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 o Site Plan General Topographic and Drainage Characteristics General Soil and Hydrogeological Characteristics Location of Proposed Monitoring Wells Construction Details for Monitoring Wells Analytical Parameters to be Tested Sampling Frequency and Quality Assurance Laboratory Requirements for Sample Analysis o o o o o o o The overall hazardous materials response plan is included here by reference and should be reviewed for situations not addressed in this report 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 1 Ja ~t~' .~~;~:~ v.' ~:l~J' 1) ."_ '-r ( j-..'~. i h:;j' '\. \ r" ~ ~~ -r" l)L .:::;i~~ ~I~f":';-~:f~ Ie .

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 3 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 4 ;nU~;"''''~;' :~~ ::>>, .1, .t J ~ I ""- ",,"-- ~.., } t. .'. .. ::1. .I~ i n ." -~ .. . . ~ .! 1 -'. ,-. </ :) ~~-:-::1 LWOO ~ L'" --...--- ") r:-:> r.., ~~i ~3 ~ :J ~ ~ -, -, ~ ..; 2t \ :J ,:a.M.": -, ~ClIq.CIQ .. 1 m'~" . .. -1 - X":"I n., ~ '~"'"'<:> ~ .... \\ ~ nnnr'l i1 1 n~o:"':lo ~ nnn~' n !1 n " \) -" ,",\.- ~ .. , / : 1 1.
