New Analytical Method for Volatile Organics in Air NJDEP-LLTO-15- 3/2007
March 2007

Important Notice

The laboratory certification process for the new NJDEP Low Level Method TO-15 air analytical method for volatile organics is currently in progress. As more laboratories are certified, the Department will require all Method TO-15 analyses to be conducted using the new NJDEP low level air analytical method. A notice will be posted on this web site when the required change to the new method will be in effect. It is recommended that interested parties periodically check this web site for additional updates on this issue.
The issuance of this new method is the first step in the formal progression to lower the reporting limits for the majority of the volatile organics required by NJDEP. This will move the reporting limits for some compounds closer to the health based criteria.

The NJDEP Site Remediation Waste Management SRWM) Program has developed criteria for a Low Level Volatile Organics Method for air sampling and analysis that will be used in place of the currently certified method USEPA TO-15 Method. The new method is designated as NJDEP-SRWM Low Level USEPA Method TO-15, March 2007 (NJDEP-LLTO-15 - 3/2007 [pdf 406 Kb]). The specific details of the requirements can be obtained directly from the NJDEP-LLTO-15 - 3/2007 method which is posted on the NJDEP Web site at http://www.nj.gov/dep/srp/guidance/vaporintrusion/.
