The New Jersey Department of Environmental Protection is the first state regulatory agency in the country to approve and certify the use of field analytical methods as part of their "Triad Approach," without compromising data quality and reliability.  Using UVF for real-time measurement is one such technique that can result in more time and cost effective site characterization and cleanup.  NJ DEP's Office of Quality Assurance (OQA) performed an on-site audit and required Sitelab to prepare a very thorough QA/QC package as part of their Environmental Laboratory Certification Program (ELCP).  This webpage highlights Sitelab's laboratory certification process and how we can be used for TPH applications in New Jersey.         

Laboratory Certification ID MA013

Laboratory Certification ID #MA013, Category Code SHW12.  Expiration Date: June 30, 2015.

    This was a first for Sitelab.  By approving the use of UVF field analytical methods, people can now use Sitelab Corporation to test TPH in replacement of conventional laboratory methods.  The certification process, however, wasn't easy.  It was expensive, time consuming and a lot of hard work. The DEP's Office of Quality Assurance required Sitelab to comply to the same, tough standards conventional fixed-based laboratories must adhere to.

     A 4-hour audit was performed at a DEP facility located in Trenton, where OQA scientists and  administrators watched how contaminated samples were tested and reported using Sitelab's UVF-3100 analyzer, including a number of quality controls performed to verify the instrumentation was operating properly and the test method was sound.

     Following the audit, Sitelab was then required to prepare a very detailed Standard Operating Procedure (SOP), supported by a QA/QC package with corrective actions taken for deficiencies identified during the audit.  Examples include five MDL studies performed, by testing 7 replicate soils containing low level concentrations of either fresh gasoline, home heating oil, crude oil and coal tar.  OQA also required all traceability records relating to UVF instruments and use of calibration standards, including copies of Certificates of Analysis, second-source quality assurance materials and other supporting documentation.

    "We have successfully used this field method and it allowed us to improve our understanding of the nature and extent of contamination by giving us real-time data and more sample results than we would have been able to afford using just fixed-lab analyses."  Nancy Rothman, Ph.D, CEO & Principle Scientist

Contractor uses Sitelab's mobile lab to monitor progress and define the extent of TPH on residential sites contaminated by home heating oil.  Direct push drill rigs are used to inject a solution of Nano Peroxide deep into the ground, which accelerates the natural bioremediation activity in the soil.

 QA/QC Data and Method Detection Limit Studies performed:

SOP tables with QA/QC info for NJDEP laboratory certification

Gasoline range organics results for soils with gasoline

Extended diesel range organics results for soils with fuel oil

Target PAH results for soils with coal tar

TPH-Oil results for soils with crude oil
