(MSG) completed sediment sampling of the Crosby Lake ponds located at the Toledo Botanical Gardens (TBG) on February 14, 2012 in accordance with MSG s proposal dated January 31, A Site location map (Figure 1) is provided for reference and is included in Attachment A. BACKGROUND We understand that the Crosby Lake ponds at TBG have received a significant accumulation of sediments since they were constructed in the 1980s. Accordingly, restoration of the watershed is anticipated to include not only the removal of the two low-head dams within the TBG property, but also the removal of much of the estimated nearly 29,000 cubic yards of sediment that have accumulated. Very little information related the environmental quality of the sediments was available. Ultimately the plan is to be able to beneficially reuse the sediments on the TBG property. SEDIMENT SAMPLING PROCEDURES On February 14, 2012 MSG completed the sediment sampling outlined in the above referenced proposal at TBG. A two-man crew equipped with shovels, a Ponar sediment sampler, sample containers and a row boat collected five sediment samples. One sample was collected downstream of the southernmost low-head dam. Two samples were collected from the lower pond, where a majority of the sediments have accumulated and are proposed for reuse. One sample was collected from the accumulated sediments in the upper pond and the remaining sample was collected upstream of the TBG property to provide a standard by which to evaluate constituents of interest in the sediment from upstream locations. Sample locations are represented on Figure 2, which is also included in Attachment A. Samples were collected in a manner to minimize the potential of cross-contaminating samples. Samples were collected from the farthest downstream location first; the remaining samples were collected as the crew proceeded upstream. Environmental samples were collected using a Ponar sediment sampler. Each sample was given a unique label with indelible ink and submitted to Pace Analytical Services (Pace) under strict chain-of-custody procedures. Samples for geotechnical analyses were collected with shovels and placed in five-gallon buckets pending transport to MSG s geotechnical laboratory in Canton, Michigan. The results from the geotechnical evaluation of the sediment are being provided under separate cover. Civil Engineering, Surveying and Environmental Consulting

2 LABORATORY ANALYSIS Five environmental quality samples were submitted to Pace s laboratory in Indianapolis, Indiana for analysis by US EPA Method 6010 and 7471 for the eight Resource Conservation and Recovery Act (RCRA) metals, and by US EPA Method 8270 for polynuclear aromatic hydrocarbons (PAHs). The highest reported concentration of arsenic was identified in sediment sample 3 (SED-3) in the lower pond with a concentration of 22.4 mg/kg. The second highest reported concentration of arsenic was identified in sediment sample 2 (SED-2) with a concentration of 12.4 mg/kg. The concentration reported at SED-3 is nearly twice as much as the reported concentration of SED-2. Although there are multiple man-made sources of arsenic (e.g., pesticide, rodenticides, etc.), arsenic is also a naturally-occurring element of the earth s crust and these concentrations of arsenic reported in the sediment samples are not extraordinary for either the Toledo, Ohio area or the Maumee River watershed. In fact the upstream sample location (SED-5) had the third highest reported arsenic concentration at 9.9 mg/kg. Similarly, PAHs may be naturally occurring but also have a number of man-made sources including the incomplete combustion of fossil fuels. A wide number of PAHs were reported to be present at SED-2, SED-4 and SED-5, with the highest concentrations of PAHs reported at SED-4 in the upper pond. Given the urban watershed from which the pond sediments have been derived, the findings of PAHs in the sediments is not surprising. MSG compared the analytical data to the Ohio Voluntary Action Plan (VAP) generic direct-contact standards for carcinogenic and non-carcinogenic chemicals of concern commercial/industrial use category (OAC Rule (C)(3)(c)) and the construction and excavation activities category (OAC Rule (C)(3)(d)) to appropriately evaluate the sediment for re-use. MSG chose to use the VAP commercial/industrial land use standards for comparison of the data as the exposure assumptions that were used to derive these standards are more closely synonymous with recreational exposure scenarios than are the exposure assumptions used to derive the residential VAP standards. No reported concentrations of any constituent exceed any of the standards for the commercial/industrial land use category or the construction and excavation activities category. The analytical summary table is located in Attachment B and a copy of the lab report is located in Attachment C. RECOMMENDATIONS It is MSG s professional opinion that there are no restrictions associated with the beneficial reuse of the sediments on the TBG property based upon these data. Sincerely, William W.

25 QUALIFIERS DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to changes in sample preparation, dilution of the sample aliquot, or moisture content. ND - Not Detected at or above adjusted reporting limit. J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. S - Surrogate 1,2-Diphenylhydrazine (8270 listed analyte) decomposes to Azobenzene. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. ANALYTE QUALIFIERS 1d M0 R1 R2 The sample was analyzed at dilution due to its physical characteristics RRB Matrix spike recovery and/or matrix spike duplicate recovery was outside laboratory control limits.
