Benchmarks Used in the Appendix Graphs

in the NAWQA Summary Reports, 2004

Water Quality Benchmarks were selected by NAWQA national synthesis teams, for use in the NAWQA Summary Reports. These benchmarks consist of maximum contaminant levels and health advisories for drinking water, criteria for the protection of aquatic life, and criteria for the protection of fish-eating wildlife.

An earlier set of reports was published in 2000 and 2001, which used a slightly different set of Benchmarks and constituents. See those at: 2000, 2001 Summary Report Benchmarks

Table 1 shows the benchmarks used in the 2004 Summary Report Appendix Graphs. Below the table is the collection of Codes used in the benchmark columns, and a list of References defining each of the benchmark Codes.

#      DRW Source Codes:   Source of data in the  DRW column:
#
#	MCL = EPA maximum contaminant level in drinking water
#	
#	ACT = EPA action level in drinking water
#	
#	HAL = EPA lifetime health advisory, assumes consumption of 2 L of 
#	water per day over a 70 year lifetime by a 70-kg adult, and that 
#	20% of exposure comes from drinking water
#	
#	RSD5 = Risk-specific dose @ Cancer risk level=10E-5.  For potential 
#	carcinogens only.  
#	
#	NOTE: RSD5(Risk level=10E-5) = RSD4(Risk level=10E-4) / 10.
#
#
#
#	References for human-health benchmarks: 
#	
#	MCL, ACT, HAL, and RSD5 values are from USEPA (2002c) unless 
#	noted otherwise.  A few RSD5 values are from USEPA (2002a), as 
#	noted in database. Also, drinking water regulations for some 
#	constituents have changed recently, so these benchmarks have 
#	additional sources: arsenic (USEPA, 2001a,b), radon 
#	(USEPA, 1999a, 2000b), and uranium (USEPA, 2000c, 2001c, 2002b).
