SUBJECT: Consideration of Personal Services Agreement for the Implementation of
the Workplan for Groundwater Monitoring Well Installation, (Ninyo &
Moore) and Appropriations of Funds.
RECOMMENDATION:
By motion,
1. Approve the Personal Services Agreement for the Implementation of the
Workplan for Groundwater Monitoring Well Installation, to include Monitoring
Well Installation, Performance of Monitoring, Testing and Reporting in the
amount of an additional $39,180; and,
2. Appropriate an additional $20,000 from the Water Reserve Fund for this work.
SITUATION:
Haley & Aldrich, Inc. (H&A) completed a site assessment and removal of three
underground fuel storage tanks on City owned property at Kinoshita Farm, in mid-June
2008. The report found Methyl Tertiary -Butyl Ether (MtBE) in the ground underneath
two of the tanks. The report prepared by H&A was submitted to the Orange County
Health Care Agency (OCHCA). OCHCA reviewed the report and asked the City to
prepare and submit to them a work plan and assessment of the impact of the MtBE
found under the two underground storage tanks. H&A completed the work plan and
submitted it to OCHCA for review and approval in late September 2008.
This work plan defined and explained the methods, procedures, and work that defined
the extent and scope of the MtBE in the ground. OCHCA largely accepted the work
plan as submitted, making some recommendations to delete minor components of work
on October 24, 2008. On November 18, 2008, the City Council approved a service
agreement with Environ Strategy Consultants, Inc. (ESCI) and they began work
immediately thereafter completing the site assessment work by December 12, 2008 and
submitted a draft report to OCHCA January 7, 2009. The findings of the report
recommended a departure from the work plan involving the removal of the
contaminated soil. OCHCA approved the soils removal plan on January 27, 2009; and
the soils removal work was completed by February 27, 2009. ESCI submitted a Soils
Excavation Report and a Work Plan for Groundwater Monitoring Well Installation of April

3, 2009. OCHCA approved the work plan with the addition of a fourth well, which was
accounted for in both proposals. Staff solicited proposals for completion of the work
plan. ECSI responded with a cost of $56,721. Ninyo & Moore proposed $39,180. Both
Haley and Aldrich, and Innovative Construction Services declined to make a proposal in
a cost competitive environment.
BACKGROUND:
The Kinoshita well tested positive for Methyl Tertiary -Butyl Ether (MtBE) in late January
2008, and its presence was confirmed in immediate follow-up tests. The well has been
off since that time. At the request of staff, PSOMAS conducted a database search for
potential sources of MtBE in the vicinity, and found references to the now removed fuel
storage tanks on the Kinoshita Farm site. After a ground survey and interviews with
persons knowledgeable in the history and uses of the farm, the presence of two and
possibly a third fuel storage tank was confirmed. These tanks are believed to have
been active in the time frame in which MtBE had been introduced into gasoline. The
firm of Haley & Aldrich Inc. was selected to perform the removal of the tanks and the
site assessment in June 2008.
FINANCIAL CONSIDERATIONS:
The fixed price proposals for the April 2009, Monitoring Well work plan were as follows:
• Environ Strategy Consultants Inc. $56,721
• Ninyo & Moore $39,180
• Haley and Aldrich, Inc. Declined to propose
• Innovative Construction Solutions Declined to propose
Staff recommends the approval of the Personal Services Agreement for the
Implementation of the Workplan for Groundwater Monitoring Well Installation, April 3,
2009, for Monitoring Well Installation, Performance of Monitoring, Testing and Reporting
in the amount of $39,180 with Ninyo & Moore; and, appropriation of an additional
$20,000 from the Water Reserve Fund for this work.
Below is a table of the overall expenditures for Contractors and Consultants to date,
related to the removal and remediation of the MtBE contamination at Kinoshita farms.
Additional costs may occur.

1.0 INTRODUCTION
Environ Strategy Consultants, Inc. (Environ Strategy), on behalf of the City of San Juan
Capistrano, is submitting this Workplan for Monitoring Well Installation (Workplan) for the
Kinosita Farm Site located at 32701 Alipaz Street, San Juan Capistrano, California (site, see
Figure 1). This Workplan was prepared based on recommendations made by the Orange County
Health Care Agency (OCHCA) in a meeting on January 16, 2009 and letter dated January 27,
2009 (Appendix A). Specifically, groundwater samples collected at the former location of UST
No. I contained detectible levels of dissolved -phase fuel constituents. Consequently, it was
recommended that groundwater monitoring wells be installed to define the extent of
hydrocarbon -impacted groundwater in the vicinity of former UST No. 1.
Three groundwater monitoring wells are proposed to be installed in the vicinityof former UST
No. 1, in an effort to define the extent of dissolved -phase contamination identified during site
assessment activities. The wells will be sampled on a quarterly basis to monitor groundwater
conditions beneath the site. The following sections provide a description of the site and a
summary of the site geology and hydrogeology, followed by a description of the proposed scope
of work.
2.0 SITE DESCRIPTION AND BACKGROUND
The site address is 32701 Alipaz Street, San Juan Capistrano, California and is currently owned
by the city of San Juan Capistrano. The site has been an active farm since the 1930s. Three
USTs were removed from the site on June 6, 2008. The city of San Juan Capistrano has a water
production well on the east side of Alipaz Street, southeast of the site. The site layout is shown
in Figure 2.
2.1 UST Removal and Site Assessment Activities
On June 6, 2008, three USTs (UST No. 1, UST No. 2, and UST No.3) were removed from the
site. The locations of the former USTs are shown'on Figure 2. Hydrocarbon -impacted soil was
encountered beneath USTs No. I and No. 3. Based on the soil analytical results, additional
subsurface site assessment was performed in the vicinity USTs No. 1 and No. 3, as well as across
the site.
From December 4 through 17 2008, thirty-one direct push soil borings were advanced at the site.
The soil boring locations are shown on Figure 2. A total of 56 soil samples were collected from
beneath and in the vicinity of USTs No. 1 and No. 3 and 56 groundwater samples collected from
beneath the USTs and across the site. Soil samples were collected at approximately five-foot
intervals to 40 feet below ground surface (bgs) beneath USTs No. I and No. 3, and to 25 feet bgs
in the immediate vicinity of the USTs. Groundwater samples were collected from the borings
beneath the USTs at approximately 25 feet and 45 feet bgs. Hydrocarbon -impacted soil was
encountered directly beneath, and in the immediate vicinity of USTs No. t and No. 3.

Dissolved -phase hydrocarbons were encountered in one groundwater grab sample beneath UST
No. I at 25 feet bgs. Based on the findings and analytical results of the subsurface assessment,
the extent of hydrocarbon -impacted soil and groundwater appears to be localized to the area
directly beneath the former location of UST No. 1. Additional details regarding the site
assessment activities is presented in the Site Assessment Report, dated March 30, 2009.
In February 2009 and in accordance with the OCHCA-approved Excavation Workplan for Soil
Removal, additional soil excavation was performed in the area of Former UST No. 1. Soil was
excavated to a depth of approximately 25 feet bgs. A total of 670.47 tons of soil was transported
under manifest to an offsite disposal/recycling facility. Under the direction of an OCHCA
inspector, nine confirmation soil samples were collected from the former UST cavity bottom and
sidewalls. Petroleum hydrocarbons and volatile organic compounds (VOCs) were not detected
in the confirmation soil samples, with the exception of tert-amyl methyl ether (TAME) which
was detected in sample UST-I-BFE-4 [0.85J micrograms per kilogram (ug/kg)).
A minor amount of groundwater seepage was observed while the excavation was open.
Approximately 900, gallons of water were pumped from the bottom of the excavation prior to
backfilling. One groundwater grab sample was collected from the water in the excavation had
detectable concentration of TPHg at 32 ug/L. Field activities, observations and results associated
with the excavation activities are summarized in the Excavation Report, dated April 3, 2009.
Based on site assessment findings, the OCHCA recommended the installation of three
groundwater monitoring wells in the vicinity of former UST No. 1.
3.0 GEOLOGY AND HYDROGEOLOGY
The following sections provide brief descriptions of the regional and site geology and
hydrogeology.
3.1 Regional and Site Geology
The site is located within the floodplain of the Trabuco Creek in the northern Peninsular Range
of southern Orange County. The floodplain extends approximately 2 miles across and is
bounded by the San Joaquin Hills approximately 0.8 miles to the west and the foothills of the
Santa Ana Mountains approximately 1 mile to the east of the site. The Christianitos Fault Zone
is located approximately 3 miles east of the site, and the confluence of Trabuco Creek and San
,Tuan Creek is approximately 0.5 mile east of the site.
The San Juan Capistrano area is underlain by Tertiary -age sedimentary rocks that are folded in a
broad synclinal trough with at north -trending axis. The site is within the central portion of the
syncline that is underlain by primarily marine siltstone and sandstone of the Capistrano
Formation of late Miocene and early Pliocene age. In the vicinity of the site, the Capistrano
Formation is capped unconformably by a thin sequence or nonmarine Pleistocene and Recent age
alluvial sediments associated with Trabuco Creek.

Son Juan Capistrano California April 3 2009
Soils observed during the drilling at the site consist of interbedded fine-grained silt and clay
layers to depths ranging from 10 to 30 feet bgs, with silty sand and sand layers present below this
to the maximum depth explored of 68 feet bgs.
3.2 Regional and Site Hydrogeology
The site is located within the lower Trabuco Creek Division of the San Juan Groundwater Basin,
defined as the area downgradient of the confluence of Oso and Trabuco Creeks. The San Juan
Groundwater basin underlies the San Juan Valley and several tributary valleys in southern
Orange County, The primary water -bearing layer within the basin is the Quaternary alluvium.
This alluvium is generally composed of a heterogeneous mixture of clay, silt, sand and gravel
ranging in thickness from 65 to 125 feet. Groundwater within the basin typically flows
southwest toward the Pacific Ocean. Recharge within the basin occurs from the San Juan Creek,
Oso Creek, and Trabuco Creek watersheds.
Groundwater was generally encountered in the direct -push soil borings at depths of
approximately 20, 40, and 60 feet bgs. Based on a subsequent excavation at the former UST
No. 1 location, the groundwater at approximately 20 feet bgs appeared to be perched water
directly above a clay layer. There was minor seepage from this cone into the excavation.
4.0 PROPOSED SCOPE OF WORK
Three groundwater monitoring wells are proposed to be installed in the immediate vicinity of the
former UST No. I excavation area to define the extent of hydrocarbon -affected groundwater.
The proposed well locations are shown on Figure 3. The following sections summarize the field
activities and schedule anticipated to complete the proposed scope of work. Additional details
regarding Environ Strategy's general field practices and procedures are provided in Appendix B.
4.1 Permitting, Access and Notifications
Before initiating field activities, the necessary soil boring/well permits will be secured as
required by State and local agencies.
Boring locations will be pre -marked in white spray paint and Underground Services Alert
notified a minimum of 72 hours in advance to locate potential underground utilities servicing the
work areas. Similarly, the OCHCA will be notified a minimum of 72 hours prior to conducting
field activities.
4.2 Health and Safety
Field work will be conducted in accordance with a Site Specific Health and Safety Plan (HASP).
Before commencing field activities, a daily "tailgate" health and safety meeting will be
conducted with Environ Strategy personnel and contracted employees. Additionally, a task
safety analysis (TSA) will be performed and reviewed prior to commencing field activities to
further identify and mitigate potential hazards associated with the proposed scope of work. At a
environ, strategy consultants, inc.es

minimum, the HASP and TSA will be reviewed to address potential physical, chemical,
mechanical, and biological hazards associated with the proposed scope of work.
4.3 Drilling and Soil Sampling
A drilling contractor with a C-57 contractor's license will be retained to provide drilling and soil
sampling services. The well borings will be drilled to a depth of approximately 35 feet bgs at the
selected locations shown in Figure 3. Prior to drilling, each boring location will be cleared of
subsurface utilities using a hand -auger to an approximate depth of 5 feet. If utilities are
encountered, the pilot hole will be abandoned, relocated and cleared. Well borings will be
advanced using a truck mounted hollow -stem auger drill rig.
Soil samples will be collected from the borings at a minimum of 5 -foot intervals and where
lithologic changes and/or petroleum hydrocarbons are suspected. The sampling will be
performed using a split -spoon drive sampler fitted with three 6 -inch long sampler rings. Soil
collected in the lowest (deepest) of the three rings will be submitted for laboratory analyses.
Each sample will be immediately sealed, labeled, placed on ice in a cooler, and delivered to a
state -certified, analytical laboratory under chain -of -custody procedures.
Soil collected from each sample interval will be used to describe subsurface lithology in
accordance with the Unified Soil Classification System by a field geologist working under the
direction of a licensed California Professional Geologist. Additionally, collected soil will be
field -screened using a photionization detector (PID) to measure the soil headspace for potential
volatile compounds. Sample IDs, lithologic descriptions, blow counts and PID readings will be
recorded on the soil boring logs.
Down -hole drilling equipment will be steam -cleaned within a self-contained decontamination
trailer. Soil sampling equipment will also be cleaned in between each use in a soapy wash with a
laboratory -grade detergent and triple rinsed. Tools and sampling equipment will be allowed to
dry prior to use.
4.4 Well Installation
As previously mentioned, the well borings will be drilled to a depth of approximately 35 feet.
The wells will be constructed with 4 -inch -diameter, flush threaded, schedule -40 polyvinyl
chloride (PVC) casing and factory -slotted (0.01 -inch slot) screen. A total of 15 feet of screen
will be installed in each well and extend approximately 5 feet above and 10 feet below the
groundwater table elevation encountered during drilling. However, final well construction
details may change based on subsurface conditions encountered during drilling. Additionally,
wells will not extend through laterally extensive impermeable zones that are below the water
table and that are at least five feet thick. If this situation is encountered, the well will be
terminated one to two feet into the impenneable zone. The drilling and well installation
activities will be conducted in accordance with California Well Standards presented in the
Department of Water Resources (DWR) Bulletins 74-81 and 74-90
The annular space surrounding the screen interval will be backfilled with 2112 sand or equivalent
environ strategy consultants, inc.f

to a minimum of 2 feet above the top of the screen. The sand sized will be adjusted if necessary
based on observed field conditions. To settle the filter pack, the well will be surged prior to the
placement of the well seal. The sandpack will be sealed with a minimum of 3 feet of hydrated
bentonite chips. Volclay grout or bentonite will be used to seal the remaining annular interval.
Each well will be completed at the surface with a flush mount, traffic -rated, 12 -inch diameter
well box set in concrete.
To improve hydraulic communication between the aquifer and the well, each monitoring well
will be developed, purged, and sampled in accordance with State and local guidance. The
monitoring wells will be surveyed to a known benchmark before sampling.
4.5 Groundwater Monitoring
The wells will be monitored and sampled quarterly for four quarters. Groundwater monitoring
well gauging, purging, and sampling will be conducted in accordance with the monitoring well
sampling protocols as described in Environ Strategy's general field procedures .(see
Appendix B).
4.6 Laboratory Analysis
Soil and groundwater samples will be submitted to a California state -certified environmental
laboratory under chain -of -custody procedure. Soil and groundwater samples will be analyzed for
TPHg by EPA Method 8015B and for VOCs including BTEX and the fuel oxygenates (MTBE,
DIPS, ETBE, TBA, TAME) using EPA Method 8260B, full scan.
4.7 Waste Management
Soil cuttings and decontamination liquid generated during well installation activities will be
contained in Department of Transportation (DOT) -approved, 55 -gallon drums. Each drum will
be sealed, labeled, and staged in a secure location on the subject site pending characterization
and disposal. Waste materials will be transported offsite to an appropriate disposal/recycling
facility under manifest. Copies of the manifests documenting the transportation and disposal of
the waste material will be presented in the well installation report.
4.8 Report Preparation
Upon completion of the field activities, a report will be prepared summarizing the field activities,
observations and findings associated with the installation of the wells and will include supporting
documentation (permits, boring and well construction logs, laboratory reports and manifests).
Additionally, the groundwater monitoring data and analytical results will be tabulated and
presented in a summary report to be submitted on a quarterly basis. The reports will be
transmitted to the City of San Juan Capistrano and the OCHCA.

Subject: Site Progress Report for Subsurface Investigation dated January 6, 2009
prepared by Environ Strategy Consultants, Inc.
Re: Kinoshita Farm Site
32701 Alipaz Street
San Juan Capistrano, CA
OCHCA Case #08UT008
Dear Mr. Bauman:
The Orange County Local Oversight Program (OCLOP) has reviewed the subject report that
documents the preliminary results from the recent subsurface investigation performed in December
2008. Direct -push soil borings were drilled to collect soil and groundwater samples beneath the
former underground storage tanks (USTs) and to collect groundwater samples .at discrete depths
across the referenced site. Based on the Agency's review of the results and discussions with you
and your consultant at a meeting held at this office on January 16, 2009, the OCLOP has the
following comments:
MTBE and TBA contamination was detected in soil and groundwater in the boring drilled
within the center of the former UST# I . Based on the detection of MTBE/TBA, the OCLOP
requires you to install a minimum of three (3) shallow groundwater monitoring wells in the
vicinity of UST#1 to delineate the lateral extent of the groundwater contamination. Please
submit a workplan for monitoring well installation within 30 days of your receipt of this
letter.
2. The report recommends performing limited soil excavation around UST#I to remove any
residual fuel hydrocarbons. This Agency has no objections to the proposed excavation. If
the City decides to proceed with the excavation, a remedial action plan must be submitted to
the OCLOP for review and concurrence.
Eric P. Bauman
January 23, 2009
Page 2
3. A final consolidated subsurface assessment report documenting the results of the
investigation with boring logs and lab analytical data must be submitted to the OCLOP.
This report may be submitted along with the forthcoming workplan, or as a separate report.
4. The California Code of Regulations, Title 23, Division 3, Chapter 30 and Title 27, Division
3, Subdivisions i & 2 require individuals submitting compliance reports for underground
storage tank systems to submit data over the internet to the State Water Resources Control
Board (SWRCB) Geotracker system. Please note that all required data submittals must be
uploaded to the Geotracker when submitting the site assessment report to the OCLUST (soil
and groundwater data, boring logs, site map, and Geo -Reports).
Please note that groundwater monitoring wells are required to be installed at the site due to the
sensitivity of this case because of the site's proximity to an active production well that is less than
500 feet distance from the source area and has been impacted by MTBE contamination.
If you have any questions, please contact me at (714) 433-6262 or Anthony Martinez at (714) 433-
6260.

GENERAL FIELD PRACTICES AND PROCEDURES
0 0
GENERAL FIELD PROCEDURES
General procedures used by Environ Strategy Consultants, Inc. (Environ Strategy) in site
assessments for drilling exploratory borings, collecting samples, and installing
monitoring wells are described herein. Environ Strategy's groundwater monitoring and
sampling protocols are also described. The general procedures may be modified as
appropriate based on site conditions. A California Professional state -registered geologist
supervises the following procedures.
PRE -FIELD WORK ACTIVITIES
Health and Safety Plan
Field work performed by Environ Strategy at the site is conducted according to
guidelines established in a Site Health and Safety Plan (HASP). The HASP is a
document that describes the hazards that may be encountered in the field and specifies
protective equipment, work procedures, and emergency information. A copy of the
HASP is at the site and available for reference by appropriate parties during field work.
Locating Underground Utilities
Before commencement of subsurface work, the location of the excavation, boring, etc., is
marked with white spray paint as required by law. An underground locating service such
as Dig -Alert or Underground Service Alert (USA) is contacted 72 -hours before initiating
field work. The locating company contacts the owners of the various utilities in the
vicinity of the site to mark the locations of their underground utilities. Invasive work is
preceded by hand augering to a minimum depth of five feet below surface grade to avoid
contacting potential underground utilities.
FIELD METHODS AND PROCEDURES
Exploratory Soil Borings
Soil borings will be drilled using a truck -mounted, hollow stem auger (HSA) drill rig or
using hydraulically actuated "direct -push" and percussion equipment, e.g. Geoprobe°. If
14SA drilling techniques are utilized, soil samples for logging will be obtained from
auger -return materials and by advancing a modified California split -spoon sampler
equipped with stainless steel liners or equivalent into undisturbed soil beyond the tip of
the auger. Similarly, if direct -push technology (DPT) is used, soil samples will be
retrieved from the borings using a 3 -foot -long, 2 -inch diameter continuous -core split -
barrel sampler lined with six stainless steel/brass sleeves or a 4 -foot -long acetate liner.
Soils will be logged by a geologist according to the Unified Soil Classification System
using standard geological techniques. Drill cuttings will be screened using a portable
Environ Strategy Page 2 of 7
General Field Practices and Procedures
photoionization detector (PID) or a flame ionization detector (FID). Exploratory soil
borings not used for monitoring well installation will be backfilled to the surface with
bentonite -cement slurry and/or hydrated bentonite chips and capped at the surface to
match surrounding conditions.
Soil Sample Collection
Auger Samplin 7: During drilling, soil samples will be collected in clean steel brass, two
by six inch tubes. The tubes will be set in an 18 -inch -long split -barrel sampler. The
sampler will be conveyed to the bottom of the borehole attached to a wire -line hammer
device on the drill rig. When possible, the split -barrel sampler will be driven its entire
length, either hydraulically or by repeatedly pounding a 140 -pound hammer using a 30 -
inch drop. The number of drops (blows) used to drive the sampler will be recorded on
the boring log. The sampler will be extracted from the borehole, and the tubes containing
the soil samples will be removed. Upon removal, the ends of the lowermost tube will be
sealed with Teflon sheets and plastic caps. Soil samples for chemical analysis will be
labeled, placed on ice, and delivered to a state -certified analytical laboratory, along with
the appropriate chain -of -custody documentation.
Geoprobe Samnline: The push -probe system is driven by a hydraulic hammer or
vibrator. Each boring will be sampled at a minimum of 5 -foot intervals. Shorter
sampling intervals or continuous core sampling techniques may be employed to provide
subsurface definition. As the core barrel is advanced, soil is driven into an inner 1'/a -
inch diameter core barrel, which is either lined with steelibrass or acetate sleeves. After
being driven 5 feet, the rods are removed from the borehole. Upon removal, the ends of
the lowermost sleeve will be sealed with Teflon sheets and plastic caps. Soil samples for
chemical analysis will be labeled, placed on ice, and delivered to a state -certified
analytical laboratory, along with the appropriate chain -of -custody documentation.
Soil Classification
As the samples are obtained in the field, they will be classified by the field geologist in
accordance with the Unified Soil Classification System. Representative portions of the
samples will be retained for further examination and for verification of the field
classification. Logs of the borings indicating the depth and identification of the various
strata and pertinent information regarding the method of maintaining and advancing the
borehole will be prepared. Specifically, for each sampling interval, field estimates of
soil type, density/consistency, plasticity, grading, moisture, color, and any other
pertinent information will be recorded on the boring log.
Soil Sample Screening and Sampling
Soil samples selected for chemical analysis will be determined from a headspace
analysis using a PID or an FID. The soil will be placed in a Ziploc® bag, sealed, and
0
Environ Strategy
General Field Practices and Procedures

allowed to reach ambient temperature, at which time the PID probe will be inserted into
the Ziploc bag. The total volatile hydrocarbons present are detected in parts per million
(ppm). The PID will be calibrated daily to an isobutylene standard. Additionally, a water
trap will be fixed to the end of the PID sampling wand to minimize potential interference
from entrained soil moisture.
Generally two soil samples from each soil boring will be submitted for chemical analysis
unless otherwise specified in the scope of work (See applicable workplan or the client's
specified scope of work). Soil samples selected for analysis typically represent the
boring bottom sample or the sample just above the first -occurrence of groundwater and
sample that exhibits the highest PID reading.
HydroPunch® Sampling
A grab groundwater sample is collected using a Hydropuncho sampling device. The
hydropunch can be used with either a HSA drill or DPT rig. The hydropunch consists of
a stainless steel probe, which is advanced in to the water -yielding zone then withdrawn
to expose an internal screen. Once the probe is opened, groundwater enters while soil
particles larger than silt are prevented from entering by a screen. A decontaminated
stainless steel bailer or equivalent is inserted down the center of the well screen to obtain
a "grab -type" groundwater sample for analysis. The samples are carefully transferred
from the bailer to zero headspace, 40 milliliter glass vials fitted with Teflon -lined caps.
The groundwater sample is labeled, placed on ice (i.e. chilled at approximately 4 degrees
Celsius), and delivered to a state -certified analytical laboratory, along with the
appropriate chain -of -custody documentation. The boring is backfilled with a
cement/bentonite slurry and capped at the surface to match surface conditions.
Chain -of -Custody Protocol
Chain -of -Custody protocol is followed for all soil and groundwater samples selected for
laboratory analysis. The Chain -of -Custody form(s) accompanies the samples to the
laboratory and provides a continuous record of possession at all times.
Decontamination
Drill cuttings generated during the drilling procedure will be contained in labeled and
marked, DOT -approved 55 -gallon drums and placed in a secured onsite location.
Drilling equipment is decontaminated by steam cleaning before being brought onsite.
The augers are also steam cleaned before proceeding with each new. Before use, the
sampler and sampling sleeves are brushed -scrubbed in a Liqui-nox and potable water
solution and rinsed twice in clean potable water. Sampling equipment and sleeves are
also decontaminated before each sample is collected to avoid cross -contamination
between borings.
Environ Strategy Page 4 of 7
General FieldPracticesand Procedures
Monitoring Well installation
Monitoring wells will be completed by installing 2 -to 6 -inch diameter Schedule 40
Polyvinyl chloride (PVC) casing. The borehole diameter for a monitoring well will be a
minimum of four inches larger than the outside diameter of the casing. The 2 -inch
diameter flush -threaded casing is generally used for wells dedicated for groundwater
monitoring purposes.
A monitoring well is typically cased with threaded, factory -perforated and blank
Schedule 40 PVC. The perforated interval consists of slotted casing, generally with 0.01 -
or 0.02 -inch -wide by 1.5 -inch long slots, with 42 slots per foot. The screened sections of
casing are factory -machine slotted and will be installed approximately 5 feet above and
10 feet below first -encountered water level. The screened interval will allow for seasonal
fluctuation in water level and for monitoring potential floating product. A threaded or
slip PVC cap is secured to the bottom of the casing, The slip cap can be secured with
stainless steel screws or friction; no solvents or cements are used. Centering devices may
be fastened to the casing to ensure even distribution of filter material and grout within
the borehole annulus. The well casing is thoroughly washed and/or steam cleaned, or
may be purchased as pre -cleaned, prior to completion.
A filter pack of graded sand will be placed in the annular space between the PVC casing
and the borehole wall. Sand will be added to the borehole through the hollow stem of the
augers to provide a uniform filter pack around the casing and to stabilize the borehole.
The sand pack will be placed to a maximum of 2 feet above the screens, followed by a
minimum 3 -foot seal consisting of hydrated bentonite pellets.
Cement grout containing 5 percent bentonite or concrete will be placed above the
bentonite seal to the ground surface. A concrete traffic -rated vault box will be installed
over the monitoring well(s). A watertight locking cap will be installed over the top of the
well casing. Reference elevations for each monitoring well will be surveyed when more
than two wells will be located on site. Monitoring well elevations will be surveyed by a
California -licensed surveyor to the nearest 0.01 -foot relative to mean sea level (MSL).
Horizontal coordinates of the wells will also be measured.
Exploratory boring logs and well construction details will be prepared for the final
written report.
Monitoring Well Development
After groundwater monitoring wells are installed, each well is developed using a surge
block and bailer (or submersible pump) to remove suspended solids and until the water
quality parameters stabilize, which consist of conductivity, pH, and temperature. If the
well is bailed or pumped dry during the development process, recharge rates are
recorded. Neither water nor chemicals are introduced into the monitoring wells during
0

development. All development water is contained in drums and place in a secured onsite
location.
Waste Management
Soil cuttings, decontamination and/or development water will be contained in DOT -
approved, 55 -gallon drums. Each drum will be appropriately labeled, marked and
temporarily stored in a secured onsite location pending waste characterization. Upon
receipt of analytical results, contained waste will be transported offsite to an appropriate
disposal/recycling facility.
MONITORING WELL SAMPLING PROTOCOL
The groundwater sampling procedures used by Environ Strategy are designed to comply
with local regulatory guidance and reflect the current professional standards and
practices employed in the industry. A description of the groundwater sampling
procedures is provided below.
Well Gauging
Initial site activities include determination of well locations based on a current site map.
The area around each well is inspected to ensure that it is free of debris that could
potentially fall into the well. A clean plastic trash bag or a piece of visqueen plastic
sheeting is placed adjacent to the well to stage sampling equipment and supplies.
Indications of well or well box damage are noted on appropriate field forms.
Prior to sampling, the construction details of each groundwater monitoring well to be
sampled are reviewed to establish their respective depths and the length and placement
of their screened intervals.
When the well is opened, the Technician will immediately measure the concentration of
volatile organic vapors in the upper portion of the well casing with a photo -ionization
detector (PID) calibrated to hexane. This measurement will guide the selection of
respiratory protection equipment for sampling (as dictated by Environ Strategy's Health
and Safety Plan) at that particular well. Historical air monitoring data should also be
referred to when selecting appropriate respiratory protection.
Prior to purging or sampling, initial static water levels are measured and recorded for all
site wells. Depth to groundwater measurements accurate to 0.01 feet are obtained with
an electronic sounding instrument that can also distinguish between liquid phase
hydrocarbon (LPH) and water. The depths to LPH (if present), to water, and to the
bottom of the well are measured from the top of the well casing (surveyors mark or
notch if present). These measurements and the approximate thickness of potential LPH
are recorded on the Fluid Level Measurement Form. Field forms are included in the
Environ Strategy Page 6 of 7
General Field Practices and Procedures
Groundwater Monitoring Report as an Appendix.
As the measuring device is removed, it is thoroughly washed with a Liqui-nox/ water
mixture and rinsed with distilled water. The tape is wiped dry with a paper towel as it is
re -wound.
Note, wells that are found to contain LPH are not purged or sampled.
Well Purging
If purging is required, depth to groundwater measurements and well construction details
are used to calculate the volume of water within each well casing.
During purging, the water quality parameters consisting of temperature, pH,
conductivity, and turbidity are monitored as each well volume is removed. In some
cases, additional water quality parameters, such as dissolved oxygen (DO) and
oxidation-reduction potential (ORP), are also measured during purging. Purging
continues until these parameters vary less than 10 percent from the previous reading,
three well volumes are removed, or 80 percent of the well volume has been removed
with no significant well recharge. Groundwater samples are collected without additional
purging if the volume of groundwater in a well does not recover to at least 80 percent of
its initial pre -purge measurement within two hours.
Depth to groundwater measurements, purge volumes, and water quality parameters
obtained as each well is purged are recorded on Groundwater Monitoring Field Forms.
Instruments used for groundwater parameter measurements are calibrated daily in
accordance with the manufacturer's instructions.
Purge water is generally collected in labeled 55 -gallon, DOT -approved drums for
disposal. Drums may be left on site in a secure location for disposal by others, or
transported to a collection location for eventual transfer. to a licensed treatment or
recycling facility. In some cases, purge water is collected directly from the site by a
licensed vacuum truck company, or treated on site by an active remediation system.
Groundwater Sampling
After wells are purged, or not purged, according to agency -approved
instructions/guidelines, groundwater samples are collected for laboratory analysis.
Groundwater samples will be collected from each well using a '/z -inch to 3 -inch -diameter
disposable polyethylene bottom -filling bailer which is lowered just below the water
table. Groundwater brought to the surface is transferred from the bailer into appropriate
laboratory prepared containers for each required analysis. After filling, sample
containers are immediately capped. Particular care is given to containers for volatile
organic analysis (VOAs), which require filling to zero headspace and fitting with Teflon -
sealed caps.

Page 7 of 7
Each sample container is labeled with the project number (or site ID), well designation,
sample date, and the samplers initials, and then immediately sealed in a zip lock bag and
placed in a pre -chilled, insulated chest with ice. Samples remain chilled prior to and
during transport to a state -certified laboratory for analysis. Sample container description
and requested analyses are entered onto a chain -of -custody form to provide instruction
for the laboratory. The chain -of -custody form accompanies the samples during
transportation to provide a continuous record of possession from the field to the
laboratory. If a freight or overnight carrier transports the samples, the carrier is noted on
the form along with the package tracking number.
For wells that are connected to a treatment system, samples are taken from the sample
ports of actively pumping remediation wells.
Sequence of Gauging, Purging, and Sampling
The sequence in which monitoring activities are conducted is determined on a site-
specific basis. In general, wells are gauged beginning with the least -affected well and
ending with the well that has the highest contaminant concentration based on previous
analytical results. After gauging is completed, wells are purged and/or sampled in the
order of least -affected to most -affected wells.
Field QA/QC Procedures
A trip blank field sample is used to ensure that sample collection and handling
procedures do not introduce contaminants into the groundwater samples. The trip blank
is prepared by filling sample containers in the field with de -ionized water. The sample
containers are labeled as "Trip Blank," placed in the cooler with other groundwater
samples, and transported to the laboratory for analysis.
Decontamination
To reduce the potential for cross -contamination between wells, strict isolation and
decontamination procedures are observed. Portable pumps are not used in wells with
LPH. Technicians wear nitrile gloves during all gauging, purging and sampling
activities. Gloves are changed between wells and more often if warranted. Any
equipment that may come in contact with fluids is either dedicated to a particular well,
decontaminated prior to each use, or discarded after a single use. Decontamination
consists of a four -stage decontamination process: a phosphate -free detergent (Liqui-nox)
wash, a double potable -water rinse, and a final deionized water rinse.
Exceptions
Additional tasks or non-standard procedures that may be requested or required for a
particular site are documented on the appropriate field notes/forms.

Dear Mr. Bauman:
Ninyo & Moore is pleased to submit this cost estimate to install four groundwater monitoring
wells and conduct four quarterly groundwater monitoring and sampling events at the above -
referenced property (site). The work is being conducted in general accordance with the Work-
plan for Groundwater Monitoring Well Installation by Environ Strategy Consultants Inc. dated
April 3, 2009 to assess groundwater at the site as required by the Orange County Health Care
Agency (OCHCA).
SCOPE OF SERVICES
The following paragraphs present the scope of services, fee, and schedule for installing, devel-
oping, and monitoring and sampling the wells. The work will be performed in accordance with
the OCHCA approved work plan.
Task 1 — Obtain Regulatory Permits
Ninyo & Moore will obtain well construction permits from OCHCA.
Task 2 — Site Specific Health and Safety Plan
Ninyo & Moore will prepare a site specific health and safety plan to identify worker safety
issues during the field work.

Task 3 — Boring Mark -Out
April 23, 2009
Proposal No. P-14102
Prior to the well installation, Ninyo & Moore will mark proposed locations for the groundwa-
ter monitoring wells with white paint, notify Underground Service Alert (USA), and request
that they delineate the locations of underground utilities near the proposed drilling locations.
Task 4 — Install, Develop, and Survey Four Groundwater Monitoring Wells
Four boreholes will be advanced using a hollow -stem auger drilling rig to depths of up to 35
feet below ground surface (bgs). The wells will be constructed of 4 -inch -diameter polyvinyl
chloride (PVC) casing. The screened interval of the wells will extend approximately 10 feet
below the measured groundwater depth and approximately 5 feet above the measured
groundwater depth and will consist of 0.010 -inch slotted PVC casing.
Soil cuttings from the wellbores will be collected at every 5 feet and logged according to the
Unified Soil Classification System (USCS) under direction of a California licensed profes-
sional geologist. Up to 12 soil samples will be analyzed for total petroleum hydrocarbons as
gasoline (TPHg) and for benzene, toluene, ethylbenzene, and total xylenes (BTEX) plus
fuel oxygenates in general accordance with United States Environmental Protection Agency
(EPA) Methods 8015M and 8260B, respectively. After at least 72 -hours after well installa-
tion, each well will be developed using the surge and bail technique. The well casings will
be surveyed by a State -licensed surveyor in accordance with the requirements of the State
of California Water Resources Control Board (SWRCB) for uploading to the SWRCB Geo -
Tracker database.
Task 5 — Quarterly Groundwater Monitoring and Sampling (4 events)
At least 48 -hours after development of the proposed wells, Ninyo & Moore will conduct the
first event of groundwater monitoring and sampling for the four wells. The wells will be
monitored for depth to groundwater and the presence of free product. The groundwater
samples will be collected using the purge method and will be analyzed for TPHg and for
BTEX plus fuel oxygenates in general accordance with EPA Methods 8015M and 8260B,
respectively. Three additional events of monitoring and sampling will be conducted as de-
scribed above on a quarterly basis.

Task 6 — Disposal
• April 23, 2009
Proposal No. P-14102
Up to twenty-six 55 -gallon drums of soil cuttings, decontamination water, and groundwater
are estimated to be generated during the installation, development, and first round of sam-
pling of the monitoring wells. Up to 4 drums of groundwater are estimated to be generated
per quarter for each quarterly groundwater sampling event. Following receipt of each event
of laboratory results, the drums will be transported to a recycling facility as non -hazardous
waste. If characterization of the waste indicates the material is hazardous, additional
charges will apply.
Task 7 — Well Installation Report
Following the well installation activities, a report will be provided to the City of San Juan
Capistrano and OCHCA outlining the activities and sampling results. The first event of
groundwater monitoring and sampling will be included in this report.
Task 8 — Groundwater Monitoring Report (3 Reports)
Following each subsequent round of groundwater monitoring and sampling, a report will be
provided to the City of San Juan Capistrano and OCHCA outlining the activities and sam-
pling results.
ASSUMPTIONS
