Re: Revised Remediation Estimates Berry Property Dear Mr. Hull: Based on comments during our last meeting, Environmental Consulting & Technology, Inc. (BCT) has revised our cost estimates for the soil excavation alternative. The revisions include: · Expanding the temporary soil vacuum extraction task as recommended by Miles Ballogg; · Add an oxygen. releasing compound to the tank pit excavation as an added assurance that remediation will be successful; and · Collecting an additional set of ground water samples to document water quality prior to the excavation. This second round of ground water samples will be used to justify that a monitoring period is not warranted following the soil excavation. Should the initial set of water quality results show significant petroleum contamination, then we will need to consider other alternatives such as a post excavation monitoring period or additional ground water remediation. The revised cost for the soil excavation alternative is $52,135.17. If you have any questions regarding this information, please contact me. Sincerely, ENVj.QNMENTAL CONSULTING & TECHNOLOGY, INC. <<Ii 111III " Mark A. Culbreth, P.G. Senior Hydrogeologist ~J:lJJ:l' A.

FL 33609 (813) 289.9338 FAX (813) 289-9388 March 17, 1997 Mr. Paul Richard Hull Assistant City Attorney City of Clearwater Post Office Box 4748 Clearwater FL 34618 - 4748 Re: Berry Property Remediation Dear Mr. Hull: Environmental Consulting & Technology, Inc. (BCT) has completed a file review and prepared the pilot study report for the referenced facility. The purpose of this letter is to provide the City with our understanding of the current site. conditions and propose remedial alternatives to rapidly and cost effectively remediate the site. It is likely that the FYREZYME did provide some benefit by accelerating the reduction of dissolved hydrocarbons detected in ground water samples collected during the pilot study. There are two factors currently affecting the dissolved hydrocarbon concentrations: The monitoring wells were reportedly installed to a depth of 10 feet below land surface. However, when ECT collected samples from the wells in February, the wells were only approximately 5.5 feet deep. Although some silting is expected in the bottom of the wells, it is unlikely that 4.5 feet of sand and silt would have accumulated in the bottom of the wells. The effect that this has on the dissolved hydrocarbon concentration is to yield higher concentrations because a smaller portion of the water column is being sampled. The manner in which the FYREZYME was introduced into the subsurface did very little toward remediating the soils at and above the water table. Therefore, the contaminated soils which currently exist are acting as a continuing secondary source of contamination. The Florida Department of Environmental Protection (FDEP) will ultimately provide comments on the pilot study report and then request submittal of a remedial action plan (RAP). Remedial alternatives are very limited due to the existing residential land use. It will not be possible to install pumps, blowers, or other standard remediation equipment. C:\SHARON\CULBRElIDLE1TER\BERRY.DOC An Equal Opportunity/Affirmative Action Employer J I Mr. Paul Richard Hull March 17, 1997 Page 2 The objectives of the proposed remedial actions that will be described in the RAP will be to: Reduce the concentrations of petroleum hydrocarbons in the soils to a point where free product is no longer observed in the monitoring wells and the soils no longer act as a secondary source of-ground water contamination; and -' Reduce the concentrations of petroleum hydrocarbons in the ground water to levels below the site rehabilitation levels. As a point of reference, Figure .1 is provided to illustrate the extent of soil and ground water quality impacts as reported by Meavers & Associates.ECT has developed two remediation strategies which we feel will remediate the residual contaminated soils and ground water. The following is a discussion of these strategies and a description of tasks identified as necessary to complete remediation at this site. SOIL EXCAVATION As a result of the installation of the injector wells and lack of any type of seal around them, the soils underlying the driveway have been washed out leaving voids beneath the concrete around each of the wells. Given this scenario, it is likely that the Berrys will request that their driveway, or portions thereof, be replaced as part of their settlement. Figure 2 shows the distribution of injector wells and the approximate extent of the driveway that would likely be requested to be replaced. Since a significant portion of the driveway will need to be replaced, it would be easy to excavate the contaminated soils. The advantage of this approach is that excavation is the fastest remedial technology available to mitigate contaminated soils. In addition, it is readily acceptable by the regulatory agencies and would provide the property owners with the comfort of knowing that the contamination has been removed from their property. An additional advantage to this approach would be that the time required to obtain closure on the project would be much quicker and post excavation monitoring would not likely be required. The disadvantage to this approach is that the residual soil contamination reportedly present beneath the garage would not be removed. However, the FDEP has approved no further action recommendations where contaminated soils were inaccessible, provided that no sensitive receptors were likely to be impacted. The following is a series of tasks identified to complete remediation under this scenario. C:\SHARON\CULBRETHILE1TERIBERRY.DOC Ee'T En"ironments' Consulting & Technology, Inc. I I Mr. Paul Richard Hull March 17, 1997 Page 3 Temporary Soil Vacuum Extraction The purpose for extracting the soil vapors is to minimize the volume of soils that may ultimately need to be excavated and to also. attempt to reduce the concentrations of hydrocarbons in the soils under the garage that are not accessible. ECT would propose to use a mobile soil vacuum extraction system to pull soil vapors from injection wells 0, G, H, I, and monitoring wells. MW-l, MW-6, and MW-7. The soil vacuum extraction system will be operated continuouSly for six hours twice a week for three weeks. Soil Sampling Soil analytical data will be used to evaluate the lateral extent of soils that need to be excavated. Soil samples will be collected at the 11 locations shown in Figure 3. Since there are no guidelines for using organic vapor. analyzer data to identify excessive contamination in soils containing heating oil, the samples will be analyzed for the volatile organic aromatic aromatics by U.S. Environmental Protection Agency (EPA) Method 8020 and for the polynuclear aromatic hydrocarbons by EP A Method 8100. These data will be compared to the leachability standards. Several proposed leachability standards have been proposed. ECT proposes to use the leachability standard designed to be protective of marine surface waters. Table 1 is a summary of the existing soil cleanup criteria, Those soils that contain hydrocarbons . greater. than. the selected leachability standards will act as a source of ground water contamination. Monitoring Well Installation As previously discussed, the existing monitoring wells only contain a sufficient volume of ground water during high tide. As a result, the ground water samples are not characteristic of the surficial aquifer, resulting in an artificially higher dissolved hydrocarbon concentration. ECT proposes to install properly constructed monitoring wells to document to the FDEP that representative ground water samples do not contain dissolved hydrocarbons above the site rehabilitation levels. ECT would propose to pull and replace monitoring wells MW -1 and MW -7 and then install one additional monitoring well near the center of the garage as shown on Figure 4. These wells will be properly constructed using a hollow stem auger drilling rig. Each well will be installed to a depth of 12 feet below land surface and will contain 10 feet of O.OlO-inch slotted schedule 40 PVC screen. The screen will be connected to two feet of PVC casing by threaded flush joints. A filter pack consisting of a graded 30/40 silica sand will be placed in the borehole around the screen of each well. The filter pack will extend to 6 inches above the top of the screen. A 6-inch thick fme sand seal will be placed above the filter pack and the remainder of the borehole filled with a neat cement grout. Each well will be C:ISHARON\CULBRETH\LE1TERIBERR Y.DOC Eel' Environmenlsl Consulting & Technology, Inc. I I Mr. Paul Richard Hull March 17, 1997 Page 4 completed below grade, inside of an 8-inch diameter steel casing and surrounded by an 18-inch by 18-inch by 3-inch concrete pad. . Following installation, each well will be developed by surging to loosen fine grained materials present in the formation material and in the filter pack, Each well will be pumped to remove the fine grained materials from. the filter pack and well. This process enhances the hydraulic connection between. the well and the surrounding formation, which provides water quality samples and liquid level measurements representative of the aquifer. All cuttings and development water will be containerize<fand properly diSpOsed of. Following installation, the elevation of each well will be surveyed to a common datum. In addition, a temporary measuring point will be marked<m the seawall and its elevation surveye4 to the same common datum as the wells. Ground Water Sampling Following installation of the monitoring wells, ECT propOses to collect ground water samples from the new wells. Each of the samples will be analyzed for the volatile organic aromatics by EP A Method 602 and the polynuclear aromatic hydrocarbons by EPA Method 610. All sampling procedures will follow ECT's FDEP-approved procedures for sampling, preservation, sample handling, and shipping. ECT proposes to contract with Environmental Conservation (ENCO) Laboratories or Savannah Laboratories to provide analytical testing services for this project. ECT will calculate the volume in each well to be sampled, then bail five well volumes prior to sampling, Following sampling, an additional bailer full of water will be collected and the temperature, pH, conductivity, and dissolved oxygen content of the well water will be measured. Prior to sampling, liquid levels will be measured in each well and at the seawall. These depth to liquid measurements will be converted to water level elevations using the survey data. The results of this ground water sampling event should document that the concentrations of dissolved hydrocarbons are below the site rehabilitation levels. Remedial Action Plan Preparation Because of the presence of free product at the site, the FDEP will require remedial actions to abate the source of potential ground water contamination. Should the ground water C:\SHARON\CULBRETIl\LEITERIBERRY.DOC eel Envlronmen'.' Consul/ing & Technology. Inc. I I Mr. Paul Richard Hull March 17, 1997 Page 5 samples indicate that the concentrations of dissolved hydrocarbons are near or below the site rehabilitation levels, ECT would prepare a soils only RAP. Soil Excavationtrreatment ECT would, excavate the area east of the underground storage tanks and south of the garage as delineated by the analyses of the soil samples. The soils would be excavated to one foot below the water table to guarantee removal of the contaminated soils. Figure 5 shows the approxirilate extent of the proposed soil excavation, The soils will be hauled off-site and thermally treated by a licensed contractor. Confirmatory soil samples will be collected from the sides of the excavation to document removal of the contaminated. soils, . The confirmatory soil samples will be analyzed for the volatile organic aromatics by EP A Method 8020 and ~e polynuclear aromatic . hydrocarbons by EPA Method 8100. These analyses will be compared to the soil cleanup goals identified in Table 1. The excavation will be backfilled and properly compacted. The driveway will be replaced by a construction contractor. Confirmatory Ground Water Sampling While the excavation is still open, ECT proposes to install one temporary monitoring well in the approximate location of the existing well MW -7. A ground water sample will be collected from this well and analyzed for the volatile organic aromatics by EP A Method 602 and the polynuclear aromatic hydrocarbons by EP A Method 610. Closure.Report Following the receipt of the analytical results, ECT would prepare a closure report documenting the removal of contaminated soils and the, ground water quality characteristics. This report will contain a no further action recommendation. Well Abandonment Following approval of the no further action recommendation, the FDEP will require that the remaining wells be properly abandoned by a licensed water well contractor. ECT will coordinate with a water well contractor to remove the concrete pad and manhole from around each well and to pull the PVC from the ground. The borehole will be filled with a neat cement grout to land surface. C:\SHARON\CULBREllf\LE1TERIBERRY.DOC Eel' Environmenlal Consulting & T echnotogy, Inc. I I Mr. Paul Richard Hull March 17, 1997 Page 6 IN-SITU BIOREMEDIA TION Should the City of Clearwater or the Berrys no desire to excavate the contaminated soils, ECT could implement a. bioremediation strategy. The advantage to the bioremediation strategy is that the driveway would not need to be dug up. However, the disadvantage is that this remedial strategy will take longer to implement, require four quarters monitoring after the remedial action objectives have been met. The following is a series of tasks identified to complete remediation under this scenario. Even after the site rehabilitation goal~have been reached and the FDEP has approved a no further action recommendation~ the Berry's may still require that their driveway be replaced as part of their settlement. Monitoring Well Installation ECT would propose to pull and replace monitoring wells MW -1 and MW -7 and then install four additional. monitoring wells at the locations shown on Figure 6. These wells will be properly constructed. using a hollow stem auger drilling rig following the same procedures as described above. Ground Water Sampling Following installation .of the monitoring wells, ECT proposes. to collect ground water samples from the new wells. Each of the samples will be analyzed for the volatile organic aromatics by EP A Method 602 and the polynuclear aromatic hydrocarbons by EPA Method 610. All sampling procedures will follow ECT's FDEP-approved procedures for sampling, preservation, sample handling, and shipping. ECT proposes to contract with Environmental Conservation (ENCO) Laboratories or Savannah Laboratories to provide analytical testing services for this project. ECT will calculate the volume in each well to be sampled, then bail five well volumes prior to sampling, Following sampling, an additional bailer full of water will be collected and the temperature, pH, conductivity, and dissolved oxygen content of the well water will be measured. Prior to sampling, liquid levels will be measured in each well and at the seawall. These depth to liquid measurements will be converted to water level elevations using the survey data. Remedial Action Plan Preparation ECT would propose to prepare a RAP that would consist of both soils and ground water treatment as discussed in the tasks outlined below. C:\SHARON\CULBRETIN.ETlCRIBERR Y.DOC Ee'T Environmental Consulting & Technology, Inc. I I Mr. Paul Richard Hull March 17, 1997 Page 7 Ground Water Treatment ECT proposes to use an oxygen releasing compound (ORC) to oxygenate the ground water, thus providing the needed oxygen to support microbial activity and degradation of the petroleum hydrocarbons. The compound will be introduced into the subsurface through the use. of a Geoprobe at approximately fifteen locations (Figure 7). The Geoprobe will pump a slurry into the soils to a depth of ten feet below the water table. FYREZYME will be added to the ORC slurry to provide surfactants and enzymes to stimulate microbial growth. Soil Treatment ECT proposes to inject a FYREZYME slurry into the vadose zone at approximately 27 locations throughout thear:ea. The purpose of the FYREZYME is to breakup the residual petroleum hydrocarbons using the surfactants and induced microbial growth. Approximately one month later, ECT will inject an ORC slurry into the same locations. The ORC will provide an oxygen source to support the microbial growth induced by the FYREZYME. Monitoring ECT will use the existing injector wells to monitor the oxygen and carbon monoxide concentrations every two weeks. An increase in oxygen concentrations will document the release of oxygen by the ORC. An increase in carbon dioxide concentrations will document the degradation of the petroleum hydrocarbons by the microbes. As the oxygen concentration decreases to the baseline concentration another application of ORC will be injected into the subsurface. When the carbon dioxide concentration decreases to the baseline concentration, 6 soil samples will be collected to document the reduction in hydrocarbon concentration. Soil samples will be analyzed for the volatile organic aromatics by EP A Method 8020 and the polynuclear aromatic hydrocarbons by EPA Method 8100. In addition, ground water samples will be collected quarterly to monitor the decrease in dissolved hydrocarbon concentrations, Monitoring Only Plan Once the ground water has reached the site rehabilitation levels, ECT will prepare a monitoring only plan (MOP). It is anticipated that the ground water will reach the site rehabilitation levels within one year and therefore, the MOP will serve as the annual report. The MOP will identify the wells selected for sampling. The ground water C:\SHARON\CULBRETIl\LETrERIBERRY.DOC Eel' Environmentsl Consulting & Technology. Inc. I. I Mr. Paul Richard Hull March 17,1997 Page 8 samples will be analyzed for the volatile organic aromatics by EP A Method 602 and the polynuclear aromatic hydrocarbons by EPA Method 610. Site Closure Report Following the monitoring period, a site closure report will be prepared and will contain a no further action recommendation. Well Abandonment Following approval of the no further action recommendation, the FDEP will require that the remaining wells be properly abandoned by a licensed water well contractor. ECT will coordinate with a water well contractor to remove the concrete pad and manhole from around each well and to pull the PVC from the ground. The borehole will he filled witha neat cement grout to land surface. . COST ESTIMATES The estimated cost for the soil excavation scenario is $42,833.74. The estimate for the in situ bioremediation strategy is $81,303.98. The cost estimate for the bioremediation strategy is based on one year of treatment followed by one year of post-treatment monitoring. Following your review of this report, please contact me to set up a meeting so that we may discuss additional details regarding the remedial alternatives.
