Remedial Action Work Plan -Revision I
Reasor Chemical Site Remediation -Castle Hayne, North Carolina
EPA ID Number NCD986/87094
1.0 INTRODUCTION
February 2007
Section I
This Remedial Action Work Plan (RAP) presents the procedures and protocols required for implementing
the remediation of the Reasor Chemical Superfund Site (Site) in Castle Hayne, New Hanover County,
North Carolina. Implementation of the RAP will ensure that remedial actions are performed in
accordance with the Record of Decision and amendments (ROD). The specific tasks associated with the
remedial action include site preparation; installation of a water treatment system; installation of a
decontamination area; installation of soil and sediment staging areas; performance of remedial actions
including pond dewatering, water treatment and disposal, pond sediment removal and stabilization and
off-site disposal, drum debris removal and off-site disposal, and soil removal from Copper Scrap and Pipe
Shop areas; installation of alkaline material in Drum Disposal Area; groundwater sampling of existing
monitoring wells MW-7S and 70; closure of remaining wells on Site; and demobilization. This RAP has
been prepared in accordance with the United States Environmental Protection Agency (EPA) issued
Consent Decree (CD) and Statement of Work for Remedial Action (SOW), both dated October 2006.
I.I Facility Location
The Site is located in Castle Hayne, New Hanover County, North Carolina at 5100 North College Road
just southeast of the junction of United States Highway I l 7_and North Carolina Route 132 within a 52.93
acre tract of vacant land (Figure I). Access to the Site is via a dirt access road with a lockable gate.
1.2 Historic Property Use and Ownership
Prior to 1959, the property consisted of woodlands with a small creek through the property. Between
1959 until December I, 1971 the Site was operated and owned by Reasor Chemical Company and was
used for the processing of wood stumps for the recovery of pine products. These products included
turpentine, pine rosin, pine oil, camphor, pine tar and charcoal. The Site was then purchased by the
Martin Marietta Company (now Martin Marietta Materials). A fire and possible explosion occurred at the
Site on April 7, 1972 in which most of the Site buildings were damaged or destroyed. In 1986, the
property was sold to Hilda C. Dill and Jane C. Sullivan. Since 1972, the property has been vacant.
1.3 General Site Layout
Remnants of the fonner pine tree processing facility are evident at the Site. Certain buildings· remain
standing as well as tank cradles and four surface impoundments (Ponds I through 4) which iire oelieved
to have been part of the processing operation. There are also areas where surface disposal of'copper scrap
occurred (Copper Scrap Area), a pipe shop where surface disposal of pipe materials occurred"(Pipe' Shop
Area), and ~ '8Wale where drums containing unknown materials where stored and/or disposed'·1(Dnim

3.0 REMEDY
3.1 Components
The components and selected treatments for each of the four media are the following:
3.2
• SOIL: Direct excavation followed by disposal (if characterized as non-hazardous
waste) into a Subtitle D landfill.
• SEDIMENT: Dewatering of the four process ponds, excavation of the sediment, and
stabilization of the sediment using a natural or man-made stabilizing agent and
disposal (if characterized as non-hazardous waste) in a Subtitle D landfill.
• SURFACE WATER: Removal of the water from the four process ponds, on-site
treatment of the water to remove the contaminants of concern and on-site disposal of
the treated water.
• GROUNDWATER: Placement of alkaline material in the soils at the former Drum
Disposal Area. Sampling of two wells, MW-7S and MW-7D, using low-flow
sampling technology and the collection of groundwater samples for laboratory
analysis for aluminum when pH and turbidity values are within specified limits.
Repeat the sampling annually until four years of monitoring has been performed.
Close remaining on-site wells in accordance with State of North Carolina regulations.
• GENERAL SITE: Restore the Site by planting native species where needed to
mitigate Site impacts due to remediation efforts. Also as needed, install erosion
control technology to mitigate the on-site and off-site erosion due to rainfall.
Performance Standards
The remedial action performance will be measured against the published clean-up standards in the ROD
and amendments. The published clean-up standards are presented in this RAP in Table 1. For
background on the selection of these values, the ROD should be reviewed.
3.3 Compliance Testing
Verification-of the completion of the remedial action will be measured against the clean-up standards
using the sampling and analysis procedures detailed in ·the Pcrfomiance Standards Verification Plan.
Summarizing; soii sampler. will be collected from each of the seven areas requiring excavation and
analyzed fer the presJnce of th~ specific chemicals listed iii Table l.

4.0 REMEDIAL ACTION
The following sections describe the general sequence of construction for the implementation of the
Remedial Actions at the Site. A schedule is provided as Appendix D. This schedule will act as a guide to
the perfonnance of the work. Monthly Progress Reports will provide updates to this schedule as the
remedial action proceeds at the Site. Deviations from this schedule may be necessary due to unforeseen
issues that are inherent in the execution of the work or delays due to weather.
4.1 Mobilization
Mobilization will occur during the first week of field activities. The first site activity will be a Site Safety
Meeting. At this time the Site Safety Officer will review the components of the Health and
Safety/Contingency Plan with the field crews and verify compliance with all the requirements within the
plan.
Apex will also conduct a Construction Kick-Off meeting to review the scope of work and discuss specific
issues related to the Remedial Action.
The following activities will also occur during Mobilization:
•
•
Establishment of Site Security-On-site fences and other barriers will be erected in order to
isolate areas of contamination and prevent migration of the constituents.
Establishment of Field Office and Sanitary Facilities-An on-site field office and sanitary
facilities will be erected in designated locations for on-site workers to utilize during all
phases of field activities.
• Delivery of Equipment and Personnel-All personnel will arrive at the site for the
commencement of field activities. All equipment needed for field activities is to be delivered
at or before the commencement of field activities. All equipment will be stored in a
designated area on site so as to minimize cross-contamination of affected areas.
• Establishment of Decontamination Facilities-Decontamination facilities will be erected for
· each affected area at the site. Excavation will be accomplished with either a backhoe or track
hoe and material will be directly loaded onto dump trucks. The trucks will be brushed clean
of any soil that may have spilled during loading. Care will be taken to prevent
•. vehicles/trucks from driving over any area identified for remediation. If it is determined to be
·-' necessary based on observations during loading operations, plastic may be rolled out to
prevent the trnck tires from contacling contaminated material. Once the material is loaded
Apex will ·complete an appropriate manifost prior to the material lea,~ng the site.

• Delivery a,;d Set.Up of Surface Water Treatment Components-Components of the
surface water treatment facility will be delivered and assembled approximately two weeks
prior to soil remediation activities. This ensures that the surface waters will be sufficiently
removed from the underlying soils and sludge for soil removal activities to take place.
• Clearing and Access to Work Areas-At the time the surface water treatment facility is .
erected, personnel will visit all affected areas at the Site in order to ensure vegetation or other
obstacles are cleared from all work areas.
Soil Remedial Action
The ROD identifies three areas that have contamination detected above the clean-up levels. These areas
are the Scrap Copper Area, the Drum Disposal Area, and the Pipe Shop Area. The ROD selected remedy
for these areas is excavation and off-site disposal. Apex has been in discussion with New Hanover
County Solid Waste Management and has tentatively reached agreement with them to receive the
sediment, soils and metal debris from the Site (see Section 4.9 for details). After completion of the
removal of the impacted soils, native backfill (sand and silt) from the surrounding property will be placed
into the respective excavations. Since each of the excavations is very shallow, the backfill will be placed
in one lift. The location of these areas is shown on Figure 2.
4.2.l Scrap Copper Area
The Remedial Action in the Scrap Copper Area involves the removal and disposal of soil m an area
measuring approximately 50 feet long by 50 feet wide and one foot deep. This excavation will result in
the removal of approximately 92 cubic yards of material.
Prior to excavation Apex will collect a composite sample within the proposed excavation to characterize
the soil for disposal. The results of this sampling will determine the appropriate disposal location. From
the previously generated data, Apex is anticipating the classification of these soils as non-hazardous and
we are planning on the disposal of these soils in a Subtitle D landfill.
Excavation will be accomplished with either a backhoe or track hoe and material will be directly loaded
onto dump trucks. The trucks will be brushed clean of any soil that may have spilled during loading.
Care will be taken to prevent vehicles/trucks from driving over any area identified for remediation. !fit is,.

Once the laboratory analysis is complete and the preliminary results are evaluated Apex will backfill the
excavated area with imported fill or on-site borrow material. The area will be graded to provide positive ..
drainage away from the former Scrap Copper Area and the surface will be stabilized with straw or
temporary erosion control matting.
4.2.2 Drum Disposal Area
The Remedial Action in the Drum Disposal Area involves the removal and disposal of drums and soil in
an area measuring approximately 120 feet long by 50 feet wide and one foot deep. The area contains
remnants of drums that appear to have been used during the processing of wood products. The drums are
essentially rusted shells with some drums containing solid residue. This excavation will result in the
removal of approximately 222 cubic yards of material.
Prior to excavation Apex will ·collect a composite sample within the proposed excavation to characterize
the soil for disposal.· The results of this sampling will determine the appropriate disposal location. From
the previously generated data, Apex is anticipating the classification of these drums and soils as non-
hazardous and we are planning on the disposal of these soils in a Subtitle D landfill.
Excavation will be accomplished with either a backhoe or track hoe and material will be directly loaded
onto dump trucks.. Removed drums will be segregated to extent possible. Drum removal will be
accomplished using a track hoe with a thumb attachment for grasping the drums. Physical condition of
the drums precludes the need for over packing. Drums removed from the site will be sent to a Subtitle D
landfill. The trucks will be brushed clean of any soil that may have spilled during loading. Care will be
taken to prevent vehicles/trucks from driving over any area identified for remediation. If it is determined
to be necessary based on observations during loading operations, plastic may be rolled out to prevent the
truck tires from contacting contaminated material. Once the material is loaded Apex will complete an
appropriate manifest prior to the material leaving the site.
l ,,,,.'
Upon completion of the specified excavation, three verification samples will be collected to confirm the.", ,
adequacy of the Remedial Action. The Drum Disposal Area will be divided into three 40-foot by 50,fobt· ,,,. ,, , , , .

·Once the laboratory analysis is complete and the preliminary . .results are evaluated Apex will install either
quicklime or granulated li111t·sio'1ie over the entire e~~~vation. The amount of material to be added has
been calculated to be 2,500 pounds. The quantity of limestone has been calculated based on the solubility
of the calcium hydroxide (0.0 I I pounds/gallon), an aquifer porosity of 30-percent and an aquifer
thickness of 20-feet. The quantity of limestone will then "treat" approximately I 0,000 square feet of area.
The material will be spread using the excavation machine and by hand. After the alkaline material has
been added, Apex will backfill the excavated area with imported fill or on-site borrow material. The area
will be graded to provide positive drainage away from the former Drum Disposal Area and the surface
will be stabilized with straw or temporary erosion control matting.
4.2.3 Pipe Shop Area
The Remedial Action m the Pipe Shop Area involves the removal and disposal of soil in an area
measuring approximately 20 feet long by 40 feet wide and one foot deep. This excavation will result in
the removal of approximately 30 cubic yards of material.
Prior to excavation Apex will collect a composite sample within the proposed excavation to characterize.
the soil for disposal. The results of this sampling will determine the appropriate disposal location. From
the previously generated data, Apex is anticipating the classification of these soils as non-hazardous and
we are planning on the disposal of these soils in a;Subtitle D landfill.
Excavation will be accomplished with either a backhoe or track hoe and material will be directly loaded
onto dump trucks. The trucks will be brushed clean of any soil that may have spilled during loading.
Care will be taken to prevent vehicles/trucks from driving over any area identified for remediation. If it is
determined to be necessary based on observations during loading operations, plastic may be rolled out to

Sediment Remedial Action _,.
The ROD identified four process ponds that were incorporated into the Remedial Action. The ponds are
identified as, Pond I (approximately 110 x 60 feet), Pond 2 (approximately 80 x 50 feet), Pond 3
(approximately 70 x 40 feet), and Pond 4 {approximately 70 x 60 feet). The ROD selected remedy for the
sediments in these Ponds is excavation and off-site disposal. Apex will collect a composite sample from
the removed sediments to characterize the sediment for disposal. The results of this sampling will
determine the appropriate disposal location. From the previously generated data, Apex is anticipating the
classification of these sediments as non-hazardous and we are planning on the disposal of these soils in a
Subtitle D landfill. See Figure 2 for the locations of the ponds and the sediment stabilization area.
Prior to the removal of sediment the surface water impounded at each pond will be removed and treated
with an on-site treatment system prior to discharge onsite. Complete detail on the water treatment system
is provided in the following section.
Apex will prepare a staging area (likely to be the concrete pad adjacent to the Extractor) where the
sediments will be placed during removal from the ponds. This area will be modified to allow for the
drainage of any water from the staging area back into Pond 2. This modification is expected to include
the grading of the pad to the edge of Pond 2. Where this excavation removes the concrete, Apex will
install polyethylene sheeting to prevent water from impacting the soil. In coordination with the landfill
operator and based on material availability, Apex will then blend either a natural material such as wood
chips or sawdust or a man-made material such as cement kiln dust to stabilize the sediment prior to
disposal in a Subtitle D landfill. These added materials will be used to create a material that passes the
paint filter liquid test which is the primary test that Apex is expecting the Solid Waste Authority to
require. The selected material(s) will be brought on-site on an as-needed basis to minimize stockpiling.
The stabilized sediment will be placed into dump trucks for hauling to the landfill. The trucks will be
brushed clean of any material that may have spilled during loading. Care will be taken to prevent
vehicles/trucks from driving over any area identified for remediation. If it is determined to be necessary
based on observations during loading operations, plastic may be rolled out to prevent the truck tires from
contacting contaminated material. Once the material is loaded Apex will complete an appropriate
manifest prior to the material leaving the site.
Upon completion of the pond excavations, one verification sample will be collected from the floor of each ..
pond to confirm the adequacy of the Remedial Action. The samples soil.sample will be composited from

Apex will also obtain field measurements to allow for the preparation of as-built drawings to record final
dimensions of the remediated area. Sampling location and methodology are discussed in the PSVP.
Once the laboratory analysis is complete and the preliminary results are evaluated Apex will install
erosion control matting, seeding and other systems to stabilize the pond banks. The ponds will then be
allowed to refill using rainfall, groundwater discharge and surface run-off.
4.4 Surface Water Treatment and Disposal System
While the complete details on the planned water treatment system are subject to rev1s1on, Apex 1s
planning the following sequence of events:
• Dewatering of each pond in sequence using a self-priming centrifugal pump with a
floating suction;
• Filtration of the water while transferring using l00-micron bag filters;
• Temporary storage of the water in an aboveground tank;
• Processing of the water through the treatment system which consists of ion exchange
resin for metals removal followed by activated carbon adsorption for organic
treatment;
• Post-treatment filtration with a 20-micron bag filter; and
• On-site disposal.
Contaminants of concern identified by the EPA during the Remedial Investigation in the surface water
accumulated in the four ponds included the following:
• Metals: aluminum, copper, iron, lead anq zinc ;
• Volatile Organics: toluene, and;
• Semi-volatile organics: fluoranthene, phenanthrene.
The selected treatment processes, _ion-exchange resin for the metals and activated carbon adsorption for
the organics, was specifically selected for these contaminants of concern. The quantities of each material
(resin and carbon) were selected to treat up to 500,000-gallons of water utilizing no more 75-percent of
the media adsorptive capacity. The vendor .supplying the treatment equipment has over 20-years of
experience in processing both dilute (this Site) and concentrated wastewater for the removal of metals and
organic chemicals such·as these found at the Site.:. Concentrations well-below the ROD published cleanup
levels are expected in the system eff1uent.

percent of their respective capacities. If either of these systems reaches this capacity, Apex will change-
out the respective system component with a new unit prior to restarting water treatment. The system as
designed is capable of treating the pond contaminants prior to reaching these treatment capacities.
The water treatment system will be staged adjacent to the spent wood chip storage area near the former
boiler house (see Figure 2). Appendix F provides a schematic and specifications for the proposed system.
Treated surface water will be land-applied using low-pressure spray irrigation equipment within the
boundaries of the site. The planned disposal locations include the site areas adjacent to the boundary
access roads. By utilizing the site for disposal, a permit for the disposal of the treated water does not
require a discharge permit.
4.5 Investigation Derived Wastes·
The EPA has stockpiled drums containing wastes from previous investigations on-site. Liquid contents of
the drums may be processed through the surface water treatment system based on field observations. The
drums will then be removed and disposed of at a Subtitle D landfill as part of the remedial action. These
drums are presumed to contain personnel protective equipment, purge water, soil cuttings, sampling
equipment, small quantities of soils, sludges and possibly ground or surface water collected during the
investigations. These materials will be properly manifested prior to the materials being sent off-site.
4.6 Groundwater
The groundwater contaminants at the Site are likely due to the presence of natural clay lenses which have
been exposed to naturally acidic conditions. The placement of the alkaline material in the soils at the
Drum Disposal Area is expected to significantly impact the groundwater quality. The remaining issue
involves the sampling of the groundwater to minimize the entrainment of fine sediments during the
sampling. Existing groundwater monitoring wells MW-7S and MW-7D will monitored by Apex after
remediation. The remaining wells on the Site will be closed in accordance with State of North Carolina
well abandonment regulations.
To perform this sampling, Apex is going to use the QED low-flow sampling system. This sampling
system consists of an air-operated diaphragm pump, a flow cell which allows the real-time monitoring of
certain parameters, and the ability to accurately control the groundwater withdrawal rate. The monitoring
wells will be purged of three well volumes or until parameters such as pH, turbidity,. specific
conductivity, and dissolved oxygen are stabilized. The EPA publication Environmental Investigations:.-<.\ ·

Apex will record in the project field book the measured values as the wells are purged and when the
sampling takes place. The collected groundwater samples will be placed into laboratory-provided sample
containers, placed in ice and shipped under custody control to the laboratory for analysis. Field records
and laboratory reports will be included in the Five-year report.
The use of the low-flow purging and sampling system has been approved by Region IV of the EPA.
Documentation on the sampling system and EPA approvals are included with this RAP in Appendix E.
Details on the analysis of the samples and types of analyses to be performed are shown in the PSVP.
4.7 Decontamination Procedures
Apex will decontaminate field equipment, including excavation equipment, via steam cleaning.
Decontamination will take place on a lined pad built by Apex between the extractor pad and the copper
scrap area. Water collected in the pad will be pumped through the surface water treatment system and
disposed of on-site.
4.8 Management of Remediation Efforts
The Apex Project Management Plan is included with this work plan in Appendix A. Summarizing, Apex
will be using a designated manager structure where the remediation team (Remediation Superintendent)
will report independently to Apex's Director of Remediation, Mr. Michael Yost. . Oversight of the
remediation effort will be provided on-site by the Field Sample Team Leader who reports to the Apex
Project Coordinator. Resolution of any conflicts between the remediation team and the Project
Coordinator will be performed by Mr. Vince Direnzo, who is Chief Operations Officer for Apex.
4.9 Subtitle D Landfill
Apex has had preliminary discussions with New Hanover County concerning the use of their current
landfill as the disposal location of excavated and treated sediment, soils and drums from the remedial
action. The county has requested and Apex will provide specific historical sampling results for these
wastes for profiling purposes. Apex is expecting that these sampling results along with field testing for
"free" liquids will meet the county requirements for use of their landfill. Apex will provide media.testing
as needed by the county for our use of-the landfill as the disposal location. Apex is not aware. of any· ,. •«,. i-',·, •.
ongoing compliance issues regarding the New-Hanover County active landfill.

Internal communica:.ion between Apex and the Owners or Owners Agents will be performed only
by the Project Coordinator or alternate. All internal Apex communication shall be copied to the
Project Coordinator and alternates.
External communication, when needed, between Apex and the regulatory agencies falls into two
subsets. Formal communication; letters, requests for changes to project and repof\s, must be
reviewed by the Owners Agents/Prior Owner Agent prior to transmittal to either of the regulatory
agencies. Discussions occurring at the Site during field activities are the second subset. Requests
for information from representatives of the agencies will need to be evaluated to determine if the
topic being discussed will impact deliverables or schedule for the project. If the field
communication has the possibility to impact either item, the Project Coordinator must be
contacted to clarify/provide the answer. If not, the Apex team member is to contact the senior on-
site Apex team member to provide the answer to the agencies request. ALL
COMMUNICATION (FIELD NOTES, PHONE LOGS, EMAIL) IS TO BE COPIED TO
THE PROJECT COORDINATOR FOR REVIEW AND FILING.
Transmittals to the regulatory agencies shall be done using either Certified-Return Receipt
Requested US Mail or via an overnight carrier service such as Federal Express. Proof of delivery
must be retained in the project files. For the carrier services, email notification of delivery is
acceptable for proof of delivery.

OPERATIONS AND MAINTENANCE PLAN
This Operations· and· Maintenance Plan (O&M Plan) covers the field activities needed to be
performed after completion of the remedial actions at the Reasor Chemical Superfund Site in
Castle Hayne, North Carolina (Site). The activities covered by this O&M Plan include field
inspections of the Site for soil erosion and differential settling, the establishment of vegetation
and the annual sampling of two existing groundwater monitoring wells.
FIELD SITE INSPECTION
Field inspections shall be performed twice during the first year after completion of the remedial
action and then yearly until the completion of the four-year groundwater monitoring program.
The inspections shall include the following:
• Review and photo documentation of pond embankments for erosion and
identification of banking areas needing repair;
• Review of areas where soil excavation activities took place to determine _if
significant settling has occurred;
•
•
Review of establishment of vegetation in the above areas; and
Review of the status of the two existing monitoring wells to _verify the wells
are secured and have not been tampered with.
Documentation of the field inspections shall be performed through the use of a field inspection
memorandum that will document the date of the inspection, person performing the inspection,
results of the pond embankment survey, the results of the soil excavation area surveys and the
identification of any actions required and the schedule of the actions.
The field inspection memorandums will be included with the Five-year Report as appendices to
document the Site conditions.
Habitat V crification / Regeneration Plan
The habitat verification and regeneration component of this plan is designed to ensure the
successful regeneration the open water and wetland habitats impacted by the remedial actions at
the site. The baseline conditions for the habitat restoration will be the conditions documented by
EPA and Weston in June 2003 as well as photo documentation performed by Apex in May 2007.
Regeneration of the open water and wetland habitats will primarily occur by natural recovery
through groundwater infiltration and storm water discharge. Post remediation measures ,will be
.·•. '"taken"ensure ,the shoreline retains wildlife value and promotes successful wetland regeneration.
The post remediation plan for each area is provided below:

monitoring program. The inspections activities shall include the following:
• Photo documentation;
• Reporting (five-year plan); and
• Performing corrective actions, if warranted.
Corrective actions, if required, will consist of the following as deemed appropriate:
• Spreading of seed mix no. 6CP (NC Erosion Control/Sedimentation Guidance Manual);
• Repair of bank erosions; or
Placement of additional geotextile fabric as needed
GROUNDWATER MONITORING
The ROD and amendments specify that existing groundwater monitoring wells MW-7S and MW-
7D will be sampled yearly for the presence of aluminu~. The sampling shall be done using the ·
QED low-flow .sampling system. The sampling system consists of a dedicated bladder type pump

Teflon tubing between the well pump and the flow monitoring chamber.
The ·monitoring chamber shall be QED Model MP-20DT which 1s capable of real-time
monitoring -of ·temperature, pH, dissolved oxygen, conductivity and turbidity. The range .of
' variation for these parameters is as follows:
• Temperature -±0.4° Fahrenheit
• pH -±0.1 Standard units
• Dissolved Oxygen -±0.2 milligrams per liter
• Conductivity -±0.02 microSiemens per centimeter
• Turbidity -±IO NTU
When three of these parameters are within the limits specified, the monitoring chamber will
audibly indicate compliance such that the well has been purged in accordance with EPA
requirements for low-flow sampling and a sample can be collected. The initial purging rate of the
two wells to be sampled will be no more than I 00 milliliters per minute. Placement of the
dedicated well pump, including tubing will take place at least 48-hours prior to collection of a
groundwater sample to minimize the suspension of fine silt and particles in the well.
The sampler shall record the all of the parameters (including turbidity), verify that the pH 1s
within the limits specified in the ROD and amendments (7.2 and 8.5) and collect the sample into
the laboratory-provided containers. The selected laboratory will be providing the sample
containers containing the required preservatives. After collection, the sample containers will be
placed on ice and shipped overnight with proper chain-of-custody procedures and controls.
Control of the well pumps shall be performed using QED Model MP-10 controller. The
controller allows for the repeatable control of well pump operation.
Field records on the sampling shall be placed into the project file system. The Five-year Report

SECTION 7
GROUND WATER SAMPLING
PERFORMANCE OBJECTIVES:
• To collect a sample representative of ground water residing in the formation of interest.
• To reduce the potential bias caused by the sampling equipment used to obtain the sample.
7.1 Introduction
Ground water sampling may be required for a variety of reasons, such as examining potable or
industrial water supplies, checking for and/or tracking contaminant plume movement in the vicinity of a land
disposal or spill site, Resource Conservation Recovery Act (RCRA) compliance monitoring, or examining a
site where historical information is minimal or non-existent but where it is thought that ground water
contamination may have occurred.
Ground water samples are usually obtained from either temporarily or permanently installed ground
water monitoring wells. They can also be obtained, however, anywhere ground water is present, such as in a
pit or a dug or drilled hole.
Occasionally, the ground water source may not be in the ideal location to meet a particular objective
(e.g., to track a contaminant plume). In that case, either a temporary or permanent monitoring well should be
installed. An experienced and knowledgeable person will need to locate the well and supervise its
installation so that samples will be representative of the !,'found water.
Additional !,'llidance is given in RCRA Ground-Water Monitoring: Technical Guidance(!) and
Chapter I I of SW-846 (2). The ground water sampling procedures described in this SOP will meet or
exceed the requirements of these documents.
Ground water sampling procedures can be sub-divided into two areas, purging and sampling, each
of which has different goals and objectives. Within the topic of purging, it is necessary, because of the
inherently different characteristics of the two types of wells, to address permanent and temporary wells
separately. The procedures and techniques which follow in this section reflect these differences. ·
EISOPQAM 7-1 May 1996
7.2 Purging
7.2.1 Purging and Purge Adequacy
Purging is the process of removing stagnant water from a monitoring well, immediately prior to
sampling, causing its replacement by ground water from the adjacent formation, which is representative of
actual aquifer conditions. In order to determine when a well has been adequately purged, field investigators
should: I) monitor the pH, specific conductance, temperature, and turbidity of the ground water removed
during purging; and 2) observe and record the volume of water removed.
Prior to initiating the purge, the amount of water standing in the water column (water inside the well
riser and screen) should be determined. To do this, the diameter of the well should be determined and the
water level and total depth of the well are measured and recorded. Specific methodology for obtaining these
measurements is found in Section 15.8 of this SOP. Once this information is obtained, the volume of water
to be purged can be determined using one of several methods. One is the equation:
V = 0.041 d2h
Where: h = depth of water in feet
d = diameter of well in inches
V = volume of water in gallons
Alternatively, the volume may be determined using a casing volume per foot factor for the
appropriate diameter well, similar to that in Table 7.2.1. The water level is subtracted from the total depth,
providing the length of the water column. This length is multiplied by the factor in the Table 7.2.1 which
corresponds to the appropriate well diameter, providing the amount of water, in gallons, contained in the
well. Other acceptable methods include the use of nomographs or other equations or formulae.
With respect to volume, an adequate purge is normally achieved when three to five times the volume
of standing water in the well has been removed. The field notes should reflect the single well volume
calculations or determinations, according to one of the above methods, and a reference to the appropriate
multiplication of that volume, i.e., a minimum three well volumes, clearly identified as a purge volume goal.
With respect to the ground water chemistry, an adequate purge is achieved when the pH, specific
conductance, and temperature of the ground water have stabilized and the turbidity has either stabilized or is
below IO Nephelometric Turbidity Units (NTUs). Ten NTUs is the goal for most ground water sampling
objectives. This is twice the Primary Drinking Water standard of 5 NTUs. Stabilization occurs when pH
measurements remain constant within 0.1 Standard Unit (SU), specific conductance varies no more that IO
percent, and the temperature is constant for at least three consecutive readings. There are no criteria
establishing how many sets of measurements are adequate for the determination of stability. If the calculated
purge volume is small, the measurements should be taken frequently to provide a sufficient number of
measurements to evaluate stability. If the purge volume is large, measurements taken every 15 minutes may
be sufficient.
If, after three well volumes have been removed, the chemical parameters have not stabilized
according to the above criteria, additional well volumes may be removed. If the parameters have not
stabilized within five volumes, it is at the discretion of the project leader whether or not to collect a sample
or to continue purging. The conditions of sampling should be noted in the field log.

In some situations, even with slow purge rates, a well may be pumped or bailed dry (evacuated). In
these situations, this generally constitutes an adequate purge and the well can be sampled following
sufficient recovery (enough volume to allow filling of all sample containers). It is not necessary that the well
be evacuated three times before it is sampled. The pH, specific conductance, temperature, and turbidity
should be measured, during collection of the sample from the recovered volume, as the measurements of
record for the sampling event.
Attempts should be made to avoid purging wells to dryness. This can be accomplished, for
example, by slowing the purge rate. If a well is pumped dry, it may result in the sample being comprised
partially of water contained in the sand pack, which may be reflective, at least in part, of initial, stagnant
conditions. In addition, as water re-enters a well that is in an evacuated condition, it may cascade down the
sand pack or the well screen, stripping volatile organic constituents that may be present and/or introducing
soil fines into the water column.
EISOl'QAM 7-3 May 1996
Equipment Available
Monitoring well purging is accomplished by using in-place plumbing and dedicated pumps or, by
using portable pumps/equipment when dedicated systems are not present. The equipment may consist of a
variety of pumps, including peristaltic, large and small diameter turbine (electric submersible), bladder,
centrifugal, gear-driven positive displacement, or other appropriate pumps. The use of any of these pumps is
usually a function of the depth of the well being sampled and the amount of water that is to be removed
during purging. Whenever the head difference between the sampling location and the water level is less than
the limit of suction and the volume to be removed is reasonably small, a peristaltic pump should be used for
purging. Appendix E of this SOP contains the operating instructions for all pumps commonly used during
Branch ground water investigations.
Bailers may also be used for purging in appropriate situations, however, their use is discouraged.
Bailers tend to disturb any sediment that may be present in the well, creating or increasing sample turbidity.
If a bailer is used, it should be a closed-top Teflon® bailer.
7.2.2 Purging Techniques (Wells Without Plumbing or In-Place Pumps)
For permanently installed wells, the depth of water and depth of the well should be determined (if
possible) before purging. Electrical water level indicators/well sounders can be used for this purpose. It is
standard practice to mark the top of casing, providing a point of reference from which these measurements
will be consistently made. Field investigators should look for these markings when taking these
measurements. Extreme caution should be exercised during this procedure to prevent cross-contamination of
the wells. This is a critical concern when samples for trace organic compounds or metals analyses are
collected. At a minimum, the well sounding device should be cleaned by washing in a laboratory detergent
solution, followed by rinses with tap water and analyte-free water. After cleaning, it should be placed in a
clean plastic bag or wrapped in foil.
Purging with Pumps
When peristaltic pumps or centrifugal pumps are used, only the intake line is placed into the water
column. The line placed into the water should be either standard-cleaned (see Appendix B) Teflon® tubing,
for peristaltic pumps, or standard-cleaned stainless steel pipe attached to a hose for centrifugal pumps.
When submersible pumps (bladder, turbine, displacement, etc.) are used, the pump itself is lowered
into the water column. The pump must be cleaned as specified in Appendix B.
Purging with Bailers
Standard-cleaned (Appendix B) closed-top Teflon® bailers with Teflon® leaders and new nylon
rope are lowered into top of the water column, allowed to fill, and removed. The water is either discarded or
contained and managed as investigation derived waste. It is critical that bailers be slowly and gently
immersed into the top of the water column, particularly during final stages of purging, to minimize turbidity
and disturbance of volatile organic constituents. The use ofbailers for purging and sampling is discouraged
because the correct technique is highly operator dependent.

Field Care of Purging Equipment
Regardless of which method is used for purging, new plastic sheeting should be placed on the
ground surface around the well casing to prevent contamination of the pumps, hoses, ropes, etc., in the event
they need to be placed on the ground during the purging or they accidentally come into contact with the
ground surface. It is preferable that hoses used in purging that come into contact with the ground water be
kept on a spool or contained in a plastic-lined tub, both during transporting and during field use, to further
minimize contamination from the transporting vehicle or ground surface.
Purging Entire Water Column
The pump/hose assembly or bailer used in purging should be lowered into the top of the standing
water column and not deep into the column. This is done so that the purging will "pull" water from the
formation into the screened area of the well and up through the casing so that the entire static volume can be
removed. If the pump is placed deep into the water column, the water above the pump may not be removed,
and the subsequent samples, particularly if collected with a bailer, may not be representative of the ground
water.
It is recommended that no more than three to five feet of hose be lowered into the water column. If
the recovery rate of the well is faster than the pump rate and no observable draw down occurs, the pump
should be raised until the intake is within one foot of the top of the water column for the duration of purging.
If the pump rate exceeds the recovery rate of the well, the pump will have to be lowered, as needed, to
accommodate the draw down. After the pump is removed from the well, all wetted portions of the hose and
the pump should be cleaned as outlined in Appendix B of this SOP.
Careful consideration shall be given to using pumps to purge wells which are excessively
contaminated with oily compounds, because it may be difficult to adequately decontaminate severely
contaminated pumps under field conditions. When wells of this type are encountered, alternative purging
methods, such as hailers, should be considered.
General Low Flow/Low Stress Method Preference
The device with the lowest pump or water removal rate and the least tendency to stress the well
during purging should be selected for use. For example, if a bailer and a peristaltic pump both work in a
given situation, the pump should be selected because it will greatly minimize turbidity, providing a higher
quality sample (Section 7.2.4 contains a description of low flow purging and sampling with a peristaltic
pump used in a temporary well). If a Fultz® pump or a Grundfos Redi-Flo2® could both be used, the Redi-
Flo2® may be given preference because the speed can be controlled to provide a lower pump rate, thereby
minimizing turbidity.
Low Flow/Low Volume Purging Techniques/Procedures
A ltematives to the low flow purging procedures exist and may be acceptable. The low flow/low
volume purging is a procedure used to minimize purge water volumes. The pump intake is placed within the
screened interval at the zone of sampling, preferably, the zone with the highest flow rate. Low flow rate
purging is conducted after hydraulic conditions within the well have re-stabilized, usually within 24 to 48
hours. Flow rates should not exceed the recharge rate of the aquifer. This is monitored by measuring the top
of the water column with a water level recorder or similar device while pumping. These techniques,
however, are only acceptable under certain hydraulic conditions and are not considered standard procedures.
EISOPQAM 7-5 May 1996
7.2.3 Purging Techniques• Wells with In-Place Plumbing
Wells with in-place plumbing are commonly found at municipal water treatment plants, industrial
water supplies, private residences, etc. Many permanent monitoring wells at active facilities are also
equipped with dedicated, in-place pumps. The objective of purging wells with in-place pumps is the same as
with monitoring wells without in-place pumps, i.e., to ultimately collect a sample representative of the
ground water. Among the types of wells identified in this section, two different approaches are necessary.
The permanent monitoring wells with in-place pumps should, in all respects, be treated like the monitoring
well without pumps. They generally are sampled only occasionally and require purging as described for
wells without in-place pumps, i.e., 3 to 5 well volumes and stable parameters.
In the case of the other types of wells, however, not enough is generally known about the
construction aspects of the wells to apply the same criteria as used for monitoring wells, i.e., 3 to 5 well
volumes. The volume to be purged in these situations, therefore, depends on several factors: whether the
pumps are running continuously or intermittently and whether or not any storage/pressure tanks are located
between the sampling point and the pump. The following considerations and procedures should be followed
when purging wells with in-place plumbing under the conditions described.
Continuously Running Pumps
If the pump runs more or less continuously, no purge (other than opening a valve and allowing it to
flush for a few minutes) is necessary. If a storage tank is present, a spigot, valve or other sampling point
should be located between the pump and the storage tank. If not, locate the valve closest to the tank.
Measurements of pH, specific conductance, temperature, and turbidity are recorded at the time of sampling.
Intermittently Running Pumps
If the pump runs intermittently, it is necessary to determine, if possible, the volume to be purged,
including storage/pressure tanks that are located prior to the sampling location. The pump should then be
run continuously until the required volume has been purged. If construction characteristics are not known,
best judgement should be used in establishing how long to run the pump prior to collecting the sample.
Generally, under these conditions, 30 minutes will be adequate. Measurements of pH, specific conductance,
temperature and turbidity should be made and recorded at intervals during the purge and the final
measurements made at the time of sampling.
7.2.4 Purging Techniques -Temporary Monitoring Wells
Temporary ground water monitoring wells differ from permanent wells because temporary wells are
installed in the ground water for immediate sample acquisition. Wells of this type may include standard well
screen and riser placed in boreholes created by hand augering, power augering, or by drilling. They may
also consist of a rigid rod and screen that is pushed, driven, or hammered into place to the desired sampling
interval, such as the Direct Push Wellpoint®, the Geoprobe® and the Hydropunch®. As such, the efforts to
remove several volumes of water to replace stagnant water do not necessarily apply in these situations,
because generally, stagnant water is non-existent. It is important to note, however, that the longer a
temporary well is in place and not sampled, the more appropriate it may be to apply, to the extent possible,
standard permanent monitoring well purging criteria to it.
In cases where the temporary well is to be sampled immediately after installation, purging is
conducted primarily to mitigate the impacts of installation. In most cases, temporary well installation
procedures disturb the existing aquifer conditions, resulting primarily in increased turbidity. Therefore, the
goal of purging is to reduce the turbidity and remove the volume of water in the area directly impacted by

the installation procedure. Low turbidity samples in these types of wells are typically and routinely achieved
by the use of low-flow purging and sampling techniques.
The following low-flow purging technique using peristaltic pumps has been used routinely to
achieve acceptably low NTU values in a variety of temporary monitoring well applications.
In purging situations where the elevation of the top of the water column is no greater than approx-
imately 25 feet below the pump head elevation, a peristaltic pump may be used to purge temporary wells.
Enough tubing is deployed to reach the bottom of the temporary well screen. At the onset of purging, the
tubing is slowly lowered to the bottom of the screen and is used to remove any fonnation material which
may have entered the well screen during installation. This is critical to ensuring rapid achievement of low
turbidity conditions. After the fonnation material is removed from the bottom of the screen, the tubing is
slowly raised through the water column to near the top of the column. The tubing can be held at this level to
detennine if the pump is lowering the water level in the well. If not, secure the tubing at the surface to
maintain this pumping level.
If the water column is lowered, and the pump is not variable speed, continue to lower the tubing as
the water column is lowered. If a variable speed peristaltic pump is being used and draw down is observed
on initiation of pumping, reduce the pump speed and attempt to match the draw down of the well. Sustained
pumping at these slow rates will usually result in a relatively clear, low turbidity sample. If the draw down
stabilizes, maintain that level, however, if it continues to lower, "chase" the water column until the well is
evacuated. In this case, the recovered water column may be relatively free of turbidity and can be sampled.
It may take several episodes of recovery to provide enough volume for a complete sample.
With many of the direct push sampling techniques, no purging is conducted. The sampling device is
simply pushed to the desired depth and opened and the sample is collected and retrieved.
7.3 Sampling
Sampling is the process of obtaining, containerizing, and preserving the ground water sample after
the purging process is complete. Non-dedicated pumps for sample collection generally should not be used.
Many pumps are made of materials, such as brass, plastic, rubber, or other elastomer products which may
cause chemical interferences with the sample. Their principle of operation may also render them
unacceptable as a sample collection device. The pump may be turbine driven, which may release volatile
organic constituents. It is recognized that there are situations, such as industrial or municipal supply wells or
private residential wells, where a well may be equipped with a dedicated pump from which a sample would
not nonnally be collected. Discretion should always be used in obtaining a sample.
7.3.1 Equipment Available
Because of the problems with most pumps described in the preceding paragraph, only three devices
should be used to collect ground water samples from most wells. These are the peristaltic pump/vacuum jug
assembly, a stainless steel and Teflon® bladder pump, and a closed-top, Teflon® bailer.
Other monitoring equipment used during sampling includes water level indicators, pH meters,
thennometers, conductivity bridges, and nephelometers.
7.3.2 Sampling Techniques -Wells With In-Place Plumbing
Samples should be collected following purging from a valve or cold water tap as near to the well as
EISOPQAM May 1996
possible, preferably prior to any storage/pressure tanks that might be present. Remove any hose that may be
present before sample collection and reduce the flow to a low level to minimize sample disturbance,
particularly with respect to volatile organic constituents. Samples should be collected directly into the
appropriate containers (see Standard Sample Containers, Appendix A). Also, refer to the Potable Water
Supply discussion in Section 2.8. All measurements for pH, specific conductance, temperature, and turbidity
should be recorded at the time of measurement.
7.3.3 Sampling Techniques -Wells without Plumbing
Following purging, samples should be collected using a peristaltic pump/vacuum jug assembly, a
Teflon®/stainless steel bladder pump, or a closed-top Teflon® bailer. These techniques are described
below.
Peristaltic pump/vacuum jug
The peristaltic pump/vacuum jug can be used for sample collection because it allows for sample
collection without the sample coming in contact with the pump tubing. This is accomplished by placing a
Teflon® transfer cap assembly onto the neck of a standard cleaned 4-liter (I-gallon) glass container.
Teflon® tubing (¼-inch O.D.) connects the container to both the pump and the sample source. The pump
creates a vacuum in the container, thereby drawing the sample into the container without it coming into
contact with the pump tubing.
Samples for volatile organic compound analysis should be collected using a bailer or by filling the
Teflon® tube, by one of two methods, and allowing it to drain into the sample vials. The tubing can be
momentarily attached to the pump to fill the tube with water. After the initial water is discharged through
the pump head, the tubing is quickly removed from the pump and a gloved thumb placed on the tubing to
stop the water from draining out. The tubing is then removed from the well and _the water allowed to drain
into the sample vials. Alternatively, the tubing can be lowered into the well the desired depth and a gloved
thumb placed over the end of the tubing. This method will capture the water contained in the tubing. It can
then be removed from the well and the water collected by draining the contents of the tubing into the sample
vials. Under no circumstances should the sample for volatile organic compound analysis be collected from
the content of any other previously filled container. A II equipment should be cleaned using the procedures
described in Appendix B. Also, refer to the Potable Water Supply discussion, Section 2.2, for additional
information.
Bladder Pumps
After purging has been accomplished with a bladder pump, the sample is obtained directly from the
pump discharge. If the discharge rate of the pump, during purging, is too great, so as to make sample
collection difficult, care should be taken to reduce the discharge rate at the onset of actual sample collection.
This is necessary to minimize sample disturbance, particularly with respect to samples collected for volatile
organic compounds analysis.

Bailers
When bailing, new plastic sheeting should be placed on the ground around each well to provide a
clean working area. The nylon rope should be attached to the bailer via a Teflon® coated stainless steel
wire. This coated wire is semi-permanently attached to the bailer and is decontaminated for reuse as the
bailer is cleaned. The bailer should be gently immersed in the top of the water column until just filled. At
this point, the bailer should be carefully removed and the contents emptied into the appropriate sample
containers.
7.3.4 Sample Preservation
Immediately after collection, all samples requmng preservation must be preserved with the
appropriate preservative. Consult Appendix A for the correct preservative for the particular analytes of
interest. All samples preserved using a pH adjustment (except VOCs) must be checked, using pH strips, to
ensure that they were adequately preserved. This is done by pouring a small volume of sample over the
strip. Do not place the strip in the sample.
7.3.5 Special Sample Collection Procedures
Trace Organic Compounds and Metals
Special sample handling procedures should be instituted when trace contaminant samples are being
collected. All sampling equipment, including pumps, bailers, water level measurement equipment, etc.,
which comes into contact with the water in the well must be cleaned in accordance with the cleaning
procedures described in Appendix B. Pumps should not be used for sampling, unless the interior and
exterior portions of the pump and the discharge hoses are thoroughly cleaned. Blank samples should be
collected to determine the adequacy of cleaning prior to collection of any sample using a pump.
Filtering
As a standard practice, ground water samples will not be filtered for routine analysis. Filtering will
usually only be performed to determine the fraction of major ions and trace metals passing the filter and used
for flow system analysis and for the purpose of geochemical speciation modeling. Filtration is not allowed
to correct for improperly designed or constructed monitoring wells, inappropriate sampling methods, or poor
sampling technique.
When samples are collected for routine analyses and are filtered, such as under conditions of
excessive turbidity, both filtered and non-filtered samples will be submitted for analyses. Samples for
organic compounds analysis should not be filtered. Prior to filtration of the ground water sample for
any reason other than geochemical speciation modeling, the following criteria must be demonstrated to
justify the use offiltered samples for inorganic analysis:
I.

EISOl'QAM
The monitoring wells, whether temporary or. permanent, have been constructed and
developed in accordance with Section 6.
The ground water samples were collected using sampling techniques in accordance with this
section, and the ground water samples were analyzed in accordance with US-EPA approved
methods.
"< 7-9 May 1996

Efforts have been undertaken to minimize any persistent sample turbidity problems. These
efforts may consist of the following:
• Redevelopment or re-installation of permanent ground water monitoring wells.
• Implementation of low flow/low stress purging and sampling techniques .
Turbidity measurements should be taken during purging and sampling to demonstrate
stabilization or lack thereof. These measurements should be documented in the field notes.
If the ground water sample appears to have either a chemically-induced elevated turbidity, such as
would occur with precipitate formation, or a naturally elevated colloid or fine, particulate-related turbidity,
filtration will not be allowed.
If filtration is necessary for purposes of geochemical modeling or other pre-approved cases, the
following procedures are suggested:
I.
2.
3.
Accomplish in-line filtration through the use of disposable, high capacity filter cartridges
(barrel-type) or membrane filters in an in-line filter apparatus. The high capacity, barrel-
type filter is preferred due to the higher surface area associated with this configuration. If a
membrane filter is utilized, a minimum diameter of 142 mm is suggested.
Use a 5 µm pore-size filter for the purpose of determining the colloidal constituent
concentrations. A 0.1 µm pore-size filter should be used to remove most non-dissolved
particles.
Rinse the cartridge or barrel-type filter with 500 milliliters of the solute (ground water to be
sampled) prior to collection of sample. If a membrane filter is used, rinse with 100
milliliters of solute prior to sample collection.
Potential differences could result from variations in filtration procedures used to process water
samples for the determination of trace element concentrations. A number of factors associated with filtration
can substantially alter "dissolved" trace element concentrations; these include filter pore size, filter type,
filter diameter, filtration method, volume of sample processed, suspended sediment concentration, suspended
sediment grain-size distribution, concentration of colloids and colloidally-associated trace elements, and
concentration of organic matter. Therefore, consistency is critical in the comparison of short-term and long-
term results. Further guidance on filtration may be obtained from the following: I) Metals in ground Water:
Sampling Artifacts and Reproducibility (3); 2) Filtration of Ground Water Samples for Metals Analysis (4);
and 3) Ground Water Sampling - A Workshop Summary (5).
Bacterial Sampling
Whenever wells (normally potable wells) are sampled for bacteriological parameters, care must be
taken to ensure the sterility of all sampling equipment and all other equipment entering the well. Further
information regarding bacteriological sampling is available in the following: I) Sampling for Organic
Chemicals and Microorganisms in the Subsurface (6); 2) Handbook for Evaluating Water Bacteriological
Laboratories (7); and 3) Microbiological Methods for Monitoring the Environment. Water and Wastes (8).

7.3.6 Specific Sampling Equipment Quality Assurance Techniques
All equipment used to collect ground water samples shall be cleaned as outlined in Appendix Band
repaired, if necessary, before being stored at the conclusion of field studies. Cleaning procedures utilized in
the field (Appendix 8), or field repairs shall be thoroughly documented in field records.
7.3.7 Auxiliary Data Collection
During ground water sample collection, it is important to record a variety of ground water related
data. Included in the category of auxiliary data are water level measurements, well volume determinations,
pumping rates during purging, and occasionally, drillers or boring logs. This information should be
documented in the field records. Well volume determinations are described in Section 7.2.1.
Water Level Measurements
Water table measurements from the top of the well casings (referenced to National Geodetic Vertical
Datum) in pennanent wells, and ground surface elevations in temporary wells should be made to assist in
determining the general direction of ground water flow and gradient. The methodology to be used to
determine well water levels are given in Section 15.8. Tracer dyes and radioactive and thermal detection
methods can be used to determine direction and velocities of flow (9). Also, a study of the general
topography and drainage patterns will generally indicate direction of ground water flow.
The ground surface elevation and top of casing elevation at the wells should be determined by stand-
ard engineering survey practices as outlined in Section 15.
Well Pumping Rate -Bucket/Stop Watch Method
The pumping rate for a pump can be determined by collecting the discharge from the pump in a
bucket of known volume and timing how long it takes to fill the bucket. The pumping rate should be in
gallons per minute. This method shall be used primarily with pumps with a constant pump rate, such as
gasoline-powered or electric submersible pumps. Care should be taken when using this method with some
battery-powered pumps. As the batteries' charge decreases, the pump rate also decreases so that pumping
rate calculations using initial, high pump rates may be erroneously high. If this method is used with battery-
powered pumps, the rate should be re-checked frequently to ensure accuracy of the pumping rate
calculations.

Expert flow and drawdown control
for low-volume purging
The MicroPurge basics'" MP10 Controller revolutionizes low-flow
sampling with advanced logic control of purge flow and well draw-
down. Simple up-down arrow keys increase and decrease purge flow,
driving a microprocessor to re-create expert techniques for low-flow
adjustment. Then, optimized settings are identified for recall in the
next round of sampling.
The MP10 also offers an easy way to prevent excessive monitoring
well drawdown during purging, by linking to the optional MP30
Drawdown/Water Level Meter.
The lightweight, compact MP10 sets the pace for a new generation
of genuine MicroPurge basics equipment, first in control and power for
low-flow sampling.

Automated purge stabilization
alert with powerful new
capabilities
The MicroPurge basics'" MP20 Flow Cell -from the leaders in low-flow
ground water sampling -sets new standards in performance, size and
price for purge water quality monitors. QED-exclusive PurgeScan'" technology
(U.S. Patent No. 6,415,659) signals when stabilization has been achieved for
selected water quality parameters, with automatic storage of key data points.
Two upgrades enhance performance even further. One option offers fast PC
download capability. The other option also adds a technology breakthrough tur-
bidity sensor in addition to pH, ORP, DO, temperature, and conductivity.
The lightweight, waterproof MP20 meter is simple to field calibrate. It dis-
plays all readings automatically. The sonde is a compact, low-profile design
with rugged, easy-to-service probes. The flow cell is designed to collect and
vent gas bubbles effectively, and to distribute purge flow evenly for quick mea-
surement response and more accurate readings.
The whole package is protected by a 3-year warranty, backed by service and
support from QED, the leader in low-flow sampling.

MICROPURGE' basics™ MP2O FLOW CELL
QED PurgeScan™ technology
assures stabilization
Successful, consistent low-flow sam-
pling is based on knowing when purge
water indicator parameters stabilize.
This allows sampling to begin only when
the pump discharges samples represen-
tative of the formation water.
Until now, deciding when stabilization
had been achieved was complex, requir-
ing you to monitor multiple parameters
and make repeated calculations. The
MP20 Flow Cell simplifies this process.
Microprocessor-based PurgeScan'"
technology performs the monitoring and
calculation, clearly signaling when stabi-
lization has occurred.
This makes low-flow sampling easy.
You can do it the right way, collecting
the most accurate samples, and saving
time and money.
Engineered for performance
and field readiness
The MP20 flow cell is engineered to
allow the probe to make rapid, accurate
responses to changes in purge water
parameters. The flow cell is 100%
transparent for observation. The low-vol-
ume, fast-response cell couples to the
sonde with a quick, bayonet attach-
ment, and can be used in either a hori-
zontal or vertical position.
The incoming flow is directed in a tan-
gential path around the flow cell to pro-
vide fast, thorough mixing with no "dead
spots" that could affect the accuracy of
purge parameter measurements.
Bubbles in the flow stream are vented
out of the cell and away from the probe
so they don't interfere with purge water
analysis.
The multiparameter probe has a spe-
cial sensor with built-in stirring for highly
stable dissolved oxygen readings. All
sensors are easy to calibrate and the
reference electrode is fully field-service-
able.
The large display screen makes it
easy to see your purging status. Power
by standard C cells keeps you on top of
the job all day with no energy supply
worries.

cell, meter, and calibration and storage
materials, in field-ready case.
