Shenandoah National Park - University of Virginia Primary Project Water Quality Data from 1979-2024 as of 2025-12-17

This data package was created 2025-12-17 14:19:30 by NPSTORET and includes selected project, location, and result data.
The included project (SHEN_UVA_Primary) comprises data from the following sources: (1) the Shenandoah Watershed Study (SWAS); (2) quarterly sampling for the Virginia Trout Stream Sensitivity Study (VTSSS); and (3) 1987, 2000, 2010, and 2011 ('decadal') sampling for the Virginia Trout Stream Sensitivity Study. The Shenandoah Water Study (SWAS), initiated in 1979, has both scientific and resource management objectives. The underlying scientific objective of the SWAS program has been to improve understanding of hydro-biogeochemical processes and factors that govern ecosystem conditions in the mountain watersheds of Shenandoah National Park (SHEN). This scientific objective complements a resource management objective that has been defined by the need to document and assess change that is occurring in SHEN ecosystems.

Only the data from SWAS and VTSSS collected within SHEN are contained in the SHEN_UVA_Primary project. Other data from these programs collected outside SHEN (e.g., on U.S. Forest Service and other lands) can be obtained from the University of Virginia or the Water Quality Portal under the USFS_UVA_Primary and OTHR_UVA_Primary projects.

Data contained in the Shenandoah National Park - University of Virginia NPSTORET back-end file (UVA_NPSTORET_BE_20251212.ACCDB) were filtered to include:

Project:
- SHEN_UVA_PRIMARY: University of Virginia's Primary SWAS-VTSSS Program Database
Station:
- Include Trip QC And All Station Visit Results
Park/Unit Code:
- SHEN
Activity Start Date (>=1/1/1950 and <=12/31/2024)

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 data table
- 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 1979-11-02 to 2024-12-30.  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:
