 360 Linden Street‐‐LESAII                         1  1.0 INTRODUCTION    A limited Phase II Environmental Site Assessment (LESAII) was performed at 360 Linden Street property  located in Fort Collins, Colorado (Site).  The LESAII was performed to investigate selected areas that were  identified in a Phase I Environmental Site Assessment (ESAI) performed by Ecological Resource  Consultants, Inc (ERC) dated June 12, 2014.  Specific Recognized Environmental Conditions (RECs) were  not identified at the Site as a result of the ESAI, however several items were identified at the Site that  were inferred to present elevated potential risk for contamination.  ERC recommended that these items  should be further investigated.    Areas from the ESAI targeted for additional investigation as part of this LESAII included the following:       Areas of surface soil staining where equipment has been parked or where drums or containers  may have leaked.     Fly ash that was identified in soil borings installed as part of geotechnical investigations at the  Site.     Groundwater in recently installed piezometers.     The floor drain identified in the building identified as Garage #1 in the ESAI.    2.0 INITIAL WORK PERFORMED    ERC personnel conducted an initial site visit on June 24, 2014.  Upon arrival, the Site was investigated to  identify features described in the ESAI and to match these up to current conditions.  Most of the Site was  in the same condition as noted in the ESAI.  Figure 1 provides a general Site layout, with piezometer and  sample locations.  The two piezometers were locked in protective steel casings and could not be accessed.   ERC requested keys for the locks, and they were delivered to the Site by a technician from Earth  Engineering Consultants (EEC).      2.1 Soil Investigation  Geotechnical soil borings installed by EEC identified cinders and coal ash (fly ash) at depths ranging from  1 to 5 feet below land surface (bls).  ERC used a hand auger to advance borings at several locations to  investigate the fly ash distribution.  Fly ash appears to have been used to level the Site, as it sits on top of  native soils (sandy and silty clay) at various depths.  The fly ash is covered by a thin layer (6 to 12 inches)  of gravel and cobbles (road base) to finalize the grade at the Site.  The fly ash is black, grainy, and is easily  identifiable, with sharp contacts where it sits on top of the brown silty‐sandy‐clayey native soil.      A relatively large surface stain was identified in the ESAI behind a parked semi‐trailer.  Upon investigation,  this staining actually appears to be the expression of fly ash at the surface where the gravel cover is thin  or missing.  Samples of the stained area soil (“Truck‐stain”) were collected at the surface (3 inches) and at  a depth of 3 feet bls, at the base of the fly ash and just above native soil.  PID readings were 0 ppm in the  entire interval tested.  Both samples were submitted for analysis of TPH‐DRO.       A green drum has been placed on its side, with bungs removed, at the south end of the Site, as noted in  the ESAI.  The green 55 gallon drum contained an open spout with a small amount of unknown residue on     360 Linden Street‐LESAII                        2  the drum and ground surface.  The photoionization detector (PID) registered a detection of 10 parts per  million (ppm) inside the drum.  A soil sample (“drum‐soil”) was collected below the open drum and  analyzed for volatile organic compounds (VOCs) and total petroleum hydrocarbons‐gasoline range  organics (TPH‐GRO) to determine if the contents of the drum had leaked to the soil.    Two oil stained areas were identified in the gravel parking area generally west of piezometer PZ‐2.  The  surface areas of the visible stains were roughly five square feet.  Staining appeared to be associated with  leaked fuel or oils from previously parked trucks or equipment.  Samples were collected in the upper 3  inches (surface samples) at both locations (Stain‐2 @ 3” and Stain‐3 @ 3”).  Surface soils at both locations  had a strong hydrocarbon odor and registered 100 ppm on the PID.  After collection of each surface  sample, a hand auger was used to advance a boring at each location to a depth of 5 feet bls.   Samples  were collected at 5 feet bls (Stain‐2 @ 5’ and Stain‐3 @ 5’), to determine if the apparent surface  contamination had migrated to depth.  All of the soil samples were submitted for analysis of TPH‐GRO.    Samples of fly ash were collected near the locations of former EEC geotechnical borings B1 (B1‐Soil) and  B2 (B2‐Soil) where cinders and fly ash were identified in the boring logs at depths up to 4 feet. Samples of  the fly ash were collected from 2 to 3 feet at each location.  Each of the fly ash samples were submitted  for analysis of total petroleum hydrocarbons‐diesel range organics (TPH‐DRO), Resource Conservation  Recovery Act (RCRA) metals and asbestos.    All soil sample locations are presented in Figure 1.    2.2 Groundwater Investigation  The piezometers were opened and a Solinist water level indicator was lowered into the wells to determine  if water was present.  Both piezometers had water.  PZ‐1 is located at the location of former EEC soil  boring B4.  PZ‐1 has a total depth of 16.29 feet with water at 15.15 feet (all measured from top of PVC  casing).  Sufficient water was present to bail the well, though the water was muddy and sandy.  No attempt  was made to develop the well.  Samples were collected using a half‐inch bailer.  Three volatile organic  analysis (VOA) vials were collected, and submitted for analysis of VOCs.    PZ‐2 is located at the location of former EEC boring B2.  PZ‐2 has a TD of 14.29 feet from TOC with water  at 14.0.  With only 0.29 feet of water, the well could not be bailed.  Sampling was performed using new  quarter‐inch tubing and suction.  Two VOA vials were collected for analysis of VOCs.    2.3 Floor Drain Investigation  The building identified as Garage #1 in the ESAI, is basically set up with three bays, or sections.   The  northeast bay is a break room/work room with tables and couches. The middle bay has storage of  numerous tools and equipment.  The southwest bay contains an oil changing area and a floor drain that  runs along the floor parallel to the garage, for most of the length of the bay.  Figure 2 shows the layout of  Garage #1 with items of interest.  The garage had a strong hydrocarbon odor.  PID readings in the middle  bay were steady around 2.7 ppm.  PID readings in the southwest bay were steady around 4.5 ppm.    The floor drain is approximately 8 inches deep, and is covered with a steel grate along its full length.  The  drain floor was dry and filled with dirt and small debris.  There was no moist sludge in the floor of the  drain to sample.  There is a pipe that exits the drain, beneath the concrete floor, at the northeast corner.   The pipe runs under the concrete floor toward a manhole located in the northeast corner of the garage  bay.  The manhole is a 2 foot diameter steel cover embossed with the words "storm drain".  The cover  was removed to reveal what appears to be an oil/water separator (OWS) or vault.  The vault was full of  oil with a PID reading above the oil of 20 ppm.       360 Linden Street‐LESAII                        3  A sample of the oil/water was collected, and submitted for analysis of VOCs.  An attempt was made to dip  a sample container below the oil water interface to collect a water sample.  However, to the depth  investigated (about 1 foot) there was only oil.  Analysis as a water sample may not be possible due to the  oil matrix.      The OWS may outlet toward Willow Street where a storm drain runs on the west side of the road.  There  may be a sanitary sewer there as well.  A bathroom is located on the other side of the garage wall (middle  bay), and may share common plumbing to the sanitary sewer with the OWS.  It is also possible that the  OWS has no outlet and was pumped as needed.   ERC did not further investigate or confirm the outlet  connections.     2.4 Samples Collected  Table 1 presents a list of all samples collected as part of the LESAII.  The table lists the samples collected,  the sample matrix, the analyses requested, and the analytical methods performed.   Comments are  provided for each sample indicating any PID detections, or other relevant sampling details.    3.0 INITIAL TESTING INVESTIGATION RESULTS    Results of the initial LESAII sample testing are presented in Table 2.  All soil sample locations are shown in  Figure 1. All soil and groundwater samples were submitted to TestAmerica laboratory located in Arvada,  Colorado for analyses.  Samples for analysis of asbestos were submitted to Reservoirs Environmental, Inc.  laboratory located in Denver, Colorado.   A discussion of the sample results is provided in the following  sections.    3.1 Soil Sampling  Areas of surface soil staining were evaluated.  The area of apparent staining located behind a parked semi‐ trailer (Truck‐Stain) was sampled at the surface (3 inches) and at a depth of 3 feet.  No TPH was detected  in the surface sample.   TPH diesel and motor oil fractions were detected in the 3 foot sample at  concentrations of 44 mg/kg and 71 mg/kg, respectively.  The total TPH concentration is well below the  Colorado Department of Labor and Employment – Oil Inspection Section (OIS) soil screening level of 500  mg/Kg.    A soil sample was collected beneath the stain in front of the tipped over 55‐gallon drum at a depth of 6  inches in moist silty sand.  The sample was submitted for analysis of VOCs and TPH‐GRO.  No VOCS or TPH  was detected in the sample.     Soil samples were collected at two areas (Stain 2 and Stain 3).  Samples were collected at a depth of 3  inches at both locations.   TPH‐GRO was detected at concentrations of 28 mg/Kg and 21 mg/kg at Stains  #2 and #3, respectively.   These TPH concentrations are well below the OIS screening standard.  Samples  were collected at a depth of 5 feet bls at both locations to determine if contamination had migrated  vertically.  TPH‐GRO was not detected in either of the deeper samples.    Soil samples were collected near the locations of two former geotechnical borings (B1 and B2).  No  asbestos was detected in either of the soil samples composed mostly of fly ash.  TPH diesel range was  detected in the B1 and B2 soils at concentrations of 67 and 52 mg/kg, respectively.  TPH motor oil range  was detected in the B1 and B2 soils at concentrations of 92 and 96 mg/kg, respectively.  Total TPH  concentrations at both locations are well below the OIS screening standard.     360 Linden Street‐LESAII                        4    Both B1 and B2 soil samples were submitted for analysis of RCRA metals.  As shown in Table 2, all metals  detections were below the associated EPA Regional Screening Levels for residential soils, with the  exception of arsenic.    3.2 Groundwater Sampling  Samples were collected from the two piezometers installed by Earth Engineering Consultants, LLC (EEC).   Each well was opened and a PID reading was taken over the top of the open well.  No PID detections were  noted in either well.  Both piezometers had water.      Assuming that groundwater generally flows toward the Poudre River east of the Site, PZ‐1 would be  considered as the up gradient well for the Site and PZ‐2 would represent conditions down gradient of at  least a portion of the Site.   Several VOCs were detected in groundwater sample PZ‐1 at very low  concentrations, as shown in Table 2.  Detections for benzene, chloroform, chloromethane, and toluene  were reported at estimated concentrations, less than standard reporting limits (J flagged by TestAmerica),  and well below designated MCLs or tap water standards.  PCE was detected at a concentration of 3.0 ug/L,  which is below the MCL of 5 ug/L.  No VOCs were detected in well PZ‐2.    3.3 Floor Drain Investigation  A sample was collected from the OWS.   Because of the oil matrix, TestAmerica had to analyze the sample  as a waste, rather than as a water sample.  Results for the analysis were provided in units of ug/Kg.   Toluene, m/p‐xylene, and o‐xylene were each detected in the oil samples at estimated concentrations (J  values).  The detections were compared to EPA groundwater protection concentrations for soils.  The  concentration of toluene in the oil exceeded the screening standard for groundwater protection by  approximately 20 percent.    4.0 DISCUSSION    4.1 Soils  Detections of TPH‐GRO were found in surface soils where obvious staining from leaking equipment or  spills was evident.  These detections were well below the 500 mg/kg OIS screening standard.  Deeper soil  samples collected at these same locations did not have any TPH detections, indicating that the surface  contamination has not been mobilized to deeper soils.    TPH diesel and motor oil fractions were detected in the soils consisting of predominantly fly ash at  consistent concentrations, regardless of the location.   Detections of TPH in the fly ash/soil samples  submitted are well below the 500 mg/kg screening level.  It is possible that some percentage of un‐ combusted hydrocarbon that includes these carbon ranges is present in the fly ash, as it would be found  in the original coal.  No asbestos was detected in the fly ash samples.    Detections of RCRA metals in the fly ash are expected, as these metals are present in coal at various  concentrations, depending on the original coal bed makeup.  Toxic constituents in fly ash may include one  or more of the following elements or substances found in trace quantities (up to hundreds ppm): arsenic,  beryllium, boron, cadmium, chromium, hexavalent chromium, cobalt, lead, manganese, mercury,  molybdenum, selenium, strontium, thallium, and vanadium (Managing Coal Combustion Residues in  Mines, Committee on Mine Placement of Coal Combustion Wastes, National Research Council of the  National Academies, 2006).       360 Linden Street‐LESAII                        5  Arsenic concentrations in both fly ash samples exceed screening standard.   Background arsenic  concentrations in Colorado soils also typically exceed the screening standard.  The Colorado Department  of Health and Environment (CDPHE) notes that the 95% UCLM (upper control limit of the mean) for arsenic  in “Urban Mixed Use” settings is 19 mg/Kg, and that the average for all land uses is 11 mg/Kg.  According  to the CDPHE document, “Risk Management Guidance for Evaluating Arsenic Concentrations in Soil” (June  2011):    If arsenic concentrations at your site are lower than 0.39 mg/kg, the Division will require no further  action to address arsenic in soil. If arsenic concentrations are lower than 11 mg/kg (the average  of the 95% UCLM of background concentrations found by the U.S. EPA in Colorado), and releases  of arsenic could not have occurred at the site, based on historical data or process knowledge, the  Division will require no further action to address arsenic in soil. If arsenic concentrations are  greater than 0.39 mg/kg, and the available information suggests that a release of arsenic could  have occurred at the site, the Division will require additional evaluation of the data and possibly  additional sampling to determine whether corrective measures for arsenic are required. This  evaluation may include a site specific background study with sampling from offsite locations,  and/or additional sampling in areas of the site where activities that could have contributed to  environmental contamination never occurred.    4.2 Groundwater  Based on the two piezometers sampled, groundwater contamination at the Site does not appear to be an  issue.  Low level VOCs were detected in the presumed up gradient sample, though no action levels were  exceeded.  No VOCs were detected in the presumed down gradient sample, even though this sample is in  close proximity to surface soil staining where TPH‐GRO was detected.  These results, as well as those from  the deeper soil samples, support the conclusion that surface contamination associated with minor spills  is not migrating into groundwater.    4.3 Floor drain  The floor drain in Garage #1 drains to an apparent OWS.  Based on analysis, the material in the OWS is oil  with a mix of fuel related VOCs.  If this oil was released to the ground surface, it would present a risk to  groundwater, based on the detected toluene concentration.    4.4 Initial Testing Recommendations  The arsenic concentrations detected in the two fly ash samples analyzed for RCRA metals are at levels that  require additional evaluation, follow up and/or potential coordination/verification with the CDPHE.  Both  arsenic concentrations (5.3 and 14 mg/kg) are less than the 19 mg/kg level that CDPHE has identified as  the 95% UCLM in urban mixed use settings.  The arsenic concentration in sample B1‐Soil just exceeds the  11 mg/kg 95% UCLM average for samples collected in Colorado.  The fly ash buried at the Site does present  a source as a potential arsenic release.  Based on the initial testing ERC recommends that a contact should  be initiated with CDPHE, through their voluntary cleanup program, to determine what, if any further  investigation should be performed regarding the arsenic in fly ash or an for an approach to determine  compliance and closure.  The arsenic concentrations are very close to the level that may indicate that no  further action would be required, however we recommend clarification from the CDPHE.           360 Linden Street‐LESAII                        6  5.0 ADDITIONAL TESTING    As noted in Section 4.4 elevated detections of arsenic in the fly ash require additional testing and potential  coordination with agencies.   ERC initiated a discussion with Fonda Apostolopoulos with the CDPHE  Voluntary Cleanup Program, regarding arsenic detections in the fly ash.  The discussion was not site  specific, but Mr. Apostolopoulos provided generalized recommendations.  He indicated that samples for  dissolved metals in the shallow groundwater should be collected to determine if metals present in the fly  ash, at concentrations potentially above background, are impacting groundwater.  Additional sampling  was also recommended to characterize metals and DRO concentrations in the fly ash, to support potential  disposal of the fly ash at a landfill.  According to the geotechnical report prepared for the Site, fly ash and  other surface materials present at the Site are not suitable for the proposed building construction, and  will have to be removed.    Additional testing, including Site investigation and sample collection, was conducted by ERC on August 6,  2014.   The northwest half of the Site is proposed for future development that will include a large  subsurface building structure.  The general footprint of the proposed building structure is shown in Figure  3.  As part of this proposed future development, surface soils, fly ash, and fill materials will likely be  excavated.  Shallow groundwater may require pumping to keep the proposed basement dry.   During  excavation, the portion of fill consisting of fly ash should be segregated.  As described in the following  sections additional groundwater, soil, and fly ash samples were collected by ERC as part of this LESAII to  support the potential Site development as well as to better define potential fly ash arsenic concerns.    5.1 Groundwater Sampling  A peristaltic pump was used to collect additional groundwater samples from the two piezometers  previously installed at the Site.  The "up gradient” well (PZ‐1) was very slow to recharge and took a couple  of hours to collect 500 milliliters.  The "down gradient" well (PZ‐2) had less water, but the sample bottle  filled in a couple of minutes.  Samples were field filtered for analysis of dissolved RCRA metals.    Subsequent to the June 24, 2014 testing, EEC installed five additional temporary wells at locations around  the proposed building footprint on the Site.  The wells were screened and completed in the shallow  sandstone aquifer.  These wells were installed to investigate groundwater depths in the sandstone relative  to the proposed depths of the proposed development.  Future groundwater samples could be collected  from these wells, if characterization of the deeper aquifer was required, however were not collected as  part of this additional testing.  Two of the bedrock wells are installed near the two piezometers.  Based  on water levels measured in adjacent alluvial and bedrock wells, it appears that the alluvial water at the  Site is separate from the site bedrock groundwater.    The piezometers are completed into the thin shallow alluvial groundwater at the Site, that would most  likely be impacted by any contaminants present in shallow soils and fly ash.  These piezometers (PZ‐1 and  PZ‐2) were sampled for VOCs as part of the initial June 24, 2014 testing.  As follow‐up investigation,  additional samples were again collected from both piezometers for more specific analysis of dissolved  RCRA metals.      5.2 Fly Ash and Soil Sampling  Two additional composite samples (as shown in the two oval outlines) were collected from the six  locations shown in Figure 3, within the proposed development footprint.  Samples were collected using a  hand auger.  All holes were advanced to a depth of 5 feet bls. The western‐most row of three samples all     360 Linden Street‐LESAII                        7  encountered fly ash at depths between approximately 1 to 3 feet bls.  Fly ash material from all three  locations was composited into one sample identified as “WC‐FA” (west composite ‐ fly ash).      The three borings in the eastern‐most row did not encounter fly ash, indicating that the distribution of fly  ash may be limited across the Site.  A composite soil sample from the three eastern borings (EC‐Soil) was  collected.   Both composite samples were submitted for analysis of RCRA metals and TPH fractions.  The  EC‐Soil sample may be representative as a potential background sample for the site.    Four additional soil borings were advanced in the southern half of the Site, and are numbered S1 through  S4 from north to south, as shown in Figure 3.  This portion of the Site is not yet scheduled for future  development.  The soils encountered at each of these locations consisted of very hard packed road base  material at the surface (6‐8 inches), overlying possible gravelly fill, or re‐graded material, overlying native  silty sand to five feet.  No obvious fly ash was encountered at any of these locations.  Locations S3 and S4  did have some dark grey material that could have been fly ash, maybe re‐worked, in the first foot below  the surface.  Samples of this shallow soil were collected at these two locations for analysis of RCRA metals  and TPH.    6.0 ADDITIONAL TESTING DISCUSSION    6.1 Groundwater  Based on the two additional piezometers sampled, groundwater contamination in the alluvial aquifer at  the Site does not appear to be an issue.  No dissolved metals were detected in the groundwater at  concentrations exceeding applicable standards.  In particular, arsenic, which is detected in fly ash and soil  samples above EPA screening standards, was not detected in the groundwater.    6.2 Fly Ash and Soils  The additional testing was performed, in part, to get a better understating of metals concentrations in the  fly ash, particularly for arsenic, which exceeded the EPA RSL and CDPHE guidance standards in the initial  June 24, 2014 sampling.  The arsenic concentration in the composite fly ash sample is 7.1 mg/kg.  The  average arsenic concentration for all of the fly ash and soil samples submitted for RCRA metals analysis in  the LESAII investigation (six samples) is 7.2 mg/kg.  The standard deviation of the arsenic concentrations  is 4.2 mg/kg and the range of arsenic concentration is 2.7 to 14 mg/kg.  Similar to the results for the TPH  samples, the arsenic concentrations are not significantly different in the soil samples then they are in the  fly ash.   It is possible that all arsenic concentrations may be representative of local and regional  background conditions.   Background arsenic concentrations in Colorado soils typically exceed the  screening standards, and the average arsenic concentration for all land uses is 11 mg/Kg.  The average  arsenic concentration for the samples collected at the Site is less than the Colorado average for all land  uses.    According to the CDPHE document, “Risk Management Guidance for Evaluating Arsenic Concentrations in  Soil” (June 2011):    If arsenic concentrations are greater than 0.39 mg/kg, and the available information suggests that  a release of arsenic could have occurred at the site, the Division will require additional evaluation  of the data and possibly additional sampling to determine whether corrective measures for arsenic  are required. This evaluation may include a site specific background study with sampling from     360 Linden Street‐LESAII                        8  offsite locations, and/or additional sampling in areas of the site where activities that could have  contributed to environmental contamination never occurred.    ERC believes that the sampling performed as part of this LESAII has satisfied the intent listed in the  CDPHHE paragraph summarized above.  Due to the presence of fly ash on the Site, it is possible that a  release could have occurred.  Groundwater was investigated, and there is no evidence of an impact or  release from arsenic.   Site samples that did not contain fly ash were evaluated, and the arsenic  concentrations in these samples were not significantly different from those in the fly ash.  Fly ash does  not appear to be a significant source of metals relative to other Site soils.    The sample collected in shallow soil at the S3 location contained lead at a concentration exceeding the  RSL.  This appears to be an isolated occurrence.  Areas of obvious surface staining should be excavated  when the bulk of the future proposed development excavation work is performed.  It may be that much  of the existing surface material will be excavated at some time, regardless of staining, to be replaced with  better engineered surface toppings.          360 Linden Street‐LESAII                        9  7.0  CONCLUSIONS AND RECOMMENDATIONS    Based on the results of this LESAII, there does not appear to be contamination in soil or groundwater at  the Site that presents a regulatory concern.     Arsenic detections in fly ash exceeded CDPHE action levels in the initial investigation.  Because the fly  ash is not native to the Site, it was initially viewed as a possible contaminant, from which a release could  have occurred.  Therefore, in accordance with CDPHE guidance, additional investigation of groundwater,  soil, and fly ash was performed.  Arsenic was not detected in the groundwater.  The concentrations of  arsenic detected in soil and fly ash are not significantly different.  Average arsenic concentrations for all  samples collected are well within the range of average background concentrations for the state of  Colorado.  Therefore, the fly ash is not considered a significant source of contamination and additional  sampling and investigation is not recommended at this time.    It is recommended that fly ash be disposed of during future Site development.  Segregated fly ash and  additional small quantities of surface stained soils should also be excavated and disposed as a matter of  good environmental practice.  The Waste Management Ault Landfill, which is located locally on Highway  C14, was contacted regarding disposal of fly ash and soils. The Ault landfill can take fly ash, and does so  routinely.  The data that has been generated in this LESAII should be sufficient to profile the fly ash and  any soils for disposal at the Ault landfill.   The profile information is submitted through the Waste  Management website by the person who is billed for the disposal.    ERC recommends that the OWS should be pumped out so that the plumbing connections can be  evaluated. If the OWS is correctly plumbed, such that no release to the environment is likely, no further  action should be required.  If there is no outlet from the OWS, it may have been pumped out on an as  needed basis.   Regardless of the plumbing, the integrity of the OWS vault should be inspected to  determine if any leaks from the vault are likely.    As noted in the ESAI, there are numerous drums and containers stored in the garages at the Site that  contain lubricants, solvents, and other materials that need to be properly handled and removed from the  Site.      Ecological Resource Consultants, Inc.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 06/25/2014; the samples arrived in good condition, properly preserved and on ice. The temperature of the cooler at receipt was 5.5 C. VOLATILE ORGANIC COMPOUNDS (GC-MS) - METHOD 8260B (SO) Sample OWS (280-57089-12)[10X] required dilution prior to analysis due to matrix interference. The samples were re-analyzed with similar results. The reporting limits have been adjusted accordingly. Surrogates 4-Bromofluorobenzene and Toluene-d8 were recovered below the QC control limits in sample OWS (280-57089-12). This anomaly is due to obvious matrix interferences; therefore, corrective action is deemed unnecessary. Sample data should be considered biased low. The matrix spike / matrix spike duplicate (MS/MSD) samples associated with analysis batch 280-232218 were performed on OWS (280-57089-12) and exhibited recoveries outside control limits and exceeded RPD values for multiple analytes due to matrix interference. In addition, the MS/MSD exhibited surrogate recoveries outside control limits. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. The matrix spike / matrix spike duplicate (MS/MSD) samples associated with analysis batch 280-232943 were performed on a sample from another job and exhibited recoveries outside control limits for several anaytes, biased low. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. VOLATILE ORGANIC COMPOUNDS (GC-MS) - METHOD 8260B (AQ) The sample containers for samples PZ-1 (280-57089-1) and PZ-2 (280-57089-2) were preserved with HCl. However, the sample pH was measured as 7. The method requires that samples be preserved to a pH <2. The matrix spike / matrix spike duplicate (MS/MSD) samples associated with analysis batch 280-233383 were performed on PZ-1 (280-57089-1) and the MS exhibited recoveries outside control limits for Acetone, biased low. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. GASOLINE RANGE ORGANICS (GRO) - METHOD 8015B Samples STAIN-2@3'' (280-57089-4) and STAIN-3@3'' (280-57089-10) were diluted 2X due to the abundance of non-target analytes. The chromatograms indicate a very high concentration of non-target analytes eluting just after the retention time for 1,2,4-trimethylbenzene, which is the retention time marker for the end of the gasoline range. Similar abundances of non-target analytes just beyond the GRO range have been known to contribute to baseline rise in subsequent analyses; therefore, the dilutions were reported and the samples TestAmerica DenverPage 3 of 47 7/18/2014 1 2 3 4 5 6 7 8 9 10 11 12 13 Case Narrative Client: Nankoweep Environmental Consulting TestAmerica Job ID: 280-57089-1 Project/Site: 360 LINDEN Job ID: 280-57089-1 (Continued) Laboratory: TestAmerica Denver (Continued) were not re-analyzed at a lesser dilution. The reporting limits have been adjusted accordingly. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. DIESEL RANGE ORGANICS - METHOD 8015B The matrix spike / matrix spike duplicate (MS/MSD) samples associated with analysis batch 280-232710 were performed on B1-SOIL (280-57089-6) and exhibited recoveries outside control limits, biased low, for Diesel Range Organics. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. TOTAL METALS - METHOD 6010B/7471A The laboratory noted; sample B1-SOIL (280-57089-6) was extremely reactive with hydrogen peroxide. The matrix spike / matrix spike duplicate (MS/MSD) samples associated with analysis batch 280-234117 were performed on B1-SOIL (280-57089-6) and exhibited recoveries outside control limits for Lead and Silver. In addition, RPD values were exceeded for Lead and Silver. The presence of the '4' qualifier indicates analytes where the concentration in the unspiked sample exceeded four times the spiking amount. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. The matrix spike / matrix spike duplicate (MS/MSD) samples associated with analysis batch 280-232815 were performed on a sample from another job and exhibited recoveries outside control limits for Mercury, biased low. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The samples were received on 8/7/2014; the samples arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 0.7º C. TestAmerica Denver subcontracted the requested Total and Dissolved Metals to TestAmerica Savannah located at 5102 LaRoche Avenue, Savannah, GA 31404. Per client request, sample WC-FA as listed on the associated chain-of-custody, was placed "on hold" pending further instruction. This sample was logged under separate cover in Job 280-58748-3. DIESEL RANGE ORGANICS (GC) - METHOD 8015B Samples EC-SOIL (280-58748-4), S3 (280-58748-5) and S4 (280-58748-6) were analyzed for diesel range organics in accordance with EPA SW-846 Method 8015B - DRO. Surrogate o-Terphenyl was recovered outside the control limits in sample S4 (280-58748-6). Evidence of matrix interference is present; therefore, re-extraction and/or re-analysis was not performed. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. TOTAL METALS (ICP) - METHOD 6010B Samples EC-SOIL (280-58748-4), S3 (280-58748-5) and S4 (280-58748-6) were analyzed for total metals in accordance with EPA SW-846 Method 6010B. The matrix spike / matrix spike duplicate (MS/MSD) associated with analysis batch 680-344675 exhibited a MS recovery outside control limits for Lead. The MSD exhibited spike recoveries outside control limits for Barium and Lead. The presence of the '4' qualifier in the report indicates analytes where the concentration in the unspiked sample exceeded four times the spiking amount. In addition, the RPD was outside the control limits for Lead. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. TOTAL MERCURY (CVAA) - METHOD 7471A Samples EC-SOIL (280-58748-4), S3 (280-58748-5) and S4 (280-58748-6) were analyzed for total mercury in accordance with EPA SW-846 Method 7471A.

In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required. Calculations are performed before rounding to avoid round-off errors in calculated results. All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below. RECEIPT The sample was received on 8/7/2014; the sample arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 0.7º C. TestAmerica Denver subcontracted the requested RCRA Metals to TestAmerica Savannah located at 5102 LaRoche Avenue, Savannah, GA 31404. A handwritten note on the chain-of-custody read "Hold sample in baggie for WC-FA". The client was contacted via a telephone conversation on 8/7/2014 and asked to confirm if he wanted the laboratory to log sample WC-FA "on hold". The client instructed the laboratory to "hold the sample in the baggie for WC-FA". During that conversation, it wasn't communicated to the laboratory that soil jars were also submitted for this sample in order for the laboratory to proceed with the requested DRO and RCRA Metals analysis. Therefore, the entire sample was logged "on hold" as the knowledge of additional containers was not mentioned. A Sample Acknowledgment Report indicating that the entire sample analyses of WC-FA was logged "on hold" was sent to the client on 8/07/2014. The client contacted the laboratory when he received his final report (Job 280-58748-1) and inquired as to where the sample results for WC-FA were? It was at that time that it was discovered that there had been a misunderstanding between what was communicated to the laboratory and what the client acutally wanted. The client then instructed the laboratory to proceed with the DRO and RCRA Metals analysis using the volume from the soil jars. Unfortunately, by that time, the DRO extraction hold time had expired. The client authorized the laboratory to proceed with the requested DRO analysis outside of hold. No other discrepancies were noted. DIESEL RANGE ORGANICS (GC) - METHOD 8015B Sample WC-FA (280-58748-3) was analyzed for diesel range organics in accordance with EPA SW-846 Method 8015B - DRO. Surrogate o-Terphenyl was recovered outside the control limits, biased high, in sample WC-FA (280-58748-3). Surrogate o-Terphenyl was also recovered outside the control limits, biased high, in the MS and MSD performed on sample WC-FA (280-58748-3), indicating matrix interference as the cause for the surrogate recovery outlier, therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. TOTAL RCRA METALS (ICP) - METHOD 6010B Sample WC-FA (280-58748-3) was analyzed for total metals in accordance with EPA SW-846 Method 6010B. TestAmerica DenverPage 3 of 18 9/2/2014 1 2 3 4 5 6 7 8 9 10 11 12 13 Case Narrative Client: Nankoweep Environmental Consulting TestAmerica Job ID: 280-58748-3 Project/Site: Standard Analysis Job ID: 280-58748-3 (Continued) Laboratory: TestAmerica Denver (Continued) The accuracy and precision of the MS/MSD performed on sample WC-FA (280-58748-3) could not be reliably evaluated for Barium and Lead, as the concentrations present in the parent sample were 4 times greater than the matrix spike concentration. The MS aliquot of the MS/MSD exhibited spike recoveries outside control limits, biased high for Arsenic and Silver. In addition, Barium Lead and Silver exceeded the RPD control limits. The acceptable LCS analysis data indicated that the analytical system was operating within control; therefore, corrective action is deemed unnecessary. No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page. TOTAL MERCURY (CVAA) - METHOD 7471A Sample WC-FA (280-58748-3) was analyzed for total mercury in accordance with EPA SW-846 Method 7471A. No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.
