Subject Quan-tul'l Park Groundl.later Monitoring Plan
After reviewing the above-referenced docul'lent we offer the following
recol'll'lendations
The wells I'Ientioned in the proposed plan would effectively sal'lple
only one zone in the aqUifer; i e 5 feet above NGVD to 10 feet
belol.l NGVD Provisions should be I'Iade to sal'lple various depths
Z On page 3 the subl'littal I'Ientions that rainfall on the site
percolates into the ground or drains west-southwest to the C-16
or E-4 canals Yet the author assul'les groundwater flow to be east
or southeast Although the overall groundwater gradient along the
lower east coast I'Iay be in an east-southeast direction, it I'Iay be
unreasonable to aS5Ul'le that the upper level of the aqUifer flol.ls
opposite to the topographic gradient
3 If the intent of the I'Ionitoring plan is to provide an early
detection and warning systel'l for groundwater contal'lination then
the wells should be located as close as possible to the potential
spillage site We should therefore have the option of Plodifying
the location and nUl'lber of wells based upon the individual site
plan subl'littals
4 SOl'le of the proposed wells should be installed as soon as feasible
60 as to allow the accul'lulation of baseline data

RE QUANTUM PARK GROUNDWATER MONITERING PLAN
Please be advised that I have reviewed the draft of the
above-referenced document The report indicates that groundwater
flow beneath the site is assumed to be east or southeast Based
on this information, the following additional measures are
recommended:
1 Construction of an additional monitering well near the
northeast corner of the southerly industrial tract, adjacent
to the Seaboard Railroad right-of-way (north of well no 6
and east of the cul-de-sac road);
2 Construction of additional monitoring wells on the
east side of 1-95; and
3 Well samplings undertaken every three (3) months as opposed
to every six (6) months.
It is not known if the above measures are practical or feasible
It is believed, however, that implementation of the above would
result in greater protection of the surficial aquifer and may
also afford greater public safety

Introduction
Quantum Park is a proposed commercial, industrial, and office
park in Boynton Beach, Florida, which is to be developed in
accordance with a Development Order (DO) approved by the Treasure
Coast Regional Planning Council and the City of Boynton Beach.
The DO stipulates that Quantum Park prepare an early warning
monitoring plan for hazardous materials to be approved by the
South Florida Water Management District (SFWMD). As part of the
hazardous materials response plan, a plan which identifies the
groundwater monitoring strategy at the site is to be developed
On June 4, 1987, representatives of Quantum Park contracted
Resource Engineering and Planning, Inc (REP/Inc.) to prepare the
groundwater monitoring plan in accordance with SFWMD guidelines
The purpose of this plan is to present recommendations and
guidelines for groundwater monitoring which are developed from
site-specific information This will include a description of

Site Description
Quantum Park straddles Northwest 22nd Avenue between Congress
Avenue and Interstate 95 in western Boynton Beach, Florida The
park is bounded on the south by canal C-16 of the Lake Worth
Drainage District (LWDD) and to the north by High Ridge Country
Club. In all, the site occupies 560 acres in Sections 16, 17,
and 20, Township 45 South, Range 43 East Figure 1 presents the
location of the site from the Lake Worth Quadrangle of the United
States Geological Survey (USGS) 7~ minute topographic map series
Of the site area, approximately 153 acres are zoned for
industrial development, 146 acres for office space, 30 acres for
commercial development, 123 acres for preserve, open space, lakes
and wetlands, 46 acres for research and development industrial,
and 17 acres for a city park. At present, the site remains
largely undeveloped, with the exception of road work and initial
construction on an industrial parcel in the southern portion

General Topographic and Drainage Characteristics
With the exception of the eastern portion of the site, Quantum
Park occupies a nearly level low-lying area west of the Atlantic
coastal ridge. Surface elevations of the central and western
portion of the site are between 7 and 20 feet above National
Geodetic Vertical Datum (NGVD). The coastal ridge occupies the
eastern third of the site, where the surface elevation is between
20 and 43 feet above NGVD
The general drainage of the site is poor. Precipitation which
falls on the site percolates into the ground or drains west -
southwest off of the coastal ridge to LWDD Lateral Canal C-16 to
the south, or LWDD Equalizing Canal C-4 to the west
General Soil and Hydrogeological Characteristics
Soils of the coastal ridge within the park consist of the Paola
and St. Lucie sand complexes, which are characteristically well
drained soils with slopes of 0-8%. Other areas 20 feet above
NGVD in the park consist of these two soil types or the Pomello
fine sand complex, which occurs on low ridges or knolls with
slopes of 0-5% The low-lying areas of the park consist of the
Basinger and Myakkan depressional soils, or the Basinger fine
sand complex These two soil types characteristically are poorly
drained fine grained sands which occupied grassy sloughs in the
eastern portion of Palm Beach County prior to development The
isolated depressions within the park consist of the Okeelanta or
Sanibel mucks, which are characteristically very poorly drained
organic soils, and are commonly under water for at least a
portion of the year
The Quantum Park site is underlain by 320-340 feet of generally
unconsolidated sand, shell, and clay of the Anastasia and Fort
Thompson Formations of the Pleistocene. These formations
comprise the sediments of the surficial aquifer of eastern Palm
Beach County and are underlain by indurated calcareous clays of
the Pliocene
Groundwater flow direction beneath the site is assumed to be east
or southeast The proposed monitoring wells will be used to
develop water table contour maps for the wet and dry seasons
The average transmissivity of the surficial aquifer sediments is
100,000 - 300,000 gallonsldaYlfoot, with an approximate rate of
flow of 25-30 feet per year, excluding outside influences. Water
quality beneath the site is unknown, but is thought to be good,
despite a high iron and hydrogen sulfide content, and may be
potable with a minimum of treatment
The sources for the above soil and hydrogeological
characteristics are the Soil Survey of Palm Beach County, USGS
Water Resources Investigations Report No 67, USGS Water-
Resources Investigations Report No 86-4067, and the Report of
the Wellfield Protection Ordinance Subcommittee published by Palm
Beach County

Location of Proposed Monitoring Wells
It is proposed that nine (9) monitoring wells be constructed in
the areas of greatest industrial activity to provide an effective
means for early detection of any groundwater degradation in these
areas. The industrial and researchldevelopment parcels are
concentrated in the southern and northeastern portions of Quantum
Park, and it is proposed that the monitoring wells 'be constructed
in these areas to evaluate any impact from industrial activity.
Figure 2 presents a site plan of Quantum Park with the nine
proposed monitoring well locations and the numbering scheme used
in this plan. These well locations are essentially the same as
those proposed by the SFWMD, and are felt to be adequately
arranged to provide reasonably early detection of groundwater
degradation in the industrial areas of the park.
All attempts will be made to install the nine monitoring wells
out of the way of proposed development and construction Should
it become necessary to abandon a well due to impending
development of the particular parcel, an alternate monitoring
well will be similar to those of the original well The
abandonment of the original well and the installation of an
alternate well will take place only after the approval of the
SFWMD.
Monitoring Well Construction Details
The ground surface elevation at the nine proposed monitoring well
locations varies from approximately 10 feet above NGVD to 25-35
feet above NGVD. Given this condition, the terminal depth below
land surface for the wells will vary to facilitate a screened
interval in all wells of approximately 5 feet above NGVD to 10
feet below NGVD.
All nine wells will be constructed in similar fasion Bore holes
will be drilled using hollow stem augers. Well casings and
screens will be constructed of 2-inch diameter flush-thredded
schedule 40 polyvinylchloride (PVC) pipe. Each bore hole will
penetrate to a terminal elevation of approximately 10 feet below
NGVD. Well screens will consist of a fifteen-foot section of
slotted (0 02 inch slot) 2-inch diameter PVC pipe The well
casing will be inserted through the auger stem into the borehole
and, as the augers are raised, the annular space between the
borehole and casing packed with washed medium-coarse grained (6-
20 grade) sand Sand pack will continue above the top of the
screen for a minimum of one foot and a maximum of two feet The
sand pack will be topped with a two-foot thick bentonite seal,
and the remaining space filled with a bentonite-cement grout.
Any exposed portion of the casing above ground surface will be
covered with a 4-inch diameter steel guard pipe with hinged
locking cap If any wells are completed below grade, a steel
meter box will house the well head, which will be fitted with a
cap and a locking strap Figure 3 presents a typical monitoring

Sampling Frequency and Quality Assurance
The nine monitoring wells at Quantum Park will be sampled
following initial development and tested for the parameters
listed above to establish baseline conditions at the site prior
to construction Following this initial sampling, the wells will
be sampled once every six months with the results of each
sampling forwarded to SFWMD by Quantum Park upon completion.
These semi-annual sampling events will be scheduled to correspond
with the wet seasonldry season cycle of South Florida These
seasons are roughly defined as June-October (wet season) and
November-May (dry season).
