Forsythe National Wildlife Refuge, New Jersey, to environmental health stressors: U.S. Geological Survey data release, https://doi.org/10.5066/F7765CH1 Online_Linkage: https://doi.org/10.5066/F7765CH1 Description: Abstract: Natural and anthropogenic contaminants, pathogens, and viruses are found in soils and sediments throughout the United States. Enhanced dispersion and concentration of these environmental health stressors in coastal regions can result from sea level rise and storm-derived disturbances. The combination of existing environmental health stressors and those mobilized by natural or anthropogenic disasters could adversely impact the health and resilience of coastal communities and ecosystems. This dataset displays the exposure potential to environmental health stressors in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA. Exposure potential is calculated with the Sediment-bound Contaminant Resiliency and Response (SCoRR) ranking system (Reilly and others, 2015) designed to define baseline and post-event sediment-bound environmental health stressors. Facilities obtained from the Environmental Protection Agency’s (EPA) Toxic Release Inventory (TRI) and Facility Registry Service (FRS) databases were ranked based on their potential contaminant hazard. Ranks were based in part on previous work by Olsen and others (2013), literature reviews, and an expert review panel. A 2000 meter search radius was used to identify nearby ranked facility locations. As part of the Hurricane Sandy Science Plan, the U.S. Geological Survey has started a Wetland Synthesis Project to expand National Assessment of Coastal Change Hazards and forecast products to coastal wetlands. The intent is to provide federal, state, and local managers with tools to estimate their vulnerability and ecosystem service potential. For this purpose, the response and resilience of coastal wetlands to physical factors need to be assessed in terms of the ensuing change to their vulnerability and ecosystem services. EBFNWR was selected as a pilot study area. Purpose: Analysis of environmental health stressors is part of a comprehensive assessment to identify the factors and their weights in determining the vulnerability and resiliency of salt marshes. This polygon dataset facilitates quantifying vulnerability to contaminant hazards in the EBFNWR salt marsh complex. The results are summarized over the previously determined conceptual salt marsh unit polygons (Defne and Ganju, 2016).

Exposure potential to environmental health stressors is calculated with the SCoRR strategy for a uniform grid with 0.003 degrees (~300 meters) resolution and resampled at a higher resolution of 0.0003 degrees (~30 meters) prior to averaging over each marsh unit. Logical_Consistency_Report: By definition SCoRR ranks cannot be a negative real number. Final values for each marsh unit were verified to be either zero or a positive real number. Completeness_Report: The boundaries of this dataset were created by expanding the outline boundaries of polygons created with a 250 meter exterior buffer around the source data, conceptual marsh units, which include: 1) Marsh Salt, 2) Wetland Scrub Shrub Salt, and 3) channels of Open Water Salt that are not wider than 50 meters. Any polygons with an area smaller than 50 square meters were omitted in the source dataset. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal accuracy for the polygon boundaries is inherited from the source layer, conceptual marsh units, and considered to be greater than 3 meters. The point cloud used for calculating exposure potential had ~300-meter resolution that was interpolated over a 30-meter raster. The raster dataset was resampled at 3 meter resolution to enhance the conformity with the marsh unit boundaries prior to calculating zonal statistics.

Jones following the SCoRR strategy (Reilly and others, 2015). ArcMap (ver. 10.2) and tools from ArcToolbox were used for analysis unless otherwise stated. Names of specific tools used are given in CAPITAL letters (any critical parameters used is given in parentheses, separated by a semicolon, immediately after the tool name). Input and output file names are provided in [square brackets] when necessary. Apply SCoRR ranks to the gridded array of points [contPts.xls]. a) Generate the list for facilities of concern from EPA's Toxic Release Inventory (TRI) data, and EPA's Facility Registry Service (FRS) data. TRI data was downloaded from https://www.epa.gov/toxics-release-inventory-tri-program/tri-basic-data-files-calendar-years-1987-2015 using the drop down menus for the year of interest and select the state. For this work 2013 data for the state of New Jersey was used. Each facility was assigned a rank value from 1 to 4 indicating its 'perceived contaminant hazard' based on i) a modified version of ranked contaminants from Olsen et al. 2013 (Reilly and others, 2015; Table 1), or ii) paneled expert opinion following methods outlined in Olsen et al. 2013. FRS data was downloaded from https://www.epa.gov/enviro/epa-frs-facilities-state-single-file-csv-download for New Jersey. Each facility was assigned a rank value from 1 to 4 based upon a questionnaire administered to the same expert panel mentioned above. Three attribute fields were utilized to assess the perceived contaminant hazard of each FRS facility: Environmental Program Type, Environmental Interest Type, and Site Type. Each of these fields provides details about regulations, uses, and potential hazards relevant to each facility. When relevant, historic storm vulnerabilities were used to then weight each ranked FRS and TRI facility. Storm vulnerability datasets included Federal Emergency Management Agency's (FEMA) 100-year flood zones, National Oceanic and Atmospheric Administration’ Sea, Lake, and Overland Surges from Hurricanes (NOAA SLOSH) model-based inundation extents for hurricanes of category 1 to 5 in magnitude, and probabilities of storm impacts based on National Weather Service’s International Best Track Archive for Climate Stewardship (NWS IBTrACS) data. Overlay analysis was used to identify all facilities falling within 1 or more of these storm vulnerabilities. Equation 1 in Reilly and others (2015) was used to then weight each facility's perceived contaminant hazard rank based on the number of intersected storm vulnerabilities. b) Create a shapefile from the point coordinates and DEFINE PROJECTION(Coordinate System=WGS 84) as World Geodetic System 1984. c) GENERATE NEAR TABLE(Input Features=IN_FID; Near Features=NEAR_FID; Search radius= 2000 m) to identify facilities of concern within 2000 m of each point. Separate tables were generated for the TRI and FRS facilities. These were then recombined later during the inverse distance weighting procedure to arrive at the final rank at each location. d) Tables are imported into R software package and joined using the fields 'IN_FID' and 'NEAR_FID' to link facility attributes with each location using near table output. e) SCoRR rank at each location is calculated using the inverse distance-weighted average rank equation (Reilly and others, 2015; Equation 2) within a search radius of 2000 meters, based on the storm vulnerability-weighted potential contaminant hazard rank for each facility, and the distance to the facility location.

A higher SCoRR rank indicates higher exposure potential to environmental health stressors. Raster cells that do not have a facility within a 2000 meter proximity are assigned a SCoRR rank of zero prior to clipping to the processing extent. Decimal values in the attribute table are a result of double precision calculations while significant digits are considered in defining the attribute measurement resolutions. Therefore, the smallest unit increment for exposure potential (SCoRR) values can be assumed to be a practical value such as 0.01.
