VOC Occurrence Maps

The following maps show VOC occurrence across the nation and were developed using the data set described in USGS Circular 1292. These maps include NAWQA data as well as historical data sets collected before the NAWQA program began, and other data sampled as part of the AWWARF study of the public supply wells. They are provided in Adobe PDF format.

Interactive maps of VOC results may be created (from NAWQA data only) at the NAWQA Data Warehouse site at http://water.usgs.gov/nawqa/data.
