Please read this document first before viewing the files in Appendix 3 of U.S. Geological Survey Scientific Investigations Report 2009-5139. The databases used in this report are zipped in the folder Appendix3.zip. The files include the following: BASELINE_OCCURRENCE2003a.Monitoring.xls BASELINE_OCCURRENCE2003b.Monitoring.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for wells sampled for the Blue Ridge crystalline and Triassic Lowland siliciclastic hydrogeologic setting baseline-assessment area, 2003, in Microsoft Office Excel 97-2003 format (xls). Because of Microsoft Excel space limitations, two files were needed to provide results for all compounds analyzed. BASELINE_OCCURRENCE2004Monitoring.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for wells sampled for the Eastern Lake surficial hydrogeologic setting baseline-assessment area, 2004, in Microsoft Office Excel 97-2003 format (xls). BASELINE_OCCURRENCE2005Monitoring Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for wells sampled for the Devonian-Silurian carbonate hydrogeologic setting baseline-assessment area, 2005, in Microsoft Office Excel 97-2003 format (xls). BASELINE_OCCURRENCE2006Monitoring Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for wells sampled for the Great Valley siliciclastic hydrogeologic setting baseline-assessment area, 2006, in Microsoft Office Excel 97-2003 format (xls). BASELINE_OCCURRENCE2007Monitoring.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for wells sampled for the Northeastern Glaciated surficial hydrogeologic setting baseline-assessment area, 2007, in Microsoft Office Excel 97-2003 format (xls). CHANGEMonitoring_VulnerableSettings.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for wells in baseline-assessment areas (four settings vulnerable to pesticide contamination), 2003 and 2004, in Microsoft Office Excel 97-2003 format (xls). HOT-SPOTWellBA437SeasonalMonitoring.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for hot-spot well BA 437, 2003 to 2007, in Microsoft Office Excel 97-2003 format (xls). HOT-SPOTWellLN1842SeasonalMonitoring.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for hot-spot well LN 1842, 2003 to 2007, in Microsoft Office Excel 97-2003 format (xls). HOT-SPOTWellBE1370SeasonalMonitoring.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for hot-spot well BE 1370, 2003 to 2007, in Microsoft Office Excel 97-2003 format (xls). HOT-SPOTWellsandNeighborWells.xls Local number, station number, dates and times of sample collection, depth of well, depth to water level, and field parameter and water-quality results for three hot-spot and neighboring wells, 2005 and 2006, in Microsoft Office Excel 97-2003 format (xls).
