field notes and log forms, and inspecting equipment. Ms. Denly has developed internal field audit
checklists for soil sampling, groundwater sampling, surface water & sediment sampling,
decontamination procedures, calibration of water quality parameter measuring equipment and
photoionization detectors (PIDs)/flame ionization detectors (FIDs), x-ray fluorescence (XRF)
screening, immunoassay screening, proper documentation of field notes and field log forms,
sample labeling and chain-of-custody procedures.
e Standard Operating Procedures (SOPs): Ms. Denly has been responsible for the development
of field investigation SOPs for a variety of sampling procedures at TRC. All SOPs are generated
in accordance with the USEPA Guidance for Preparing Standard Operating Procedures (SOPs),
April 2007. Currently, Ms. Denly has assisted with and provided oversight for the development of
field investigation SOPs for soil sampling (including SW-846 method 5035A procedures for
VOCs), soil gas sampling, groundwater sampling, surface water & sediment sampling, test pit
completion, equipment decontamination, soil classification, water level and product
measurement, chain-of-custody, sample packaging & shipping, jar headspace, field
documentation, and water quality parameter calibration.
e Selection of Appropriate Analytical Methodologies: In order to ensure the objectives of the
project are met, Ms. Denly is responsible for working with the project team and laboratories to
ensure the selected methodologies will achieve the desired regulatory standards. Ms. Denly has
extensive experience with when it is necessary to request method modifications (i.e., decreasing
final extract or digestate volumes) or specialized analyses (i.e., SIM, PCB homologue analyses)
that can be performed to increase the sensitivity of various analytes.
e Alliance with Regulatory Agencies: Ms. Denly had worked extensively with MassDEP in various
capacities. MassDEP is a state regulatory agency responsible for ensuring clean air and water,
the safe management of toxics and hazards, the recycling of solid and hazardous wastes, the
timely cleanup of hazardous waste sites and spills, and the preservation of wetlands and coastal
resources. Select examples of relevant work projects in this experience area include the
following:
o 2010-Present: VPH by GC/MS: Ms. Denly is currently providing assistance to MassDEP for
the development of a protocol for the analysis of volatile petroleum hydrocarbons (VPH) by
GC/MS. She is responsible for providing MassDEP with a draft final version of this method.
Ms. Denly also assisted MassDEP with the implementation and development of a multi-
laboratory round-robin performance evaluation study for the final VPH by GC/MS
methodology and the development of a subsequent report for this study. Ms. Denly will be
assisting MassDEP with training for laboratories interested in implementing this method.
o 2016-Present and 2006-2007: MassDEP Data Audit Project: Ms. Denly is responsible for
performing review/evaluation of data packages for EPH/VPH/APH/TO-15 analyses from
laboratories selected by MassDEP as part of a Data Audit project to ensure compliance with
the methods and CAM. All laboratory reports which were reviewed were randomly selected
by MassDEP from different sites in Massachusetts. As part of the evaluation, she developed
worksheets that can be used in the future by MassDEP auditors for EPH, VPH, APH, and
TO-15 data. In addition, Ms. Denly provides MassDEP with a final report summarizing the
results of the data audits.
