Going the Extra
Mile: Efficiency
and Expertise
PES was founded in May 1988 in response to a
perceived need by
engineering firms for technical support in on-site data collection and
interpretation. Since then, PES professionals have earned a
reputation for efficiency and dependability in 26 different
states. Many environmental consulting firms now rely on PES
for their field sampling and field analytical support.
The PES reputation was built on the
competence of our personnel - competence that comes from years of
professional experience. From supervising quality control
functions to managing whole projects, from authoring technical papers
to participating in EPA collaborative-method validation studies, PES
scientists have hands-on experience in numerous aspects of
environmental services. Areas of staff expertise include
devising site-specific sampling and analytical plans, writing
analytical specifications under the U.S. EPA Contract Laboratory
Program, and providing expert witness services for litigation cases
that involve the interpretation of analytical data.
