be considered for approval using the expedited process, if it has performance characteristics that fall within the range of performance characteristics obtained by the methods listed in regulation for the same contaminant.
