As a project QA chemist at TRC, Ms. Denly is responsible for providing QA/QC oversight in support of a
variety of environmental investigations including risk-based soil cleanups, remediation programs,
delineation, contaminant ambient air monitoring, and human health and ecological risk assessments. Ms.
Denly has provided this oversight under different state and federal regulatory programs, including
MassDEP, NYSDEC, NJDEP, TCEQ, and USEPA Region I, Region II, Region Ill, and Region V. In this
role, she is responsible for the following:
Data Usability/Data Validation: Ms. Denly routinely performs or provides oversight of data
usability assessments or data validation for a variety of analytical parameters including volatile
organic compounds (VOCs), semivolatile organic compounds (SVOCs), pesticides,
polychlorinated biphenyl (PCB) Aroclors, metals, wet chemistry, PCB homologues/congeners,
dioxins/furans, specialty analyses including gas chromatography/mass spectrometry/selective ion
monitoring (GC/MS/SIM) and various air analyses.
Preparation of Project-specific QAPPs: Ms. Denly has prepared QAPPs for a wide body of
regulatory programs, including NYSDEC, New York City Department of Environmental Protection
(NYCDEP), and USEPA Regions | and Il. This experience includes the more detailed format in the
Uniform Federal Policy for QAPPs, currently required by many of the USEPA Regions. In addition,
Brownfields QAPPs are routinely prepared using Quality Assurance Guidance for Conducting
Brownfields Site Assessments, September 1998, EPA 540-R-98-038.
Analytical Laboratory Audits: In order to ensure that analytical laboratories are capable of
producing data of the quality needed to meet the objectives of most methodologies, Ms. Denly
typically performs a very detailed on-site laboratory audit prior to contracting with our
laboratories. These audits allow TRC to ensure that the laboratory staff members are technically
competent in the methods they perform, are following acceptable QA practices, and are in
compliance with the various methods. All audits include interviews with staff, observations of
techniques, examination of records, and an inspection of the facility and equipment. Ms. Denly
has developed internal audit checklists for an extensive list of preparation and analytical methods
(including the most commonly used SW-846 methods and USEPA air methods) as well as
general QA laboratory procedures (i.e., sample receiving, glassware washing, bottle preparation,
data management, SOPs, and performance evaluation studies).
Field Audits: Ms. Denly periodically performs field audits of TRC’s projects. Especially with
larger programs, performance of field audits at the onset of the project ensures that any potential
issues are resolved early. Typical field audits performed by Ms. Denly consist of an evaluation of
various procedures versus SOPs and regulatory requirements. In general, the procedures
evaluated during a field audit include sampling of various media, decontamination, field
screening, calibration, collection of QC samples, documentation, sample labeling, and chain-of-
custody. Audits are conducted by interviewing field staff, observing their techniques, examining
