Notices
This document contains information regarding the calculation of the human health criteria
contained in the document entitled, National Recommended Water Quality Criteria: 2002. This
document provides: cancer potency factors (ql*s); reference doses (RfDs); relative source
contributions (RSCs); fish intake values; and equations used to derive the human health criteria
in the aforementioned compilation.
This document is not a regulation and cannot substitute for the Clean Water Act or
Environmental Protection Agency (EPA) regulations. Thus, the criteria in the calculation matrix
cannot impose legally binding requirements on EPA, states, authorized tribes or the regulated
community.

FOOTNOTES :
1. IRIS values as of May 17,2002 are presented. IRIS information is presented in some cases even though it may not be used to calculate criteria. All units are as follows:
ql * = per mg/kg-day; RfD = mg/kg-d; BCF = L/kg; and FI = 17.5 g/day (unless otherwise noted).
2. Calculations are based on the following methodologies: Guidelines and Methodologies Used in the Preparation of Health Effects Assessment Chapters of the Consent Decree Water Criteria
Documents (45FR79347) and Methodology for Deriving Ambient Water Quality Criteria for the Protection of Human Health (2000), EPA-822-B-00-004, October 2000).
3. Reference cite refers to an IRIS coversheet, AWQC criterion document or other document which serves as the basis for the criterion.
4. Although a new RfD is available in IRIS, the surface water criteria will not be revised until the National Primary Drinking Water Regulations: Stage 2 Disinfectants and Disinfection Byproducts
Rule (Stage 2 DBPR) is completed, since public comment on the relative source contribution (RSC) for chloroform is anticipated.
5. In IRIS, EPA has listed thallium sulfate, not thallium alone. The thallium RfD included in the matrix is based on: NOAL = 0.25 mg TL2SO4/kg-d; UF = 3000; fraction TL in
TL2SO4 = 0.81.
6. Original 1980 ADIs were expressed as mg/day. These have been converted to mg/kg-day to make them comparable to present day RfDs. All ql *s are in kg-day/mg or
per mg/kg-day.
7. The fish tissue bioconcentration factor (BCF) from the 1980 criteria documents was retained unless otherwise noted. No BAFs were derived for this effort.
8. Criteria based on carcinogenicity (ql *), reflect 10"6 risk.
9. The ql * of 1.75 mg/kg-d was derived from the risk per unit concentration in drinking water from IRIS: 5xlO"5 risk per ug/L in drinking water.
10. This criterion was not revised as part of this effort. EPA has published revisions for this criterion in the Federal Register and is soliciting scientific views on the revised value.
11. Although a ql * and RfD are available in IRIS, the ql *was used to derive the criterion because it resulted in the more stringent criterion.
12. These criteria were not published or promulgated in the NTR or CTR. These criteria were calculated based on the RfD presented in IRIS.

RfD = Reference dose mg/kg-d
DI = Drinking water intake 2 L/day
BW = Human body weight 70 kg
FI = Fish intake 0.0175 kg/day
BCF = Bioconcentration factor F/kg
UF = Uncertainty factor (unitless)
