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

‘I i R C Elizabeth A. Denly

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
