#  METADATA Data Description:  
#
#  ABSTRACT: This data set contains the Seasonal Kendall results for Diazinon trends test in surface water 
#	from 1997 to 2004 for 12 seasons.  Details on the trend test are provided in Phillips and others, 2007 
#	(DOI 10.1021/es070301+).  The data was used for sites VA1 and IL4 in Supporting Figure 2 in a 
#	report documenting Temporal Diazinon trends in surface water insecticide concentration as a part 
#	of the U.S. Geological Survey, National Water Quality Assessment Program.
#
#  SUPPLEMENTAL INFORMATION:
#   	PROCEDURES USED:
#	PROCESS STEP:
#
#	Original diazinon concentration data was pulled for NAWQA sites from the NAWQA Data Warehouse in 
#	October 2005 and imput through a Seasonal Kendall trend test to give the data set detailed here.  
#	Note: Site MA2 did not have a Seasonal Kendall Trends run.  Original diazinon concentrations can be found 
#	for each site under "Insecticide Concentration Data - Diazinon.conc.txt" under the following listed 
#	relatedspatial and tabular data sets.  
#
#	STREND was run on the USGS module for STREND in SPLUS on a PC based version in the 2004-2006 time	
#	frame.  This module is cited in Phillips and others, 2007 (22).  Output from the Seasonal Kendall Test yeilds TREND
#	and TREND.PCT in units units/year and percent/year respectively.
#
#	Trend Significance was determined by estimated P-Values for Diazinon concentration trend over time for
#	each site.  Significance was flagged if P-Values were equal to 0.1 or less, or determined not significant if larger.
#	Only significant decreasing trends were found.
#
#  Related Spatial and Tabular Data Sets:  
#         	
#	All files listed below were used in the analysis for the report Phillips and others, 2007 (DOI 10.1021/es070301+).
#	These files are all being documented and archived for this report.
