This dataset includes 210Pb (dpm g) and bulk carbon (mg/ml) data from four 20-cm sediment cores collected in South Bay, Virginia. Two of the cores were collected in 2011, one from within the restored Zostera marina (eelgrass) meadow and one from a nearby bare site. The other two cores were collected in 2014 from a different meadow site and a different bare site. Both meadow cores were collected within original restoration seed plots. The SB-5 bare core was collected north of the restored meadow. The 2-bare core was collected west of the meadow, near Man and Boy Channel. 210Pb and carbon profiles from the meadow sites were used to establish meadow carbon accumulation rates in 2011 and 2014, respectively. Bare areas in this system appear to be non-depositional. Excess 210Pb was not observed in the profiles from the two bare cores.

Although lead has been associated with hearing loss in occupational settings and in children, little epidemiologic research has been conducted on the impact of cumulative lead exposure on age-related hearing loss in the general population. We determined whether bone lead levels, a marker of cumulative lead exposure, are associated with decreased hearing ability in 448 men from the Normative Aging Study, seen between 1962 and 1996 (2264 total observations). Air conduction hearing thresholds were measured at 0.25-8 kHz and pure-tone averages (PTA) (mean of 0.5, 1, 2 and 4 kHz) were computed. Tibia and patella lead levels were measured using K X-ray fluorescence between 1991 and 1996. In cross-sectional analyses, after adjusting for potential confounders including occupational noise, patella lead levels were significantly associated with poorer hearing thresholds at 2, 3, 4, 6 and 8 kHz and PTA. The odds of hearing loss significantly increased with patella lead levels. We also found significant positive associations between tibia lead and the rate change in hearing thresholds at 1, 2, and 8 kHz and PTA in longitudinal analyses. Our results suggest that chronic low-level lead exposure may be an important risk factor for age-related hearing loss and reduction of lead exposure could help prevent or delay development of age-related hearing loss.

This data release includes whole rock geochemical data, and uranium-lead isotopic data collected by both Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and Sensitive High Resolution Ion Microprobe-Reverse Geometry (SHRIMP-RG) methods. Whole rock geochemistry was collected by Activation Laboratories in Ancaster, Ontario. LA-ICP-MS data was collected at the PLASMA at the USGS in Denver, Colorado. SHRIMP-RG data was collected at the USGS-Stanford SHRIMP-RG in Palo Alto, California. Rock samples for all methods were collected by Mark Carter of the USGS. The whole rock geochemistry and uranium lead isotopic data constrain the age and origin of rocks in the newly defined Dinwiddie Terrane of eastern Virginia.

description: The Eastern Shore of Virginia National Wildlife Refuge (Refuge) is located on the southernmost tip of the Delmarva Peninsula in Northampton County, Virginia. It consists of a variety of habitats including maritime forest, grasslands, fresh and brackish ponds, tidal salt marsh, and beach. The Refuge is considered one of the most important avian funnels along the east coast (Bright and Sagan, 1987); it provides outstanding foraging and sheltering habitat for migrating avian species and productive nursery grounds for fish. In 2001, the Refuge purchased 375 acres of salt marsh down range of the Northampton County small firearms range. The firing range, a two acre in-holding within the Refuge, was formerly owned by the Department of Defense and is presumed to have been active since the 1930s. In this study, we investigated contaminant levels in soils and sediments in the marsh down range of the firing range and along the Virginia Inside Passage to assess whether contaminants are present at levels that would pose an ecological threat. Samples were also collected from the marsh for lead shot or bullet density determination to assess whether lead ingestion would pose a threat to birds or other biota. Lead shot or bullets were not found in any sediment samples. Only one sample, from the marsh, exceeded the lead Effects Range Low (ERL) level, but it was below the Effects Range Median (ERM) and Probable Effect Levels (PEL). Arsenic was above the ERL level in seven of the eight marsh samples but did not approach either ERM or PEL levels. Nickel was above the ERL level in two of the eight marsh samples, but was below the ERM and PEL values. Five organic compounds - acenaphthene, anthracene, dieldrin, DDE, and total PCBs - were detected above their ERL levels. Only two of those analytes, dieldrin and DDE, were above their ERM levels. Of the two samples in which dieldrin was above the ERL, only one was above the PEL. The DDE level was above the ERM level in one marsh sample. This study indicates the soil and sediment pose no threat to wildlife from lead or other contaminants levels and there is no risk of lead poisoning to wildlife via ingestion. The few cases in which contaminant levels were elevated are localized and do not pose a widespread threat to biota. The ERL is a conservative level and although some levels were higher than the ERL, the risk those levels pose to wildlife is negligible.; abstract: The Eastern Shore of Virginia National Wildlife Refuge (Refuge) is located on the southernmost tip of the Delmarva Peninsula in Northampton County, Virginia.

Apatite [Ca5(PO4)3F], titanite [CaTiSiO5], and rutile [TiO2] samples were collected by the U.S. Geological Survey (USGS) from the Coles Hill uranium deposit, Virginia. The samples (in the form of polished thin sections) were prepared and analyzed for direct age dating on a laser ablation inductively coupled plasma mass spectrometer (LA–ICPMS) system at the USGS in Denver, Colorado from August 2017 to March 2019.

The table Virginia Tech vs. MDEQ Results Comparison is part of the dataset Lead Results From Tap Water Sampling in Flint, available at https://redivis.com/datasets/ws5a-390wrpycz. It contains 26 rows across 5 variables.

This table assigns each occupation to only one CTE career cluster and pathway. Although many occupations could reasonably be assigned to more than one career cluster or pathway, limiting this assignment to only one is necessary when the data are used for official labor market projections or for any other planning or administrative applications where double-counting of occupations across pathways or clusters might lead to erroneous conclusions.

ITT Exelis is an active manufacturing complex. Operations have been ongoing since 1958. Currently ITT Exellis employs approximately 1400 employees. The facility consists of three major buildings and associated infrastructure located on two parcels of land in Roanoke, Virginia. EPA issued the facility two EPA identification numbers because the parcels are not contiguous. RCRA Corrective Action activities at this facility were conducted under an EPA Region 3 Section 3008(h) Corrective Action Consent Order. The implementation of the Final Remedy is thru the Facility-Lead CMI agreement with ITT, signed in 2009.

On July 10, 2009, EPA issued the Final Decision and Response to Comments (FDRTC) for the ITT site. In accordance with that decision, ITT Exelis has continued to remediate groundwater at both Building 1 and Building 3 locations.
