Hameed U Malik, Ph.D., P.E.May 21,2000 Environmental Engineer Department of Pubic Works & Engineering 530 Greene Street, Room 701 Augusta, GA 30911 Attention: Dr. Hameed U Malik Subject: Proposal for Statistical Data Evaluation of Groundwater Quality and Preparation of a Monitoring Program for Groundwater at the Deans Bridge Road Landfill in AU2usta-Richmond County, Geor2ia Dear Dr. Malik: Stephen E. Joseph & SAGES, Inc. present this proposal to provide environmental services and consultation for statistical data evaluation and preparation of groundwater monitoring . program at the above listed site. This letter presents the proposed course of action to develop this work. PROJECT CONSIDERA TIONS Our understanding is that the Deans Bridge Road Landfill has groundwat,er data from previous sampling events in Dumpstat@, which will be made available for use in the statistical data evaluation for this site. Augusta-Richmond ,County will supply a current site map and any site background information that is available. The site map should show the monitoring well locations. It is our understanding that additional groundwater samplings have been completed by others in 1999 and 2000. The groundwater potentiometric map should show the groundwater flow direction and the groundwater gradient for the water bearing zones. It is our understanding that there are 28 groundwater monitoring wells in Landfill Sections II-A and Il-B as well as 25 groundwater monitoring wells in Landfill Section II-C. It is also our understanding Augusta-Richmond County would like to pursue the possibility of .' improving their groundwater monitoring program by selecting better indicator parameters and reducing the number of constituents and monitoring wells. It is our understanding that the County is using the "Dumpstat@" computer program for groundwater monitoring and as a database and groundwater analysis program. Augusta-Richmond County also desires to evaluate the impacts of landfill gas on groundwater quality. In reviewing some of the available groundwater data, it appears that the site is impacted by the migration oflandfill gas. We have worked on groundwater monitoring programs for landfills in Georgia, Hawaii, California, Oregon, " ~.. . ~;- ~. \ 7 j;x ~~ ,'~"," and Arizona and at these landfills we have found that control of landfill gas can greatly reduce or migrate VOC impacts to groundwater. Our geologists are licensed in the States of Georgia, 'Oregon, California, and Hawaii. As a member of the Hawaii Landfill Task Force, ourselves along with representatives from Waste . Management, Inc., USA Waste, Inc., and other landfill operators have worked closely with the Department of Health, State of Hawaii in developing a Landfill Guidance Document that outlines the procedures and type of landfill monitoring parameters to be used in groundwater monitoring. Members from this group are on or have worked closely with the ASTM committee that developed ASTM method PS 64-96. This group is also currently working on the portion of the guidance document for the assessment and corrective action. Parts of this guidance are being used by other states in their groundwater monitoring programs and has been presented to the GA- EPD already. The procedures and parameters outlined in this document are higWy recommended for incorporation into your groundwater monitoring program as they provide an accurate and cost effective method of meeting EPA Subtitle D and GA-EPDrequireinents. TheGA-EPD has also reviewed the "Dumpstat@" program and is favorably impressed with the program. We will assist the County in attempting to have the State of Georgia accept the idea of reducing and changing the number and type of constituents in the groundwater quality program by' providing supporting evidence for this position. Our success will depend on the amount and quality of the data available, number and locations of monitoring wells, and the regional and site geology. We propose to prepare an evaluation of the impacts to groundwater quality from landfill gas VOCs. We will show trends in the impacts to groundwater by VOCs and help Augusta- Richmond County in designing and locating gas extraction wells to further reduce the impacts of landfill gas to groundwate~ quality. SCOPE OF WORK SEJ will provide the following services: Task 1 This task is to provide consultation and help to the County to evaluate the impacts of landfill gas to groundwater quality and changes in trends of landfill gas impacts to groundwater quality. We will help the-County in the design and location of additional landfill gas extraction wells to further reduce landfill gas impacts. Task 2 Prepare a Groundwater Quality Evaluation of the existing data for the Deans Bridge Road Landfill in that Augusta-Richmond County, Georgia using a standard monitoring plan. As part of this evaluation we will assess whether the site needs to be in assessment monitoring or if other options are more appropriate. This evaluation will include the following components based on available information: ,., '. . ,t' '" ~ ,,", " 'ro;o, . Characterization of monitoring well concentrations including the means and standard deviations; · A comparison of the groundwater monitoring results with water quality maximum contamination levels (MCL); · A comparison of groundwater monitoring results to the existing tolerance intervals; · A statistical comparison of intrawell samplings along with a statistical evaluation and development of tolerance intervals at the 95 % confidence level. . Recommendations will be made based on the evaluation of the groundwater data. · Two meetings with the Georgia EPD will be included to present the evaluation and recommendations. Task 3 A groundwater monitoring program will be developed including the following components: · Site description and geologic setting; . Hydrogeologic Setting; · Groundwater flow direction and velocity; · Documentation of the monitoring well network and the visual inspection program; · Sampling procedures; · Laboratory procedures; · Summary of background analytical monitoring data; · Evaluation of monitoring data and a suggested detection monitoring program and · Conclusions and recommendations. Development of an adequate groundwater monitoring program is critical for early detection of possible releases from the landfill and to reduce long-term monitoring costs. Monitoring for just priority pollutant metals and volatile organic compounds, such as has been done in past at Deans Bridge Landfill, will not allow for early detection ofleakage from a landfill facility. Other compounds are historically better at detecting release from landfills. In addition, these other compounds are more definitive in comparing different waters that may be beneath the landfill and how they are interacting. These other compounds can also reduce the long-term laboratory cost of monitoring. Task 4 An optional task is to provide consultation and help to the County to setup its own monitoring plan. It appears that the County has personnel with sufficient expertise and experience to do their own groundwater sampling and the initial statistical evaluation of the results. This would further reduce the costs to the County for the ongoing groundwater monitoring program. The only outside consultation needed would be tne development of the groundwater quality monitoring program and independent review of the statistical evaluation and conclusions for each of the groundwater quality reports. '1 . . - .. r :- I.. I, . " J t '"'". '. FEE AND SCHEDULE Our services would be provided on a time and expense basis at $80 per hour, For your budgeting purposes, the lump sum costs will be $4,500 for Task I, Costs for Task 2, evaluation of the groundwater data and meetings with the EPD, will be $7,860. The lump sum costs for Task 3, developing a groundwater monitoring program, are approximately $6,000. Costs for Task 4, additional consultation, review of reports and meetings, as necessary, will be provided on a time and expense basis. The lump sum costs for Task 4 will be $3,000. It is estimated that work will take place over the next six months. /I -;. .. . ;.1. -~ -' '. f-' c-..~ . '.
