Cc. Team
This project will be managed and staffed from our Manchester,
NH office. Should the need arise, numerous additional field staff
are located in our Lowell, MA office which is less than 20 minutes
away from the site.
At no additional costs to the City, TRC is planning on assigning a
team of four field personnel to the project to ensure that there ase:
are multiple staff trained and oriented to the site. This will give a sufficient pool of staff to
respond as required.
One of TRC’s core values is quality. We have assigned an independent QAQC chemist to review
sample collection notes and analytical data for usability. TRC’s QAQC group operate asa
separate group from operations to insure their independence from the project outcomes.
Lisa Krowitz has over 25 years of experience in environmental analytical chemistry, providing
QA/QC oversight related to laboratory analysis, data review, data validation, and data usability.
She performs data validation and/or data usability evaluations of VOCs, SVOCs, PAHs, PCBs,
petroleum hydrocarbons, pesticides, metals, wet chemistry (e.g., cyanide and hexavalent
chromium), and radiological isotopes on a variety of matrices (aqueous, soil, sediment, air, and
tissue samples). Ms. Krowitz has extensive experience with oversight of analytical laboratories.
She also has experience in field sampling, soil gas surveys, field audits, and laboratory audits,
and in preparing QAPPs, specifically under the Uniform Federal Policy for QAPPs.
David Gill, PE will be the Technical Lead for this project. Mr. Gill has over 23 years of experience
in environmental testing and monitoring and works out of our Manchester, NH office. He has
worked in TRC’s Air Measurements group performing emission testing at a variety of local and
national facilities. He has experience in landfill gas emissions and control devices including the
tuning of landfill gas engines to maximize output while minimizing emissions on both new and
older engines. He has also performed well field balancing to maximize methane output which
allowed for a reduction in supplemental fuel use and provided better control of odors.
Jamie Stapleton, PG will be the project manager for this program. Mr. Stapleton has over 17
years of experience in environmental geology. As a Geologist and/or Project Manager he is
responsible for the proposal, coordination, execution and reporting obligations of
environmental projects under Licensed Site Professionals (LSPs) or Professional Engineers. His
expertise includes remedial system construction as well as system Operations & Maintenance
(O&M). Mr. Stapleton has worked for public utilities, transportation firms, major petroleum
corporations, real estate corporations, and municipalities.
