Revision History for Circular 1332 By Leslie A. DeSimone, Pixie A. Hamilton, and Robert J. Gilliom Quality of Water from Domestic Wells in Principal Aquifers of the United States, 1991–2004 Overview of Major Findings ----------------------------------------------------- Posted online March 20, 2009 ----------------------------------------------------- Revised and reposted September 24, 2009 Subsequent to publication of U.S. Geological Survey Circular 1332, “Quality of Water from Domestic Wells in Principal Aquifers of the United States, 1991-2004—Overview of Major Findings,” a typographical error was found in table 3 of the report. The human-health benchmark (U.S. Environmental Protection Agency Maximum Contaminant Level or MCL) for ethylene dibromide was incorrectly listed as 0.1 microgram per liter in table 3 on page 29. The correct value is 0.05 microgram per liter. The correct value was used in all data analysis and interpretation; consequently, the error does not affect any related text, interpretation, or conclusions. ----------------------------------------------------------------------
