Sites within Virginia where DEQ or other data providers have collected water column, sediment, fish tissue or benthic macroinvertebrate samples within the given assessment data window (2016). Attributes assigned to each station are summarized based on samples collected per station ID. QA/QC checks are performed on the database to verify attribute and spatial accuracy, however errors may still occur. Please direct any questions about attribute accuracy to the Data Distributor. The geospatial product is maintained and updated by VA DEQ each assessment cycle (biennially) using the most current data provided. Stations not monitored within the given data window may be included for clarification of assessment unit ID status but have no data within the parameter columns. See the Comments fields for those instances. Complete FGDC compliant metadata is provided with the data which contains contact information, process steps, attribute descriptions, and distribution information. |
