The studies involved soil boring analyses, development of additfonal groundwater monitoring wells, sampling and analysis of groundwater, and evaluation of remedial action alternatives. The results of the remedial investigation demonstrate that low levels of contamination, primarily chromium (<35 ppm) , copper (<40 ppm) , and trichloroethene (<100 ug/L) are present in groundwater beneath the site. These were observed at significant levels in only one on-site well and one off-site well , however, the off-site well is not within the groundwater flow path of the site. The contaminants do not appear to be moving off-site or downward within the aquifer due probably to chemical-physical interactions with the silty-clay soil . Soil borings analyses demonstrate that some of the soil • beneath the site is contami- nated with metals (primarily chromium, copper, and nickel ) and that most of the contaminated soil is probably the result of spillage and/or dumpage of liquids in the basement and pole barn area. The evaluation of potential remedial action alterna- tives resulted in examination of five options : ( 1 ) no action, � (2) monitoring groundWater, (3) pump and treat groundwater, (�) cap the� site, and (5) excavate contaminated soils. While site conditions appear to �ustify little or no additfonal actions _ - - given the facts that ( 1 ) contamination appears not to be moving � from the site, (2) little or no potential for human or environ- mentsl exposure exists at the site and (3) little or no impact would result if groundwater left the site (given land use in downgradient direction) . The recommended alternative involves a - , �I��/�o5'�'' . '� complete cap over the site and additional groundwater monitoring as further insura ce that contaminant migration does not occur. The gro ndwater data were limited to two sampling episodes (for all wells) and we feQl that it is prudent to continue monitori g these wells for a period of three years to insure there are o changes in the observed conditions. The addition of a cap to the site Would provide insurance against the � unlikely situatio of deterior�-�ion of aquifer quality from . leaching of conta inants frorr ;::e soil into the sh�llow aquifer. We suggest that this option i: worth the added cost over �ust a monitoring progr . . . . Part I REMEDIAL INVESTIGATION OF THE ECOLOTECH SITE, ST. PAUL, MINNESOTA 9 a-ll�S� . , SUMt4ARY A D CONCLUSIONS OF REMEDIAL INVESTIGATION The Re edial Investigation ( RI) at the E�olotech Site indicates there re several areas of soil contamin�tion. Soils in the basement f the main facility appear to contain elevated levels (compared to background levels) of chromium, hexavalent chromium, copper and possibly lead to a depth of at least 10 feet. Alleged p evious disposal of liquids into the sewer lines from the process'ng area is the most probable source of the metals in the ba ement soils. Soils eneath the pole barn also demonstrated contami- nation with the ame constituents to a depth of approximately 10 feet. The sourc of inetals beneath the pole barn could be the result of leakag or spillage of stored materials in this loca- tion before the uilding was constructed , or leaka�ge through cracks, holes, e c . , in the floor slab after the b'�uilding was constructed. , Soil c ntamination Was detected between 10' and 25' in Well W-1D (court ard well) and is probably the result of lateral migration from p st disposal in the main facility basement discussed above all Well locations are shown in Figure I-2) . The relative lac of surficial contamination at W-1 indicates the source is probab y located below the ground surface, and not from surficial dumpin . � Ground ater contamination is evident primarily in Well W-1 . Although a slight degree of contamination ddwngradient at Well W2-D was no ed in the August 19 sampling ever�t, off-site migration of con aminants does not appear to be significantly altering downgra fent groundwater quality. ' I Well W-6, an off-site well which is not directly downgradient of the site, demonstrated elevated levels of chro- mium and trichloroethene. It is highly unlikely that these • contaminants migrated from the site through groundwater movement. They are more likely either the result of past leakage from the city sewer line (which has been replaced) or from another unidentified source in the area. • In evaluating any potential impacts to human health and the environment resulting from contaminated soil and/or ground- water at the Ecolotech Site, several facts that were observed as a result of the remedial study should be considered. These are : • Only chromium was observed in groundwater at levels exceeding primary drinking water standards. These were exceeded only ,in Wells W1 (courtyard well ) and W-6 (off-site well not directly downgradient) . Copper exceeded secondary drinking water standards in well W1 . • Volatile organics were observed in several wells. These were chloroform (which does not appear to be connected with this site) , and trichloroethene (two wells, W1 and W6) . • While strong downward gradients exist at well nests W1/W1D and W3/W3D, the lack of significant contami- nant migration in the W1/W1D nest indicates that the contaminants are not significantly mobile. This is potentially due to chemical-physical interactions in the silty clays that characterize the subsurface . geology of the site. • While sampling results do not indicate significant , downgradient contaminant flow,. land use in the down- gradient directfon (Calvery Cemetery ) would serve to limit any impacts •should any contaminants migrate from the site in this manner. • To the best of our knowledge, no homeowne'rs or other ' facilities in the area are using the affected aquifer for drinking water or any other purposes. 2 . , � 90��'� Conclusions that can be drawn from the results and observations are: • The potential for human exposure to contaminated soil and/or groundwater is very low. • Con amination of the groundwater is minimal and this imp ct is limited to a small area directly beneath the site. Contaminants do not appear to be moving dow gradient. • The contaminants in the soil and in the groundwater app ar to be immobilized or limited in mcvement by int ractions with clay or other soil particles pro iding some natural protection of the aquifer. 3 , ., � 1 .0 SrLTRODUCTION AND BACKGROUND The St. Paul Ecolotech facility is located at the corner of Jameson Street and Front Street in St. Paul , Minnesota (Figure I-1 ) . The facility was last used for a circuit board recovery operation and consists of one building used for office, storage and processing of materials, and a pole barn used to store accumulated materials for later processing. Circuit board scraps and 55-gallon drums of copper-bearing etching and plating solutions were accumulated on-site for the purpose of processing them to recover metals. Much of the material accumulated was not processed and was stored on-site for several years. The process- ing that occurred on-site resulted in the generation of wet sludges. - Inspection of the Ecolotech facility by Minnesota Pollution Control Agency (MPCA) personnel and other government officials prior to June 1983 revealed spillage and leakage from damaged containers stored on-site. Alleged violations of state and federal hazardous Waste laws resulted in a court order for the removal of waste materials and cleanup of the site. Drums were staged and removed from the site by 0. H. Materials (OHM) . Cleanup began in 198� and was comp3.eted in January 1986. OHM completed a limited investigation of near surface and subsurface conditions at the site in January of 1986 . This investigation included inspection of sewer lines, soil samgling, and installation and sampling of three groundwater monitoring wells. Analyses performed during this investigation indicated limited presence of inetals (primarily chromium, copper and T - nickel ) in soils and groundwater at the site. A summary of their - findings is presented in Section 3•0 of this report. I-1 � . �j j�-1!o c!

The study w�s conducted by Radian/Warzyn Engineering during the summer of 1986. This section documents the activities, data collected and findings of the RI performed at the Ecolotech Site. The objectives of the RI were to: • Assess the general extent of site contamination; • Determine the extent of off-site migration of contaminants ; and • Provide sufficient inf ormation to allow development, evaluation and selection of remedial alternatives during the feasibility study, should remedial actions be necessary. - I-3 , - gD�/��'� 2 . � 2. 1 The Eco otech Site is located in Section 26, of T29N, R23W in St. Paul , Minnesota (see Figure I-1 ) . The area is primarily residen ial although there are some comme'rcial estab- lishments in the icinity. The Calvary Cemetery is located across Front Stre t from Ecolotech. 2.2 The sur icial geology in the vicinity of the site i� characterized by lacial �till and outwash deposits that were ' deposited by the es Moines lobe during the Wisconsin stage of glaciation. The ill deposits are of variable composition ranging from clay loams to sandy loams with interbedded sand lenses. The outw sh deposits consist of sand, silty sand and gravel , often ove lain by deposits of silt and clay loam. The thickness of the lacial overburden in the area is �,approximately 80 to 100 feet. The bed ock sequence beneath the glacial �deposits in , the area consist f the Jordan Sandstone (late Cambrian age) which is overlain by the Prairie du Chien Group (do;lomite, some sandstone and sha e) , the St. Peter Sandstone, the Platteville and Glenwood Form tions (dolomite limestone and shale) and the Decorah Shale. A unconformfty exists between the early Ordo- vician Prairie du Chien Group and the St. Peter Sandstone. � I-4 2.3 Be�ional Hvdro�eolo�,y and Groundwater Use The glacial outwash deposits and the Jordan Sandstone, � Prairie du Chien Group and the St. Peter Sandstone yfeld suffi- cient quantities of water to be considered an aquifer. The Platteville and Glenwood Formations and the Decorah Shale act as confining layers separating the aquifer in the glacial deposits • from the bedrock aquifer. The water table in the vicinity of the site ranges from 25 to 40 feet below ground surface. The water consumed by residences and businesses in the vicinity of the Ecolotech Site comes from the St. Paul city water supply. To our knowledge, there are no active water supply wells in the vicinity of the Ecolotech site. I-5 `Z��CO " 8 3 . 0 OHM con ucted the initial investigation of the Ecolo- tech facility. T e investigation included : • Insp etion of sewer lines from the fa�ility to the city sewer system, including sampling and analysis of m terials blocking the lines. • Coll ction and analysis of shallow soil samples (0.0 to 2.0 feet in depth) . • Inst llation of three groundwater monitorirg wells, wate level monitoring and groundwater sampling and anal sis. ' 3 . 1 The sew r line inspection was performed to determine the integrity of he lines and assess the possibility of residual contarr�ination in he lines. Two sew r lines Were identified in the basement of the processing buildi g. One line appears to have been a drain pipe from the first fl or processing area. This line ends at an uncapped pipe in he west wall of the basement. The second line runs from the nor hern end of the basement to the south where it connects to the c ty sewer system beneath Front Street. Block- ages were reveale in both sewer lines and samples were collected by OHM from the 1 nes and a basement floor drain. Analysi of these samples indicates signi�ficant concen- trations of chrom um, hexavalent chromium, copper and nickel.

The RI was designed to provide sufficient information to define the extent of the contamination at and around the Ecolotech facility. The investigation, which was conducted during the summer of 1986 , included soil borings and sample analysis, monitoring well installation, groundwater sampling and geophysical logging of borings. The work plan for the RI was submitted to MPCA prior to the initiation of field activities. As modified from negotiations, the MPCA concurred with the resultant work plan. The locations for the soil borings and monitoring wells are shown in Figure I-2. ' 4 . 1 Soils Investi�ation - The ma�or objective of the soils investigation was to define the extent, if any, of soil contamination. Eight soil borings were drilled during the investigation at locations agreed to by MPCA (all boring locations are shown on Figure I-2) . Borings B-1 through B-5 were drilled with hollow-stem or flight augers. Split-spoon samples were collected for analysis and to provide inf ormation on stratigraphy. Borings B-6 through B-8 were drilled with a hand auger to a depth of 10 f eet in the basement of the main facility. Boring logs for the soil boring� are presented in Appendix B. Selected soil. samples were submit- ted to the laboratory for analysis of arsenic, cadmium, chromium, hexavalent chromium, copper, lead, mercury, selenium, nickel and pH. All metal analyses Were for total metals. Soil samples . collected during drilling of Well W-1D and W-3D, were also submitted for the same analysis. I-10 � �a -��g�' Table I 4 summarizes the analytical results for samples from these boring , with the raw data contained in ;Appendix C. The analytical re ults from the soils investigation indicate the presence of chrom um, hexavalent chromium, copper aind lead above expected backgrou d concentrations for soils in samples collected from Borings B-1 nd B-2 in the pole barn, Boring B!-4 and Well W-1D in the court ard and Borings B-6, B-7 and B-8 in the base- ment of the main acility. In gene al , the upper soil samples at W-1'D in the courtyard are wit in background concentration ranges. Concen- trations increase at 11 . 5 ' (Sample W1D-6) indicating surficial spillage or leaka e are not the cause of the elevated metals at depth. The likel cause is horizontal migration from dumpage of liquids in the ba ement of the main facility (for �xample, along the sewer line) . • • 4.2 The hyd ogeologic investigation conducted during the RI was designed to o tain the required information and included installation of s x additional monitoring wells (see Figure I-2 for locations) , g ophysical logging of the four deep wells, water level monitoring nd groundwater sampling and analysis, as agreed to by the MPCA. ' 4 .2. 1 - ' Six mon toring wells were installed at the site to complement the th -ee existing wells. The rationale for the six wells is discusse below. � • Wells W-1D and W-2D were installed adjacent to exi ting wells� W-1 and W-2, respectively, to deter- min the vertical extent of impacts p�eviously noted I-12 Table Z-4 SiJl�tARY OF ANALYTICAL RESULTS SOIL SAMPLES Sample Depth Hexavalent Nimmber Pt.

Well W-6 was installed on the south side of Front Street south- east of the facility. The intent of these wells was to provide water quality data dowr.gradient of the facility. 4 .2.2 �ubsurface Geolo¢v The borings for the wells were advanced using 4 1/4- inch hollow-stem augers with split spoon samples collected to provide information on soil stratigraphy . Cross-sections A-A' and B-Bt are shown on Figures I-3 and I-4 , respectively. The figures show that stratigraphy beneath the site, itself, gener- ally consists of 10 to 20 feet of silt and silty clay with occasional sand lenses overlying a sand or sand and gravel layer 50 to 60 feet thick. Boring logs from the wells across Front Street (W-2D , W-5D and W-6) show fine coarse sand with some clayey sand layers from the surface to a depth of ?0 feet. Monitoring wells installed in the borings were con- structed of 2-inch inside-diameter stainless steel screen and flush joint padded rise pipe. All well pipe and screen. w2s steam� cleaned before installation. Well construction details are shown in Appendix B. -- Downhole natural gamma logging was performed at moni- - toring wells W-1D, W-2D, W-3D and W-5D to further define subsur- face soil conditions.

Groundw ter was sampled on three occasions (June 27 , August 19 , and Se tember 12, 1986) during the RI and samples were submitted to the aboratory for analysis of arsenic , cadmium, chromium, hexaval nt chromium, copper, mercury, nickel , lead , selenium and vola ile organic compounds (VOCs) . The June 27 sampling was to c nfirm previous results before the installation of the additional wells. VOCs were also sampled for the first time on June 27. The results of the analyses for each event are summarized in Tab es I-6, I-7 , and I-8, respectively . The detailed results re presented in Appendix D. Results from the June 27 sampling confirmed elevated chromium, hexaval nt chromium, copper, arsenic and nickel at W-1 . Though low levels of chromium were detected at W-2,! hexavalent chromium was belo the detection limit of 0.005 mg/L. The pH at W-1 was significa tly lower (�4. 85) than at the oth�r wells. Several VOCs were detected at W-1 . These include raethylene chloride (61 ug/L , 1 , 1 , 1-trichloroethane (6 .2 ug/L' ) and trichlo- roethene (56 ug/L . Chloroform was detected at 5.8 ug/L at W-2 . The res lts from August 19 indicate the sample col- lected from Well -1 contains cadmium (0.010 mg/L) , hexavslent chromium (28.2 mg L) and copper (40. 1 mg/L) at concentrations . higher than the s te background levels established � at Well W-?. - The pH of this sa ple (3.51) is also low.

In addition, trans- � • 1 ,2-dichloroethan , Which was observed at 18 ug/L, is probably � there as a degrad tion product of TCE. , Low lev ls of chloroform (2.2 to 5.2 ug/L) were detected at Wells W-1D , W-2, W-3D , W-5 and W-5D. These wells generally do not how any impact f rom the facility with respect to the other para eters monitored . Therefore, the levels of chloroform noted are probably background levels, ut�related tc Ecolotech. The September 9 results generally confirm the August 19 results, with the exception of Well W-2D. 'The second sampling at W-2D shows a sig ificant reduction with respect to chromium, hexavalent chromium, copper, nickel and cadmium. Whereas W-2D indicated chromi m above the primary drinking water standard of - 0.05 mg/L, on Au ust 19, the later results indicat+e chromium st detection limit f 0.001 mg/L. Contrary to the reduction in . . I-24 . � r chromium concentrations at W-2D on September 9 , chromium values increased at W-6 . The same volatile organic compounds identified during the August 19 samplfng were confirmed during the September 9 sampling. The levels of trichloroethene and 1 , 1 , 1-trichloro- ethane at W-1D were very similar during both sampling events. The concentrations of trichloroethene and trans-1 ,2-dichloro- ethane increased at W-6 from 39 mg/L to 99 .mg/L (trichloroethene) and 12 ug/L to 41 mg/L (trans-1 ,2-dichloroethane) . Low concen- trations of chloroform were again detected at Wells W-1D, W-2, W-3D , W-5 and W-5D. . I-25 . ��1�� , . REFERENCES 1 . Bloomgren, B.

PAUL, MINNESGTA . � �o-rl�� SUMMARY AND ECOMMENDATIONS OF THE FEASIBILITY' STUDY From an nitial list of nine remedial alte,rnatives, five were selected as being technically feasible and potentially having some positi e environmental and/or public health aspects. These five are sum arized in Table II-1 along with cost estimates for capital cost a d present worth. Given th low levels of contamination observed in the remedial investiga ion, the fact that contamination does not appear to be movin off-site and the low probability of� any adverse public hea th or environmental effects, litt�le additional reRediation appear to be justified at this site. The sugg sted r-emedial alternative, capping the site to prevent rainfall/r noff from infiltrating through the site effectively elimin tes further contaminant leaching 'from the soil and further reduce the potential for contaminants in the ground- water to move off- ite. A continued groundwater monitoring program is recomme ded to demonstrate that contaminants are not moving off-site an to detect any changes in status ,quo. The reco mended capping option involves concrete paving � of the courtyard a d adjacent area, the installation of roof drains on the buil ings , and construction of gutters to divert surface runoff awa -from the site. . This cap ing scenario is recommended above the multi- - layer designs whic were also considered because it is expected to provide the sam level of environmental protecticn at a significantly lowe cost. Also, because of the current ownership 1 t • . ' . status of the property, it is not certain that demolition of the buildings would be the responsibility of the Generators Group. The pumping and treatment of groundwater by ion exchange prior to discharge to the sanitary seaer system does not appear to be �ustified given the costs involved, the low concen- tration of contaminants that would potentially be removed and the small quantity of total contaminants in the ground�ater. Excavation is an extreme and expensive measure which would not result in additional environmental benefit over capping the site. In addition, excavation and removal of soil would require extensive controls to avoid impacting public health by exposure to dust and dirt. 2 . - ��1��g . . � � , .o This rep rt presents the results of a feasibility study of remedial action alternatives for the Ecolotech Si;te in St. � Paul , Minnesota. This study was performed as part of an agree- ment between the colotech Generators Group and the Minnesota Pollution Control Agency (MPCA) . The tec nical objective of evaluating remedial actions at the Ecolotech ite is to examine the potential environmental benefits of furth r reduction of migration of contaminants, . primarily copper nd chromium, which are present to a limited extent in the gro ndwater and soil at the site.

' Each of these .rem�dial action alternatives is descri�ed briefly in the fo lowing paragraphs. ' _ II-1 i `. �, 1 .0 SNTRODUCTION This report presents the results of a feasibility study of remedial action alternatives for the Ecolotech Site in St. � Paul , Minnesota. This study was performed as part of an agree- ment between the Ecolotech Generators Group and the Minnesota Pollution Control Agency (MPCA) . The technical objective of evaluating remedial actions at the Ecolotech Site is to examine the potential environmental benefits of further reduction of migration of contaminants, . primarily copper and chromium, which are present to a limited extent in the groundwater and soil at the site. Nine remediation alternatives were identified which are applicable to the Ecolotech Site. The cost and technical feasibility of these alternatives were evaluated. Environmental, public health and community response considerations were also addressed . The identified alternatives are listed below: 1 ) No action ; ' 2) Continue monitoring ; 3) Pump groundwater and discharge to sanitary sewer; 4) Pump groundwater, pretreat for metals and discharge to sanitary sewer ; 5) In-situ treatment of groundwater ; 6) In�situ treatment of soil ; 7) Cag the site (three types of cap) ; 8) Install a slurry wall; and _ 9) Excavate contaminated soil . Each of these remedial action alternatives is described brfefly in the following paragraphs. � II-1 . � �-1�� , � , . , This alt rnative involve s the implementation of no remedial action at the site. Both groundwater and soils would be left as is. 1 .2 Addition 1 monitoring of groundwater at and around the site would be perf rmed to document the extent to which contarr.i- nant migration fro the site, if any , is occurring. Samples would be collected from the nine existing wells at and around the ' site. The samples would be analyzed for pH, conductivity , arsenic , cadmium, otal cRromium, hexavalent chromium, copper, nickel , and lead. Sampling and analysis would be performed every three months for t e first year and every six month� for the following two year . It is expected that three years of monitor- ing will be sufficient to demonstrate that the situ�tion at th.e Ecolotech Site is stable and does not represent a threat to public health or t e environmen�. If a problem is observed, this option would provi ed for detection of the problem in a timefrarre enabling response. 1 . 3 This alternative would involve the installation of an extraction well o �ite, near the present location of Wl. This well would be 4 i ches in diameter and exterid to a depth of 60 feet, with a scre ned interval from 40 to 60 feet. Groundwater would be removed rom the well with a submersible purr.p and dis- ' charged directly o the sanitary sewer system with no treatment. � II-2 r �� 1 .4 Pump Groundwater, Pretreat for Metals and Discharge to Sanitarv Sewer This option involves the installation of an extraction Well on the site near W�1 and a treatment system to reduce the concentrations of inetals in the pumped groundwater prior to being discharged to the sanitary sewer system. Pumping and treatment would continue until analyses of samples of the pumped ground- water demonstrate that the concentrations of inetals in the groundwater are below specified target levels. These target levels would be agreed upon by MPCA and the Generators Group. The volatile organic concentrations observed do not present an _ operating problem to the municipal treatment plant. Two treatment technologies were considered: physical- chemical treatment and ion exchange. Physical-chemical treatment would involve reduction of hexavalent chromium with ferrous sulfate at low pH, followed by the formation of insoluble metal hydroxides at high pH. The precipitated metal hydroxides would be separated from the aqueous phase by sedimentation. A full time operator would be required and a sludge would be generated which would require disposal . Ion exchange has greater simplicity of operation compared to physical-chemical treatment. A part-time operator would only be required to change the resin in the exchange columns periodically. Two exchange columns in series would be - required : A cation exchange column, followed by an anion exchange column. In the first column, copper, trivalent chromium and other multivalent metal cations uould be removed by a cation _ exchange resin. In the second column, hexavalent chr_omium would • be removed by an anion exchange resin. Fiitration would be required as an initial step to prevent fouling of the columns. II-3 . , � qo�l�� :, , � 1 . 5 - This al ernative would involve in-situ treatment of the groundwater benea h the site to immobilize the dissolved metal contarr:inants pres nt. Effective treatment would ne�essarily involve two steps: reduction of hexavalent �chromium, followed by the formation of nsoluble metal hydroxides. Chromium reduction is accomplished by the injection of a low pH solutipn of ferrous sulfate into the roundwater. The ferrous . sulfate acts as a reducing agent th reby converting the hexavalent chromium to the trivalent state. The second stage of treatment would involve the injection of a high pH alkaline solution into the groundwater to convert the metal cations to insoluble hydroxides. , It is very �ifficult to demonstrate complete treatment for this method. 1 .6 - ' - Soil flushing is the only technically fea�ible soil treatment technolo y identified for the Ecolotech Site. Soil flushing would inv lve the injection of fresh water into the soil at the site and si ultaneously pumping contaminated groundwater out of the soil . n principle, metal contaminants� would be eluted from the so '1 into the water and subsequently removed. . Injection and pump' ng would continue until elution of inetals from the soil no longer occurred . Treatment of the contaminated water which is removed f om the ground would be required prior to reinjection or dis harge. It is difficult to demonatrate that homogeneous treatm nt would result from such treatment. 1 .7 . Three di ferent capping alternatives were 'considered. The first alternat ve involves paving the areas of the site which II-4 t �� are currently unpaved , installing roof drainage systems on the buildings, and providing for surface water diversion off of the site. The areas which are currently unpaved are the courtyard � area and the area between the main facility and the pole barn. The large tank and other debris which are presently in the courtyard area would be removed. Rain gutters and downspouts Would be installed on all of the buildings on the site. A � concrete gutter would be installed between the main facility and the bar and extend along the length of the drive in order to ensure effective surface drainage. Another concrete gutter would be installed along the front of the pole barn to provide drainage for the courtyard and adjacent area. � � � SP� �s G The second capping alternative which was considered �involves demolishing the existing buildings on the site and installing a multi-layer cap over the entire site area. The design of this cap would be consistent with RCRA guidelines for capping hazardous waste disposal sites. The cap would be of a multi-layer design and would consist of three feet of topsoil overlaying a one foot sand layer overlaying three feet of ccm- pacted clay. A vegetative cover would be put in place to prevent erosion of the cap. A third cap design was also considered which would be identical to the second, with the addition of a 30-mill HDPE liner. . � . $ � Tnatallation of a Slurrv Wall This alternative would involve the excavation of a trench around the perimeter of' the site which would be filled with a low permeability material to inhibit the flow of ground- water away from the site. The low permeability fill material would be a mixture of soil and a bentonite and water slurry . The II-5 . � �o�/�► 5� . , . buildings which ar on the site would have to be demalished prior to the installation of the slurry wall . 1 .9 This alt rnative involves physically removing contami- nated soil from th site and transporting it to a landfill which will accept it. T e data from the analysis of sofl borings indicate that soil contamination is present in the courtyard area and the area benea h the pole barn, main facility and storage area. This repres nts approximately two thirds of the site area . and excludes only he drive area and bar. Contamination extends to a depth of 15 t 20 feet. However, near surface soil is not contaminated in some areas where there is evidence of ccntamina- tion at 15 to 20 f et. Two scenarios were considered: excava- tion of the affect d area (approximately 8,700 square feet) to a depth of 15 feet a d to a depth of 20 feet. This removes consid- erable noncontamin ted soil in order to get at the � contaminated - soil. , It is po sible that the excavated material would have to be hauled to a azardous waste landfill for disposal. In order to make this determination, soil samples from the site would have to be t sted with an extraction procedure: If such testing demonstrat s that the metals will not leach from the soil, the excavated material could be haule� to a sat�itary landfill. If the oil fails the EP toxicity �test, the excavated material could be classified as a hazardous waste. $ased on a discussion With a epresentative of the Minnesota Waste Manage- ment Board, it was determined that the nearest hazardous waste � . landfill facilities which would potentially accept the excavated �. material are locat d in Illinois. ' II-6 . , ' � 2.0 SGREENING OF REMEDIAL ACTION ALTERNATIVES An initia2 screening of each of the identified remedia- tion alternatives was performed. The purpose of this screening was to determine whether any of the identified alternatives Were technically infeasible to implement, inconsistent with state and local restrictions, or would result in adverse environmental impacts at and around the site. Based on these criteria, four of the identified remediation alternatives were eliminated. These four alternatives are: • pump groundwater to sanitary sewer (no treatment) , • in-situ treatment of groundwater, • in-situ treatment of soils, and • installation of a slurry wall . The reasons for eliminating these four alternatives from further discussion are presented in the following para- graphs. 2 . 1 Pumo GroLndwater to Sanitarv Sewer (No TreatmPnt) This option Was eliminated after a discussion with a representative of the Metropolitan Waste Control Commission. The local limitations on chromium and copper concentrations in discharges to the sanitary sewer system are 8 parts per million chromium and 6 parts per million copper. The groundwater samples � from W1 show chromium as high as 47 ppm and copper as high as 55 ppm. Treatment aould therefore be necessary prior to discharge to the sanitary sewer. II-7 ��Jf� �� ' •' i � 2.2 - This alt rnative was rejected based on environmental considerations. The contaminants of concern are cop�er and � chromium. Because most of the chromium is in the he�kavalent state, it will not precipitate as an insoluble hydroxide in an alkaline environme t. The hexavalent chromium would first need to be reduced to t e trivalent state. This is accomplished using ferrous sulfate as a reducing agent at low pH. In-situ chromium reduction would involve the in�ection of a low pH solution of � ferrous sulfate in o the groundwater. The presence of this acidic solution co ld result in additional leaching df inetals from the soil into the groundwater. The potential for the migration of dissolved metals would therefore be enh�nced. If groundwater treatm nt were deemed� necessary , above ground treat- ment would be a more environmentally desirable -appro�ch. 2.3 - This alt rnative was eliminated based on botr environ- mental and technic 1 considerations. Flushing appeared to be the only technically f asible technique for treating the soil at the Ecolotech Site. B cause of the small size of the site, any in�ection of additional water into the soil could cause migration of contaminated gr undwater off-site, thereby potentially increasing the ext nt of the plume of contaminated groundwater. Also, soil flushin is in a developmental stage as a technology and has not been s ccessfully demonstrated in the field. The effectiveness of i plementing this technology at the Ecolotech �Site is uncertain nd negative environmental impacts could ' , result. _ . � II-8 . 2.� Tnstall ation of a Sl �rrv Wall This alternative was rejected based on site-specific factors which make the installation of an effective slurry wall technically inf easible. In order for a slurry wall to be effec- tive in preventing the migration of groundwater it must extend to the bedrock beneath the aquifer. If the slurry wall does not extend to an impermeable layer beneath .the aquifer, it will be possible for groundwater to flow under the slurry wall, thereby limiting its effectiveness. The depth to the bedrock at the Ecolotech Site is not known. It is known, however, that it is deeper than 75 feet below the surface of the site. General � geologic information on the site area indicate that the bedrock may be deeper than 100 feet below the surface. • It would not be technically possible to excavate_ a trench to this depth on the Ecolotech Site due to the small area of the site and the sandy nature of the soil beneath the site. II-9 - - �v�1�5� , . � 3 .0 After the initial screening and elimination of remedia- tion alternatives, detailed evaluation of the remaining five remediation alterna ives was performed. These altermatives are listed belox: ' 1 ) No action; 2) Continue monitoring ground�rater; 3) Pump groundwater, pretreat for metsls and discharge . to sanitary sewer; 4) Capping the site; or 5) Excavation •of contaminated soil . _ The above listed alternatives are� discussed in detail in terms of costs and technical and environmental considerations, in the following sections. Documentation and details of al� ccst estimates are pres nted in Appendix E. ! 3 . 1 The impl mentation of no remedial action will result in no change in the e isting situation at the Ecolotech Site. As previously discuss d , it is not expected that any 'significant impacts will occur as a result of the existing situation at the site. _ 3.2 . , The pote tial benefit of this alternative �would be the detection of any c anges in the existing situation at the II-10 , , Ecolotech Site. Potential negative changes which. would be detected include additional leaching of inetals from the soil to the groundwater and migration of contaminated groundwater away � from the site. Continued monitoring would also detect improve- ments in groundwater quality which could occur through natural processes such as adsorption onto soil particles and naturally occurring chemical reactions in the soil . Costs The cost of a continued monitoring program would be associated with collecting groundwater samples from the �existing wells and having the samples analyzed . Analyses would be per- formed for. the following parameters: PH � Conductivity � Arsenic Cadmium Chromium (Total ) Chromium (Hexavalent) Copper Nickel Lead The cost of these . analyses would be $97.00 per sample. Ten samples would be collected during each sampling episode: one - from each of the nine existing Wells and one quality control sample. In addition to the analytical costs, one person day per sampling episode would be required for the sampling. The cost of this option would be 31 , 330 .00 per sampling episode. It is assumed that sampling and analysis would be �performed every three months for the first year and once every' six months for two additional years. The total present worth cost associated with , this option is $9,935. . . II-11 - �v�l��'� ..� � � 3 .3 " The pote tial environmental be�nefit associated with this alternative i the removal of a portion of the contamination which is cur�ently present in the groundwater. The risk of pollutant migratio away from the site would therefore be further reduced . There is however, no indication that contamination is leaving the site, ecause we believe that W-6 ��contaminants" are not the resvlt of roundwater movement from the site. �' The tota amount of pollutants estinated to be present in the groundwater is 46 kilograms of copper and 37 kilograms of total chromium. T e assumptions and documentation of this estimate are prese ted in Appendix F'. It is anticipated that only half of this otal quantity could be rPmoved by pumping due to dilution caused by the flow cf uncontaminated groundwater tcward the extract on well after pumping is initiated . For technical and cost reasons, only ion exchange was considered as a treatment option. Costs � ' � The capi al cost associate with this option is esti- mated to be $52 ,20 . The major items which contr�bute to this ccst include: an xtraction well , a submersible pump, a car- tridge filtration ystem, a cation exchange column, and an anion exchange column. he operating costs associated with this _ alternative are es imated to be $3 , 33o per month during the period when ground ater is being pumped and treated.� Tr�is co�t includes weekly mo itoring, , electricity for pumping, replacement II-12 � ; � � of filter cartridges, and regeneration of ion exchange resin twice per month. In order to estimate the present worth cost associated with this alternative, it uas assumed that pumping and treatment of groundwater Would occur for two years. During this period , sampling and analysis of the groundwater Which is pumped would be performed Weekly to determine the quality of the water priar to treatrr�ent. Pumping and treatment Would cease wr,en such samplin� and analysis de�onstrate trat the levels of ccntarinants in the pumped groundwater do not exceed specified levels, which would be � agreed upon by MPCA and the Generators Group. � Also during this period , sampling of tr,e existing wells would be performed as described .under the discussion of the continued �nonitoring alternatfve. The total present worth cost associated with this alternative is estimated to be $138 ,400. 3 .4 Ca�jn� the Site Teehnicai and Environmental Gonsiderations Capping of the site Would prevent rainwater frorr percolating into the soil which could solutilize netals an� add tc the contamination of the groundwater. Capping is an estab- lished remediation and aaste disposal technology with denor.- strated effectiveness. Cost . � Costs were developed for each of the three capping � alternatives which Were considered. Tre capital cast associated . with the first capping opticn is estinated to be v12,800.

This - i� r,ot �!-,e si�aati n for t::is s:�e. � - II-14 � .. . � , Several other factors should also be ccrsidered . These factors include the noise and general disruption of th� site during the excavation. These condi,tions wculd in all prabability evoke a negative response from the comr�unity. Another factor is the possibility for windborn transport of contaminated material � during the excavation of the site and the possibility o: relesses �� during the transport of the excavated material . Costs The capital cost associated with excavating the affected area to a depth of 15 feet is estimated to be �1 ,053 ,600. The capital cost for excavation tc 2G feet is estimated to be $1 ,392 ,400. These estinates include costs for demolition of buildings, excavation, backfilling, and hauling of the contarr,inated soil to Chemical Waste Managerrent' s hazardous _ waste landfill in Calumet City, Illinois. It was assumed for costing purposes that disposal of the excavated soil as a hazsrdous waste would be required . The disposal of this soil was discussed with a representative of the Minnesota Waste Management Board wY:o indicated tr.at there are currently no landfills in - biinnesota accepting hazardous waste from comnercial or industrial sovrces. He also concurred that the Chicago , Illinois area was probably as close to St. Paul as any available disposal site. Cost estimates were obtained frorr representst�ves of Chemical Waste Management for transporting the excavate� soil and accepting it at the Calumet City landfill. � Transportation costs are based on a quote of �1 ,650.OQ per load at 20 yd3 per 2cad. Disposal costs are based on a quote of $?5.00 per yd3 glus $6.00 - per yd3 Illinois tax. The operatin� costs assoc�ated wi�th this . alxernative would be limited to three years cf ronitaring. The _ Fresent worth of excavation. is estimated to be $1 ,063,6G0 :or II-15 . r • �/`r �'D �. .. .. excavation to a de th of 15 feet and $1 ,402, 300 for excavation to a depth of 20 feet. 3.6 After an evaluation of the five options baSed on technical and cost considerations, we recommend capping the site and continued moni oring of groundwater for a period of three years. The recomm nded capping option involves concrete paving of the courtyard a d ad�acent area along with installation of roof drains on the buildings and construction of gutters to divert surface run ff away from the site. A groundwater monitor- . ing program will e able verification that contaminants are not moving offsite or ownward within the aquifer while Qroviding an opportunity to respond to any unforeseen changes in existing conditions.
