1.0 Introduction

1.1 Objective

This New Technology Cleanup Plan (NTCP) has been prepared by ARM Environmental
Services, Inc. (ARM) for Sadler’s Country Corner in response to a request from the North
Carolina Department of Environmental Quality (NC DEQ) in the Notice of Regulatory
Requirements (NORR) correspondence dated May 15, 2023.

Upon the routine submittal of the semi-annual Groundwater Monitoring Report and The
Corrective Action Performance Report detailing the former mobile soil vapor extraction
active remediation system at the site in December 2021, NC DEQ subsequently responded
with an NORR letter for requirements to determine if enhanced bioremediation, i.e., the
injection of oxygen reducing compounds or microbes would be a viable option at this site.
This information was requested to be provided in the form of a Corrective Action Feasibility
Study (CAFS). ARM submitted a pre-approval request for costs for a Pilot Study Injection
including preparation of a Notice of Intent for injection, drilling of two borings for the Pilot
Study, chemical oxidant injection in these borings, preparation of the CAFS, and associated
costs. An extension was requested and approved for the Pilot Study and submittal of the
CAFS. In June 2022, the Notification of Intent (NOI) to construct or operate injection wells
was submitted and the Pilot Study injection was performed in August 2022. Due to the
results of the November 2022 Groundwater Monitoring event indicating apparent
effectiveness of the pilot study injection in the area of influence of the most concentrated
dissolved constituent well, MW-2, ARM recommended performance of a full oxidant injection
strategy for the site coupled with continued sampling to monitor the effectiveness of the
remedial strategy. Also in December 2022, ARM submitted the CAFS. Once a review of the
CAFS was complete by NC DEQ, the May 15, 2023 NORR correspondence indicated the
NC DEQ’s agreement of the proposed corrective action injection.

The objective of the proposed corrective action is to achieve dissolved contaminate
concentrations that are below the 15A NCAC 02L.0202 Groundwater Quality Standard in a
timely manner. Ultimately, the goal is to reach “Conditional No Further Action” status for the
release at the site.

1.2 Site Description

The Sadler’s Country Corner site is located at 4262 Highway 27 in Alexis, North Carolina. A
topographic Site Location Map is included as Figure 1. The Sadler’s Country Corner site
was operated as a retail gasoline station and convenience store by Mr. Ron Sadler and
subsequently has been operated by others. Currently the property is owned by Mr. Ron
Sadler under the entity, Sadlers Country Corner, LLC.

The site is located in an area of mixed commercial and single-family residential
development. The site is comprised of approximately 0.71 acres and is occupied by an
approximate 3,360-square foot concrete block convenience store building. Ownership and
tax map information for the subject property and adjoining properties is included in Appendix
A.

1.3 Site Remediation History

According to historical documentation prior to the involvement of ARM at the site, an onsite
remediation system was proposed in a Corrective Action Plan by Allied Environmental
Services, PLLC (AES) in May 2004. The remediation system to address the contaminants
from the incident consisted of a soil vapor extraction / air sparge (SVE/AS) system. The
SVE system was installed and placed into operation by AES in May 2006. The AS system
was installed and placed into operation by AES in August 2007. It should be noted that
ARM did not design, approve, procure, or install the SVE/AS system at the site.

The responsible party for the incident, Ron Sadler, selected ARM to take over work on the
site in the last quarter of 2010. ARM reviewed the file at the Regional DENR office and
began work at the site. Mr. Sadler stated that the remediation system always overheated
and therefore was placed on a timer so that the SVE blower would run 12-hours on and 12-
hours off. Upon inspection of the remediation system, it was determined that the SVE
blower was not functioning at all. ARM immediately submitted a Task Authorization (TA)
request in October 2010 for replacement of the blower in order to make the system
functional. Upon approval of the TA by DENR (TA #23108-51) ARM replaced the blower.
While replacing the blower additional damage to the system was identified. A vacuum relief
valve, and associated piping, screen, fittings, etc. had also failed. Task Authorization
#23108-52 was requested in January 2011 and approved for the additional repairs. The
repairs were completed and the system was again functional.

Sadler’s Country Corner
New Technology Cleanup Plan
July 10, 2023

In July 2011 the system again began to have difficulty operating. It was determined that
the 3-phase contactor in the control panel was failing. Another TA, TA #23108-54, was
requested and approved for the repair. The contactor and associated wiring were replaced
and the system was put back into service.

Beginning in November 2012, free-phase product was identified at a thickness of 3.35 feet
in MW-2 at the site. MW-2 is located approximately 20 feet down gradient to the west of
the 3,000-gallon premium Underground Storage Tank (UST). No free-phase product had
been detected prior to the November 2012 gauging/sampling event at the site. On
February 1, 2013, the 3,000-gallon premium gasoline UST at the site failed the tank
tightness test. The other tanks at the site as well as the product lines passed the tightness
tests. A day prior to the tightness test, Mr. Sadler identified a potential loss of fuel from the
premium tank based on inventory reconciliation. The contents of the tank were immediately
pumped out and the tank was cleaned. A liner was installed in the premium gas tank. The
tank passed tightness testing subsequent to the lining installation and was placed back into
service. A Site Base Map with the USTs, monitoring well and recovery well locations is
included as Figure 2.

In response to the occurrence of free-phase product at the site, DENR requested that a
System Enhancement Report be completed. The report was requested in order to
determine the best course of action to remove the contaminants from the site. ARM
completed the requested System Enhancement Report on behalf of Mr. Sadler in July
2014. An extensive analysis and comparison between enhancing the existing SVE/AS
system, and installation of recovery wells and completion of additional MMPE events was
conducted by ARM and was reviewed, agreed with, and approved of by Dynamic
Engineering Solutions, PC (DES) a professional engineering company. DES is
experienced in soil and groundwater remediation system design and installation.

The report included an evaluation of the flow, pressure, and air monitoring data collected
from the onsite SVE/AS system, dissolved-phase groundwater contaminant trends, and
pollutant mass removal calculations and product thickness data from the onsite MMPE
events. The conclusion of the System Enhancement Report indicated that installing
recovery wells and continuing MMPE events would likely be the most cost-effective and
time-efficient method to mitigate the additional contaminant mass located on the property in
the area of MW-2 and MW-3. Because the recovery well / MMPE method will likely be the
most time-effective method, it is considered the most protective of the nearby water supply
well receptors.

In the System Enhancement Report, ARM recommended the installation of three (3) 4”
diameter recovery wells in the immediate vicinity of the encountered free-phase product in
order to increase recovery and maintain a sufficient radius of influence during the MMPE
events. However, only one recovery well was approved by the DEQ. A Task Authorization,
TA #23108-62, was submitted and approved for the installation of a single recovery well.
The recovery well, designated RW-1, was installed in the immediate vicinity and down
gradient of MW-2 in November 2014.

At the request of DENR, Mobile Multi-Phase Extraction (MMPE) events were then started
on a roughly bi-monthly basis at the site in order to begin the removal of the free-phase
product from the vicinity of MW-2. In October 2014, the SVE blower began to shut down
randomly. The issue continued for several weeks until the system was only operational a
few hours per day and the blower did not appear to be operating to manufacturer’s
specifications. Task Authorization #23108-63 was submitted and approved for blower
replacement. The blower was installed in February 2015. The replacement blower was
found to be only running for a few hours, then turning itself off. A system technician was
hired to evaluate the system. The replacement blower was removed and bench tested and
found to be fully operational within manufacturer’s specifications. Then the electrical
components of the system were evaluated. It was determined that one of the legs of the
electrical overload system was damaged. The replacement parts were installed and the
blower was reinstalled. The system was again restarted in May 2015 and was fully
operational.

Mr. Sadler notified ARM in late August of 2015 that again the system had begun to shut off
several times per day. The system had progressively gotten worse and essentially became
non-functional. Additionally, the original remediation system, the aforementioned AS / SVE
system, was designed and installed based on lower level dissolved-phase concentrations of
chemicals of concern from the original release of the incident. The system and piping layout
was not adequate to remediate, in a timely and cost-effective manner, the free-phase
product that appeared at the site when the 3,000-gallon premium UST failed in 2012 / 2013.
The former remediation system was taken completely off-line and was dismantled.

New Treatment System Installation and Operation

As requested by NC DEQ, a mobile soil vapor extraction (SVE) system was rented and
installed in 2017. The rental system was requested by DEQ in order to remove the free-
phase product located east of the underground storage tank basin, as identified in
monitoring well MW-2 and recovery wells RW-1 and RW-2. A rotary claw compressor SVE
system in an enclosed trailer was installed to extract petroleum vapors from monitoring well
MW-2 and recovery wells RW-1 and RW-2. The system installation was completed and the
system was started at the beginning of October 2017.

The SVE blower was found to be non-functional at the end of the first half of 2020. ARM
mobilized to the site in August 2020 to remove and test the blower motor, which was found
to be faulty. A new blower motor was procured and installed on September 11, 2020. The
SVE system was brought back into full operation. Full system maintenance was also
completed on the system in September 2020.

During the February 2021 system check, the system was found to be shut down. Upon
clearing out the tripped motor starter for the blower, the blower was restarted and a very
loud noise occurred. Upon collaboration with SSI and troubleshooting several external
blower components, it was decided that the noise was an internal rotary claw component
and the system had to be shut-off. SSI sent a local repair service by on March 3, 2021 to
install another blower and restart the system.

Based on the fact that free-phase product on-site had decreased significantly in overall
thickness to no detections in MW-2 and recovery wells RW-1 and RW-2 since the
installation of the mobile system in late 2017, a letter was received from NC DEQ, dated
Aug 18, 2021 to de-activate system. Following the system Operations and Maintenance on
August 19, 2021 and per the above-mentioned letter, ARM de-activated the system. ARM
subsequently called the rental trailer treatment system off rental and told the rental
company to come pick it up and remove from the site. The trailer unit was transported off
the site by the rental company on October 27, 2021. In concurrence with the NC DEQ’s
decision to de-activate the system and remove it from the site, ARM recommended no
additional active treatment measures at that time and continuation of monitoring of the site
through natural attenuation.

2.0 Geology / Hydrogeology

2.1 Regional

Geology

The Geologic Map of North Carolina (1985) indicates that the site is located in the Inner
Piedmont Belt of the Piedmont Physiographic Province. According to the geologic map, the
project property is likely underlain by metamorphosed quartz diorite, which is a rock similar,
but slightly less siliceous than granite. The Inner Piedmont Belt also contains other
metamorphic assemblages. Typically, crystalline bedrock of the Piedmont weathers in the
shallow subsurface to a variable thickness of unconsolidated, residual soil material, which
lies above the bedrock and often retains some structure of the bedrock, in which case the
term saprolite is often applied. In some areas or depth zones, weathering results in a
structureless soil termed residuum, although residuum or residual soil can also refer to the
entire unconsolidated zone above the bedrock. The base of the saprolite often grades into
bedrock through a zone known as partially weathered rock (PWR), which contains rock
fragments and more consolidated material. Generally, a gradual downward lithologic and
textural change occurs from residuum, to saprolite, to PWR, to bedrock. Bedrock depth
varies from ground surface at outcrops to depths of 70 or more feet in areas of readily
weathered material. In some stream valleys deposits of alluvium have resulted from erosion
and transport of soils from uphill locations.

Hydrogeology

Saprolite Aquifer

Groundwater in the Piedmont is often first encountered as a water table in pores within the
residual soils and alluvium. On a general regional basis, permeability may be relatively high
in alluvium or saprolite, if sandy material is present. However, permeability is generally
relatively low in the residuum, with somewhat greater permeability found in the saprolite
and PWR due to relict rock texture and variable susceptibility to weathering exhibited by
different minerals in the rock. Groundwater becomes increasingly confined to fractures and
other structural features as rock integrity increases at depth. The shallow aquifer
occurrence varies in depth from ground surface at springs, creeks, and rivers to as deep as
50 feet or more beneath upland surfaces in some parts of the Piedmont. Water in the
alluvium or unconsolidated residual material usually behaves as an unconfined, or water
table, aquifer and will yield water at the elevation where water is encountered. Saprolite or
alluvial groundwater flow is usually in rough concurrence with local topographic conditions
and is toward local drainage features. For sites in the Piedmont, when gradient conditions
are discussed, upgradient sites are in locations which could, based on topographic or flow
analysis, have shallow groundwater migration from them toward the project site.
Sidegradient sites are nearby sites with equivalent land surface or water table elevation to
the project site, which would be unlikely to have groundwater movement generally parallel
to the project site, and downgradient sites are nearby sites, which likely receive
groundwater migration from beneath the project property.

Bedrock Aquifer

The bedrock fractures or other planar features generally constitute the bedrock aquifer, with
the surrounding rock material being effectively impermeable. Along with fractures, the
contacts between rock bodies probably constitute areas of significant groundwater
occurrence in the bedrock. The surrounding material and overlying residuum tend to make
the bedrock aquifer a semi-confined aquifer; that is, the overlying water and soil weight
normally results in pressure that causes water in a borehole which intersects a fracture or
other feature to rise above the elevation of the fracture or feature. Such features may not
occur on predicable trends, at the same elevations, or even be present or directly connected
in separate boreholes. In areas adjacent to creeks, the bedrock groundwater generally
discharges to the residuum or alluvium and then into the surface water. In areas away from
surface water drainages, the bedrock aquifer is generally recharged by downward infiltration
of water from the shallow aquifer at locations where fractures intersect the bedrock surface.

2.2 Site Specific

At the site, the shallow subsurface appears to be various combinations of silt, clay and
sand with a tan sandy clay being fairly continuous in the zone from approximately 1 foot to
4 feet below ground surface (bgs). A red silty clay occurs from approximately 4 ft bgs to
approximately 32 ft bgs. A darker red silty clay is present from approximately 32 ft bgs to
approximately 40 ft bgs.

3.0 Proposed Corrective Action Methodology

3.1 Overview

Several corrective action methodologies and technologies were considered to remediate the
site contaminants during an initial remediation alternatives screening process. Source
excavation, AFVR, air sparging with soil vapor extraction, injection of powdered granular
activated carbon, and in-situ chemical oxidation were all considered for the site. The
potential corrective action technologies and methodologies and their applicability to the site
based on a review of the attributes and logistics of installation and operation, technical
likelihood of success, and economic concerns were discussed. The prior removal of free-
phase product at the site aids greatly in the remediation of the remaining dissolved phase
contaminants above NC 2L concentrations. In-situ chemical oxidation has been selected as
the corrective action method based on the above factors.

3.2 Injection of Reagents

Based on the necessity to reduce the concentrations of dissolved-phase contaminants in the
source area onsite associated with the release in a timely manner, ARM proposes the
injection of in-situ chemical oxidant reagents. Because the free-phase product has been
removed from the site, the use of such materials can be effective as a ‘polishing’ technology.
This methodology will incorporate sodium persulfate injections with a chelated iron catalyst.
The sodium persulfate most likely utilized will be the Klosur® SP product produced by
Evonik Active Oxygens, LLC (formerly FMC Environmental Solutions / PeroxyChem). It is
proposed that the sodium persulfate will be mixed at a concentration of 25-32% by weight. A
25% sodium hydroxide (NaOH) solution is proposed to be used as an alkaline activator. The
alkaline activation method is preferred in lieu of the chelated Iron catalyst as it is considered
advantageous to the injection design and logistics of the site.

Sadler’s Country Corner
New Technology Cleanup Plan
July 10, 2023

Page 9
The volume of injectate employed in the system will be based on an evaluation of
effectiveness as corrective action progresses. It is proposed that approximately 300 gallons
of the chemical oxidant and catalyst mixture will be injected into each well point during each
injection event, if possible. A greater volume may be injected if the formation will accept it.
Detailed descriptions and fact sheets for each of the above listed products are included in
Appendix B.

Additionally, if free-phase product globules are found and remain difficult to desorb from the
soil matrices, surfactants or co-solvents may be considered. These remedial compounds
can act to reduce sorption effects and release significantly more product material from the
subsurface soil matrix, thus, the recoverable amounts of contaminants can be effectively
increased.

In the event these compounds are considered due to inadequate injection performance,
concurrence from the NC DEQ Incident Manager will be sought regarding specific product
and methodology changes prior to implementation.

3.3 Reagent Source Injection Well Points

Existing recovery wells RW-1 and RW-2 will be utilized for the oxidant injection. The Well
Construction Records for these wells are included in Appendix C. Additional injection well
points will need to be completed as a part of the reagent injection remediation effort. Four
temporary injection wells (TIWs) are proposed near the source area, and will initially be
incorporated into the reagent injection corrective action methodology. Additional injection
well points may be subsequently installed based on evaluation of effectiveness as the
corrective action progresses. Monitoring wells will be protected and will not be used for
reagent source injection. The TIWs will be completed with multi-port retractable injection
tooling with direct push methodologies. A temporary injection well schematic is included in
Appendix D. The injectate will be pumped under pressure through the down hole direct push
tooling string and injection tooling, and through the 4” PVC recovery well screens, utilizing a
pneumatic double diaphragm pump system.

The target depth of the injectate emplacement will be in the twenty-five to forty feet bgs zone
in the vicinity of the most concentrated dissolved constituent well, MW-2. The volume of the
injectate employed in the system will be based on evaluation of effectiveness as corrective
action progresses. An Underground Injection Control Permit Application will be provided as
needed.

3.4 Technical Support

Evonik Active Oxygens, LLC (formerly FMC Environmental Solutions / PeroxyChem, Inc.)
offers a preponderance of technical support and site-specific recommendations for
implementation of their chemicals. They recommend that their technical office be provided
with information concerning the site hydrogeologic framework and the dynamics of the
contaminant plume so that a plan of implementation can be formulated based on their
expertise with the chemical system. Additionally, they often recommend that a pilot system
be implemented to provide an indication of the overall effectiveness of the treatment prior to
any long-term agreement for application. In this case, the pilot study has been performed.
Prior to implementation of the reagent source injection, technical assistance from Evonik
Active Oxygens will most likely be requested. As such, the proposed implementation of
reagent injection of this corrective action plan is subject to change. However, since the pilot
study performed has indicated effectiveness, the proposed product will most likely be the
product utilized. The NC DEQ will be notified of any change in this regard by addendum
prior to any implementation.

4.0 Evaluation of Corrective Action Effectiveness

In order to evaluate the performance of the in-situ chemical oxidation, ARM proposes to
continue semi-annual groundwater monitoring of the well network at the site.

5.0 Regulatory/Technical Protocol and Quality Assurance

An Underground Injection Control Permit will be acquired from the NC DEQ for the in-situ
chemical oxidant injections.

Sadler’s Country Corner
New Technology Cleanup Plan
July 10, 2023

Page 11
ARM will conduct all sampling using protocol designed to minimize the potential for bias. At
a minimum, the samples will be protected from cross-contamination using the following
quality assurance/quality control procedures:

 Pre-cleaned or new disposable sampling equipment will be used to collect
samples;
 Any multiple-use equipment will be cleaned between locations and tasks by a
tap water and Alconox® wash, tap water rinse, and de-ionized water rinse.
 Disposable sample gloves will be worn by sampling personnel during
monitoring and sampling activities and will be changed between locations and
tasks.
 The samples will be collected in certified-precleaned sample containers with
appropriate preservative;

Each sample will be placed in labeled containers, packed in ice, and hand delivered to North
Carolina-accredited Pace Analytical in Cayce, South Carolina (Accreditation No. 329).
Chain-of-custody documentation will be maintained from the time of sample collection
through analysis. Each of the samples will be analyzed in accordance with the analytical
plan.

6.0 Site Restoration

Upon notification by NC DEQ that the corrective action goals have been achieved, the
corrective action system including any injection, recovery and monitoring wells, will be
removed from the site in accordance with the NC DEQ requirements. All injection, recovery
and monitoring wells will be abandoned in accordance with North Carolina Well Standards
and Regulations by a North Carolina certified well driller. Additionally, the NC DEQ will be
notified of final disposal of any remaining contaminated soil and/or groundwater.

Klozur® SP Application Guidelines
Klozur® SP is a high purity environmental grade sodium persulfate that has been successfully used to remediate
contaminants of concern (COC) at environmental sites around the world. Klozur persulfate can be activated using
PeroxyChem’s patented technologies1 to form powerful oxidative and reductive radicals that aggressively treat the
targeted contaminants. PeroxyChem’s persulfate activation technology is well established having been successfully
applied in thousands of field applications and scientifically validated in hundreds of independent peer-reviewed journal
articles and conference presentations.
Klozur SP is part of PeroxyChem’s Klozur Portfolio which also includes Klozur One, Klozur KP, and Klozur CR. Klozur
products are typically applied using an injection, soil mixing, or backfill strategies to establish contact between the
activated persulfate and the contaminants of concern. This document will provide general application guidelines for
Klozur SP. For more information on Klozur SP or other products in PeroxyChem’s Klozur Portfolio, please visit
klozur.com.
FIELD APPLICATIONS
PeroxyChem recommends activation of Klozur SP with alkaline, iron-chelate, heat, and hydrogen peroxide activation
chemistries. For more information on each activation chemistry, please visit www.klozur.com.
PeroxyChem recommends batching and storing the activation chemistry and Klozur SP separately. It is also
recommended that all the wetted components of the injection system be chemically compatible with all chemistries.
The reagents can then be combined via in-line mixing prior to being injected or pulsed into the subsurface separately.
In-line mixing requires an injection skid capable of blending the two reagents just prior to injection at the wellhead. A
pulsed strategy involves injecting one solution at a time and allowing them to mix in situ. This can require oscillating
between the reagent solutions frequently. Typically, this would involve the injection of 400 gallons (gal), or
approximately 1,500 liters (L), of Klozur SP followed by 100 to 200 gal (approximately 400 to 800 L) of activator
solution.
Batching Klozur SP
When batching any Klozur product, it is important to ensure that the tank, water, mixing equipment and any other parts
that will contact the reagent solution are clean and devoid of impurities that might react with the oxidant. Klozur SP
should be batched in systems where all wetted parts or parts that could become wetted are chemically compatible
with Klozur SP. Please refer to PeroxyChem’s Technical Bulletin: Corrosion and Material Compatibility with Klozur
Persulfate, which can be found at peroxychem.com/remediation, for a list of chemically compatible materials. A
chemically compatible secondary containment is also recommended beneath the batching system.
Klozur SP is highly water soluble over normal temperatures providing a great deal of flexibility in the field in terms of
batch concentration. PeroxyChem recommends that Klozur SP be injected in a range from 50 to 250 grams per liter
(g/L). To achieve these concentrations, it is recommended that Klozur SP be batched at a concentration less than
the theoretical solubility (Table 1).

Product Application Guide
[e-mail] | 1.866.860.4760 | peroxychem.com/remediation
It is recommended that batches of Klozur SP be injected or applied within
eight hours of the dilution in water and that Klozur SP, batched, or otherwise
stored, not be left unsecured or unsupervised. Solutions stored longer than
eight hours are expected to be stable; however, the Klozur SP will slowly
degrade and is expected to generate acid. If impurities are present or at
elevated temperatures, the rate of reaction will increase.
Klozur SP can be mixed using a variety of methods. The most common
methods are mechanical and hydraulic mixers. Most mechanical mixers are
mounted to the top of the batch tank and involve a motor, shaft and propeller
that mixes the solution. Hydraulic mixers usually include some form of
recirculating the batch solution. The time required to dissolve Klozur SP will
increase with increasing concentrations. Generally, with an adequate mixing
system, Klozur SP should be completely dissolved within 5 to 20 minutes.
Injection Equipment
Klozur SP can be injected using a single chemically compatible pump. Common pumps used include centrifugal and
double diaphragm pumps sized according to the anticipated injection rate and down gradient pressure. Most double
diaphragm pumps have the secondary benefit of creating inlet negative pressure that can be used to pull Klozur SP
from the batch tank. The inlet is usually placed at the base of the tank with a foot valve. This removes the need for a
gravity feed coming from the bottom of the batch tank which is necessary for most centrifugal pumps.
Depending on the injection objectives, other common components that may be necessary in an injection system
include flow meters, pressure gauges, pressure relief valves, temperature gauges, valves to open and close portions
of the system (i.e. ball valves or equivalent), and valves to help moderate injection rates (i.e. gate valves or equivalent).
If injecting into multiple locations simultaneously, multiple injection lines can be split off down gradient of the injection
pump with each line typically having its own set of valves, gauges, and flow meters. All components of the injection
system must be chemically compatible with Klozur SP and the activator chemistry.
Establishing Contact
Effective treatment of site contaminants is achieved by establishing sufficient contact between activated Klozur SP
and the contaminants. To help estimate the quantity of Klozur SP and activator needed, please contact your
PeroxyChem Technical Representative or email us at [e-mail].
The method used to establish sufficient contact between Klozur SP and the COCs is a critical aspect of the remedial
application with injection and soil mixing being the most common strategies used for establishing contact.
Injection Strategies
Injection strategies introduce the previously dissolved (batched) Klozur SP solution into the subsurface through
chemically compatible wells or rods. The wells or rods are typically solid (blank) until reaching the intended depth
where the reagents can flow through screens and out into the targeted interval of the subsurface. The reagents are
then distributed into the subsurface for a certain radius of influence (ROI) depending upon the site characteristics and
injection volume. At most sites, Klozur SP can be expected to persist for weeks to months which may be sufficient
time for it to migrate with groundwater flow after injection.

Common types of injection strategies include direct injection and recirculation.
Direct Injection
With a direct injection strategy, Klozur SP is injected into the subsurface and the volume of the injection is used to
push Klozur SP out a distance from the injection point to contact contamination in soil, non-aqueous phase liquid, and
groundwater. There is no extraction with a direct injection strategy. The injection is typically under a pressure lower
than the fracture pressure of the soils at the top of the injection interval. The volume of reagents injected can be critical
in terms of the distance from each injection point the reagents are distributed. This distance is commonly referred to
as the radius of influence, or ROI.
There are typically three ROIs:
• Design ROI. The design ROI is the radius intended to be treated by each injection point. This can include the
injection ROI, as well as additional distribution of the reagent due to diffusion and advection with groundwater
flow after the injection event. Injection point spacing is often set so that the design ROIs overlap, typically by
15 to 20 percent, which minimizes untreated areas and results in additional treatment of soils furthest from
the injection points.
• Injection ROI. The injection ROI is a design parameter estimating the distance the injection volume will
distribute the reagents from the injection point. This is typically estimated by equating the injection volume to
the effective pore volume or pore volume at different distances from an injection point. For example, assuming
1,500 gallon injection volume and an effective pore volume of 0.15, the injection ROI would be R = sq root
(1,500 gal/(π * h (ft) * 7.48 gal/ft3 * 0.15)).
• Observed ROI. This is the actual ROI from an injection point confirmed in field optimization studies or field
pilot tests. The observed ROI may vary vertically with different soil types and preferential flow paths even from
the same injection point.
The injection volume is typically set so that the injection ROI is less than or equal to the design ROI. If less than the
design ROI, it is typically assumed that the Klozur SP solution will be distributed either by natural groundwater flow
(advection) or diffusion.
Recirculation
In a recirculation strategy, groundwater is extracted from one set of wells, amended with Klozur SP, and then reinjected
into another set of injection wells. A recirculation strategy is commonly used to help control or limit the distribution of
the reagent solution. Extraction wells typically out number injection wells since reagents injected under pressure
typically flow at a higher rate than groundwater can be extracted.
Constructed Injection Wells
Constructed wells should be made with materials compatible with Klozur SP including stainless steel, polyvinyl
chloride (PVC), or chlorinated polyvinyl chloride (cPVC). The wells are typically constructed with a screen interval,
sand pack interval, a bentonite seal directly above the sand pack, and lastly a bentonite or grout slurry to surface. The
sand pack interval that is typically slightly larger than the screen interval to prevent the bentonite seal from impacting
the screen. It is generally best to align the sand pack interval with the targeted contaminant interval in most applications
where Klozur SP is injected under pressure and the sand pack is more permeable than the native soils. Constructed

Product Application Guide
[e-mail] | 1.866.860.4760 | peroxychem.com/remediation
wells can also be made using “pre-pack” screen, sand pack, and bentonite seals. For these wells, the screen and
sand pack intervals are typically the same.
Direct Push Technology Injection Points
Injecting Klozur SP through direction push technology (DPT) points is also possible. Since carbon steel is the common
material for DPT rods, most practitioners prefer to use alkaline activated persulfate to help minimize possible corrosion.
Other steps to mitigate corrosion that are commonly taken include taping or otherwise protecting the rod threads with
materials compatible with Klozur SP, and rinsing the rods after use and prior to storage. The rinse solution often
includes a pH buffer, such as sodium bicarbonate and a reactant such as an alcohol or sodium ascorbate.
Other activation methods can be used with DTP systems utilizing stainless steel or other chemically compatible
materials. PeroxyChem recommends coordinating with your DPT contractor to make sure they are using a chemically
compatible system to inject Klozur SP.
Soil Mixing
Soil mixing is the second common method of establishing contact between Klozur SP and contamination in the
subsurface. A soil mixing strategy typically involves the mechanical agitation of subsurface soils blending in both
Klozur SP and the necessary activator reagents. The mechanical agitation breaks apart the natural soil structure and
helps to establish contact between activated Klozur persulfate and the contamination found in the soils. Good contact
is key for successful remediation and soil mixing can be particularly useful in treating source zones and lower
permeable soils such as silts or clays.
Soil mixing has been used:
• As the primary method of treatment in source areas
• To treat residual contamination after excavation as a secondary method of treatment
• In combination with in situ stabilization (ISS) and other technologies
Soil mixing equipment often includes equipment containing carbon steel. Klozur SP, by itself, is corrosive to carbon
steel. Most practitioners prefer alkaline activated persulfate for soil mixing as it helps protect the carbon steel mixing
equipment. If interested in a soil mixing application, please contact your PeroxyChem Technical Representative or
email [e-mail] to discuss how to decrease the potential corrosion of the mixing equipment.
For more information, please refer to the Klozur Persulfate Soil Mixing Recommendations and Applications Guidelines
document, which can be found at peroxychem.com/remediation.
OPTIMIZATION STUDIES: BENCH AND PILOT SCALE TESTS
Projects often include a series of tests to help develop and confirm a variety of design parameters and assumptions
prior to the full-scale application of Klozur SP. PeroxyChem recommends performing bench scale tests to estimate
the non-target demand associated with the soil and, if desired, to confirm the treatment effectiveness of different
concentrations of Klozur SP with contaminated site soils and groundwater. The non-target demand test is a critical
design element for Klozur SP. PeroxyChem refers to our non-target demand, or soil oxidant demand (SOD), test as
the Klozur Demand Test (KDT). PeroxyChem has a full-service treatability laboratory to conduct bench scale studies
using Klozur SP. More information on these lab tests is available from your PeroxyChem Technical Representative or
by emailing [e-mail].

Product Application Guide
[e-mail] | 1.866.860.4760 | peroxychem.com/remediation
Field optimization studies or field pilot tests can be used to further assess the application of Klozur SP prior to a full-
scale application. In addition to confirming treatment effectiveness, common objectives of these field evaluations
include assessing injection pressures, flow rates, reagent distribution, and using the observed ROI to confirm the
assumptions made in determining both the design and injection ROI.
STORAGE AND HANDLING
Klozur SP is a UN Class 5.1 oxidizer. It should be stored in a secure, cool and dry location. The temperature of Klozur
SP should not exceed 45°C (113°F). PeroxyChem does not recommend storing Klozur SP in field conditions for

The Solution to Klozur® SP Solutions

This edition of Peroxygen Talk has the scoop on Klozur® SP solutions. Klozur SP is delivered as a white,
crystalline material in bags, drums or super sacks. In order to safely and successfully prepare persulfate
solutions for injection, it is important to understand the physical and chemical properties of Klozur SP.
Solution physio-chemical properties
1. Key Concentration Equations
Definition of wt%:
(1) wt% = wt of sodium persulfate / wt of solution x 100 = wt of sodium persulfate / (wt of sodium persulfate + wt of
water) x 100
Example: 20 wt% means 20 lbs of sodium persulfate per 100 lbs of solution
Conversion of wt% to g/L:
(2) g/L = 0.1049 * wt% * wt% + 9.1501 * wt% + 3.1347
Conversion of wt% to lb/gal:
(3) lb / gal = 0.0083 * g/L
2. Solubility
Klozur SP is a highly soluble salt that is easy to dissolve. Table 1 shows the maximum solubility of Klozur solutions
as a function of temperature:
Temperature Maximum Solubility
in wt%
~ 0 °C (32 °F) 37
25 °C (77 °F) 42
50 °C (122 °F) 46
Table 1: Solubility as a function of temperature
3. Density
The density of Klozur SP solutions is a function of persulfate concentration and can be determined by the following
equation:
Density (g/mL) = 6x10-5 * wt% * wt% + 0.0061 * wt% + 0.9999

Table 2 lists the density of Klozur SP solutions for several concentrations.
Concentration (wt %) Density (g / mL)
10 1.067
20 1.146
30 1.237
40 1.340
Table 2: Density as a function of concentration
The change in solution density as a function of concentration may have practical implications when preparing a
batch of Klozur SP solution. As an example, Table 3 displays the effect on solution volume as a function of
concentration when batching Klozur SP into 500 gallons of water.

Table 3: Solution volume as a function of concentration for an initial 500 gallons of water

As a result, adequate tank headspace needs to be assured for safety, especially when formulating higher sodium
persulfate concentration solutions.
4. Viscosity
Klozur SP solutions have low viscosities and flow like typical salt solutions. Table 4 shows the viscosity at room
temperature as a function of solution concentration.

Persulfate Aqueous Solution Decomposition
If stored and handled properly, Klozur SP as delivered has a shelf life in excess of one year. It is not
recommended storing bulk Klozur SP in direct sunlight or under tarps, especially in hot locations, such as the
southwestern US during the summer. This may lead to excessive decomposition. However, once in solution,
persulfate will auto-catalytically decompose. The rate of decomposition depends on several factors, including:
persulfate concentration, temperature, pH and the presence of an activator.
At dilute concentrations, such as encountered typically for in situ groundwater concentrations which range
from 5 – 50 g / L, the decomposition rate is relatively slow. As a result, persulfate may persist in the subsurface for
weeks to months, depending on the soil oxidant demand for the site. However, the decomposition rate can
significantly increase at concentrations ranging from 10 – 40 wt%, which are typical of injection concentrations.
The rate of decomposition for Klozur SP solutions will be the topic of a forthcoming Peroxygen Talk. In general, for
concentration between 10 – 30 wt% there is sufficient stability in the persulfate solution to allow batching of a day
tank without significant loss of persulfate (< 1%). It is highly recommended that the Klozur solution be utilized the
day of formulation, especially if the persulfate activators are added to the batch tank.
The by-product of persulfate decomposition is HSO4-. As a result, unless alkaline activation (see January
2006 Peroxygen Talk for discussion on activation chemistries) is used, the pH of a persulfate solution will decrease,
and may reach a pH as low as 1.9. As a result, low pH corrosion is a potential when working with persulfate
solutions. Corrosion and general materials compatibility and handling concerns will be the topic of an upcoming
Peroxygen Talk.
Injection Design with Klozur SP Solutions
One advantage of using Klozur SP over other oxidants such potassium permanganate is that solutions
concentrations up to 40 wt% can be formulated. This provides a high degree of freedom in designing an injection
plan. One frequently asked question regarding Klozur solutions is: What persulfate concentration should I use for
my site? The answer is that it is entirely dependent on how many pore volumes you wish to inject.

[e-mail] | 1.866.860.4760 | peroxychem.com/remediation

Peroxygen Talk

As an example to illustrate:
The injection plan calls for ten injection wells. The site has the following characteristics:
Radius of influence 10 feet
Soil porosity 30%
Total groundwater 281,250 gallons (28,125 gallons per well)
Calculations based on contaminant type and loading, verified by subsequent treatability testing, indicate:
Target Klozur groundwater concentration 25 g / L
Total Klozur demand 59,000 lbs (5,900 per well)
Maximum volume in batch tank 900 gal
Table 5 illustrates the formulation recipe and the volume of Klozur SP solution that will be injected as a percentage
of total pore volume.

40 4,033 725.3 14.6 5
Table 5: The % pore volume to be injected as a function of solution concentration.
As expected, as the Klozur SP solution concentration decreases, more water needs to be injected into the
formation to reach the target in situ persulfate concentration, resulting in a greater percentage pore volume being
displaced.
The high solubility of Klozur SP gives you the flexibility in tailoring the injection volume to your needs. If
you desire low pore volume turnover, then you can batch higher concentration solutions. If high pore volume
turnover is desired, then lower concentration persulfate solutions can be utilized. Please contact the Environmental
Solutions Team for support in oxidant calculations and chemical supply needs.

The Safe Use of Klozur® Persulfate Activators

Activators are used with Klozur Persulfate to convert the persulfate anion, a strong but kinetically slow
oxidant, into the sulfate radical, a much stronger and kinetically faster oxidative species capable of destroying a
wide range of organic contaminants. PeroxyChem is the owner or exclusive licensee of several patented methods
to activate persulfate: heat, high pH, metals and chelated metals, hydrogen peroxide and zero valent iron (ZVI).
The choice of activator system is dependent on several criteria, including the type of contaminants targeted, the
application method, site hydrogeology and lithology, and other site conditions such as the presence of structures
and underground utilities. Contact PeroxyChem and we can provide technical support for your selection of the
activator chemistry for your project. Additional information can be found at peroxychem.com/remediation. The
subject of this month’s Peroxygen Talk is the safe use of these Klozur Persulfate activation chemistries.

High pH Activation

High pH activation currently represents the most favored method for activation in the field. High pH –
activated persulfate has been demonstrated effective on a wide range of contaminants, including chlorinated
solvents (PCE, TCE, DCE, TCE, DCA, vinyl chloride, carbon tetrachloride), petroleum hydrocarbons (BTEX, GRO,
DRO), aromatic hydrocarbons, chlorinated benzenes, pesticides and others (examples include MTBE, 1,4-
dioxane). The target pH range for effective persulfate activation is 10.5 – 12, with efficacy dropping significantly
below a pH of 10. Sodium hydroxide (NaOH) is often the chemical of choice for injection applications, whereas
lime is often used as the pH modifier when in situ or ex situ soil blending is performed.
Chemicals with very high pH’s can be corrosive to the skin and may cause severe burns and / or blindness.
As a result, it is very critical that the appropriate SDS be reviewed by all staff that may come in contact with the
NaOH or lime, and that the proper protective equipment be utilized at all times, including chemically resistant
gloves, clothing and boots, and face shields and goggles to protect the eyes. NaOH can be purchased in many
forms, including solid (pellets or prills) or in solution with concentrations ranging up to 70% or more. Care must be
taken when mixing NaOH into tanks of water, as NaOH has a very high heat of mixing or dilution, –44.45 kJ / mol,
and can release significant quantities of heat when diluted. Mixing highly concentrated solutions of NaOH, or solid
NaOH, requires long addition periods and large heat reservoirs to
dissipate the generated heat. It is always recommended to use
NaOH in solutions of 25% or less. At or below these concentrations,
the majority of the heat of mixing is gone, and the product is much
safer to use. The sale of Klozur Caustic is offered, a 25%
environmental grade NaOH solution to our customers.
Klozur persulfate and low concentrations of NaOH can be
injected into the subsurface in a sequential manner or they can be
pre-mixed in a tank prior to application. If pre-mixed, it is suggested
that the resulting solution be injected into the ground within a couple
of hours to prevent loss of persulfate through decomposition.
Recent field experience has indicated the potential of concentrated
mixtures of Klozur perulfate and NaOH to form crystals, both in the
mix tank and within injection wells. Individually, the onset of
crystallization of Klozur Caustic occurs at 10.4 °F and Klozur
Persulfate solutions can be made up to 37 wt% at 32 °F before crystallization occurs. Environmental Labs tested
various concentration combinations of Klozur Persulfate and Klozur Caustic at 36 and 68 °F (2 and 20 °C) to

investigate under which conditions crystallization occurs. The results for the 36 °F data are shown in Figure 1 (the
68 °F data is very similar). As a result, the following mixing guidelines have been developed to prevent the
formation of crystals.

NaOH solutions are denser than water (10.6 lb / gal at 25 wt%, 9.27 lb /gal at 20 wt%). As a result,
whether injected into the subsurface by itself or in combination with Klozur persulfate, the resulting solution may be
more dense than the groundwater and will have a tendency to sink within the aquifer. This should be noted and
designed for, as the density of the solution may result in the persulfate and activator dropping below the target
treatment zone. Injecting lower weight percentage solutions or injecting nearer the top of the treatment zone may
allow for longer contact times between the oxidant and contaminants of concern.
FeEDTA Activation

Klozur Persulfate can be activated with chelated iron for the oxidative destruction of organic contaminants
of concern, including PCE, TCE, DCE, vinyl chloride, BTEX, low molecular weight aromatic hydrocarbons, methyl-
tert-butyl ether (MTBE), 1,4-dioxane and others. For chelated iron activation of Klozur Persulfate, the iron
concentration in the groundwater needs to be maintained between 150 mg / L (ppm) and 600 mg / L (ppm). Iron
concentrations below 150 ppm will result in kinetics that may not be favorable for the oxidation of various
contaminants, and concentrations in excess of 600 ppm may lead to increased persulfate auto-decomposition.
One example of a chelated iron is Dissovline® Fe – EDTA, which is 13% iron by weight, thus requiring between
1,154 ppm and 4,615 ppm FeEDTA to maintain the desired groundwater iron concentrations. FeEDTA has a
relatively low solubility, and at 32 °F, will only be soluble up to 5.1 wt%. The solubility only increases to 9 wt% at
68 °F. Other chelated iron complexes are available, such as iron citrate. It is recommended to add chlelated iron
when iron activation is selected, even if there is iron already present in the sub-surface. Measured iron
concentrations present in soils may not be available for persulfate activation or the iron may not be distributed
evenly enough through the treatment zone to insure adequate activation of the persulfate.
The target groundwater FeEDTA concentration is not dependent upon the amount of Klozur persulfate
being applied, but rather on the volume of groundwater being treated. As a result, the ratio of FeEDTA to persulfate
will vary from project to project, leading to the potential for the need to combine high concentrations of Klozur
persulfate and FeEDTA to achieve the desired groundwater concentrations for a given application. FeEDTA is

[e-mail] | 1.866.860.4760 | peroxychem.com/remediation

Peroxygen Talk

comprised of iron as the activator and an organic ligand (EDTA, ethyldiaminetetracetic acid) which itself is
oxidizeable. Because of this, addition of high levels of FeEDTA to concentrated persulfate solutions may lead to
decomposition of the Klozur persulfate at certain concentration combinations. This would lead to loss of the oxidant
and potentially generate excessive heating of the activated persulfate solution. It is not well defined under which
combinations of FeEDTA and persulfate concentrations leads to persulfate decomposition. Consequently, it is
recommended that that the Klozur persulfate and the FeEDTA, or any other type of chelated iron, be made into
solution in separate batch tanks and only combined in-line prior to the well head or injected into the subsurface in a
sequential manner.

Hydrogen Peroxide Activation

Hydrogen peroxide – activated persulfate has been demonstrated effective in the field on a wide range of
organic contaminants, including chlorinated ethenes, ethanes and methanes, BTEX, petroleum hydrocarbons,
MTBE, aromatic hydrocarbons and others. The target molar ratio of hydrogen peroxide to Klozur persulfate is 5:1
to 10:1, or 0.7:1 – 1.4:1 on a pound (100% peroxide) to pound basis. The higher the hydrogen peroxide loading as
compared to the amount of persulfate, the faster the contaminant reaction kinetics will be, but the shorter the
persulfate lifetime.
Hydrogen peroxide is sold commercially in a variety of concentrations. Common concentrations include
70%, 50%, 17.5%, and 8%. Highly concentrated forms of hydrogen peroxide may generate extreme exothermic
reactions upon injection into the subsurface or when contacting high levels of contamination, potentially liberating
significant quantities of gas. Care must be taken to avoid excessive heat and gas evolution as this may cause
damage to utilities, buildings and represents a safety hazard if not properly controlled. It is recommended that
hydrogen peroxide solutions of no more than 8% by weight be used to activate Klozur persulfate. This will help to
minimize the generation of heat and gas upon injection of hydrogen peroxide into the subsurface. Use of
concentrated hydrogen peroxide solutions in excess of 8 wt% may increase the risk of injury, loss of product
containment and equipment damage. Hydrogen peroxide can be applied with persulfate either in a sequential
manner, with the persulfate typically being injected first, or pre-mixed in a tank and co-injected. It is always safer to
inject the materials sequentially For co-injection, it is recommended that the following maximum ratios of hydrogen
peroxide and persulfate than can be pre-mixed:
 No more than 5 gallons of 8% hydrogen peroxide should be added per gallon of 30% Klozur solution

 No more than 3 gallons of 8% hydrogen peroxide should be added per gallon of 20% Klozur solution

 No more than 2 gallons of 8% hydrogen peroxide should be added per gallon o 10% Klozur solution

Always use clean water and clean mixing and handling equipment. Transition metals in the supply water,
such as iron, can result in rapid decomposition of the hydrogen peroxide. It is recommended that oxidant solutions
be injected promptly into the subsurface and avoid delays resulting in the solutions remaining in mix tanks for
extended periods of time. Also use vented tanks and piping when using oxidizing solutions. Always drain lines to
empty and avoid trapping solution between valves for extended periods of time. Do not “dead head” pumps. When
injecting hydrogen peroxide solutions, it is recommended that temperature and back-pressure be monitored and
controlled to prevent highly exothermic, subsurface reactions. Clean all equipment with a water flush after use to
remove any residual oxidant.

Alkaline Activated Klozur® Persulfate
Alkaline activated Klozur® persulfate, U.S Patent No.: 7,576,254 and its foreign counterparts, is a widely used technology
capable of remediating most common organic contaminants of concern. Alkaline activated persulfate forms oxidative
radical species, reductants, and nucleophiles (Furman et al, 2010). This multi-radical attack allows the treatment of
chlorinated ethenes (TCE, PCE, DCE, and vinyl chloride), 1,4-dioxane, MTBE, TBA, petroleum hydrocarbons (BTEX,
and PAHs), pesticides, as well as more recalcitrant compounds including chlorinated methanes, such as carbon
tetrachloride, and chlorinated ethanes, such as 1,1,1-trichloroethane. For a complete list, please contact your
PeroxyChem technical representative or consult www.peroxychem.com/remediation.
ALKALI REAGENT SELECTION
Common reagents used to create alkaline conditions for activation of Klozur persulfate include:
 25 Percent Sodium Hydroxide, 25% NaOH, liquid
The use of 25 percent sodium hydroxide (NaOH) is recommended for safety and handling considerations as 25
percent NaOH releases less heat upon dilution and remains in solution at lower temperatures than more
concentrated forms of NaOH. For more information please consult PeroxyChem’s Technical Bulletin on Crystal
Formation in Solutions of Klozur Persulfate and Klozur Caustic or contact your local PeroxyChem technical
representative.
 Calcium Hydroxide, Ca(OH)2, solid
Calcium hydroxide [Ca(OH)2] is commonly referred to as slaked lime, hydrated lime, or caustic lime. Calcium
hydroxide is recommended over calcium oxide (CaO) in most circumstances as calcium hydroxide releases
significantly less heat (less exothermic) than calcium oxide upon hydration. Both lime products can generate the
alkaline conditions to activate Klozur persulfate when dosed appropriately.
 Calcium Oxide, CaO, solid
Calcium oxide (CaO) is also commonly referred to as quicklime. Calcium oxide releases significant heat
(exothermic) once hydrated as the calcium oxide consumes water to form calcium hydroxide [Ca(OH)2] in a
process referred to as “slaking.” Even when mixed directly with hydrated soil, it can release sufficient heat energy
to create heat activated conditions for persulfate. Health, safety and handling of the expected evolution of heat
should be considered when using calcium oxide to activate persulfate.
 Portland Cement, solid
Portland cement contains a significant amount of calcium oxide with the other major components including silicon
dioxide, aluminum oxides and gypsum. Portland cement has been applied with Klozur persulfate to improve the
geotechnical characteristics of the soil post mixing. At higher dosage rates, Portland cement can provide a
combined remedy that both reduces contaminant mass (via In Situ Chemical Oxidation, ISCO) and contaminant
flux (via In Situ Stabilization, ISS) from a single application. As with calcium hydroxide above, it is recommended
the potential heat evolution of the system be considered prior to field application.

Activation Guide

[e-mail] | 1.866.860.4760 | peroxychem.com/remediation
Due to a number of health and safety concerns, the following alkali reagents are NOT RECOMMENDED for use with
Klozur persulfate:
 High purity Sodium Hydroxide flakes, granules or powder, solid Not Recommended
Solid forms of sodium hydroxide release significant heat (highly exothermic) upon hydration. In certain
circumstances, sufficient heat may be liberated that it can boil the solution, generate steam eruptions, and
damage to equipment.
 Sodium Hydroxide, >25% NaOH, liquid Not Recommended
Sodium Hydroxide is sold commercially in a variety of concentrations. To minimize potential risk, PeroxyChem
recommends NaOH solutions of no more than 25% by weight be used to activate Klozur persulfate. More
concentrated forms of NaOH (50 % or greater solutions and solid form NaOH) may generate increasingly
exothermic reactions upon dilution and any NaOH solution greater than 30% can solidify above the freezing point
of water.
 Carbonate based lime products, solid Not Recommended
Different types of lime exist that are not based on calcium hydroxide or calcium oxide but are instead based on
carbonates or contain a significant amount of carbonates. These forms of lime, such as Agricultural lime, should
not be used to create alkaline activated conditions as the carbonates can interfere with the oxidative treatment
process.

There are several factors to using a lime reagent (calcium hydroxide or calcium oxide) that should be considered
including:
Purity
Commercially available lime products typically include impurities. For example, high purity
commercial lime products might have greater than 95 percent of the desired lime product (calcium
hydroxide or calcium oxide) while other commercially available lime products could have
significantly lower percentages of the desired lime product. These impurities have the potential to
introduce an unexpected compound into the subsurface, such as carbonates (see below), and
necessitate adjusting the total mass of product required to supply the intended amount of calcium
hydroxide or calcium oxide.
Carbonates
Carbonates are common impurities in solid lime products, which have the ability to react with, or
scavenge, certain oxidative radicals which could negatively impact the efficacy of the persulfate.
Trace levels of carbonates are not expected to be a significant issue, however products containing
significant carbonates should either be avoided or bench tested to assess their treatment efficacy.
Calcium sulfate
Residual calcium from the lime will react with residual sulfate from persulfate to form gypsum.
This reaction can significantly reduce the amount of soluble sulfate in the system and it has been
used to increase soil strength.

DETERMINING THE AMOUNT OF ACTIVATOR NEEDED
Alkaline activation typically requires system conditions of at least pH 10.5 be maintained throughout active treatment with
the Klozur persulfate. Klozur CR is formulated with PermeOx Ultra in sufficient quantities to create alkaline conditions in
typical conditions. Klozur SP (sodium persulfate) and Klozur KP (potassium persulfate) require the addition of an alkaline
material.
The demand for alkalinity arises from two sources:
1) Natural demand from soil and groundwater, and
2) The neutralization of acid generated during reactions with persulfate.
Natural Demand for Alkalinity
The amount of the 25% NaOH needed to raise soil and groundwater to pH 10.5 is best determined experimentally.
PeroxyChem recommends a base buffer capacity (BBC) test be conducted to determine this amount. This test is
conducted using aqueous NaOH with the results reported as grams 25 percent NaOH per Kg soil. These values can be
converted to calcium hydroxide or calcium oxide instead of 25 percent NaOH using conversion factors, estimated below:
 0.23 g calcium hydroxide per g of 25 percent NaOH
 0.175 g calcium oxide per g 25 percent NaOH
Please contact PeroxyChem for further information or to inquire about the BBC test offered by our laboratory.
Alkalinity to Neutralize Generated Acid
PeroxyChem recommends adding sufficient alkalinity to account for the decomposition of all of the Klozur persulfate so
that the persulfate system stays sufficiently alkaline until all of the Klozur persulfate is consumed. As persulfate reacts,
it typically forms 2 moles of acid for every mole of persulfate that decomposes. The demand for the amount of an alkali
reagent required to neutralize the acid generated during persulfate decomposition is presented in Table 1.

Portland cement, pozzolans, bentonite, or other materials can be used in differing amounts to help control post soil mixing
soil characteristics including in sufficient quantities to solidify the soil resulting in a combined ISCO and ISS remedy. The
amount of Portland cement needed to solidify the soils may be different than the amount needed to activate the persulfate.
The quantities of Portland cement required to activate persulfate and result in the desired soil characteristic should each
be assessed and, typically, the greater mass used. It is also recommended that soil stability tests be run on site soils
including the Klozur persulfate.
The following examples demonstrate how to estimate the amount of alkali needed at a site to create alkaline activated
conditions.
Example 1:
100,000 lbs of Klozur SP is going to be applied to a site with a base buffering capacity of 5 g 25% NaOH/Kg soil. There
are 8,000,000 Kg soil within the target interval of 30 ft bgs to 40 ft bgs at the site. The use of liquid activator, 25 percent
NaOH, has been selected.
Calculations:
 Part 1 – BBC. The amount due to base buffer capacity of the soil can be determined by multiplying 5 g 25% NaOH
per Kg soil by 8,000,000 Kg soil. This is equal to 40 million grams of 25 percent NaOH solution, or 88,105 lbs.
 Part 2 – Persulfate Neutralization. The amount of 25% NaOH needed to offset the acid generated from persulfate
decomposition would be 1.34 lbs of 25% NaOH times the 100,000 lbs of Klozur SP which equals 134,000 lbs of
25% NaOH solution.
 The final amount of 25% NaOH required at the site would be the addition of the two, or 88,105 + 134,000 = 222,105
lbs of 25% NaOH.
Example 2:
25,000 Kgs of Klozur KP is going to be applied to a site with a base buffering capacity of 3 g 25% NaOH/Kg soil. There
are 3,000,000 Kg soil within the target area at the site. As the target interval is 1 m bgs to 4 m bgs and 98% pure hydrated
lime (calcium hydroxide) has been selected as the activator.
Calculations:
 Part 1 – BBC. The amount due to base buffer capacity of the soil can be determined by multiplying 3 g 25% NaOH
per Kg soil by 3,000,000 Kg soil times the conversion factor of 0.23. This is equal to 2.07 million grams of hydrated
lime, or 2,070 Kgs.
 Part 2 – Persulfate Neutralization. The amount of hydrated lime needed to offset the acid generated from persulfate
decomposition would be 25,000 Kgs of Klozur KP times 0.27 Kgs of hydrated lime per Kg Klozur KP divided by
0.98 (purity) which equals 6,887 Kgs of hydrated lime.
 The final amount of calcium hydroxide (hydrated lime) required at the site would be a combination of the two, or
2,070 + 6,887 = 8,957 Kgs of hydrated lime.
Example 3:
It has been decided to apply the combined remedy of activated Klozur SP and ISS to treat a large brownfield site. It has
been estimated that the site needs a minimum of 400,000 lbs of Klozur SP and has a base buffering capacity of 2 g 25%
NaOH/Kg soil. There are an estimated 26,000,000 lbs of soil within the target area at the site. To stabilize the soils,
Portland cement has been selected as the activator. The Portland Cement to be used was identified as being 63 percent

calcium oxide and it was determined that 8 percent Portland Cement (w/w with the soil mass only) sufficiently stabilized
the soils.
Calculations:
 Part 1 – BBC. The amount due to base buffer capacity of the soil can be determined by multiplying 2 g 25% NaOH
per Kg soil by 26,000,000 lbs soil, dividing by 2.204 lbs/Kg and 0.175 conversion from 25% NaOH to CaO. This is
equal to 4.1 million grams of calcium oxide, or 9,100 lbs of calcium oxide.
 Part 2 – Persulfate Neutralization. The amount of hydrated lime needed to offset the acid generated from persulfate
decomposition would be 0.24 lbs of hydrated lime times the 400,000 lbs of Klozur SP which equals 96,000 lbs of
calcium oxide.
 The final amount of 100% pure calcium oxide (quicklime) required at the site for ISCO would be a combination of
the two, or 9,100 + 96,000 = 105,100 lbs of calcium oxide. As the Portland Cement is specified as having 63
percent calcium oxide, this would be equivalent to 105,100/0.63 = 166,825 lbs of Portland Cement required to
activate Klozur SP.
 The final step would be to compare the amount of Portland cement needed for alkaline activation against the
amount that was determined best to stabilize soils. The amount of Portland cement needed in this example to
stabilize the soils was 8 percent of the original soil mass. The total mass at the site would be 8 percent of
26,000,000 lbs of soil or 2,080,000 lbs of Portland cement. In this case the amount of Portland cement needed to
stabilize the soils exceeded the amount needed to activate persulfate and should be used in the design.
SAFETY AND HANDLING
As the combination of an alkali reagent with persulfate can initiate a reaction, PeroxyChem recommends Klozur
products and alkaline products be stored separately. Even after being batched, PeroxyChem recommends that
the Klozur persulfate and alkaline solutions be stored in separate chemically compatible tanks. Contact between
the alkali material and persulfate prior to injection should be limited to prevent the initiation of the reaction. This is typically
accomplished by mixing the reagents inline prior to injection or injecting the reagents separately in a serial manner that
creates sufficiently alkaline conditions to activate the persulfate.
Alkaline activated Klozur persulfate has been applied safely and effectively at numerous sites. However, as with any
chemical, proper procedures and equipment are recommended in its use. When working with Klozur persulfate, ensure
to have adequate ventilation and use the appropriate personal protective equipment, including safety glasses, suitable
protective clothing, boots (steel toed), chemical resistant gloves, hard hat, and hearing protection (when direct push is
used). For dust, splash, mist, or spray exposures wear a filtering dust mask and chemical protective goggles. A face
shield can also be used in addition to goggles.
Please consult the appropriate Safety Data Sheets (SDS) for guidelines regarding proper handling procedures. The
SDS’s for Klozur persulfate products can be found at: http://www.peroxychem.com/remediation. Additional safety
equipment may be required for mechanical and site operations.
