MassDEP’s New Method for Analysis of Volatile Petroleum Hydrocarbons (VPH) by Gas Chromatography/Mass Spectrometry (GC/MS) in Support of Response Actions under the MCP


Date and Time:    Tuesday, February 28, 2017 from 1:00 to 4:00 pm

               Place:    Massachusetts Department of Environmental Protection, Central Regional Office, 8 New Bond Street, Worcester, Massachusetts 



MassDEP has recently published a new analytical method and associated CAM protocol (WSC-CAM-IV C) which can be used as an option for measuring volatile petroleum hydrocarbons (VPH) in aqueous and soil/sediment matrices.  The method utilizes gas chromatography/mass spectrometry (GC/MS) to measure the collective concentrations of volatile aliphatic and aromatic petroleum hydrocarbons and the target analytes, benzene, toluene, ethylbenzene, xylenes, naphthalene, and MTBE.  This method is known as MassDEP “VPH by GC/MS.”    


This training is being offered by MassDEP free of charge to laboratory staff (analysts, project managers, and QA personnel) as well as chemists who are responsible for the evaluation of analytical data quality. It is focused on the specific provisions, biases, and data adjustment steps of the new method.  LSP Continuing Education Credits are not available for this training.


Training participants are encouraged to review the new method and QC protocol prior to the training available here:

Training Instructors: 

Elizabeth Denly is a Senior QA chemist at TRC with over 27 years of experience. Ms. Denly is responsible for providing QA/QC oversight as well as chemistry support in support of a variety of environmental investigations including contaminant ambient air  monitoring, delineation, human health and ecological risk assessments, risk-based soil cleanups, and remediation programs.  Ms. Denly has worked closely with MassDEP on several projects, including development of the VPH by GC/MS method.  She provides MassDEP with support regarding CAM protocols, and the evaluation of CAM-generated data and under MassDEP’s direction has lead work to update the CAM, create new CAM protocols, and provide training for laboratories. Ms. Denly has been an active member of several Work Groups within MassDEP, including the APH, EPH/VPH Revisions, Data Usability, and the original Data Quality Enhancement Work Groups.


John Fitzgerald received a B.S. and M.S. in civil engineering from the University of Massachusetts at Lowell, and is a Registered Professional Engineer in Massachusetts. He has been employed by the Massachusetts Department of Environmental Protection (MassDEP) since 1980, where he oversees the assessment and cleanup of sites contaminated by oil and hazardous materials.  Mr. Fitzgerald oversaw the development of the VPH and EPH Methods for MassDEP’s Bureau of Waste Site Cleanup (BWSC) and authored the BWSC guidance document Characterizing Risk Posed by Petroleum Contaminated Sites: Implementation of the MADEP VPH/EPH Approach.
