1) The document summarizes Norbert Iari's shadowing experience with Randy Kertes at Sadat Associates to learn about their environmental due diligence process. 2) Due diligence involves investigating a property's environmental history through methods like reviewing historical maps and documents, site visits, and sampling to identify any areas of concern from past contamination. 3) The process typically involves two phases - a initial non-intrusive investigation and then physical sampling if needed. Case studies from Clark, NJ involving soil vapor testing and Fairview, NJ regarding removal of a leaking oil tank illustrate this process.

1. RIDER UNIVERSITY
2015 SHADOWING EXPERIENCE
By: Norbert Iari
GEMS Department

2. PURPOSE
To shadow Mr. Randy S. Kertes PG, CPG, at Sadat
Associates Inc., on the “Due Diligence” (Kertes
2014) process; in order to gain experience in the
business application of environmental science.

3. Mr. Randy S. Kertes
Education:
University of Cincinnati, OH M.S., Geology, 1984
Rider University, Lawrenceville, NJ B.S, Geology
Now:
-Vice President of Science and Land Use at Sadat Associates
Inc.
-Mr. Kertes has over 27 years of professional experience in
the environmental consulting and land development fields.
-Manages a wide range of environmental cleanups and state
land use permits.
-In addition, he has provided testimony relating to
environmental remediation and minimization of adverse
impacts in both residential and commercial developments.

4. WHAT IS DUE DILIGENCE?
Business Aspect:
“… Making appropriate inquiries to determine
whether an organization’s existing or prospective
third parties are honest and can be reasonably
expected to refrain from corruption.”– weforum.org
(by PAC Initiative)
Environmental Aspect:
“Historical Investigation to the environmental
disposition of a property for the protection of the
purchaser or the seller.” – Mr. Randy Kertes

5. STEPS INCLUDE
Phase 1 (non-intrusive investigation):
-Historic maps and aerial photographs
-Adjacent property visits
-Site Visits
-Interviews
-Document Reviews
-Engineer's Opinion Report
Phase 2: (physical sampling)
-site investigation
-sampling and testing
-remedial investigation and action

6. PHASE 1
Non Intrusive Investigation:
Conclusion: With the evidence presented, does the
property have an area of concern?

7. PHASE II CASE STUDY I
SOIL VAPOR TESTING CLARK, NJ
This site is partially vacant and being utilized for an
automobile repair facility and a diner. However, the vacant
portion of the site was a former dry cleaner facility. Dry
cleaners (generally in the past) use chlorinated solvents as a
cleaning fluid. Chlorinated solvents are especially
problematic because they are more dense than water and
therefore sink. A big chain pharmacy has this site under
contract for redevelopment therefore, one of the areas of
concern is a former release of tetrachlorethylene (aka “perc”
of PCE). Sadat Associates, Inc. was contracted by the seller to
perform a soil gas survey for determining potential soil
remediation options and specific soil gas engineering controls
for the new structure.

11. PHASE II CASE STUDY II
FAIRVIEW, BERGEN COUNTY, NEW JERSEY
A 1,000 gallon storage tank, used for heating oil,
was removed by D.T. Allen Contracting Company.
The storage tank had approximately 1 dozen
corrosion holes which ranged from sizes of about
pinhole size to ¼ of an inch. 97.31 tons of
contaminated soil was then excavated from around
the former storage tank location. Soil samples were
taken and the ground water was investigated. The
results indicated that the high contaminant
concentrations were that of Benzene. The high
Benzene concentration was due to a former gas
station’s leaky storage tank nearby. The case was
never closed and DEP now orders the property
owner to conduct new sample testing.

Strata of concern
Samples were taken from the
“strata of concern”. The samples
were put into a glass jar and
sent to a laboratory in order to
confirm the identity of the
intrusive chemical.
No PID readings

18. CONCLUSION
As industries grow, so do environmental concerns. The “Due
Diligence Process” is a step by step process conducted by a
third party. The process abides by a legal and professional
system. In the environmental field, the due diligence process
is necessary, in order successfully protect the purchaser, or
seller, during real estate. This process not only raises
environmental concerns that can lead to clean ups that are
beneficial for the environment, but the process also helps
stimulate the economy. It sets the framework for putting
unused property back no the business of real estate, which
can eventually allow the economy to grow.
