DRAFTwest of the railroad tracks along the northeastern shoreline ofOnondaga Lake. Onondaga Lake forms the western border of thiswetland. An abrupt rise in topography (i.e., berm and railroad bed)defines the eastern border of the wetland, and Ley Creek defines thenorthern boundary of this wetland area. This portion of SYW-12 is acombination of a monoculture stand of Phragmites and forestedfloodplain that comprise an overstory of predominantly easterncottonwood trees. As this wetland is contiguous with the lake, thetransitional area between the palustrine and lacustrine habitatsconsisted mostly of gravel-cobble shoreline and Solvay waste shoreline.Soils mapped for this wetland cell included made land (Ma) and cut andfill land (CFL) soils (USSCS 1977). According to USSCS (1977), Maconsists predominantly of bed areas of waste material, which may ormay not be covered with vegetation and CFL soils vary widely withinOnondaga County.The portions of SYW-12 identified and delineated by O’Brien & Gere in2008 consist of two sub-wetlands (WL 2 and WL 3) south of Ley Creekand east of the railroad tracks that border WL 1. WL 2 is a 1.1-acretriangular-shaped area bordered on two sides by railroad tracks and bya dirt road on the third side. This delineated wetland is a monoculture ofPhragmites. WL 3 is a 0.26-acre narrow strip of Phragmites bordered byrailroad tracks and a dirt road.Analytical samples for SYW-12 were collected during the summer of2000 as part of the Onondaga Lake RI. Four locations were analyzedfor VOCs, SVOCs, pesticides, polychlorinated biphenyls (PCBs),metals, total organic carbon (TOC), and percent solids. Resultsindicated the presence of each of these analytes at one or more of thefour sample locations (TAMS, 2002a). A wetland subsurfaceinvestigation was performed in May 2000 by C&S Companies (C&S,2001). Thirteen subsurface borings were advanced as part of thisinvestigation. Borings were advanced to characterize subsurface soilsand identify the potential existence of contamination. Soil samples werecollected from the following three intervals:• Interval 1: existing grade to approximately 6 to 12 inchesbelow ground surface (bgs)• Interval 2: from 6 or 12 inches below grade to a depth ofthe proposed finished wetland elevation• Interval 3: from 6 inches immediately above the proposedwetland finished grade elevation to a depth of 18 to 20inches below the proposed wetland finished gradeelevation (C&S, 2001).Samples collected from each of the three sampling intervals wereanalyzed for Target Analyte List (TAL) metals, pH, and total organiccarbon (TOC). Samples collected from Interval 3 were analyzed forTarget Compound List (TCL) VOCs, SVOCs, PCBs, and pesticides.One half of the samples collected from Intervals 1 and 2 were analyzedfor TCL VOCs, SVOCs, PCBs, and pesticides (C&S, 2001).PARSONS | Remedial Design Elements for Habitat Restoration 49
DRAFTSYW-10 is forested wetland locatednear the mouth of Ninemile Creek.A black tar-like layer was observed during the completion of eight of theborings. The black tar-like layer was identified 4 to 12-ft bgs dependingon the borings location and exhibited a “heavy oil-like odor”. The layervaried in thickness from 1 inch to 14 inches depending on location.Samples from the black tar-like layer were analyzed for TCL/TALparameters, pH, and TOC (C&S, 2001).VOCs were detected in six of the soil samples. Constituents includedacetone, ethylbenzene, and xylenes. SVOCs at the site consistedmainly of polycyclic aromatic hydrocarbons (PAH) compounds and wereconsistently detected at concentrations greater than screening criteria.The majority of soil samples exceeded screening criteria for thefollowing metals: aluminum, cadmium, calcium, chromium, copper, iron,magnesium, manganese, and zinc (C&S, 2001).Four additional hand augured holes were advanced and sampled formetals as part of additional investigations (O'Brien & Gere 1995).Arsenic, cadmium, chromium, lead, and mercury were detected in thesesamples.Wetland SYW-10Wetland SYW-10, located along Ninemile Creek near its confluence withOnondaga Lake, is a 27-acre, Class I wetland (Figure 2.4). Thiswetland is divided by I-690. On the lake side of I-690, the wetland isdominated by emergent vegetation and floodplain forest. The wetlandsection on the west side of I-690 is dominated by emergent vegetation(primarily Phragmites). TES conducted a jurisdictional wetlanddelineation at the portion of wetland SYW-10 on the lake side of I-690as part of the Geddes Brook/Ninemile Creek Feasibility Study (Parsons,2005).The portion of the Wetland SYW-10 north of Ninemile Creek, consists ofan approximate 5-acre area, with Onondaga Lake forming its easternborder. An abrupt rise in topography (the I-690 roadbed) defines thewestern border of the wetland, and a rise in typography along thesouthern edge of the wetland just north of Ninemile Creek defines thesouthern boundary. This portion of SYW-10 is predominantly forestedfloodplain that is comprised of an overstory of silver maple, Americanelm (Ulmus americana), and box elder. A monoculture stand ofPhragmites is located on the southeastern portion of Wetland SYW-10at the mouth of Ninemile Creek.Additionally, at the south side of the mouth of Ninemile Creek exists anapproximate 1.5-acre area also consisting of a monoculture stand ofPhragmites which occurs as a delta that extends into the lake. As thesewetlands are contiguous with the lake, the transitional area between theuplands and in-lake habitats consisted mostly of gravel-cobble shorelineand Solvay waste shoreline.The Geddes Brook/Ninemile Creek BERA (TAMS, 2003a) evaluatedsurface soil/sediment samples from SYW-10 collected from 0 to 0.5 feetbelow the surface. Forty-one organic compounds exceeded screeningcriteria in SYW-10 surface soils/sediments. Inorganic constituentsdetected included arsenic, chromium, copper, iron, lead, manganese,PARSONS | Remedial Design Elements for Habitat Restoration 50
