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.

Map Tab-- explore the data interactively and download data for individual sampling sites. Map layers include:

Result averages (group) -- state-wide results for one or more common parameters, such as Aluminum, pH, Conductivity, etc.

  • 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 -- this is the primary interactive layer.

  • click on features from this layer to add to the station list in the right panel
  • click on the 'i' icon for a station to display:
    • details about the station
    • graph results for each parameter.
    • download data for this station

303d & tier3 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 the 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.
