Laboratory Reports I. Introduction Braun Intertec was authorized by Dakota Counry to conduct a subsurface investigation at 1534 Lone Oak Road in Eagan, Minnesota. The azea to be investigated was usaci as a disposal site for rubber col}ected at Fort Snelling during World Waz II. The purpose of this investigauon was to assess subsurface conditions and confirm the absence of potentially hazardous waste. The site is located in a residential azea, and several houses overlie or aze adjacent to the fill azea. A seismic survey conducted previousty indicated that the waste ranges in thiclmess from a few feet to approximately 30 feet and is overlain by 0 to 14 feet of soil. II. Scope of Work The following tasks were performed by Braun Intertec for this project. A Site-Specific Safety Plan was prepazed. A hollow-stem auger boring was conducted through the waste at the location specified as VW-1 on the attached site map. The boring was advanced ihrough the waste until native soils were encountered at approximately 23 feet. Samples of the waste were collectefl from an approximate depth of 10 feet and from 20 feet for analysis of RCRA metals and ubestos. The borehole was monitored for methane, and the cuttings were screened for organic vapors using a photoionization detector (PID). At the termination of the boring, a split-barrel soil sample was collected. The soIl was screened for organic vapors using jaz headspace procedures, and a sample was collected for analysis of volatile organic compounds (VOCs) using MDH Method 466A, polynuclear azomatic hydrocarbons (PAHs) by Method SW-846 8270 and RCRA metals. A vapor monitoring well was installed to a depth of 20 feet in the boring. A consizuction diagram is provided in Appendix A. Approximately 24 hours and 48 hours after instailation, methane concentrations in the vapor well were measured. An air sample was also collected using a chazcoal tube for analysis of VOCs. Dakota County Project No. CMA,Y-45-0722 November 22, 1995 Page 2 • Three additional soIl borings were conducted for installadon of temporary monitoring wells. These temporary wells were labeled PZ-1 through PZ-3. Localions aze shown on the attached site map. Well construction diagrams aze provided in Append'u A. • After purging three well volumes, groundwater samples were collected from each of the temporary wells and analyzed for the following pazameters: Field pH Total RCRA metals VOCs by IvIDH 465E Dissoived RCRA metals PAHs by EPA 610 Total Alkaiinity Ammonia as Nitrogen Sufide Potassium Ca hazdness Nitrate as Niuogen Sulfate Sodium A duplicate sample pabeled PZ-A) from PZ-3 and a field blank were also colleaed and analyzed. Ail analytical samples were placed in a cooler and transported to our laboratory following standazd chain-0f-custody procedures. • The wells were removed and the boreholes were sealed after sampling was compieted. • Waste cuttings were placed in drums and are being stored temporarily az Braun Intertec. Foc disposal purposes, a sample of the waste cuttings was analyzed for RCRA metais using TCLP. As requested by Dakota County, we aze coordinating disposal with USPCI. M. Results A. Site Geology and Hydrogeology As indicated by the boring logs (Appendix A), all borings encountered 3 to 4 feet of topsofl. At VW-1 and PZ-3, the topsoil (not native) was underlain by rubber debris to depths of 23 feet and 21 feet, respectively. Siz to 7 feet of clayey sand was encountered in PZ-2 and PZ-3 at different horizons. The remaining soils consisted of silty sand and poorly graded sand. •t Dakota Counry Project No. CMXX-95-0722 November 22, 1995 Page 3 The water table occurs az a depth of about 25 feet at the locarion of PZ-3. At PZ-1 and PZ-2, which are located at the base of a hill, the water table was about 2.5 feet and 0.2 feet below the surface, respectively. The groundwater flow direction is southwesterly, consisteirt with topography (Figure 2). B. Waste Characteristics The waste rubber observed in the soil borings was shredded and chopped into small to medium pieces. It appeared to consisi primarily of clothing remnants such as boots or raincoats. Chemical analysis of tlte waste for RCRA metals indicated high concentrations of azsenic, bazium, cadmium and lead (Table 1). No asbestos was detected in the samgles. Laboratory reports are contained in Appendix B. TCI.P analysis of RCRA metals was performed on a sample of the waste cuttings. Results are included in Appead'u B. Concentrations are below the limits established for the toxicity characteristic. Therefore, the waste is not considered to be hazardous. C. Analytical Resuits for Soil and Groundwater The soil sample collected from beneath the waste in VW-1 contained relatively low concentrations of azsenic, bazium and chromium (Table 2). No other RCRA metals, VOCs or PAHs were detected. Groundwater analyticai results are summarized in Table 3. Two VOCs, bromodichloromethane and chloroform, were detected in at least one well; however, concentrations were below the Minnesota Department of Health, Health Aisk Limit (HRL). Two PAHs, benzo(k)fluoranthene and benzo(a)pyrene, were detected in PZ-3 at relatively low conceirtrations. No HRL has been established for these compounds, but for comparison, they are below the Maximum Contaminant Levels (MCis) established for public drinking water supplies. The first extraction for the PAH analysis did not work, and therefore, the sample had to be re-ectracted past the EPA recommended holding time. The quality of the resulting data is not believed to have been significandy affectefl. The tota( RCRA metals concentrations for the groundwatec samples are high. This is likely a resuit of sediment in the samples since the dissolved conceatrations are relatively low or were not detected. If the weiis had been rigorously developed and allowed to set longcr, the total metals concentrations would likely have been much lower. Dakota Counry Project No. CrXX-95-0722 November 22, 1995 Page 4 D. Vapor Monitoring Results No VOCs were detected in the air sample collected from the vapor monitoring well (Appendix B). Very lugh methane concentrations (169b gas by volume) were measured in the vapor monitoring well both one and two days after instailation. _ IV. Conclusions and Recommendations Two of the borings at the site encountered waste rubber at 3 ro 4 feet below ground surface. The thickness of the waste at these locations was 18 m 19 feet. Analysis of the waste indicated high concentrations of inetals, particulazly bazium and lead. Results of TCLP analysis indicate that the waste is not hazardous under the toxicity chazacteristic. Based on water levels measured in the temporary monitoring wells, groundwater at the site is flowing southwest, consistent with topography. Concentrations of total metals in the groundwater aze high. However, since dissolved metal concentrations are, for the most part, below detection limits, the total metal concentrations aze likely due to sediment and not a reflection of groundwater quality. A soi] sample collected from unmediately below the waste did not indicate elevated levels of inetals in the soils. The major environmentai concem at this site is the presence of explosive gas (methane) in ihe subsurface. The source and lateral exteat of the methane is unknown. We did not observe any significant organic material in the waste rubber which would be likely to produce high concentrations of inethane. It is unlikely that the cubber itself wouid produce explosive gas. Other potential sources for the methane are: leaking natural gas lines, abandoned septic systems, sewers, or other unknown deposits of degrading waste. The porous nature of the shredded rubber may provide a conduit or a repository for the methane. The aznount of inethane detected in the vapor monitoring well is over three times the lower exptosive timit (200 percent of the lower explosive limit is 5 percent gas by volume). These levels aze considered high and may present a significant risk to the safety of nearby residences if gas enters the dwelling or other confined spaces at explosive concentrations. As we discussed with Dakota Counry personnel during monitoring of the vapor well on October 13, 2995, the basemenu of the three houses closesi to VW-1 should be monitored for methane and methane alarms should be installed. In addition, vapor monitoring points should be installed next to the foundaUOns of the houses. . ?€ Dakom counry Projea No. OIIGY-95-0722 November ZZ, 1995 Page 5 We recommend that the potendal sources of tiLe metfiane be imesagated. At a m;n?TMnm. dtis could include: . discussions with the locai ;as compaay, including potenriai sampiing and "fingerPrinting" of dte gas; • monitoring of nearby. sewess for expiosive aas; and . interviews with adjacent home owners ro obtain informacion oa rhe location of old sepdc systems, composs piles or other nearby disposal sices. Based on the informarion obtained, addiuonal smdies shouid be perfoffied ro determine the extent of the methane and to evaluate potendal coaecrive measures. V.

March 15, 1996 Mr. Dale Wegleitner City of Eagan 3830 Pilot Knob Road Eagan, MN 55122 RE: Braun Intertec Study of the Lone Oak Road Disposal Site Dear Mr. Wegleitner: I BARRY C. SCHADE DIRECTOR (612) 891-7011 FAX(612)691-7031 APPLE VALLEY MINNESOTA 55124-8579 This letter is intended to bring you up to date on the investigation of the Lone Oak Road disposal site since my January 2 letter to you. As I mentioned in that letter, a study done by Braun Intertec Corporation indicated two immediate concerns: the high methane concentration in the vapor monitoring well and the high level of lead in the waste material itself. Methane production is due to a natural decomposition process carried out by bacteria when there is a lack of oxygen. This process requires a source of organic material that is easy to decompose. Since rubber waste does not easily decompose, it is not likely to be the source of the organic material that is producing methane. Regardless of the source, the presence of inethane gas is considered to be the most immediate concern. With an adequate supply of oxygen and an ignition source, methane gas at the level detected during the Braun sampling could result in an explosion if the methane gas were concentrated in an enclosed area. Therefore, our first concern is possible migration of the methane gas into homes and buildings where oxygen coupled with an ignition source could be present. We have taken the following steps to determine what is occurring in this area and ensure the safety of the residents: . We have checked for the presence of inethane gas in the basement of each home in the area at least once and, at the owners request, checked three homes a second time. No methane was detected on these occasions. . We had NSP do a fingerprint test on the methane gas detected in the vapor monitoring well, and NSP indicated that it was not natural gas from a leak in the gas distribution line. Pnnted on recycleC paper, 20%post-consumer `? AN EOUAL OPPOflTUNITV EMPLOYEH .. • We had probes installed at depths of about four feet and six feet next to the basement at 1534 Lone Oak Road, to test for methane near the house. We found no methane gas at these locations. We have contracted with Braun Intertec to continue the study of the site. In late February Braun personnel, accompanied by Environmental Management staff, installed additional probes in various locations on the disposal site to check for the presence and movement of inethane. The final results from these probes are not yet available, but we will contact you when we have them. However, we are continuing to find high levels of inethane gas in the area where the fill is deepest. As I indicated in my January 2 letter, we are also planning to sample surface soils from area yards and gardens in the spring. We will analyze those samples for the same metals, including lead, that were detected previously in the waste. I am enclosing a copy of the Braun Intertec Corporation report of its Fall 1995 study of the site and a summary of the report, prepared by Environmental Management staff. Since notices of claim have been filed with Dakota County regarding some of the properties in this area, please contact Jay Stassen of the Dakota County Attorney's Office at 438-4564, if you have questions on this site or the County's activities. Sincerely, Barry C. 5efiade, Director Environmental Management Enclosures o1swr/site/rebmrp3 N BRAUNINTERTEC REPORT RUBBER DISPOSAL SITE ON LONE OAK ROAD In October 1995, Dakota County contracted with Braun Intertec, an environmental consulting firm, to study the rubber disposal site on Lone Oak Road in the City of Eagan. The main objective of the Braun study was to evaluate the chemical characteristics of the waste, the ground water in the area and the gas in the waste. Terms Used in the Report: RCRA metals refer to eight specific heavy metals that are commonly found in industrial products and are tested for routinely to determine whether a waste has hazardous characteristics. TCIP analvsis refers to a laboratory method of dilution and extraction used to determine if particular chemicals are present and if they will move through the soil or waste. VOCs, Volatile Orqanic Compounds, are a class of compounds that are normally associated with industrial solvents and may be found in soil or ground water where improper handling or disposal has occurred. PAHs Polv Aromatic Hvdrocarbons, are a class of organic compounds that are normally formed during high temperature burning or heating of other organic compaunds. HRL, Health Risk_Limit, is a concentration limit set by the Minnesota Department of Health for a particular chemical that has been determined to be dangerous to heafth if ingested for a certain period of time. MCL Maximum Contaminant Level, is the federal standard set for the allowable contaminant level for public drinking water supplies. Total value refers to the entire amount of the chemical present in a sample, including sediment, compared to chemicals in solution that have been filtered or filtered and diluted, such as TCLP samples. Watertable is the upper layer of the first saturated (water bearing) sand or soil that is encountered when drilling. Dissolved Metals are metals in a water solution that cannot be removed by filtering. Often metals in solution are part of a compound or are attached to ? particles of silt or clay and will be removed when the water is filtered either naturally through sand, or with a commercial or laboratory filter. MDL, Minimum Detection Level, is the lowest concentration at which a chemical may be detected for the analytical procedure used. Chemicals may be present at a concentration that is less than the MDL. Jar Headsoace Procedure is a quick method used in the field for determining if VOCs are present in soil or waste as drilling is being done. PVC, Polv Vinvl Chloride, is a hard plastic commonly used in manufacturing pipe to be used for plumbing. VW-1 is the vapor well installed by Braun Intertec where samples of the waste were obtained and where a plastic perforated pipe was installed to sample methane and other gases that might have been present. PZ-1. PZ-2 and PZ-3 are the three temporary groundwater monitoring wells installed by Braun Intertec. PZ-3 was instalied on top of the hill and PZ-1 and PZ-2 were installed on the lower level of the property. Summary of Sampling and Analytical Results: Braun Intertec did borings to obtain ground water samples at three different locations on ihe site. They also used borings to obtain waste rubber samples at two depths, soii samples below the waste, and samples of the gas in the waste. Ground Water The water samples were taken with a fen foot pertorated PVC pipe section that was installed a few feet below the watertabie. The water samples contained various amounts of sand, silt and clay sediment. The ground water was found to be high in total metals before filtering but after filtering, most of the metals were below the MDL. The VOCs and PAHs found in the water were determined to be at levels below concern for health standards for drinking water. Rubber Waste and Soil The waste that was obtained through the boring was a mixture of soil and rubber pieces. Two samples were taken from the waste rubber for analysis: one at 10 feet and one at 20 feet. One sample was also taken of the soil below the waste, at about 25 feet. The samples of waste rubber tested high in a number of metals, especially lead, but the soil below the waste tested very low in metals. Vapor Monitoring A perforated PVC pipe installed into the waste to collect gas samples. The samples were analyzed for gases that were present, and methane was the major gas that was detected. The concentration of inethane was found to be about 16%. Braun Conclusions and Recommendations . Analysis of the waste indicated high concentrations of inetals, particularly barium and lead. . The high concentrations of total metals in the ground water are likeiy due to sediments and are not a reflection of groundwater quality. . The major environmental concern at this site is the presence of inethane in the subsurface. The levels of inethane are high and may present a significant risk to the safety of nearby residences ifi gas enters the dwelling or other confined spaces at explosive concentrations. The basements of the three residences closest to VW-1 should be monitored for methane and methane alarms should be installed. Also, vapor monitoring points should be installed next to the foundations of the houses. The potential sources of inethane should be investigated and additional studies should be performed to determine the extent of inethane and to evaluate potential corrective measures.
