This report presents results of surface-water-quality data retrievals for Cumberland Gap National Historical Park from six U.S. EPA national databases (STORET, RF3, IFD, DRINKS, GAGES, DAMS). It provides a complete inventory of retrieved water quality parameter data and stations, descriptive statistics and graphical plots characterizing period of record and trends, comparisons to EPA and WRD screening criteria, and an Inventory Data Evaluation and Analysis to determine which Level I parameters have been measured. Accompanying disks contain digital copies of all data and report components.
