# * 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).
