Geosyntec Consultants (Geosyntec) is pleased to submit this fee proposal to Indian River County
(IRC) for professional services associated with the completion of a site assessment addendum at
the referenced Former Cattle Dip site. The site assessment addendum activities are based on the
Florida Department of Environmental Protection's (FDEP) review of the Supplemental Interim
Source Removal Report, which recommended supplemental groundwater assessment activities to
delineate the extent of the arsenic groundwater impacts with the submittal of a Site Assessment
Report Addendum (SARA). The arsenic groundwater impacts must be delineated to the FDEP
Groundwater Cleanup Target Level of 10 micrograms per liter (gg/L). The proposed scope of
work for the services anticipated to delineate and monitor the arsenic groundwater impacts has
been broken down into six separate tasks as described below.

Task 1— Preliminary Activities
Geospte&
consultants
Task 1 includes project management for the entire project, as well as all preliminary activities
associated with securing project costs from subcontractors and updating the Site -Specific Health
and Safety Plan to cover the additional assessment activities. Specific activities include:
• Updating the existing OSHA -required, Site -Specific Health and Safety Plan;
• scheduling a utility locate, acquiring field equipment (pumps, water quality meters,
calibration solutions, sampling containers, etc.), subcontracting; and
• project planning and management responsibilities, invoice review, project coordination,
and project administration.
Task 2 — Monitoring Well Installation Activities
Task 2 consists of mobilizing to the site, installing and sampling monitoring wells, and collecting
a soil core for lithologic characterization. Geosyntec proposes to install six monitoring wells
using direct push technology (DPT) drilling techniques at the locations presented on Figure 1.
The monitoring wells will be constructed of 1 -inch PVC and will be installed to a maximum
depth of 15 feet below land surface (ft BLS) with 10 -ft of 0.010 -inch slotted screen with a 20/30
pre -packed sand filter. The monitoring wells will be completed with a 24 -inch by 24 -inch
concrete pad with an 8 -inch manhole. For the monitoring wells located in the wooded area, the
wells will be completed with the 24 -inch by 24 -inch concrete pad with a 4 -inch PVC casing that
is approximately 3 -feet tall (instead of the 8 -inch manhole). Once installed, the monitoring wells
will be developed until visibly free of particulate matter.
Following installation, the newly installed monitoring wells and existing site monitoring wells
will be purged and sampled according to FDEP Standard Operating Procedures (SOPS). The
collected samples and one quality assurance sample (duplicate) will laboratory analyzed for
arsenic by EPA Method 6010. In addition, water levels will be collected from the newly
installed monitoring wells and the existing site monitoring wells to document the groundwater
elevations and flow direction at the site.
Surveying (location, top -of -casing and ground elevations) by a licensed professional land
surveyor of the newly -installed monitoring wells and the current site monitoring wells will be
also completed.

The current cost breakdown of the monitoring well installation assumes only six monitoring
wells will be required to document delineation of the arsenic groundwater impacts. An
additional 100% contingency has been added to Task 2 to cover any additional monitoring well
installations required to achieve arsenic groundwater delineation. Geosyntec will notify IRC and
secure approval for any activities that may require access to contingency fees. Geosyntec's
proposal assumes one day of oversight for the monitoring well installations, one and a half days
of oversight for the monitoring well sampling, and a half a day for completing the "windshield
survey" for the water supply well survey described below. A breakdown of estimated project
costs is included as Attachment B.
Task 3 — Water Supply Well Survey
Geosyntec will perform a "water supply well survey" in an attempt to identify and obtain
information on area water supply wells, as required under Chapter 62-780.600(3)(h) F.A.C. This
survey will focus on locating public water supply wells located within 0.5 -miles of the facility
boundary and private water supply wells (including irrigation wells) located within 0.25 -miles of
the facility boundary. The goal of the survey is to ascertain whether or not the site is located
within proximity to supply wells in the area which could be affected by the arsenic impacts
and/or could affect area groundwater flow. The following subtasks will be performed:
• coordinating with IRC to request and obtain information on County water supply wells
located in the area;
• contacting the St. Johns River Water Management District, the local health department,
and IRC utilities, to request information on permitted supply wells located in the area;
• performing a "windshield survey" from public roads to look for evidence of private
water supply wells (to be completed during the monitoring well sampling event
described above) within 0.25 -miles of the facility boundary; and
• determining whether the Site is located within an established regulated wellhead
protection zone of a public water supply well or well field.
Additionally, Geosyntec will attempt to identify adjacent surface water bodies which could be
potentially affected by or influence onsite contamination.

Task 4 — Site Assessment Addendum Report
Geosyntec will prepare a brief SARA after the installation and sampling of the monitoring wells.
It is anticipated that the SARA will include the following:
• brief description of field activities;
• results of the well survey;
• general lithologic characterization;
• summary tables of the groundwater sampling results and groundwater elevations;
• maps that show the locations of the monitoring well network, provide a summary of the
groundwater sampling results and provide a summary of the groundwater elevations; and
• recommendations.
A draft copy of the report will be provided to IRC for review. Any comments from IRC will be
incorporated into the SARA and a final version of the report will be prepared. One hard copy
and one electronic copy of the final report will be submitted to the FDEP for review and two
hard copies of the fmal report will be submitted to IRC. The final reports will be signed/sealed
by the Florida Licensed Professional Engineer in responsible charge of the project.
A breakdown of estimated project costs is included as Attachment B.
Task 5 — Semi -Annual Monitoring Well Sampling
Task 5 is included to cover one semi-annual sampling event for the monitoring well network,
which will likely be required by the FDEP, assuming a Natural Attenuation Monitoring program
is approved for the site by the FDEP. This event would occur after completion and submittal of
the SARA to the FDEP and approximately six months after the monitoring well network was
sampled previously
existing wells and
This event includes the sampling of the monitoring well network (three
six newly installed wells). It also includes collecting a set of water level
measurements from the monitoring well network. The monitoring wells will be sampled and
purged according to the FDEP SOPS and the groundwater samples collected will be laboratory
analyzed for arsenic by EPA Method 6010.
Task 6 — Semi -Annual Sampling Letter Report
Geosyntec will prepare a Semi -Annual Sampling Letter Report after completion of the semi-
annual monitoring well sampling event. It is anticipated that the Letter Report will include:
