#     * DRW Source Codes:   Source of data in the  DRW column:
#
#       MCL = EPA maximum contaminant 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, 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).
