Data from a 2004 Shenandoah National Park - University of Virginia Project on Mercury Concentrations in Brook Trout in Shenandoah National Park

This data package was created 2025-01-14 15:31:32 by NPSTORET and includes selected project, location, and result data.

Data are from a project to determine the distribution, abundance, and variability of mercury in brook trout in Shenandoah National Park. The purpose of the study was to: (1) provide data needed to evaluate the human health risks associated with the consumption of contaminated fish in Shenandoah National Park; (2) determine the potential for acute or chronic problems with trout populations associated with mercury accumulation and toxicity; and (3) improve understanding of the factors governing the bioavailability of mercury in stream ecosystems.

Data contained in Shenandoah National Park - University of Virginia NPSTORET back-end file (NPS_UVA_NPSTORET_BE_20250108.ACCDB) were filtered to include:

Project:
- SHEN_UVA_HG_BROOK_TROUT_2004: Effects of Stream Water Chemistry on Mercury Concentrations in Brook Trout in Shenandoah National Park
Station:
- Include Trip QC And All Station Visit Results
Park/Unit Code:
- SHEN
Value Status:
- Accepted or Certified (exported as Final) or Final

The data package is organized into five data tables:
- Projects.csv - describes the purpose and background of the monitoring efforts
- Locations.csv - documents the attributes of the monitoring locations/stations
- Results.csv - contains the field measurements, observations, and/or lab analyses for each sample/event/data grouping
- HUC.csv - enumerates the domain of allowed values for 8-digit and 12-digit hydrologic unit codes utilized by the Locations datatable
- Characteristics.csv - enumerates the domain of characteristics available in NPSTORET to identify what was sampled, measured or observed in Results

Period of record for filtered data is 2004-06-03 to 2004-08-03. This data package is a snapshot in time of one National Park Service project. The most current data for this project, which may be more or less extensive than that in this data package, can be found on the Water Quality Portal at:
