About

This application is a combined interactive map and data download resource for the WABbase database. WABbase is a water quality database maintained by the Division of Water and Waste Management of the West Virginia Department of Environmental Protection. The database includes over 2 million results for nearly 300 parameters sampled from over 15,000 sample locations throughout the state.

  • 2M+results
  • ~300parameters
  • 15,000+sample locations

Map tab

Explore the data interactively and download data for individual sampling sites. Map layers include:

Result averages (group)

Statewide results for one or more common parameters, such as aluminum, pH and conductivity.

  • Symbols vary by the average of all the results for one parameter.
  • Numerical values are labeled at large scales.
  • Multiple layers can be selected and labeled at the same time.

Stations

The primary interactive layer.

  • Select features from this layer to add them to the station list in the right panel.
  • Select the details button for a station to display:
    • details about the station
    • graphed results for each parameter
    • a data download for the station

303(d) and Tier 3 streams

Streams included on the 2016 impaired streams list. Individual layers are available for specific impairments, including:

  • Manganese
  • PCBs
  • Selenium
  • Iron
  • Aluminum
  • Fecal/Bacteria
  • pH

WV hydrology

Reference layer for stream names and watersheds used by WVDEP.

  • Visibility and symbols are based on total miles of streams above each segment.
  • Stream labels include WVDEP's AUID code at large scales.
  • Large (8-digit) watersheds use WVDEP names for consistency with TMDL assessments.

Download tab

Download data for individual watersheds at the 8-digit, 10-digit or 12-digit level.
