AQUIFER TEST WELLS (15A NCAC 02C .0220)
These wells are used to inject uncontaminated fluid into an aquifer to determine aquifer hydraulic characteristics.
IN SITU REMEDIATION (15A NCAC 02C .02251 or TRACER WELLS (15A NCAC 02C .0229):
1) Passive Injection Systems - In -well delivery systems to diffuse injectants into the subsurface. Examples include
ORC socks, iSOC systems, and other gas infusion methods (Note: Injection Event Records (IER) do not need to be
submitted for replacement of each sock used in ORC systems).
2) Small -Scale Injection Operations — Injection wells located within a land surface area not to exceed 10,000
square feet for the purpose of soil or groundwater remediation or tracer tests. An individual permit shall be required
for test or treatment areas exceeding 10,000 square feet.
3) Pilot Tests - Preliminary studies conducted for the purpose of evaluating the technical feasibility of a
remediation strategy in order to develop a full scale remediation plan for future implementation, and where the
surface area of the injection zone wells is located within an area that does not exceed five percent of the land surface
above the known extent of groundwater contamination. An individual permit shall be required to conduct more
than one pilot test on any separate groundwater contaminant plume.
4) Air Injection Wells - Used to inject ambient air to enhance in -situ treatment of soil or groundwater.
5) In -Situ Thermal Wells (IST) — Used to `heat' contaminated groundwater to enhance remediation.

Assumptions
In generating this design proposal REGENESIS relied upon professional judgment and site specific information provided by
others. Using this information as input, we performed calculations based upon known chemical and geologic relationships
to generate an estimate of the mass of product and subsurface placement required to affect remediation of the site. The
attached design summary tables specify the assumptions used in preparation of this technical design. We request that
these modeling input assumptions be verified by your firm.
REGENESIS developed this Scope of Work in reliance upon the data and professional judgments provided by those whom
completed the earlier environmental site assessment(s). The fees and charges associated with the Scope of Work were
generated through REGENESIS' proprietary formulas and thus may not conform to billing guidelines, constraints or other
limits on fees. REGENESIS does not seek reimbursement directly from any government agency or any governmental
reimbursement fund (the "Government"). In any circumstance where REGENESIS may serve as a supplier or subcontractor
to an entity which seeks reimbursement from the Government for all or part of the services performed or products
provided by REGENESIS, it is the sole responsibility of the entity seeking reimbursement to ensure the Scope of Work and
associated charges are in compliance with and acceptable to the Government prior to submission. When serving as a
supplier or subcontractor to an entity which seeks reimbursement from the Government, REGENESIS does not knowingly
present or cause to be presented any claim for payment to the Government.
Closing
Please feel free to contact me if you need additional information or have any questions regarding our evaluation and/or
this correspondence (contact info listed above). Thank you for considering REGENESIS as part or your remedial solution for
this project.

PERSULF oX.
PersulfOx" Technical Description
PersulfOx is an In Situ Chemical Oxidation (ISCO) reagent that destroys
organic contaminants found in groundwater and soil through powerful, yet
controlled, chemical reactions. A sodium persulfate-based technology
(figure 1), PersulfOx employs a patented catalyst to enhance the oxidative
destruction of both hydrocarbons and chlorinated contaminants in the
subsurface.
Typically, sodium persulfate is activated with the addition of heat, chelated
metals, hydrogen peroxide, or base in order to generate sulfate radicals.
These activation processes are inherently complex, costly and can pose
additional health and safety risks. In comparison, PersulfOx is a relatively
safe and easy -to -use ISCO agent with a built-in catalyst which activates the
persulfate component, generating contaminant -destroying free radicals
without the need for the addition of a separate activator. The equation
below shows the net complete oxidation of toluene, a constituent of
gasoline, by PersulfOx:
0'+ 18 Nat 208 + 14 H2O 7 CO2 + SB NaWi
