NOTE: The data provided in this report differs from the information provided in the original Pennsylvania 2006 Integrated Water Quality Monitoring and Assessment Report. This is a result of differences between the Pennsylvania State assessment database and the summary data provided in Pennsylvania's 2006 Integrated Report, which is available at http://www.depweb.state.pa.us/watersupply/cwp/view.asp?a=1261&q=480056.

Site-specific Targeted Monitoring Summary Results

Pennsylvania (2006)

Description of this table

For the 2006 Integrated Report Cycle, the total assessed waters size is greater than the total waters size for the EPA Waterbody Type Rivers and Streams in Pennsylvania. This discrepancy was identified after the release of the data, and is likely due to the improvements in mapping state waters.
