Two soil borings will be advanced to a total depth of 50 feet below.ground surface (bgs)
and four shallow soil borings will be advanced to a total depth of 5-feet bgs within the
sludge drying bed. Deep soil samples will be collected at 0.5, 2, 5, 10, 20, 30, 40, and 50
feet bgs (i.e., 16 total samples) and observed geologic conditions will be logged. Samples
will be collected from 0.5, 2, and 5-feet bgs at each of the shallow soil sampling locations
(i.e., 12 total shallow soil samples). A total of three field duplicate samples will be
collected.
I:\cmo\Agreements\Rincon Consultants, Inc. (Landfill Leachate Enviromnental Site Assessment) FY2526-016.docx-ms
Soil samples will be collected using United States Environmental Protection Agency
(EPA) Method 5035, placed into volatile organic analysis glass vials, and submitted to
the analytical laboratory to be analyzed for VOCs. All other soil samples will be placed
in the laboratory supplied sampling containers specific to the requested laboratory
analytical method, as described in the revised Work Plan. The soil boring locations will
be recorded using a portable GPS receiver capable of submeter accuracy.
Task 2.2 Discharge Area Soil Sampling Laboratory Analytical
The soil samples collected from the sludge drying bed (i.e., 28 total soil samples plus
three field blank samples) will be analyzed for the following constituents:
• Title 22 Metals by EPA Method 6010B/7470A/7471A
• Volatile organic compounds (VOCs) by EPA Method 8260E
• Semi -volatile organic compounds (SVOCs) by EPA Method 8270C
• Chlorinated pesticides by EPA Method 8081

• Perchlorate by EPA Method 314.0
• Per- and polyfluoroalkyl substances (PFAS) by Department of Defense (DoD) Quality
Systems Manual (QSM) Version 5.1 or later.
Task 3 Groundwater Monitoring Well Installation, Sampling, and Laboratory Analytical
Task 3.1 Drilling Oversight
In accordance with the revised Work Plan, Consultant proposes to oversee the installation
of a total of one groundwater monitoring well at the Wastewater Treatment Plant
(WWTP) adjacent to the sludge drying bed (MW-01). The groundwater monitoring well
will be installed using a sonic drill rig to an estimated target total depth of 250 feet below
grade. If a sonic drill rig is not available when subsurface investigation activities are
scheduled, an air rotary casing hammer (ARCH) drill rig may be used. In this case,
continuous coring will not be conducted
A 4-inch diameter Schedule 80 polyvinyl chloride (PVC) well will be installed in the
borehole; the bottom 30 foot well screen will be slotted Schedule 80 PVC pipe, with
0.010-inch slots, and solid Schedule 80 PVC pipe (riser) will be placed from the top of
the well screen to the land surface. The annulus between the groundwater monitoring
well and the borehole will be backfilled with Monterey No. 3 sand from the total
borehole depth to 5 feet above the top of the well screen. A 3-foot thick (minimum)
hydrated bentonite seal will be installed above the sand pack. Hydrated bentonite grout
will be installed from the top of the bentonite seal of the shallow sand zone filter pack to
2 feet below grade. Concrete will be placed from 0 to 2 feet below grade. A traffic -rated
vault will be installed around the groundwater monitoring well and completed at grade. A
locking cap will be placed on top of the PVC riser at grade and a bottom PVC cap will
either be screwed on or secured with stainless steel screws for each groundwater
monitoring well. Construction details will be evaluated during well boring activities and
the final well construction information will be presented in the assessment report.
IdcmolAgrreementAllincon Consultants, Inc. (Landfill Leachate Environmental Site Assessment) FY2526.016.docx-ms
Following installation of the groundwater monitoring well, well development activities
will be conducted. Well development activities will be initiated at least 48 hours'after
groundwater monitoring well installation. The monitoring well will be developed by
pumping, surging, and bailing until sediments in the bottom of the groundwater
monitoring well are removed, the extracted water becomes clear. The groundwater
monitoring well will be developed until water quality parameters (i.e.,pH, temperature,
conductivity, and turbidity) stabilize. The water quality field parameters will be collected
and recorded throughout the development process.
Task 3,2 Laboratory Analytical of Groundwater Installation Soil Sampling
Soil samples will be collected at 100, 150, 200, and 250 feet bgs during the boring
activities associated with the installation of the groundwater monitoring well at MW-01.
Consultant estimates that the soil samples collected (four total soil samples) will be
analyzed for the COCs listed in Task 2.2.
Task 3.3 Well Surveying
The newly installed groundwater monitoring well will be surveyed by a State of
California Licensed Land Surveyor. The elevation and the latitude and longitude of the
top of well casing will be surveyed for the groundwater monitoring well.
Task 3.4 Groundwater Sampling
The newly installed monitoring well will be developed prior to groundwater sampling. A
minimum of 3 days following well development, one groundwater sample will be
collected from the newly installed groundwater monitoring well (i.e, MW-01). In
addition, two of the existing wells will be sampled including one upgradient well (i.e., B-
1C) and one downgradient well (i.e., B-4R).
In addition, one groundwater duplicate sample will be collected from the groundwater
monitoring well MW-01.One equipment blank sample will be collected by pumping
PFAS-free water through the sampling pump prior to collection of the groundwater
samples from MW-01.
Prior to groundwater sampling, a PFAS free dedicated pump will be installed at the
groundwater monitoring well. Groundwater sampling will be conducted using a bladder
pump equipped with high density tubing. New tubing will be used to sample each
groundwater monitoring well. Groundwater samples will be stored in a cooler chilled to 4
degrees Celsius and will be couriered to a state- certified analytical laboratory using
chain -of -custody protocol. Precautions will be taken to follow the California State Water
Quality Control Board (SWRCB) sampling guidelines for PFAS outlined in SWRCB
(2020), as outlined in Appendix D of the revised Work Plan.
Task 3.5 Groundwater Laboratory Analytical
Consultant estimates that the three groundwater samples plus one field duplicate and one
equipment blank sample will be analyzed for COCs including:
• Title 22 Metals by EPA Method 6010Bn47W7471A
• VOCs by EPA Method 8260B

Bemo\AgreementsOncon Consultants, Inc. (LmWill Leschate Fhviromnentat Site Assessment) FY2526-016.docx.ms
• SVOCs by EPA Method 8270C
• Chlorinated pesticides by EPA Method 8081
• Total petroleum hydrocarbons (full carbon chain) by EPA Method 8015B
• Chlorinated herbicides by EPA Method 8151
• Perchlorate by EPA Method 314.0
• PFAS by DoD QSM Version 5.1 or later.
• Specific conductance by SM 251013.
In addition, groundwater samples will be analyzed for general chemistry parameters (i.e.,
total organic halides, total phenolics, fluoride, chloride, nitrogen as nitrate, sulfate,
hardness as calcium carbonate, phosphate, phosphorus, orthophosphates, pH,
temperature, total organic carbon, bicarbonate, carbonate, hydroxide, alkalinity, total
dissolved solids, and chemical oxygen demand) as described in the revised Work Plan.
Task 4 Drilling Services
This task budget was developed to reflect the drilling services and general management
of the drilling subcontractor for the drilling and well development services described in
Task 2 and Task 3.
Task 5 Investigation Derived Waste Management
Upon completion of sampling at each boring location within the sludge drying bed, the
boring will be backfilled with hydrated granular bentonite using a tremie pipe and capped
to match the pre-existing ground surface. Investigation derived waste (IDW) such as soil
cuttings, water removed during well development, and decontamination water will be
stored in US Department of Transportation (USDOT) approved containers (Le., drums or
a roll -off bin), pending laboratory analytical results for offsite disposal at an appropriate
receiving facility. One composite soil sample will be collected from the containers used
to dispose of the soil cuttings from the installation of the groundwater monitoring well.
Similarly, one composite water sample will be collected from the containers used to
dispose of the water removed during well development (three total water samples). One
composite soil sample will be collected from the containers used to dispose of the soil
cuttings from the deep and shallow soil sampling within the sludge drying bed.
All USDOT-approved containers will be stored in a pre -determined location onsite,
pending laboratory analytical results for waste characterization and disposal. The two soil
samples and one water samples collected from the IDW drums will be analyzed for the
full suite of analytes as described in Tasks 2.2 and 3.5.
Task 6 Reporting
Task 6.1 Well Completion Report
Consultant will submit a Well Completion Report to the County within 30 days of well
installation.
Task 6.2 Draft Leachate Investigation Report
Consultant will prepare a report describing the results of the landfill leachate
investigation. The report will present the analytical data and boring logs to characterize
10
1Acmo\Agrecmentslaincon Comultmits, hie. (Landflill Leachate Enviromnental Site Assessment) MS26-016.doex-ms
the likely extent of environmental impacts associated with the leachate disposal, and
provide recommendations for next steps (e.g., options for remediation, or additional
assessment, if warranted).
Task 63 Final Leachate Investigation Report
Rincon will respond to comments received from the SA RWQCB to fmalize the Leachate
Investigation Report,
Task 6.4 Response to Comments and RWQCB Coordination
This task will only be used on an as -needed basis to respond to any comments from the
RWQCB and to coordinate with the RWQCB during any report revisions.
Task 7 Project Management, Meetings, and Administration
Project management and administration task will cover ongoing correspondence with the
City and the SA RWQCB, invoicing, and administrative project management cost,
including coordination with field staff and coordination with subcontractors including the
analytical laboratory, drilling subcontractor, and land surveyor.
Assumptions
Consultant has made the following assumptions in the preparation of this proposal:
Task 1
• Consultant is not responsible for any damages to underground improvements not clearly or
accurately marked by the City. Consultant will contact DigAlert for utility mark -outs; however,
it should be noted that DigAlert often does not mark the location of subsurface utilities located
on private property. If Consultant damages any subsurface utility or structure that is not
identified by the City, then the City will assume the cost and all liability related to repair and
injury that may occur as a result of such an occurrence.
• Consultant understands that the processing of the well permits will require approximately 6-
weeks by the County and that schedules will be developed accordingly.
• The geophysical survey will be completed within I day if required by the City of Redlands.
Task
• Laboratory analytical costs included in this proposal assume a standard turnaround time of 7 to
10 days for all analytes with the exception of PFAS. Turnaround times for PFAS analytical
results are anticipated to be approximately 3 to 6 weeks. Laboratory analysis may be expedited
for an additional fee.
• Consultant assumes that 20 percent of the soil samples will undergo Soluble Threshold Limit
Concentration (STLC) testing for up to two metals (i.e., 14 total STLC tests), and that an
additional 10 percent of the samples will undergo Total Threshold Limit Concentration (TCLP)
testing for up to two metals (i.e., 7 total TCLP tests) to characterize the pond material for
potential disposal purposes.
• Costs include the assumption that each sample will be analyzed for all target analytes; however,
consistent with the Work Pfan, if constituents are not detected in shallow soil samples applicable
screening levels, deeper samples will not be analyzed for that particular analyte.
• Collection of deep and shallow soil samples is expected to take 3 days to complete.
• Task 2 will be completed following the completion of the pre -field activities described in Task
3.
11
I: 1eraMgreementsOmon Consultants, Inc. (Landfill Leachate Environmental Site Assessment) FY2526.016.docx-ms
Task 3
• Consultant assumes that 20 percent of the soil samples will undergo STLC testing for up to two
metals (i.e., 2 total STLC test), and that an additional 10 percent of the samples will undergo
TCLP testing for up to two metals (i.e., 1 total TCLP test) to characterize the pond material for
potential disposal purposes.
• Task 3 includes the phased installation of a total of one groundwater monitoring well.
• Installation of the one groundwater monitoring well and well development is expected to take
up to 6 days to complete.
• Time and effort associated with soil sampling during groundwater well installation is included
in the 6 days to complete the one groundwater monitoring well.
• Laboratory analytical costs included in this proposal assume a standard turnaround time of 7 to
10 days for all analytes with the exception of PFAS. Turnaround times for PFAS analytical
results are anticipated to be approximately 3 to 6 weeks. Laboratory analysis may be expedited
for an additional fee.
-The costs described herein assume groundwater monitoring wells will be installed using a Sonic
drill rig. Use of another type of drill rig may incur additional costs
• It is assumed that groundwater will be encountered at approximately 250 feet bgs. Should
groundwater be encountered at shallower depths, a California Certified Professional Geologist
will make recommendations for well construction given shallower groundwater.
• Groundwater sampling activities are assumed to be completed within t day for the well initially
installed at MW-01, and an additional day to sample the two existing groundwater monitoring
wells and the newly installed groundwater monitoring well, following development.
• Well surveying will be completed within one mobilization.
• A 4-inch diameter Schedule 80 PVC well will be installed in the borehole, and the bottom 30
foot well screen will be slotted Schedule 80 PVC pipe, with 0.010-inch slots. The solid Schedule
80 PVC pipe (riser) will be placed from the top of the well screen to land surface.
• The annulus between the groundwater monitoring well and borehole will be backfilled with
Monterey No.3 sand from the total borehole depth to 5 feet above the top of the well screen.
• A 3-foot thick (minimum) hydrated bentonite seal will be installed above the sand pack.
Hydrated bentonite grout will be installed from the top of the bentonite seal of the shallow sand
zone filter pack to 2 feet below grade.
• Concrete will be placed from 0 to 2 feet below grade. A traffic -rated vault will be installed
around the groundwater monitoring well and completed at grade. A locking cap will be placed on
top of the PVC riser at grade and a bottom PVC cap will either be screwed on or secured with
stainless steel screws for the groundwater monitoring well.
• Consultant's labor costs include oversight and management from a California Certified
Professional Geologist throughout groundwater monitoring well installation.
• The drilling subcontractor will use a City -provided water meter to obtain PFAS-free water to be
used during well development activities.
Tasks
• Costs for 1DW include STLC or TCLP analysis. If metal concentrations do not require
additional analysis to determine whether disposal as hazardous waste is required, these costs will
not be incurred.
• Rincon assumes up to 35 drums of soil material and t7 drums of water to be stored on -site for
up to 90 days during the well installation activities.
12
I1em0AgrwmentslRincon Consultants, Inc. (Landfill Leachate Envimmnental Site Assessment) FY2526-016.doox-ms
• Consultant assumes soil waste generated during soil boring activities within the Discharge Area
will be characterized as hazardous waste due to the potential for PFAS impacts, and therefore
will be disposed of separately as hazardous waste. However, the waste soil will be sampled and
characterization will occur following the review of analytical results. If waste soil is
characterized as non -hazardous, the waste generated during soil boring activities will be disposed
of with the waste generated during groundwater well installation activities.
• Soil and water waste generated during groundwater well installation and development activities
are assumed to be non -hazardous; however, Rincon will collect one waste sample per drum for
waste characterization. If the waste generated during groundwater well installation and
development activities is found to be hazardous, additional disposal fees will be incurred.
Task
Rincon assumes that the effort required to prepare the Leachate Investigation Report will include
one round of revisions following review by the SA RWQCB.
Task 7
• Administration costs were prepared assuming up to 1 hour of invoice preparation per month,
for up to 12 months of project administration.
• An assistant Project Manager will review invoices, prepare invoices for the City, and provide
updates for the City via phone and email on a regular basis.
• Prior to each mobilization, the Rincon Feld program manager will spend up to 3 hours in
